    Nilus decoratus (Patel & Reddy 1990) comb. nov. Fig. 18: 3 Pisaura decorata Patel & Reddy 1990: 37, figs 1 a–d (description of female; holotype, female, and 1 female paratype from India, Guntur District, Valiveru, T.S. Reddy leg. 11 XII. 1986, NZSI, not examined as not available from the NZSI). Note. Based on the female copulatory organ and the characteristic dorsal colour pattern of the body (Patel & Reddy 1990: figs 1 a–d), this species clearly belongs to Nilus, as defined in this paper. The species seems to be close to N. paralbocinctus comb. nov. (cf. Jäger 2007: figs 44–46; sub Thalassius).Published as part of Jäger, Peter, 2011, Revision of the spider genera Nilus O.

    Andhracoides Wilson & Reddy, 2011, gen. nov.

    No full text
    Andhracoides gen. nov. Type species. Andhracoides shabuddin, sp. nov., here designated. Currently monotypic. Etymology. The prefix of the generic name, “Andhra” alludes to the Andhra Pradesh State in peninsular India, where the new genus has been found. The Latin suffix for likeness “oides”, an adjective with one termination, with “c” retained, is taken from the hypsimetopid genus name Phreatoicoides Sayce, 1900. The gender of Andhracoides is considered masculine. Diagnosis. Head. Frontal process above antennula (Fig. 3 A; dorsal margin of antennal notch) not curved. Pereon pereonite 1 dorsal margin in lateral view shorter than on pereonite 2 (Fig. 2 A). Pereonites 2–7 in dorsal view anteriorly longer than wide, decreasing posteriorly to wider than long. Coxal articulation to pereonites 2–4 nearly fused, 5–7 free. Pleotelson shallow (lateral fields sloping), lateral margin in dorsal view linear, broadening posteriorly (Figs 2 D, 9 A), dorsal surface in lateral view weakly curving, length substantially greater than width of uropodal insertion, lateral margin with fine setae only; posterolateral margin in lateral view uninterrupted, without distinct inflection differentiating apex, crenate, with 4 teeth, teeth rounded in cross-section (Figs 2 D, 9 D, G); posterior apex in dorsal view projecting posteriorly (not indented), dorsal margin of ventral anal ring projecting posteriorly (Fig. 9 C); dorsal surface without setose tubercles. Antennula and Antenna elongate with numerous flagellar articles. Antennular distal articles (Fig. 3 D) in cross-section circular; terminal article tubular, shorter than penultimate article; penultimate article not distinctly longer than other articles, width approximately subequal to antepenultimate article width. Antenna article 1 absent, article 5 longer than article 4, article 6 subequal to articles 4 and 5 combined (Fig. 3 C, E). Mandible. Palp article 3 medial surface naked (Fig. 4 A). Right lacinia mobilis with two dentate plates (smaller plate on anterior surface of larger plate) (Fig. 4 E). Spine rows with bifurcate spines, forming strongly convex arc in ventral view, protruding medially, basal insertions curving dorsally to posteriorly (Fig. 9 B– D). Molar process stout, heavily keratinised; complex setulate spines forming posterior row (Fig. 9 D). Pereopods. Pereopod I not sexually dimorphic, male and female pereopods similar; dactylus without distal accessory spines (Fig. 6 A–B); propodus without developed palm, margin convex to straight; without spines or rugose cuticular pad, cuticular fringe weakly developed; with only stout conical simple setae; merus distodorsal margin in cross-section shelf-like and U-shaped. Pereopods II–III (Fig. 6 C–D) dactylus shorter than propodus, with 1 distal accessory claw and no additional distal spines; propodus without articular plate on posterior side of limb. Pereopods II–IV (Fig. 6 C–E) basis lateral face ridge absent; ischium dorsal margin with simple setae, none robust. In male. Pereopod IV simple (not prehensile); propodus articular plate on posterior side of limb absent, basis dorsal ridge in cross-section angular and produced but not forming distinct plate. Pereopods V–VII (Fig. 7 A–B) dactylus with accessory claw ventral to primary claw; propodus articular plate on posterior side of limb absent; basis dorsal ridge angular in cross-section, not distinctly separated from basis shaft, with no large setae; lateral face ventral ridge present, setae absent. Pereopod VII ischium dorsal ridge without flange. Pleopods II–V (Fig. 8 B–F) exopod proximal article distolateral lobes shorter than distal article; exopod I lateral proximal lobe absent; endopods unilobed; without setae on margins; protopods medial margin coupling hooks absent. Pleopod II endopod appendix masculina (Figs 7 D–E, 8 C) geniculate, projecting laterally at base of appendage; basal musculature pronounced; proximal half of shaft broadly concave in ventral cross-section, not forming tube; distal tip acutely rounded, margins smooth; medial and lateral margins with stiff elongate setae. Uropod (Fig. 9 A–B, F–H) protopod margin with rounded denticles, dorsomedial ridge in dorsal view parallel to ventral margin, robustly curving to oppose pleotelson posterior margin, distomedial margin without spinose or robust setae. Endopod subequal to protopod length, straight dorsally, dorsal margin without robust setae or spines on dorsal margin. Remarks. This genus was originally thought to be part of the Nichollsia clade, but its pleotelson is sufficiently divergent that we have assigned it to a new genus in the family Hypsimetopidae Nicholls, 1943. Nichollsia has two similar described species N. kashiense Chopra & Tiwari, 1950 and N. menoni Tiwari, 1955 (although N. menoni would benefit from a revision). Moreover, we have found that the morphology described above applies to several undescribed species of Andhracoides gen. nov., found in Andhra Pradesh. The general pleotelson form of this genus, being flattened and broadening posteriorly with a well-developed terminal tip, is unlike any other hypsimetopid, which are either indented or at least transverse in dorsal view. Indeed, Andhracoides is unique among the Phreatoicidea in having a pleotelson that is not strongly vaulted, and therefore much more like other isopods in being rather flattened. We do not think, however, that this condition is basal because the pleotelson is similar to that seen in other Hypsimetopidae; for example, the postanal margin, which is present in other phreatoicideans and members of other families, is missing, as is typical for other members of this family. The terminal projection of Andhracoides is an extension of the anal ring and, like many other hypsimetopids, has dentition along the pleotelson posterior margin. Moreover, the males of Andhracoides species lack the enormously elongate uropodal exopods possessed by Nichollsia adult males. The exopod is reverse to this condition, with the male exopod being shorter than in the female (Fig. 9). A phylogenetic analysis of 65 phreatoicidean species and 421 characters (Wilson, in progress; data available on request; see Wilson, 2008 for details) finds that Andhracoides gen. nov., is sister to Nichollsia, as expected, and this group forms a clade with the two species of Pilbarophreatoicus Knott and Halse (one undescribed). Additionally, the hypsimetopid part of the cladogram is similar to that shown in Wilson (2008: fig. 4) but the position of Hyperoedesipus is moved to be sister to the Phreatoicoides – Hypsimetopus clade and the Pilbaran-Indian clade (Andhracoides, Nichollsia, Pilbarophreatoicus) emerges basally in the hypsimetopid clade. These results support the biogeographic relationship between India and Western Australia, if based on tectonic vicariance, suggests that these lineages are older than 135 million years (Wilson, 2008, table 2). In his introduction, Gupta (1989: 1) writes "In a personal communication to Dr. K. K.Tiwari, Prof. P. J. Sanjeeva Raj of Madras Christian College, Tarnbaram (Madras), informs that he has material of phreatoicid isopods from Andhra Pradesh (locality not revealed) in South India obtained during deep drilling operations for boring tube wells." This is almost certainly the first report of Andhracoides gen. nov. but further details have not appeared in the published literature. A conference abstract (Messana, 2004) mentions a species from Andhra Pradesh referred to Nichollsia; this species belongs to Andhracoides but is a different species with a heavily setose pleotelson. Its locality is reported to be Belum Cave (Messana, pers. comm.). Gupta (1989) mentions that Nichollsia has been recorded from a number of isolated localities in Uttar Pradesh and Bihar in the Gangetic Plains. These two genera appear to be isolated by major river systems in these two states.Published as part of Wilson, George D.

    Atopobathynella operculata sp. n. (Figs 1–4) Type locality and material examined. The River Godavari at Rajahmundry town (16 o 9 ’ N 81 o 47 ’ E), South India. The sampling site is located almost in the middle of the river basin wherefrom sand is being regularly mined and transported ashore. Here the riverbed has a deposit of fine sand and detritus particles, but with little or no clay, and is devoid of any macrophytic vegetation. Tidal influence from the nearby Bay of Bengal is non-existent, hence freshwater conditions prevail throughout the year. Holotype female (dissected and mounted on 4 slides, catalogue no. SMF 32211). Allotype male (undissected, catalogue no. SMF 32212). Female paratype 1 (undissected, catalogue no. SMF 32212). Female paratype 2 (dissected on one slide, catalogue no. SMF 32213). Female paratype 3 (undissected, catalogue no. SMF 32214). Male paratype (dissected on one slide, catalogue no. SMF 32215). All are kept in the collection of the Deutsches Zentrum für Marine Biodiversitätsforschung (DZMB) at Wilhelmshaven (Germany), being a department of the Senckenberg Museum und Forschungsinstitut, Frankfurt (SMF). Leg. Y. Ranga Reddy, 24 December 2002. Description of adult female. Total body length of holotype 1.41 mm, of paratypes 1.34–1.56 mm. Body elongated, almost cyclindrical, segments progressively widening and lengthening towards posterior end. All body segments including head with numerous perforations. Head only about 16 % longer than wide. Anal operculum massive, plate-like, somewhat subtriangular in outline, producing backwards and almost reaching the end of caudal furca (Fig. 1 A, B). Pleotelson with 1 seta on either side; seta smooth and much shorter than caudal furca.

Third segment with 1 long seta on outer distal margin, 1 dorsal plumose seta at distal outer corner; 2 short setae, 1 dorsal and 1 ventral, near distal inner corner. First segment of inner flagellum with a group of 3 unequal dorsal setae in the distal half (these setae seem to be the rest of the reduced and fused outer flagellum), 1 ventral plumose seta below apophysis; apophysis distinct but slender, reaching proximal fourth of next segment, with 1 apical and 1 ventral, subapical plumose setae. Second segment of inner flagellum with a group of 1 simple seta and 3 aesthetascs, which are longer than next segment, at distal outer corner; 1 long apical and 1 short ventral setae at distal inner angle. Terminal segment slenderest, with 4 setae and 3 aesthetascs. Antenna (Fig. 2 B): small, 1 -segmented, only slightly dilated distally, with 2 terminal unequal plumose setae and 1 short, subterminal, simple seta; lateral seta absent. Labrum (Fig. 2 C): flat, symmetrical in ventral view and characteristic in shape. Free margin straight, bearing 2 small median teeth, flanked on either side by 4 acuminate curved teeth, gradually increasing in size laterally, and with 1 smaller somewhat blunt tooth on either side; tubular pore with long, thick-walled, proximally dilated tube, occurring ventrally on either side at base of lateral main tooth. Also, fine spinules, in rows, discernible on ventral surface, as illustrated. Mandible (Fig. 2 D–G): distal part of pars incisiva with 3 teeth, proximal tooth small; all teeth pointed in lateral view (Fig. 2 D–F), but blunt in frontal view (Fig. 2 G). Pars molaris (“Borstenlobus”) articulate, consisting of 5 claws; distal one defined at base, strongly developed into plate-like structure (Fig. 2 D, E) (almost cylindrical in a different view as in Fig. 2 F), apical margin concave and finely denticulate; 2 additional denticles also occurring below denticulate margin (Fig. 2 E), 3 spinules seen at base of pars molaris on distal margin. Palp 1 -segmented, only slightly longer than wide, bearing a long terminal seta. Maxillule (Fig. 2 H): with 2 endites. Proximal endite small, subquadrate, twice as long as wide, carrying 2 unequal, serrulate, claw-like spines, and 1 tiny spinule; also, a simple, triangular lobe lying at base of endite. Distal endite straight, slender, 2.4 times as long as wide, armed with 3 terminal claws of similar size, 2 subterminal claws, all claws with serrulate inner margin, and 3 subterminal setae on distal outer margin. Maxilla (Fig. 2 I): 4 -segmented, second and third segments half fused, with 2, (4, 12), and 1 setae, respectively; distalmost segment tiny. Thoracopods I–VII (Fig. 3 A–C): well developed, length gradually increasing from pairs I–III, last 4 pairs almost similar in size; thoracopods II–VII with 1 -segmented epipod each. Coxa with distinct, pointed projection at distal inner border; basis of thoracopods II–VI alone with inner marginal seta. Exopod 1 -segmented, with 2 very unequal terminal setae and 1 short subterminal seta on ventral side; subterminal seta absent on thoracopod I alone. Endopod 4 -segmented. Setal formulae: Th. I, 1 +0/0+ 1 / 1 +0/ 2 (0); Th. II–IV, 0+0/0+ 1 /0+ 1 / 1 (0); Th. V–VII, 0+0/0+ 1 /0+0/ 1 (0). Thoracopod VIII (Fig. 1 C): minute, sharply pointed, denticle-like structure. Pleopod 1 (Fig. 1 C): represented by 1 strong, plumose seta. Uropod (Fig. 1 A–B): sympod slender, 4.4 times as long as wide, bearing 4 spines in a row on distal inner margin and 1 short, simple seta on dorso-lateral surface almost opposite to spine row; distalmost spine stout, straight, 31 % longer than other spines, which are acutely pointed and almost equal in size. Exopod cylindrical, nearly 6 times as long as wide, measuring 42 % of sympod length and bearing 2 apical, unequal setae, outer seta spiniform, unipinnate and less than half the length of inner, bipinnate seta. Endopod sickle-shaped, reaching 62 % of sympod length, lateral margins smooth, but a longitudinal of fine spinules at about the middle of proximal part, in lateral view; a single long, plumose seta at about midlength of outer margin. Description of adult male (Fig. 4 A–C). Total body length of allotype 1.52 mm, of paratype 1.46 mm. Body and all appendages except antennule and thoracopod VIII as in female. Antennule (Fig. 4 A): same as in female except for antennal organ on second segment; second segment 1.5 times as long as wide, antennal organ seen as a massive protuberance at distal inner angle, tip rounded with an opening. Thoracopod VIII (Fig. 4 B–C) rather small so that the constituent parts are difficult to make out and interpret. Protopod massive but without prominent penial region. In latero-external view (Fig. 4 B) two structures are discernible, one with 2 and one without setae. In ventral view (Fig. 4 C) the structure with 2 setae is extended into a spoon-like projection and is interpreted here as a basexopod with a basipodal seta (the bigger one) and an exopodal seta (the smaller one). The other structure without setae can be seen in ventral view (Fig. 4 C) as a conical projection reaching the spoon-like projection of the basexopod. This structure is interpreted here as the external lobe. Where both meet, the internal and the dentate lobe also converge. Dentate lobe with a few denticles can be seen in latero-external view (Fig. 4 B). Comparison with other species will reveal whether the interpretation presented here is tenable. Intraspecific variation. The number of spines borne by the sympod of uropod is either 4 or 5. Etymology. The specific name refers to the prominent anal operculum (Latin adjective operculatus, operire = to close, cover); gender feminine. Ecology. At the type locality, the new species was found as strays in the surficial sediments of knee-deep waters of an exposed island at the middle of the river bed. It was greatly dominated by Habrobathynella. The fauna that co-occurred with the new species was diverse but not rich, and included the following: Bathynellacea: Habrobathynella schminkei Ranga Reddy, 2004, and Habrobathynella sp. Copepoda: Bryocyclops sp., Paracyclops sp., Parastenocaris curvispinus Enckell, 1970, Parastenocaris gayatri Ranga Reddy, 2001, Elaphoidella sp., Mesochra wolskii Jakubisiak, 1933, Nitocra?lacustris (Schmankevitsch, 1875), Folioquinpes chathamensis (G.O. Sars, 1905), and Phyllognathopus viguieri (Maupas, 1892). Cladocera: Macrothrix sp., chydorids. Other taxa were: unidentified oligochaetes, nematodes, mites, and insect larvae.Published as part of Reddy, Ranga, 2008, A new species of the genus Atopobathynella Schminke, 1973 (Crustacea, Syncarida, Bathynellacea) from the hyporheic zone of the River Godavari, South India, pp. 52-60 in Zootaxa 1829 on pages 53-58, DOI: 10.5281/zenodo.18316
