A New Species

During a taxonomic study of parasites of freshwater fishes, three new gravid female nematodes of the genus Rhabdochona were recovered from the intestine of a freshwater fish, Botia dario caught from Jiri River. Detail study revealed the specimen as a medium-sized nematode, tapering at both ends with finely striated cuticle, 14 anterior teeth in the funnel-shaped prostome, vulva post-equatorially open, vagina muscular, posteriorly directed with an ovejector, eggs oval, thinshelled and embryonated, tail tip conoidly pointed. Thus, the present species is assigned to the genus Rhabdochona. Prevalence and intensity of infection is 20% (1/5) and 3(3/1) parasite per host, respectively. Comparing the relative characteristics of the two conspecies, the present species closely resembles Rhabdochona (Rhabdochona) acuminata. It differs in a few aspects such as the longer oesophagus, more anteriorly located excretory pore, longer vagina, thin-shelled eggs but smooth-shelled eggs in R.(R) acuminata, conoidly pointed tail tip but bluntly ended in R. (R.) acuminata. Based on these distinguishing characters the present species is described as a new species giving the name Rhabdochona (Rhabdochona) jiribamensis n. sp.

A New Species

AbstractA new species of entomopathogenic nematode, Steinernema phyllophagae n. sp., was isolated from a white grub (Phyllophaga sp.) in a live oak (Quercus virginiana) nursery. The new species is characterised by morphometrics of the infective Sjuvenile (IJ) with body length 1289 (1133-1395) μm, distance from anterior end to the excretory pore 99 (84-120) μm, tail 89 (77-109) μm, ratio a = 31 (27.6-35.5), H% = 57 (51-60) and E% = 110 (70-139). The pattern of the lateral field of IJ of the new species is 2, 5, 6, 8, 6, 2. The male of the first generation can be recognised by the length and shape of the spicule and gubernaculum, position of the excretory pore, D% = 75 (68-80), and GS% = 71 (61-77). The female can be recognised by the vulva having low epiptygma and by the presence of several papilla-like structures near the tail tip. Steinernema phyllophagae n. sp. differs further from other species of Steinernema by characteristics of ITS and D2D3 regions of rDNA.

Lateral alae absent, stoma short with four thickening cuticle like teeth, excretory pore posterior situated at the beginning of the intestine, V = 67 %, eggs oval with smooth shell, male without spicule, and genital papillae arranged with one pair of preanal papillae and one pair of postanal papillae.

This work deals with haplosclerid sponges off the coast of Maranhão State, northeastern coast of Brazilian shelf (southwestern Atlantic). A new species is described, Haliclona (Halichoclona) lernerae. Four species are recorded for the first time for the Brazilian coast: Amphimedon caribica (Pulitzer-Finali, 1986); Niphates lutea Lehnert & Van Soest, 1999; Neopetrosia subtriangularis (Duchassaing, 1850) and Petrosia (Petrosia) weinbergi Van Soest, 1980. Three species were recollected from the southwestern Atlantic and have their geographic distribution extended on the Brazilian coast: Callyspongia (Cladochalina) vaginalis (Duchassaing & Michelotti, 1864), Oceanapia bartschi (De Laubenfels, 1934) and Xestospongia muta (Schmidt, 1870). Two species were collected for the first time from the Maranhão State Coast: Niphates erecta Duchassaing & Michelotti, 1864 and Neopetrosia proxima (Duchassaing & Michelotti, 1864). A taxonomic study of those samples is given, including description, illustrations and geographic distribution.

A New Species

A new species of kathlaniid nematode, Megalobatrachonema waldeni, from the intestine of the northwestern salamander, Ambystoma gracile, in British Columbia is described. The new species is placed in the subgenus Megalobatrachonema (Chabaudgolvania) as it lacks valves in the oesophageal bulb. Megalobatrachonema waldeni differs from the two other members of this subgenus, M. elongatum (Baird, 1958) and M. terdentatum (Linstow, 1890), in having large cervical alae and distinctly separate lips, and in lacking hypodermal lip peduncles and a pseudosucker. Megalobatrachonema waldeni has simpler onchia, smaller spicules, and a more prominent swelling at the base of the oesophageal corpus than M. elongatum, and differs from M. terdentatum by its distinct corpus swelling, more anterior excretory pore, fewer caudal papillae, and longer tail.

Antennal Scale

We provide a detailed description, including illustrations, of a new species of mysid belonging to the genus Idiomysis W. M. Tattersall, 1922 from Pulau Bum Bum, Sabah, Malaysia. The presence of two segments of antennal scale, a shorter endopod of uropod than the exopod and a pair of minute spines at the apex of the telson distinguishes Idiomysis bumbumiensis sp. nov. from all other species in the genus. The present species is the seventh member of the genus Idiomysis and it is the first described in Southeast Asia. It is also the third species of tribe Anisomysini discovered in Malaysian waters. We include an updated dichotomous key of all Idiomysis species.

Wax Moth

The greater wax moth, Galleria mellonella Linnaeus, is well known as a pest of honey bees and for the biodegradation of wax and polyethylene by their larvae. The genus Galleria has long been considered monotypic and found worldwide. A taxonomic study of the genus Galleria is presented based on morphological and molecular characters (COI, CAD, wg). A new species (Galleria similis Roh & Song, sp. nov.) is recognized on the Korean peninsula. The new species is superficially similar to G. mellonella but they can be separated by the structures of hindwing venation and male genitalia. Habitus photographs and illustrations of diagnostic characters are provided.

Dorsal Tubercle

We report the discovery of a new species of the genus Pycnogonum Brünnich, 1764 found in the shallow waters of Green Island, Taiwan. Pycnogonum (Nulloviger) granulatum sp. nov. is characterized by the presence of the granular integument, a dorsal tubercle on the proboscis, the transverse ridges on the dorsal surface of the trunk, and the spines on the ventral surface of the tibia, tarsus, and propodus having cleft tips. Because the male gonopores are present and ovigers are absent, the present species belongs to the subgenus Nulloviger. The present species has been compared with P. (N.) moolenbeeki Stock, 1992, P. (N.) lobipes Stock, 1991, P. (N.) tuberculatum Clark, 1963, P. nodulosum Döhrn, 1881, and P. spatium Takahashi, Dick & Mawatari, 2007. Among the congeners, P. spatium is geographically the closest congener, of which type locality is Amami Island, Japan. The holotype of P. spatium was loaned from Hokkaido University Museum (ICHUM) and re–examined. To determine the exact gender of the holotype of P. spatium, additional investigations of the coxal pellicula and gonopores are required.

Integrative taxonomy tests the validity of taxa using methods additional to traditional morphology. The existence of two different morphotypes in specimens identified as Chrysotoxum vernale Loew (Diptera: Syrphidae) prompted their taxonomic study using an integrative approach that included morphology, wing and male-surstylus geometric morphometrics, genetic and ecological analyses. As a result, a new species is recognised, Chrysotoxum montanum Nedeljković & Vujić sp. nov., and C. vernale is re-defined. A lectotype and paralectotypes are designated for C. vernale to stabilize this concept. An additional species, Chrysotoxum orthostylum Vujić sp. nov., with distinctive male genitalia is also described. The three species share an antenna with the basoflagellomere shorter than the scape plus pedicel and terga with yellow fasciae not reaching the lateral margins. This study confirms the value of integrative approach for resolving species boundaries.
