A new nemacheilid loach, Schistura obliquofascia, is described from Kalsa, a stream near Chanfi, tributary of Gola River,Ganga basin in Uttarakhand, India. The new species is readily distinguished from congeners by the following combinationof characters: 12–14 oblique olivaceous dark bars on the body and three rows of black spots on the dorsal fin; lateral linecomplete with 104–112 pores, dorsal fin with 3–4 simple and 8½ branched rays; 8+8 branched rays in caudal fin; dorsaladipose crest prominent; males lacking suborbital flap; and 10–11 pores in preoperculo-mandibular canal. The sequence of the cytochrome b gene of length 307 base pairs was used for molecular characterization of the species.

A New Species

A new species sandperch, Parapercis altipinnis, is described based on the holotype collected from Cebu, the Philippines at 55–65 m by SCUBA. The new species belongs to the P. cylindrica complex and can be distinguished by an extremely high first dorsal fin, the first spine slightly longer than the head; 3 predorsal scales; 42 or 43 lateral-line scales; teeth present on vomer and palatines. The body is reddish dorsally and blackish ventrally, with 5 large brownish saddles alternating with white bands on dorsal surface; scattered dots on top of head, first dorsal fin and dorsal surface; first dorsal fin milky white with 5 black marks on anterior margin; a black broad band below eye; cheek and throat blackish red surrounding by white color; row of 10 short white bars along the lateral side of body axis; row of 9 deep red to blackish bars on lower half of lateral side of body; base of pelvic fin and lower margin of caudal fin blackish; rows of black spots on soft dorsal fin. A key to the species of the complex is provided.

Morphological And Molecular Characterization

Buzionema lutgardae n. sp. (Nematoda: Oxyuridomorpha: Thelastomatidae) is described from the cockroach Byrsotria sp. (Blattaria: Blaberidae), endemic to Cuba. Females of B. lutgardae n. sp. are shorter than those of B. validum Kloss, 1966 (1600–2150 µm vs. 3131–3378 µm), but the oesophagus is comparatively longer (b = 2.96–3.77 vs. 4.65–4.87). The lateral alae of the new species extend from ca. the midpoint of the cylindrical part of the procorpus to the level of the anus in contrast to the base of the basal bulb to the level of the anus in B. validum. The males of B. lutgardae n. sp. are shorter than those of B. validum (780–940 µm vs. 1177–1423 µm) and their lateral alae end at some distance before the cloaca instead the level of the cloaca in B. validum. The phylogeny of B. lutgardae n. sp. is inferred by the D2-D3 domains of the 28S rDNA. B. lutgardae n. sp. and B. validum form a monophyletic clade with strong nodal support, as sister-group of the genus Leidynema Schwenck in Travassos, 1929.

Trichotylenchus gorganiensis n. sp. is described and illustrated based on morphological and morphometric data. The new species is characterized by its 760–1073 µm long body, conoid-rounded lip region continuous with the body contour and bearing 5–7 fine striae, 22.0–24.5 µm long stylet, basal pharyngeal bulb offset or slightly overlapping intestine, post-anal sac extending 50–73 % of the tail region, and cylindrical or subclavate tail with a striated terminus. Differences of the new species from the closely related species T. astriatus, T. astriatoides, T. changlingensis and T. papyrus are discussed. Photomicrographs and several taxonomic notes on 13 other species of Telotylenchinae, collected from Iran, are provided.

A New Species

To date the genus Diploplastron comprised only one species of ophryoscolecid ciliate, Diploplastron affine, which is characterized by having two retractable ciliary zones in the anterior end of the body, two slender and juxtaposed skeletal plates on the right side, a rod shape macronucleus, and two contractile vacuoles. During study on the characterization of rumen ciliate community composition in Brazilian domestic sheep, we observed ciliates with atypical morphology but with diagnostic features of genus Diploplastron. This study describes Diploplastron dehorityi, a new species of ophryoscolecid ciliate, that differs from D. affine, primarily, in the morphology of skeletal plates, morphology of nuclear apparatus and body shape. In addition to the similarities between the new species and congener species, D. dehorityi has some morphological similarities to species of genus Eremoplastron.

Adaptive Value

A new Corydoras is described from the Blanco and Ucayali river basins in Peru. The new species can be distinguished from its congeners by having the following features: (I) posterior margin of dorsal-fin spine with laminar serrations directed towards the origin of the spine; (II) a long, wide, arched, and continuous black stripe, which runs parallel to the dorsal profile of the body, extending at least from the region below anterior origin of dorsal fin to the anterior half of the ventral caudal-fin lobe; (III) a black stripe transversally crossing the eye, forming the typical mask-like blotch; mask clearly not fused to arched stripe in most specimens; some specimens with mask separated from arched stripe by a thin line around the suture between neurocranium (in the region composed by the posteroventral margin of parieto-supraoccipital plus the posterodorsal margin of the compound pterotic) and first dorsolateral body plate; (IV) posterior margin of pectoral-fin spine with laminar serrations directed towards the origin of the spine; (V) pointed snout, presenting a long mesethmoid, with anterior tip larger than 50% of the entire length of the bone; and (V) ventral surface of trunk covered by small, non-coalescent platelets. A discussion on the possible positive adaptive value of the arc-striped color pattern is also provided.
