Arboreal Snakes

We conducted a taxonomic revision of the arboreal snakes of the Boiga ceylonensis-group, all inhabiting the Indian subcontinent. Based on 15 characters, recorded from more than 100 specimens, representing eight recognized taxa, we conducted a multivariate morphometric analysis to redefine the taxonomic boundaries. We provide redescriptions of the nominate taxa in this group based on re-examination of the name-bearing types. The types of B. ceylonensis, B. beddomei, B. barnesii, B. dightoni, B. nuchalis and B. andamanensis are redescribed, where appropriate lectotypes are selected, illustrated and their nomenclature, synonymy and distribution are discussed. Status of the nominate taxon Boiga ceylonensis dakhunensis Deraniyagala, 1955 is fixed as an objective junior synonym of Dipsas nuchalis Günther, 1875. An updated key to the species of this group is presented.

Two New Species

The Neotropical genus Himantigera James in James & McFadden, 1982, is revised. Two new species are described and illustrated—H. amauroptera nov. sp. (Costa Rica, Panama, Colombia), and H. xanthopoda nov. sp. (Mexico, Nicaragua, Costa Rica). Three species are transferred from Himantigera to Sargus Fabricius, 1798—S. dichrous (Schiner, 1868) comb. nov., S. flavoniger Lindner, 1928 comb. rev. and S. fulvithorax (Bigot, 1879) comb. nov. One species is transferred to Microchrysa Loew, 1855—M. splendens (Schiner, 1868) comb. nov. Himantigera jamesi Lindner, 1969 syn. nov. is proposed as a junior synonym of H. superba Lindner, 1949. The type species H. silvestris McFadden, 1982, as well as H. nigrifemorata Macquart, 1847 and H. superba Lindner, are herein redescribed and illustrated. Photographs of the type specimens of these three species are provided. Two unnamed species of Himantigera (sp. A and sp. B) are also described given that they have slight differences, but because we had only one specimen of each species, we did not officially describe them. This updates the total number of extant Himantigera from eight sensu Woodley (2001) to seven species. The species Merosargus apicalis Lindner, 1935, although never referred to the genus Himantigera or Himantoloba McFadden 1970, is also transferred to the genus Sargus. A key to all species of Himantigera and a map expanding geographical distribution of the genus are also presented, with the first records of the genus for Nicaragua, Colombia, Venezuela, Trinidad and Tobago, Ecuador and Bolivia.

Males And Females

Recent samplings of callianassid shrimp from various habitats, together with the study of type specimens, show that Cal-lianassa gravieri Nobili, 1905 is a junior synonym of Callianassa bouvieri Nobili, 1904. Callianassa maldivensis Borra-daile, 1904, which had been synonymised with the latter, is a separate species. Morphometric analysis of more than 250specimens of these shrimps, which are assigned here to the genus Paratrypaea Komai & Tachikawa, 2008, show that P.bouvieri males and females have unequal chelipeds, whereas P. maldivensis has males with unequal chelipeds and femaleswith equal chelipeds. In addition, both species differ by the presence/absence and size of a median spine on the posteriortelson border. Male P. bouvieri and P. maldivensis are superficially similar but can be differentiated based on numerouscharacters of the major chelipeds, which are illustrated here in detail. The two species occur in different habitats, P. bou-vieri in the intertidal, often near mangroves, P. maldivensis usually sublittoraly near patchy corals. The importance of size and sex when comparing callianassid species is discussed.

A taxonomic revision of Anostomoides is herein presented based on a comprehensive revision of specimens deposited in fish collections and the literature. The present revision proposes that A. laticeps is a junior synonym of A. atrianalis, while A. passionis is a junior synonym of Leporinus nattereri, and the latter is thus transferred to Anostomoides, forming the new combination Anostomoides nattereri. Principal Components Analysis (PCA) showed that examined specimens form two distinct morphotypes, corroborating the validity of both A. atrianalis and A. nattereri. Anostomoides nattereri is distinguished from A. atrianalis by having four branchiostegal rays (vs. three), three pores in infraorbital one (vs. four), 37–39 pored lateral-line scales (vs. 41–44), lower lip with rounded dermal papillae (vs. forming ridges), three dark  rounded midlateral blotches (vs. three or four vertically elongated blotches and/or a faded dark longitudinal stripe), dark lines between scale series on posterior half of body on specimens smaller than 150 mm SL (vs. dark lines absent), a greater body depth (27.6–36.2 % vs. 24.5–38.7% of SL) and smaller interorbital distance (34.4–53.8 % vs. 42.6–67.3 % of HL). Anostomoides nattereri is distributed across several tributaries of the Amazon and Orinoco rivers, whereas A. atrianalis is widespread throughout the Amazon, Orinoco, and Essequibo basins. The genus Anostomoides is currently diagnosed based on a combination of non-exclusive characters: upturned or slightly upturned mouth with four premaxillary teeth including symphyseal tooth bicuspid or with blunt cutting edge, remaining teeth slightly tricuspid (with medial cuspid distinctly larger); four dentary teeth, symphyseal tooth with truncate cutting edge (without cusps); second tooth with a single large cusp, and two lateral teeth with three or slightly more small cusps.

Oral Area

AbstractThe Holocystites Fauna is an enigmatic group of North American diploporitans that presents a rare window into unusual middle Silurian echinoderm communities. Multiple systematic revisions have subdivided holocystitids on the basis of presumed differences in oral area plating and respiratory structures. However, these differences were based on a fundamental misunderstanding of the homologous elements of the oral area and the taphonomic process; taphonomic disarticulation of the oral area formed the basis for the erection of Pentacystis and Osgoodicystis as separate genera, and Osgoodicystis is interpreted as the junior synonym of Pentacystis. Holocystitids show a conservative peristomial bordering plate pattern that is shared among all described genera. The peristome is bordered by seven interradially positioned oral plates as is typical for oral plate–bearing blastozoans. A second open circlet of facetal plates lies distal to the oral plates; five of these facetal plates bear facets for feeding appendages (lost on the A ambulacrum in some taxa), while two lateral facets (present in all taxa except Pustulocystis) do not. Holocystitid taxa show minor modifications to this basic peristomial bordering plate pattern. As thecal morphologies are highly variable within populations, taxonomic revision of holocystitids is based on modifications of the plating of the oral area.

The Afrotropical species described as Trachyphloeini Lacordaire, 1863 were examined and their taxonomic status is revised. Atrachyphloeus Voss, 1962 is proposed as a junior synonym of Phaylomerinthus Schoenherr, 1842, Cathormiocerus africanus Hoffmann, 1965 as a junior synonym of Tapinomorphus sylvicola Voss, 1962 and Trachyphloeus pustulifer Voss, 1959 as a junior synonym of Platycopes tuberculatus Marshall, 1906. Atrachyphloeus convergens Voss, 1962 is transferred to the genus Phaylomerinthus Schoenherr, 1842, Trachyphloeus hardenbergi Marshall, 1923 and T. notulatus Boheman, 1842 to Glyptosomus Schoenherr, 1847, Trachyphloeus nanus Fåhraeus, 1871 to Pentatrachyphloeus Voss, 1974, Trachyphloeus pustulifer Voss, 1959 to Platycopes Schoenherr, 1823 and Trachyphloeus setiger Fåhraeus, 1871 to Phaylomerinthus Schoenherr, 1842. “Trachyphloeosoma” brevicolle Voss, 1974, “Trachyphloeus” brevis Boheman, 1842, “T”. nodifrons Hoffmann, 1968 and “T”. squalidus Boheman, 1842 are provisionally left in their current genera, but new genera for them will be described in future papers. The genus Phaylomerinthus Schoenherr, 1842 has been redefined and redescribed. Lectotypes for the following species are designated (current names added in brackets where different): Cathormiocerus africanus Hoffmann, 1965 (Tapinomorphus sylvicola Voss, 1962), Trachyphloeus hardenbergi Marshall, 1923 (Glyptosomus hardenbergi (Marshall, 1923)), Trachyphloeus nanus Fåhraeus, 1871 (Pentatrachyphloeus nanus (Fåhraeus, 1871)), Trachyphloeus notulatus Boheman, 1842 (Glyptosomus notulatus (Boheman, 1842)), Trachyphloeus pustulifer Voss, 1959 (Platycopes tuberculatus (Marshall, 1906)), Trachyphloeus setiger Fåhraeus, 1871 (Phaylomerinthus setiger (Fåhraeus, 1871)), “Trachyphloeus” brevis Boheman in Schoenherr, 1842 and “Trachyphloeus” squalidus Boheman in Schoenherr, 1842. Two paralectotypes of Cathormiocerus africanus Hoffmann, 1965 from Tanzania are described as a new species, Tapinomorphus franzi sp. n. All type specimens are illustrated.

Holotypes of 19 species and non-type specimens preserved in the Sasa collection at The National Museum of Science, Tokyo, Japan, have been examined. Seventeen new synonyms are given, as follows: Paratrissocladius ogasaduodecimus Sasa et Suzuki, 1997 = Paraphaenocladius impensus (Walker, 1856); Bryophaenocladius togafelix Sasa et Okazawa, 1992, and B. toganitemus Sasa et Okazawa, 1992 = Pseudorthocladius togakileus Sasa et Okazawa, 1992; Bryophaenocladius togatenuis Sasa et Okazawa, 1992 of Smittia nudipennis (Goetghebuer, 1913); Chironomus daitoefeus Sasa et Suzuki, 2001 of C. circumdatus Kieffer, 1916; C. inaabeus Sasa, Kitami et Suzuki, 2001 = C. nippodorsalis Sasa, 1979; C. tokarabeceus Sasa et Suzuki, 1995 = C. okinawanus Hasegawa et Sasa, 1987; C. ginzanbeceus Sasa et Suzuki, 2001 = C. riparius Meigen, 1904; C. simantobeceus Sasa , Suzuki et Sakai, 1998 = C. claggi Tokunaga, 1964; C. echizensis Sasa, 1994 = C. yoshimatsui Martin et Sublette, 1972; Chironomus famiabeus Sasa, 1996, C. inabeceus Sasa, Kitami et Suzuki, 2001 and C. ginzanabeus Sasa et Suzuki, 2001 = Glyptotendipes biwasecundus Sasa et Kawai, 1987; Chironomus kagaensis Sasa, 1994 = Glyptotendipes tokunagai Sasa, 1979; Chironomus toyamabiceus Sasa, 1996 = Kiefferulus umbraticola Yamamoto, 1979; Microtendipes iriocedeus Sasa et Suzuki, 2000 of Polypedilum bingoparadoxum Kawai, Inoue et Imabayashi , 1998. The sufficient reason why Chironomus daitocedeus Sasa et Suzuki, 2001 should be treated as a junior synonym of C. javanus Kieffer, 1924 is shown. Two further species: Paratrissocladius sudagaicedeus Sasa et Tanaka, 2001 and Bryophaenocladius togatenellus Sasa et Okazawa, 1992 are transferred to Chaetocladius. Specimens from Okinawa, Miyako and Ishigaki Islands, originally reported as Rheocricotopus chalybeatus (Edwards, 1929) are identified as R. okifoveatus Sasa, 1990. A new species, Einfeldia sasai is described on the basis of specimens recorded from Minamidato Island, previously incorrectly determined as E. pagana.

The present study redescribes four species of Neanthes Kinberg, 1865 (Nereididae de Blainville, 1818) based on their type specimens collected from different worldwide localities: Neanthes chilkaensis (Southern, 1921) from India, N. galetae (Fauchald, 1977) from Panama, N. helenae (Kinberg, 1865) from St Helena Island, and N. mossambica (Day, 1957) from Mozambique. The morphology of the types was re-examined for the first time after the species were originally described, and incorporated the recent improvements in the standards and terminology for describing nereidid features. The arrangement of paragnaths on area VI stood out among the diagnostic features used to distinguish these four species. Neanthes chilkaensis and N. helenae are the unique nereidids bearing p-bar paragnaths on the area VI. Both species are also distinctive as the former species only exhibited p-bar paragnaths on the area VII–VIII and the latter ventrolateral projections on the apodous segment. Further examination revealed that N. nanciae (Day, 1949) from St Helena is a junior synonym of N. helenae. Moreover, N. galetae and N. mossambica are distinguishable from other species also by the development of dorsal cirri, neuropodial postchaetal lobe and ventral ligule, the presence/absence of merged paragnaths on area IV, paired oesophageal caeca, among other features. This study has further contributed to the morphological delimitation of the species in Neanthes as a first step towards revising the genus.

Abstract. INTRODUCTIONTrochamminoides elegans (Grzybowski) [= Trochammina elegans Grzybowski, 1898] is a familiar species that is commonly recorded from the Paleogene of the Carpathian flysch. However, during the course of work on a taxonomic revision of the Grzybowski Collection, it has become apparent that the name of this taxon is in actuality, invalid.The designation Trochammina elegans was first used by Rzehak (1887), but since the name only appeared in a table (without a description or illustration) the name is unavailable under Article 12 of the ICZN. Grzybowski (1898), who had received specimens from Rzehak, referred to this species as “Trochammina elegans Rzehak”, but the authorship of the species belongs to Grzybowski under Article 50 of the ICZN. Grzybowski (1898) described Trochammina elegans as follows: Test agglutinated, surface rough; circular in outline, spirally coiled in two and one-half to three whorls. Chambers spherical, increasing in size, numerous, with depressed sutures; there are thirteen to fifteen of them in the last whorl. Aperture at the lower edge of the last chamber, just above the rounded periphery. Diameter 1.3 mm.However, transferring the authorship of this species makes Trochammina elegans Grzybowski, 1898 a primary junior homonym of Trochammina elegans Egger, 1893 (Article 53c of the ICZN). As such, the name must be permanently rejected (Article 52a). Because no junior synonym exists, we propose the replacement name Trochamminoides grzybowskii Kaminski &amp; Geroch, nom. nov.SYSTEMATIC DESCRIPTIONSuborder:Textulariina Delage &amp; Herouard, 1896Genus: Trochamminaides Cushman, 1910Trochamminoides grzybowskii Kaminski &amp; Geroch, nom.nov. for Trochammina elegans. . .
