Fifteen species of Marphysa classified in the Subgroup 1 Fauchald (1970) were reviewed and evaluated in a morphological analysis of the subgroup. It was found that 13 of these have a characteristic morphological pattern distinct from that of Marphysa sensu stricto; as a consequence, a new genus is proposed, Paucibranchia n. gen. This new genus includes the species that have branchiae restricted to a few chaetigers in the anterior region, maxillae I with a rounded falcal arch and outer edge with a straight base plus a curvature in the basal inner edge, dorsal cirri longer in the branchial region and in media-posterior region as long or longer than pre-branchial chaetigers, and the postchaetal lobe in the branchial region well developed, elongated. Paucibranchia n. gen. includes six new species (P. andresi n. sp., P. carrerai n. sp., P. gathofi n. sp., P. gilberti n. sp., P. miroi n. sp. and P. patriciae n. sp.), two species not formally named, and other 13 species previously included in Marphysa (P. adenensis (Gravier, 1900) n. comb., P. bellii (Audouin & Milne-Edwards, 1833) n. comb., P. cinari (Kurt-Sahin, 2014) n. comb., P. conferta (Moore, 1911) n. comb., P. disjuncta (Hartman, 1961) n. comb., P. fallax (Marion & Bobretzky, 1875) n. comb., P. gemmata (Mohammad, 1973) n. comb., P. kinbergi (McIntosh, 1910) n. comb., P. oculata (Treadwell, 1921) n. comb., P. purcellana (Willey, 1904) n. comb., P. sinensis (Monro, 1934) n. comb., P. stragula (Grube, 1878) n. comb., P. totospinata (Lu & Fauchald, 1998) n. comb.). One species previously classified in the subgroup, Marphysa striata (Kinberg, 1865), was considered indeterminate. Finally, some statistical analyses on size dependent features and an identification key for species of the new genus were included.

The infraorder Thalassinidea Latreille, 1831 [sensu stricto] includes three families: Thalassinidae Latreille, 1831; Upogebiidae Borradaile, 1903; and Laomediidae De Haan, 1849 (cf. Sakai & Sawada, 2006). However, recent examination of material from Kuwait in the Pershian Gulf, showed the occurence of a new species,Kuwaitupogebia nithyanandangen. et sp. nov., and this has made it possible to establish a new family, Kuwaitupogebiidae fam. nov., based on that new genus. The genusUpogebiaLeach, 1814 is known to include nine species from the Red Sea area, yet herein two new species,Upogebiaspongicolasp. nov. from the Reef at Hurghada, Red Sea, Egypt, andUpogebia jizanensissp. nov. from off Jizan, Saudi Arabia, Red Sea, can be added, based on material lodged in the collections of the museum in Frankfurt a. M.

A new family, Vultocinidae, is established for an unusual new genus and new species of crab (Crustacea: Brachyura: Goneplacoidea) here described from relatively deep waters in the central Philippines and Vanuatu. Although Vultocinus anfractus, new genus, new species, superficially resembles pilumnid genera like Lophoplax and pseudoziid genera like Planopilumnus in its deeply sculptured carapace and leg surfaces, its male abdomen and gonopods appear to affiiliate it with the Goneplacidae sensu lato instead. However, its suite of many unusual characters requires the recognition of a new family for Vultocinus. Comparisons of the Vultocinidae with the Goneplacidae sensu stricto suggests that the subfamily Mathildellinae, presently regarded as a subfamily, should be recognised as a full family; and two other problematic constituent genera, Progeryon and Conleyus, are also referred to their respective families in the Goneplacoidea. The genus Paragalene is also referred to the Progeryonidae. The extent of the sterno-abdominal cavity along the thoracic sternites, structure of the posterior thoracic sternites, position of the press button of the male abdominal locking mechanism and form of the first four male abdominal segment as characters in the taxonomy of the Goneplacoidea is also discussed.

Objective: This study was designed to assess the morphological and histological alterations of the condyle of rats undergoing forward mandibular repositioning via functional appliance. Materials and Methods: Functional appliances were mounted onto the upper jaws of rats. Morphological analysis was conducted on micro-CT images of sacrificed animals. Histological changes in condyle were examined by immunohistochemistry using proliferating cell nuclear antigen (PCNA), matrix metalloproteases (MMPs), vascular endothelial growth factor (VEGF), tissue inhibitors of matrix metalloproteinases (TIMP-1), interleukin 1b (IL-1β), Aggrecan and Type II collagen. Osteoclast activity was identified by tartrate-resistant acid phosphatase (TRAP) staining. Results: Morphological analysis confirmed the forward positioning of the condyles of rats by the appliance, but the position gradually returned to normal on days 14 after treatment. An increase in PCNA positive cells was observed in the posterior region of the condyles on days 7, whereas PCNA positive cells decreased in the anterior region. Aggrecan and Type II collagen localization increased in the posterior region throughout the entire period, but decreased in the anterior region on days 14. In both regions, IL-1β and VEGF localization was significantly increased for 14 days while MMPs localization was evident throughout the entire period. The TRAP positive cells were significantly elevated on days 3 and 7. Conclusions: These results suggest that the functional appliance therapy induces significant morphological and histological changes in the anterior and posterior regions of the condyle and subsequently causes adaptive cellular functions such as chondrocyte differentiation and cartilage matrix formation.

We describe a new genus anda newspecies of Polycladida,Namyhplana henriettae(Platyhelminthes, Euplanidae), which lives associated with the tubes of the bivalveBankia martensiin the fjords of the South Pacific Ocean in Chile. This species is characterized by a ribbon-like body, light brown colour, anterior region devoid of pigment, few eyes, no tentacles, pharynx in the anterior region of the body with few folds, independent gonopores anterior to the medial body line, seminal vesicle strongly muscularized, digitiform penian papilla oriented posteroanteriorly, a curled vagina, and a large Lang's vesicle ventral to the intestine. A phylogenetic analysis of the Euplanidae, based on morphological characters, is presented. With the dataset used, the family Euplanidae does not seem to be a monophyletic group. The new species is closely related toTaenioplana teredini(also discussed here) which presents life-habit characteristics that are similar to those of the new species.

Three new species of heat-resistant fungi related to the hyphomycete Cladosporium staurophorum (Kendrick) M.B. Ellis were isolated from heat-treated soil from commercial lowbush blueberry fields and other sites in eastern Canada. Cladosporium staurophorum and the three new species produce characteristic dark, multicelled chlamy dospores. Phylogenetic analysis of nuclear ribosomal internal transcribed spacer DNA sequences suggest that these four species form a monophyletic group that is marginal in the Mycosphaerellaceae and phylogenetically distinct from Cladosporium sensu stricto. The new genus Devriesia is described for C. staurophorum, the three new species, and a fifth species originally described as Cladosporium chlamydosporis. A key to distinguish the five accepted species is provided. The species of the genus are dimorphic and share similar cladosporium-like conidial anamorphs consisting of pale brown, short, acropetally produced chains of cylindrical to fusiform, zero- or one-septate conidia and ramoconidia, diagnostic chlamydosporic synanamorphs, and a soil-borne, heat-resistant ecology. Devriesia acadiensis N.L. Nickerson & Seifert, with clover-shaped chlamydospores, Devriesia shelburniensis N.L. Nickerson & Seifert, with large, multi celled chlamydospores, and Devriesia thermodurans N.L. Nickerson & Seifert, with few-celled, clavate chlamy dospores, are described as new species. Chlamydospores from cultures of D. acadiensis, Devriesia staurophora, and D. thermodurans germinated after exposure to 75 °C for 30 min. Germination of these spores was activated by a heat shock. Chlamydospores from cultures of C. shelburniensis did not germinate after heat exposure.Key words: dematiaceous hyphomycetes, heat-resistant fungi, lowbush blueberries, Vaccinium angustifolium, ITS rDNA phylogeny.

The genus Acrophyma Bergroth currently contains two species, the Andean A. cumingii (Westwood) and the Neotropical A. bicallosa (Stål). The examination of types and new material revealed that among the Neotropical species the Brazilian population differs from the Colombian, and the first one belongs to a new species in this group. A morphological analysis of the genus indicated the Neotropical species are different from the Andean species. According to the current most used generic characters in acanthosomatids, Neotropical species should be placed in a new genus. This is also supported by biogeographical relationships. New distributional records for the species of this group are provided.

AbstractAfrotheora, a new hepialoid genus from central and southern Africa, is described. There are eight species of which seven are named. Three were described previously, but were assigned to other genera (Dalaca rhodaula Meyrick, Eudalaca jordani Viette, and Hepialus thermodes Meyrick - a new senior synonym of Hepialus pardalias Janse). Four new species are named and described (minirhodaula, argentimaculata, flavimaculata and brevivalva). A further new species is described, but is not formally named. All species and their genitalia are described and illustrated. Three new combinations and one new synonymy are established, two lectotypes are designated and Hepialus ptiloscelis Meyrick from South Africa is transferred to Gorgopis Hübner. The monophyly of Afrotheora is recognized by the possession of two unique characters: (1) long bristle-like setae from the antennal scape reaching almost across the compound eye, and (2) the trulleum in the male genitalia comprising two lateral sclerotized rods separated by a membrane. Afrotheora represents one of the 12 hepialoid basal lineages currently thought to be monophyletic, and it is demonstrated that the new taxon is not subordinate to any other of these hepialoid clades. Its relationships are briefly discussed, but its exact affinities await further studies of hepialoid phylogeny. The term 'primitive Hepialidae' is here applied to four genera: Fraus Walker, Gazoryctra Hübner, Antihepialus Janse and Afrotheora. We use 'Hepialidae sensu stricto' to refer to the remaining genera of the Hepialidae sensulato (i.e. the Hepialidae of authors) until the phylogeny of the Hepialoidea is better understood. This does not indicate that the primitive Hepialidae are monophyletic while the Hepialidae sensu stricto undoubtedly are.

Joyeux & Baer, in 1935, recognized a new genus when they described Pseudoporrorchis houdemeri, a new species of Acanthocephala taken from the intestine of Centropus sinensis intermedius at Tonkin, Indo-China. They reviewed the literature and assigned four additional species to this genus as follows: Echinorhynchus rotundatus von Linstow, 1897; E. centropi Porta, 1910; E. bulbocaudatus Southwell & Macfie, 1925; and E. centropusi Tubangui, 1933. These same authors presented a tabular comparison of the five species, based upon all of the usual morphological details utilized in formulating specific descriptions. Morphologically the five species show close conformity in all essential features. In their host relations they are equally uniform in that each species utilizes some species of the avian genus Centropus as its definitive host. In the present paper a sixth species of this genus is described in which the same adherence to general morphological pattern is observed, although the definitive hosts are mammals instead of the customary bird hosts.

Plate homologies are identified and discussed in primitive representatives of cornute and mitrate stylophorans. Comparative morphological analysis suggests that: 1) Lagynocystida are digital-bearing mitrates; 2) Peltocystida are glossal-bearing mitrates; 3) in Mitrocystitida, glossal and digital are incorporated into a closed marginal thecal frame or modified into articulated posterior spines (Anomalocystitidae); 4)Ovocarpus? circularisis synonymized withO. moncereti; 5)Chauvelia discoidalisandMitrocystites riadanensisare both assigned to the genusAspidocarpus; 6)Mitrocystella barrandeiis assigned to the new genusPromitrocystites.The original reconstruction ofVizcainocarpus dentigerproposed by Ruta, (1997a) is modified, as a result of the identification of two additional plates in the posterior portion of the theca. The new speciesVizcainocarpus rutaifrom the Tremadoc (Lower Ordovician) of Shropshire (England) is described and represents the oldest record of mitrocystitidan mitrates.V. rutaidiffers fromV. dentigerin the relatively broader size of its zygal and marginals and in the presence, on the lower thecal surface, of a peripheral fringe of fibrillar stereom. A cladistic analysis of selected stylophoran taxa based on the proposed plate homologies indicates that: 1) cornutes and mitrates are sister-groups, both deriving from aCeratocystis-like ancestor; 2) Peltocystida and Mitrocystitida are sister-groups; 3) Lagynocystida is sister-group of (Peltocystida + Mitrocystitida); 4)Lobocarpusis not a cornute but a primitive Cambrian mitrate belonging either to the stem-group of Mitrocystitida or to the stem-group of (Peltocystida + Mitrocystitida); 5) Anomalocystitidae represents a family of the suborder Mitrocystitida.

Paracymbiomma gen. nov. is proposed to include six new species from Brazil: P. angelim sp. nov. (♂ ♀) from São Paulo, P. carajas sp. nov. (♂ ♀), P. bocaina sp. nov. (♂ ♀) and P. caecus sp. nov. (♂ ♀) from Pará, P. doisirmaos sp. nov. (♂) from Pernambuco and P. pauferrense sp. nov. (♂) from Paraíba. The genus is included in Theuminae by having the sternum with posterior region without rebordered margins, strongly protruding between coxae IV and with numerous long and erect setae, and by the vulva with highly convoluted ducts. It can be distinguished from the other members of the subfamily by the male palp with paracymbium, single RTA, bulb with sclerotized conductor and partly sclerotized median apophysis, and by the female epigyne with posteromedian atrium and sclerotized margin, and vulva with copulatory ducts long, strongly convoluted laterally with proximal part (closest to copulatory openings) translucent. Paracymbiomma carajas sp. nov., P. bocaina sp. nov. and P. caecus sp. nov. occur exclusively in ferruginous caves. We provide a discussion on specializations and adaptations of Paracymbiomma gen. nov. and other species of Prodidomidae to the subterranean environment.
