New faunistic and taxonomic data are provided for 19 families of Iranian spiders. Stemonyphantes arta Esyunin et Zamani, sp. nov. (Linyphiidae) is described from a male and a female collected in the Zanjan Province. Five genera of the family Theridiidae (Pholcomma, Phoroncidia, Phycosoma, Rhomphaea and Rugathodes) and 21 species are recorded from Iran for the first time, and 119 new province records are provided for 51 species. Additionally, Megarctosa bamiana Roewer, 1960 (Lycosidae) is transferred to the genus Arctosa C.L. Koch, 1847. A mistake in the original description of Gnaphosa azerbaidzhanica Tuneva et Esyunin, 2003 (Gnaphosidae), namely a mismatch of the figures of this species with those of G. tigrina Simon, 1878, is discussed and corrected here. Considering the results presented in this paper, the total number of spiders recorded from Iran is raised to 888 species in 321 genera.

Detailed Work

Background The megalichthyids are one of several clades of extinct tetrapodomorph fish that lived throughout the Devonian–Permian periods. They are advanced “osteolepidid-grade” fishes that lived in freshwater swamp and lake environments, with some taxa growing to very large sizes. They bear cosmine-covered bones and a large premaxillary tusk that lies lingually to a row of small teeth. Diagnosis of the family remains controversial with various authors revising it several times in recent works. There are fewer than 10 genera known globally, and only one member definitively identified from Gondwana. Cladarosymblema narrienense Fox et al. 1995 was described from the Lower Carboniferous Raymond Formation in Queensland, Australia, on the basis of several well-preserved specimens. Despite this detailed work, several aspects of its anatomy remain undescribed. Methods Two especially well-preserved 3D fossils of Cladarosymblema narrienense, including the holotype specimen, are scanned using synchrotron or micro-computed tomography (µCT), and 3D modelled using specialist segmentation and visualisation software. New anatomical detail, in particular internal anatomy, is revealed for the first time in this taxon. A novel phylogenetic matrix, adapted from other recent work on tetrapodomorphs, is used to clarify the interrelationships of the megalichthyids and confirm the phylogenetic position of C. narrienense. Results Never before seen morphological details of the palate, hyoid arch, basibranchial skeleton, pectoral girdle and axial skeleton are revealed and described. Several additional features are confirmed or updated from the original description. Moreover, the first full, virtual cranial endocast of any tetrapodomorph fish is presented and described, giving insight into the early neural adaptations in this group. Phylogenetic analysis confirms the monophyly of the Megalichthyidae with seven genera included (Askerichthys, Cladarosymblema, Ectosteorhachis, Mahalalepis, Megalichthys, Palatinichthys, and Sengoerichthys). The position of the megalichthyids as sister group to canowindrids, crownward of “osteolepidids” (e.g.,Osteolepis and Gogonasus), but below “tristichopterids” such as Eusthenopteron is confirmed, but our findings suggest further work is required to resolve megalichthyid interrelationships.

First Time

During a survey of intertidal zones at beaches on Jeju Island, two species belonging to the family Thoracostomopsidae were discovered. One new species, Enoploides koreanus sp. nov. and one known species, Epacanthion hirsutum Shi & Xu, 2016 are reported. Along with morphological analysis, mitochondrial cytochrome oxidase c subunit 1 (mtCOI) sequences and 18S rRNA sequences of the species were also obtained and used to check relative p-distance and phylogenetic positions. While most species of Enoploides have long spicules, the new species belongs to a group of Enoploides with short spicules < 150 µm). Of the seven species with short spicules, the new species is most closely related to E. disparilis Sergeeva, 1974. They both have similar body length, fairly similar sized and shaped spicules with small gubernaculum running parallel to distal end of spicule, and an index value of b. The new species can be distinguished from E. disparilis by having pre-anal supplementary organ with short conical tail, while E. disparilis lacks pre-anal supplementary organ and has a long conico-cylindrical tail. Along with the description of the new species, the genus Enoploides Ssaweljev, 1912 is bibliographically reviewed and revised. Of 45 species described to date, 27 are now considered valid, 16 species inquirendae due to inadequate descriptions and ambiguity of the material examined, along with two cases of nomen nudum. With this review, we provide an updated diagnosis and list of valid species, a tabular key comparing diagnostic characters of all valid species, and a new complete key to species. One known species, Epacanthion hirsutum Shi & Xu, 2016, is reported in Korea for the first time. The morphology agrees well with the original description provided by Shi & Xu, 2016. As they had already reviewed the genus at the time of reporting four Epacanthion species, we provide only a description, depiction, and measurements for comparison purposes.

First Time

The present study reviews the taxonomy of the marine gastropods belonging to the family Eulimidae Philippi, 1853 from the continental slope off Northeast Brazil. The genera Abyssoaclis Barros, Mello, Barros, Lima, Santos, Cabral & Padovan, 2003 and Aclis Lovén, 1846 were not treated here. A total of 20 taxa were identified in this region, excluding Eulima hebes Watson, 1883, a species with a doubtful classification in Eulimidae. The species were assigned to the following genera: Costaclis Bartsch, 1947, Eulima Risso, 1826, Fusceulima Laseron, 1955, Melanella Bowdich, 1822, Ophieulima Warén & Sibuet, 1981, Sticteulima Laseron, 1955, Thaleia Warén, 1979, and Umbilibalcis Bouchet & Warén, 1986. The genera Sticteulima, Ophieulima and Umbilibalcis are reported for the first time in the southwestern Atlantic. Four species represent new records for the southwestern Atlantic. A redescription of the shell morphology is provided for: Costaclis egregia (Dall, 1889b), Melanella doederleini (Brusina, 1886), and Umbilibalcis lata (Dall, 1889b). Additional information to the original description are reported for other species. Melanella sarissa is considered as a synonym of Melanella cinca Dall, 1927. Six new species are described: Eulima cracentis sp. nov., Melanella paraabida sp. nov., M. adiastalta sp. nov., M. anapetes sp. nov., Sticteulima cabrali sp. nov. and S. canopusensis sp. nov. Lectotypes are designated for: Costaclis hyalina, C. egregia, Eulima ephamilla (Watson, 1883), E. psila and E. (?) hebes. Eulima sp. 1, Melanella sp. 1 and Melanella sp. 2 are potential new species, but the scarcity of material precludes a formal description at this moment.

Abstract In this research, we report the presence of two ciliate protozoans of the subclass Peritrichia, Cothurnia amphicteis and C. peloscolicis, as epibionts on the chaetae of scaled polychaetes Malmgrenia lilianae, M. andreapolis (fam. Polynoidae) and Sthenelais boa (fam. Sigalionidae), from the north Adriatic (Mediterranean Sea). Both ciliate species are herein found for the first time after their original description and are redescribed, based on light and scanning electron microscopy analyses. This is the first record of an association between ciliates and polychaetes of the family Sigalionidae. Our results suggest that these host–epibiont relationships might be highly specific. We also present the first review of epibiosis between polychaetes and peritrich ciliates, indicating that this relationship is more diverse than previously thought. Forty taxa of peritrich ciliates from 12 genera and seven families are recorded as epibionts on polychaetes, while 48 polychaete taxa are known as their hosts. The relationship can be considered ectocommensalism, where the ciliates have the advantages of increased food availability. This association might be a more widespread phenomenon than currently known, because it could be easily overlooked or misinterpreted. It, therefore, deserves careful attention and further investigation.

We describe two species from the genus Triconia Böttger-Schnack, 1999 in the family Oncaeidae from the northeastern equatorial Pacific, both belonging to the conifera-subgroup. Both sexes of T. derivata (Heron & Bradford-Grieve, 1995) are redescribed, including morphological features not noted in earlier descriptions, such as the posterior face of the labrum. Specimens of T. derivata from the northeastern equatorial Pacific differ slightly from the original descriptions in some morphometric characters, and their differentiation from T. furcula (Farran, 1936), which is closely related, is summarized. The male of T. hirsuta Wi, Böttger-Schnack & Soh, 2010 is described for the first time and the morphology of the female is redescribed. The female holotype of T. hirsuta from Korean waters is reexamined and discrepancies between text and figures in the original description regarding the endopodal spine lengths on swimming leg 2 are clarified. A revised version of the respective part of the original figure is included in the present paper. An indication of the variation in endopodal spine lengths on swimming legs 2 to 4 is provided for both sexes of the two species. It is pointed out that morphometric characters required for unequivocal identification of species of the conifera-subgroup are still not sufficiently well defined. The records of T. derivata and T. hirsuta to date are summarized and indicate a wide zoogeographical distribution of the former species.

One New Species

With the complexity of the family Phyllidiidae and the problems of identification in the Indo-West Pacific, the story of the Red Sea species continues to unfold. One new species and one new record are added to the Red Sea fauna, both belonging to the genus Phyllidiella. Phyllidiella amphitritesp. nov. is described from a single specimen from the northern Red Sea and clearly differs from all species of Phyllidiella in having pale yellow pigment on the tubercles. Phyllidiella zeylanica is newly recorded from the Red Sea with five specimen records and several photographed individuals; other than this, it has a western Indian Ocean distribution. Phyllidia schupporum was collected for the first time since its original description; because its distribution is now extended to the Persian Gulf, it is no longer considered endemic to the Red Sea. The distribution of the Red Sea endemic Phyllidia dautzenbergi is extended northwards to Hurghada, Egypt. A small specimen of the endemic Phyllidiopsis sinaiensis was found at 214–237 m depth just at the mouth of the Red Sea, which is a bathymetrical range extension from its previous shallow coral reef records. The identifications of other species are revisited. A new species of Paradoris is described as Paradoris hypocritasp. nov., differing from the well-known but localised West Pacific P. liturata which also resembles a phyllidiid. This new species was recorded many years ago by published photographs, and it is relatively common in the Red Sea, evidenced by several specimens and additional photographs. It is described herein, and is considered a Red Sea endemic, differing from both the unnamed Indian Ocean species and the named Pacific species.

The family Amphipterygidae comprises a group of moderately large, robust species of pan-tropical damselflies. It was first recognized by Selys (1853) as his "6me legion" based on the description of a unique female which he named "Amphipteryx agrioïdes." Its provenance ("Colombie. [Collect. Selys.]") has remained a mystery as no specimens of this genus had subsequently been collected from South America. Selys (1854a: 241, 243) expanded on the distribution of the specimen noting (page 241) that it had been collected “dans la province de Cumana (Amérique méridionale équatoriale)” and (page 243) “d’après un exemplaire recueilli par M. Funck, et qui se trouvait avec l’ Hetaerina majuscula et l’ Agrion (Hyponevra) Funcki….” De Marmels (1990) dismissed the record of A. agrioides from “Cumaná [Venezuela]” as unlikely and suggested deletion of the species from that country.The single holotype female was apparently never re-examined, except by the late B.E. Montgomery who never published his observations, until recently (von Ellenrieder & Garrison 2007). Calvert (1901) in his Biologia Centrali-Americana assigned this name to specimens from Mexico and Guatemala. He described the male for the first time and gave a description of the female comparing it with the original description and noting that "The hind prothoracic lobe also possesses two dorsal lamellate processes (not mentioned by Selys)…." González (1991) described A. longicaudatus (should be A. longicaudata; Novelo 1995) from Oaxaca, Mexico and distinguished this species from A. agrioides based only on Calvert's (1901) description and illustrations. Several years ago, Rosser W. Garrison was sent digital images of the holotype female of A. agrioides by Jérôme Constant of the IRSNB, and observed that the pronotal armature differed from specimens given this name by Calvert (1901) and González (1991) (Garrison pers. comm.). Since Amphipteryx is the type genus of the family Amphipterygidae, it is imperative that its type species, A. agrioides, be correctly assigned to specimens. The purpose of this paper is to determine the correct identity of A. agrioides, provide diagnostic illustrations of the same, and discuss the location of its type locality.

During a recent survey, 29 earthworm species were collected from different parts of Turkey, 27 of which belong to the family Lumbricidae, one to Acanthodrilidae and one to Megascolecidae. Dendrobaena proved to be the most speciose genus with 12 recorded species including two species new to science, Dendrobaena pavliceki and Dendrobaena taurica spp. nov. In addition a third new species was also found belonging to the East Mediterranean genus Healyella: Healyella zicsii sp. nov. From the species recorded earlier for Turkey, D. fridericae uludagi Omodeo & Rota, 1991 and He. boluana Omodeo & Rota, 1989 were found for the first time since the original description. With these new records the number of earthworm species recorded for Turkey is raised to 84.

Critical Consideration

Initially, Oliver Twist (1839) might seem representative of the archetypal male social plot, following an orphan and finding him a place by discovering the father and settling the boy within his inheritance. But Agnes Fleming haunts this narrative, undoing its neat, linear transmission. This reconsideration of maternal inheritance and plot in the novel occurs against the backdrop of legal and social change. I extend the critical consideration of the novel's relationship to the New Poor Law by thinking about its reflection on the bastardy clauses. And here, of course, is where the mother enters. Under the bastardy clauses, the responsibility for economic maintenance of bastard children was, for the first time, legally assigned to the mother, relieving the father of any and all obligation. Oliver Twist manages to critique the bastardy clauses for their release of the father, while simultaneously embracing the placement of the mother at the head of the family line. Both Oliver and the novel thus suggest that it is the mother's story that matters, her name through which we find our own. And by containing both plots – that of the father and the mother – Oliver Twist reveals the violence implicit in traditional modes of inheritance in the novel and under the law.

Kehamilan remaja adalah kehamilan yang terjadi pada remaja berusia kurang dari 20 tahunan. Kehamilan remaja memberikan banyak kerugian bagi kesehatan, mental dan psikologis, kesejahteraan ekonomi dan peluang karier, kemiskinan dan prospek kehidupan masa depan remaja. Tujuan penelitian mengidentifikasi faktor determinan yang melatarbelakangi terjadinya kehamilan remaja. Jenis penelitian adalah penelitian analitik kategorik jenis survei kuantitatif dengan desain case control. Populasi semua perempuan yang bertempat tinggal di wilayah dusun Wonosari, Sukosari, dan Krajan Pandansari dan pernah/sedang hamil pertama kali pada usia kurang dari 20 tahun. Teknik pengambilan sampel cluster random sampling besar sampel 73. Berdasarkan hasil model akhir analisis multivariat, diketahui bahwa variabel pendidikan, riwayat kehamilan remaja pada keluarga dan usia menikah merupakan variabel yang berhubungan dengan kejadian kehamilan remaja setelah dikontrol oleh variabel akses informasi, responden berpendidikan rendah memiliki peluang 20,8 kali lebih tinggi, responden yang memiliki riwayat kehamilan remaja pada keluarga memiliki peluang 14,9 kali lebih tinggi, responden yang menikah pada usia <20 tahun memiliki peluang 12,1 kali lebih tinggi, responden dengan pemahaman yang kurang baik terkait penggunaan kondom memiliki peluang 5,9 kali lebih tinggi untuk terjadi kehamilan remaja. Oleh karena itu perlu dibangun karakter buiding, sosial karakter suport untuk para ibu remaja dan keluarga sehingga terbangun interaksi yang baik dalam keluarga yang dilandasi dengan pendidikan dan pemahaman yang baik tentang Pendidikan seksualitas. Teen pregnancy is a pregnancy that occurs in adolescents aged less than 20 years old. Teen pregnancy provides many disadvantages for health, mental, psychological, economic well-being, career opportunities, poverty, and the future life. The aim of the study was to identify the determinants underlying teen pregnancy incidence. This study was a quantitative study with categorical analytic method. The study design used a case control with two comparison groups. The groups were control group and case group. The population in this study was all women who lived in the Wonosari, Sukosari, and Krajan Pandansari district and had or were pregnant for the first time at the age of less than 20 years old. Seventy three respondents were recruited using cluster sampling technique. The case group consists of women who were or had pregnant for the first time at the age of less than 20 years old and their children are currently aged ≤ 1 years old. The control group consists of women who were pregnant for the first time at the age of > 20 years old. The data was collected using a questionnaire. The findings showed that education, history of teen pregnancy in family and the age of marriage were related to the incidence of teen pregnancy after being controlled by information access. Low-educated respondents had 20.8 times higher chance of experiencing teen pregnancy; respondents with a history of teen pregnancy in the family had 4.9 times higher chance of experiencing teen pregnancy; respondents who were married at the age of < 20 years old had 12.1 times higher chance of experiencing teen pregnancy; respondents with poor understanding of condom use had 5.9 times higher chance of teenage pregnancy. In conclusion, the findings suggest to build good interactions in the family based on education and a good understanding of sex education.
