A new cosmocercid nematode species, Cosmocerca asansolensis sp. nov. (Ascaridida, Cosmocercidae) is described from an Indian bullfrog, Hoplobatrachus crassus (Jerdon, 1853), from Asansol town, Paschim Bardhaman district, West Bengal, India. This species is characterized by the presence of five pairs of plectanes supporting preanal papillae, absence of somatic papillae in females, and having one pair large postanal papillae, a single papilla on the upper lip of cloaca, a single papilla on the lower lip of cloaca and one pair adanal papillae in males and one pair postanal papillae in females. Spicules of the present species are equal, moderately sclerotized, knobbed and wide proximal end gradually tapering to a fine point distally. The gubernaculum is well sclerotized and Y-shaped. Cosmocerca asansolensis sp. nov. represents the 33rd species assigned to the genus, 8th from Oriental region and 6th species from India.

A new species of threadfin bream, Nemipterus flavomandibularis, from the Western Indian Ocean is described and figured. The new species appears most closely related to N. bipunctatus (Valenciennes), but differs principally in colour pattern: N. flavomandibularis is distinct from N. bipunctatus in having two yellow bands on the snout, the upper lip narrowly edged with yellow; and lower lip and chin beneath lip yellow, this colour extending as a narrow band posteriorly to lower margin of opercle. Also, in N. flavomandibularus the scale rows below the lateral line are more or less horizontal (versus distinctly ascending anteriorly in N. bipunctatus), and the maxillary reaches to between level of posterior nostril and anterior margin of eye (versus reaching to below the anterior half of the eye in N. bipunctatus).

Salvia huastecana is described and illustrated as a new species. It is known from the municipality of Xilitla, San Luis Potosí, Mexico. This taxon belongs to Salvia sect. Angulatae, is similar to S. albiflora and S. roscida but it can be distinguished by a higher number of flowers per verticillaster (9−12), longer caducous bracts with long caudate apex, hirsute calyx with erect trichomes and white corolla, sometimes with the upper lip and margins of the lateral lobes of the lower lip light blue stained. Photographs of living plants and the illustration of the new species are provided.

Utricularia julianae, a new species from the savannas near the Oyapock River, French Guiana, is here described and illustrated. The new species is most similar to U. tenuissima, from which it can be easily distinguished by the leaves and stolons apparently lacking (vs. leaves few and on the stolons, the stolons few or lacking, in U. tenuissima), traps ellipsoid, 0.3 mm long, with 4–5 capilliform appendages (vs. ovoid, 0.3–0.8 mm long, with 1 dorsal and 2 ventral slender appendages), corolla upper lip limb deeply bilobed (vs. broadly ovate to round), spur saccate, perpendicular to the lower lip (vs. spur narrowly cylindrical, parallel to the lower lip), among other characters. In addition, the capsules of U. julianae and U. tenuissima are unique within the genus, by being very narrowly ovoid, dehiscing by a single longitudinal slit, and with a placenta projecting outside the dehisced capsule. On the basis of their numerous morphological similarities and their peculiar capsule shape and dehiscence, the new species is tentatively placed within sect. Martinia, which P. Taylor described to accommodate U. tenuissima.

A new small-sized species of dicroglossid frog from West Bengal is described as Minervarya chilapata sp. nov. and compared to Minervarya sahyadris. It differs from all Fejervarya species by its smaller size, by the presence of a distinct white band on upper lip and by the presence of a rictal gland. The new species is separable from its congener in showing a more pointed snout, smaller tympanum and more developed webbing. Its advertisement call is described and compared to that of M. sahyadris. Generic allocation is discussed. In the Fejervarya lineage, a trend towards small-sized species may exist. The species allocated to Minervarya show an important morphological shift, presumably reflecting occupation of a different adaptive niche which might indicate generic distinctiveness.

Microphysogobio wulonghensis sp. nov. is described based on 15 specimens collected from the Wulonghe River in Laiyang County of Shandong Province in eastern China. The new species can be distinguished from all congeners by the combination of the following characteristics: upper lip with one row of well-developed and compressed triangular papillae; two lateral pads of lower lip well-developed, contacting each other behind medial pad; two-thirds of area between pectoral-fin origin and pelvic-fin origin scaleless.

Abstract Nematode species of the genus Contracaecum Railliet & Henry, 1912 have been reported around the world in many species of fish-eating birds and seals. Here, Contracaecum jorgei n. sp. is morphologically described using light and scanning electron microscopy for adults and fourth-stage larvae (L4) found in the bird Nannopterum brasilianus and third-stage larvae (L3) found in the freshwater fish Hoplias argentinensis, both from the province of Córdoba, Argentina. Additionally, sequences of cytochrome c oxidase subunit II were obtained from these specimens and molecular phylogenetic analysis was used to determine its relationships within the genus. The present species is distinguished from other species by the number and disposition of cephalic papillae; shape and size of the interlabia; length of the spicules; and number and arrangement of papillae in the posterior end of the male. Furthermore, in the molecular analyses, sequences obtained from adult L4 and L3 specimens of C. jorgei n. sp. were similar and grouped, forming an independent lineage, thus confirming it as a distinct species. Thus, morphological characteristics associated with molecular data support the proposal of a new species.

A new species of Salvia from the state of Puebla, Mexico, is described and illustrated: Salvia gavilanensis sp. nov., growing in oak forests and oak scrubs, located in the Biosphere Reserve of Tehuacán-Cuicatlán. The new taxon is morphologically similar to S. microphylla, but differs by the herbaceous habit (vs. suffrutescent or shrubby), the strigulose pubescence of the leaves (vs. puberulent to tomentulous), bracts with the margin irregularly denticulate and persistent until the beginning of the anthesis (vs. bracts with the margin entire and deciduous before the anthesis), papillae inside the corolla tube with bidentate apex (vs. papillae with trilobate apex), and the lower lip of the corolla shorter in length compared to the upper lip (vs. lower lip of the corolla longer than the upper lip). Additionally, a phylogenetic analysis based on molecular data (nuclear ITS and the plastid regions trnL-trnF and trnH-psbA) was conducted to explore the relationships of the new species. According to the results, the new species belongs to the Fulgentes clade, which is congruent with the morphology of the species. A key to distinguish Salvia gavilanensis from other species of the clade present in the reserve of Tehuacán-Cuicatlán is included.

Barbatula karabanowi, new species, is described from the upper Bulgan River drainage in Mongolia. It is most similar to B. dsapchynensis from the Zavhan River basin (Lake Valley, Mongolia). The new species is distinguished from this and all other species of Barbatula in Asia by a combination of characters, none of them unique: nostrils widely spaced; snout broad, ratio between maximum head width and width of snout at anterior nare 1.4–1.6; lips smooth, upper lip with a short incision; lower lip with short, well developed lateral lobes, mental lobes oval, lacking conical protrusions; scales absent or isolated scales present on the flank between dorsal- and caudal-fin bases; 42–44 vertebrae (usually 43); 75–88 lateral line pores on flank; paired fins with rounded tips; pigmentation pattern with densely set and partially fused irregularly shaped blotches and streaks. Barbatula karabanowi occurs in syntopy with B. cf. altayensis. It is distinguished from this species by having widely separated nares (vs. closely-set), details in the mouth structure, few or no scales (vs. squamation well developed), less vertebrae and lateral line pores (42–44 and 75–88 vs. 44–45 and 89–105, respectively), “non-muscular” cheeks in both sexes (vs. thickened, especially in the males) and details in colour pattern. These two species were found to prey on different food items and were the only fish taxa found in the studied part of the river.
