Seven new species ofCichlidogyrusPaperna, 1960 (Monogenea: Dactylogyridae) isolated from the gills of six cichlid host species belonging to four tribes and sampled from the Congolese coastline of Lake Tanganyika (LT) are described:Cichlidogyrus adkoningsisp. nov. fromCyphotilapia frontosa(tribe Cyphotilapiini);C. koblmuellerisp. nov. fromCardiopharynx schoutedeni(Ectodini);C. habluetzelisp. nov. fromC. schoutedeniandC. frontosa;C. antoinepariselleisp. nov. fromInterochromis loocki(Tropheini);C. masilyaisp. nov. fromPetrochromis orthognathus(Tropheini);C. salzburgerisp. nov. fromP. trewavasae, andC. sergemorandisp. nov. fromTylochromis polylepis(Tylochromini). This study represents the first parasitological examination of cyphotilapiine cichlid hosts. Representatives of the Tanganyikan ectodine, tropheine, and tylochromine cichlids previously sampled from various localities in the lake yielded nine, twelve, and two described species ofCichlidogyrus, respectively. The study further includes a morphological characterization of the male copulatory organ of six undescribed species ofCichlidogyrusfound on the gills of the tropheinesI. loockiandP. orthognathus,and on those ofCallochromis melanostigmaandXenotilapia flavipinnis(both Ectodini). Geographical variation in the monogenean fauna ofI. loockiwas observed. The most closely related cichlid species investigated in this study harbouredCichlidogyrusspp. exhibiting some similarities in their sclerotized structures. Thus, our paper provides additional evidence of the high species richness ofCichlidogyrusand the link with their hosts’s phylogenetic affinities in LT.

Twenty-six species of endogean beetles are recorded from the Marganai-Oridda-Valle del Leni area, belonging to six different families: Carabidae (Typhloreicheia holdhausi Magrini, Fancello & Casale, 2006, T. leoi pilosa Magrini & Fancello, 2007, T. tanit Leo, Magrini & Fancello, 2005), Leiodidae [Bathysciola damryi (Abeille de Perrin, 1881)], Staphylinidae [Eudesis aglena Reitter, 1882, E. minima Binaghi, 1948, Mayetia sp., Trimium amplipenne Reitter, 1908, Tychobythinus dentimanus (Reitter, 1884), Tychus sp., Pselaphostomus sp., Phloeocharis ichnusae Dodero, 1900, Octavius raymondi Saulcy, 1878, O. sardous Coiffait, 1965, four new species of Entomoculia, three new species of Leptotyphlus], Zopheridae (Langelandia reitteri Belon, 1882, Lyreus septemstriatus Fancello & Leo, 1991), Curculionidae (Torneuma sp.) and Raymondionymidae [Alaocyba carinulata Perris, 1869, Raymondiellus sardous sardous (Perris, 1869)]. One species (Langelandia reitteri) is W-Mediterranan, one is a Sardo-Corsican endemic (Tychobythinus dentimanus), the remaining 24 species are all Sardinian endemics and 16 of these are strictly localized within the study area or restricted to SW Sardinia. The following species of Staphylinidae Leptotyphlinae are described: Entomoculia villascemae sp. nov., E. carbonaria sp. nov., E. shardana sp. nov., E. melonii sp. nov., Leptotyphlus nardii sp. nov., L. minator sp. nov. and L. villacidrinus sp. nov.; all are easily distinguishable from their congeners by the structure of the male copulatory organ and female genital armature. The morphology of the copulatory organ in the newly described Leptotyphlus species indicates that the classical subgeneric categories used in Leptotyphlus are probably based on characters not reflecting a natural subdivision of the genus.

AbstractMolecular and morphological characterization of two species of Cucullanidae from freshwater fish in Brazil are provided, one of which represented an undescribed taxon. Cucullanus opisthoporus n. sp. was collected in Cichla melaniae from River Xingu, State of Pará, and in C. pinima from River Jamarí, State of Rondônia. Nematodes referable to Cucullanus grandistomis were collected in Oxydoras niger from River Xingu. The new species has an appendage in the tail tip, ventrally covered by small spines, which is an exclusive feature of Cucullanus tucunarensis. However, C. tucunarensis differs from C. opisthoporus n. sp. based upon the relative position of deirids and the excretory pore, which are more posterior from the oesophageal end in the new species. Observations of C. tucunarensis type specimens also revealed features that were wrongly or not reported in the original description. Type specimens of C. grandistomis were observed, although they were poorly preserved. After evaluation of newly collected specimens of C. grandistomis, features unreported in the original description were observed for the first time, including the presence of an intestinal caecum. Thus, C. grandistomis was transferred to Dichelyne. Sequences of the 18S and 28S rRNA genes revealed high genetic similarity between the specimens of C. opisthoporus n. sp. from the two different hosts as well as their genetic distance from Dichelyne grandistomis n. comb. Phylogenetic reconstructions using representatives of Cucullanidae suggested the artificiality of the current morphological system adopted to separate the genera, since most genera were not monophyletic, although the availability of genetic data is still fragmented.

Abstract In this study, we report the first records and morphological characterization of galls in a Cerrado area in western Bahia, Brazil. The data were collected monthly over two hours between March and September 2015. Fifteen gall morphotypes were found in twelve plant species distributed among seven families. The plant family with the greatest richness of galls was Fabaceae (n = 8). The following gall morphologies were found: globoid, lenticular, marginal leaf roll, conical, cylindrical, fusiform, spherical and pocket shaped. Cecidomyiidae induced globoid, lenticular, conical, fusiform, spherical and cylindrical morphotypes. In addition, species of microhymenoptera belonging to the Eulophidae, Eurytomidae and Encyrtidae families were found. Marginal leaf roll and pocket-shaped galls induced by Thysanoptera were also verified. Springtails were also identified as a successor. Undescribed species of Schizomyia and Lopesia were recorded in B. cupulata and Andira humilis, respectively.

AbstractCalydiscoides limae sp. nov. is described from the nemipterid Pentapodus aureofasciatus Russell, 2001 caught along the barrier reef off New Caledonia, South Pacific. The new species is characterised by its male copulatory organ, with a distal blade and a lateral spur, and its female sclerotised organ, with a sphere and a thin tube. Its lamellodiscs always have 7 concentric lamellae, with the 3 internal lamellae complete and the 4 peripheral lamellae progressively less and less complete; measurements of the angles occupied by the lamellae in numerous specimens showed that the lamellodisc structure shows little variation among individuals.

Morphological And Molecular Data

AbstractThe present study describes Demidospermus spirophallus n. sp. and Demidospermus prolixus n. sp. (Monogenea, Dactylogyridae) from the siluriform catfish Loricaria prolixa Isbrücker & Nijssen, 1978 (Siluriformes, Loricariidae) from the state of São Paulo, Brazil, supported by morphological and molecular data. In addition, notes on the circumscription of the genus with a redescription of Demisdospermus anus are presented. Demidospermus spirophallus n. sp. differed from other congeners mainly because of the morphology of the male copulatory organ (MCO), which exhibited 2½ counterclockwise rings, a tubular accessory piece with one bifurcated end and a weakly sclerotized vagina with sinistral opening. Demidospermus prolixus n. sp. presents a counterclockwise-coiled MCO with 1½ rings, an ovate base, a non-articulated groove-like accessory piece serving as an MCO guide, two different hook shapes, inconspicuous tegumental annulations, a non-sclerotized vagina with sinistral opening and the absence of eyes or accessory eyespots. The present study provides, for the first time, molecular characterization data using the partial ribosomal gene (28S) of two new species of Demidospermus from Brazil (D. spirophallus n. sp. and D. prolixus n. sp.), and Demidospermus anus from Loricariichthys platymetopon Isbrücker & Nijssen, 1979 collected in the Upper Paraná River floodplain, Brazil. Additionally, a revision of the species composition of this genus and others that occur in catfish is proposed to elucidate problems with their circumscription. The Brazilian species of Demidospermus clustered together as sister taxa among Neotropical dactylogyrids from siluriforms. The morphological characterization of D. spirophallus n. sp. and D. prolixus n. sp., and the molecular data of the three species in the present study will extend knowledge about this monogenean genus from the Neotropical region, and provide new information for future phylogeny studies.

The circumscription and morphological characterization of the deltocephaline tribe Acostemmini is revised based on dis-coveries of new and poorly known taxa from recent collections in Madagascar and from examination of the type speci-mens of Alocoelidia fulva Evans, Iturnoria insulana Evans, and Protonesis delegorguei Spinola. Alocoelidia Evans 1954,Caelidioides Signoret 1880, Iturnoria Evans 1954, and Protonesis Spinola 1850 were previously placed in Coelidiinaebut were later removed from the subfamily and until now have been unplaced to subfamily are placed here in Deltocepha-linae: Acostemmini, new placement. A new genus and species, Ikelibeloha cristata gen. n., sp. n., are described that havean unusually modified structure of the head and a large, crested pronotum. Molecular data (28S, Histone H3 genes) wereobtained for Ikelibeloha and Iturnoria, and analyzed with other members of Deltocephalinae. Results of the phylogeneticanalyses show strong support for the monophyletic clade ((Acostemma, Eryapus), (Ikelibeloha, Iturnoria)) and thus a re-lationship between previously described Acostemmini, Ikelibeloha, and Iturnoria has strong statistical support, and aclose relationship is inferred between these and the morphologically similar Alocoelidia, Caelidioides, and Protonesis.Two new species of Alocoelidia, A. maurae sp. n. and A. chasei sp. n. are described, and the genus is redescribed. Themale genitalia of Caelidioides tristis (Signoret), Iturnoria insulana, Alocoelidia fulva, and Acostemella rubra Evans areillustrated and described for the first time. The female genitalia of A. fulva, C. tristis and I. insulana are described and thefirst and second valvulae of C. tristis are illustrated. The habitus and face of Protonesis delegorguei are illustrated and thegenus is redescribed. The characters traditionally used to define Acostemmini are reviewed with notes on their known de-grees of variation, and characters that differentiate Acostemmini from the closely related tribe Stegelytrini are discussed.The type of Malagasiella minima Evans was also examined, and Malagasiella Evans, 1954 is considered a junior syn-onym of Doratulina Melichar, 1903 (Deltocephalinae: Stenometopiini), syn. n. giving the new combination Doratulina minima (Evans) comb. n.
