Abstract— Based on the investigations of the representatives of the genus Cottus from Middle Asia, the species status of C. spinulosus is supported, and its diagnostic characters are specified. The validity of С.jaxartensis is resumed and a degree of its distinction from C. gobio is evaluated. A comparative analysis of morphological characters of the C. nasalis holotype and С.jaxartensis specimens of the same body size shows identity of these species, and, thus, C.nasalis has been included in the synonymy of C.jaxartensis. A new species C. nudus sp. nova is described. The representatives of this species differ from other Asian species of the genus in the following characters: absence of bony spickles nd dermal tubercles on the skin of the head and trunk; elongated upper jaw terminated near the vertical through posterior margin of orbit; presence of teeth on palatine bones; short sensory canal on the trunk with 23 pores; monochrome light coloration of the fins; and widened distal ends of neural and/or hemal spines in seven caudal centra. A key for the identification of three Middle Asian species (C. spinulosus, C. jaxartensis, and C.nudus sp. nova) is given.

A New Species

Niphargus lorestanensis sp.nov., a new species from west of Iran, is described and illustrated based on the analysis of morphological characters. Previous studies supported new species status using the phylogenetic analyses based on CO1, 28srDNA and H3 data in Esmaeili-Rineh et al., 2015. This species can be distinguished from other Iranian species by the equal length of palpus to outer lobe in maxilla I, the presence of multiple supporting robust setae in palmar corner of gnathopods I–II, not reaching dactyli to posterior margin of propodi in gnathopods I to II and trapezoid shape of propodi in gnathopods I–II. The Iranian fauna of Niphargus is currently represented by 18 described species.

A New Species

Anchoviella juruasanga is described from the drainages of rios Negro, Madeira, Tapajós, Trombetas, Tocantins, and Jari, in the Amazon basin, Brazil. The new species is distinguished from its congeners by having a short upper jaw, with its posterior tip extending between the verticals through anterior and posterior margins of the pupil (vs. posterior tip of upper jaw extending beyond the vertical through posterior margin of the pupil). Anchoviella juruasanga is also distinct from other strictly freshwater Amazonian species of the genus by the distance from tip of snout to posterior end of upper jaw between 8 and 11% in standard length (vs. 14% or more in A. alleni, A. carrikeri, A. guianensis, and A. jamesi). The anal-fin origin slightly posterior to or at the vertical through the base of the last dorsal-fin ray further distinguishes the new species from A. alleni (anal-fin origin posterior to the vertical through the last anal-fin ray by at least 14% of head length) and A. jamesi (anal-fin origin anterior to the vertical through the last anal-fin ray). An identification key for the Amazonian species of Anchoviella, including marine and estuarine species known to occur in the lower portion of the basin, is presented.

The new anchovy Stolephorus babarani n. sp. is described on the basis of 26 specimens collected from Panay Island, central Philippines. The new species closely resembles Stolephorus bataviensis Hardenberg 1933 and Stolephorus baweanensis Hardenberg 1933, all these species having a long upper jaw (posterior tip extending beyond posterior margin of preopercle), and numerous dusky spots on the suborbital area (in adults), snout and lower jaw tip. However, the new species differs from S. bataviensis by usually having the posterior tip of the depressed pelvic fin not reaching to vertical through the dorsal-fin origin (vs. extending beyond vertical through dorsal-fin origin), a shorter head (23.9–25.5% of standard length vs. 25.3–28.0%), and a greater distance between the dorsal-fin origin and pectoral-fin insertion (D–P1; 133.9–151.8% of head length vs. 109.9–136.3%). Stolephorus babarani is distinguished from S. baweanensis by having a shorter snout (3.6–3.9% of standard length vs. 3.8–4.6%). Moreover, the new species can be distinguished from S. bataviensis and S. baweanensis by higher gill raker counts on the first and second gill arches (16–18 + 21–23 and 10–13 + 18–21, respectively, vs. 14–17 + 19–22 and 9–12 + 17–20 in S. bataviensis and 14–17 + 19–22 and 9–12 + 17–21 in S. baweanensis). Stolephorus babarani is separated by 5.3% and 10.7% mean p-distances in the mitochondrial COI from S. baweanensis and S. bataviensis, respectively.

A New Species

The identity of specimens belonging to the genus Euseius Wainstein, 1962 found on several trees in France is investigated. These specimens are morphologically close to Euseius stipulatus (Athias-Henriot, 1960) except for the shape of the spermatheca and the dorsal shield reticulation. The aim of the present study was to determine if these specimens belong to this latter species and if the shape of the spermatheca could be considered a reliable diagnostic character. Thirty-four characters, including idiosomal seta lengths, were measured and molecular tests (12S rDNA, COI mtDNA) were carried out. Although small, significant differences between populations of Euseius sp. were observed. The morphometric differences between E. stipulatus and Euseius sp. were very small except for the seta z2 and for the length of the ventrianal shield, as well as the length and form of the spermatheca. Molecular analyses support that Euseius sp. and E. stipulatus are two different species. Euseius sp. has been described as a new species to science in another publication under the name Euseius gallicus . Reliability of some morphological characters for species diagnosis is discussed.

A New Species

Species of the genus Hebius Thompson, 1913 with 17 or 19 dorsal scale rows at midbody and an overall dark venter are reviewed, including the two species previously known as Parahelicops annamensis Bourret, 1934 and Pararhabdophis chapaensis Bourret, 1934. Specimens with 17 scale rows are morphologically similar to Hebius venningi (Wall, 1910), which is here redefined based on external morphological characters such as scalation, and dorsal and ventral patterns. Consequently, Natrix nigriventer Wall, 1925 is resurrected from its synonymy with Hebius venningi, whereas Natrix taronensis Smith, 1940, previously considered a subspecies of H. venningi or a full species by some authors but without justification, is here confirmed to full species status. Another group of species, mostly similar in coloration and pattern to the H. venningi group but with 19 dorsal scale rows, includes H. modestus (Günther, 1875), H. deschauenseei (Taylor, 1934) and a new species which is described herein based on specimens from northern Vietnam, southern China and north-eastern Thailand due to distinct morphological differences. We also provide updated taxonomic accounts for the species of this group, including an identification key and distribution maps.

The genus Procerobaetis Kaltenbach & Gattolliat, 2020 is reported for the first time from Thailand, and Procerobaetis totuspinosussp. nov. is described as a new species based on larvae. It can be easily distinguished from other known Procerobaetis species by the presence of triangular spines at the posterior margin of tergites VI–IX. COI sequences were obtained from all known species. The genetic distances (Kimura 2-parameter) between the new species and the other species are between 20% and 23%. The morphological characters of the new species and its closely related species are discussed; larval key to all species of the genus Procerobaetis is also provided.

A new plataycephalid, Platycephalus orbitalis, is described on the basis of specimens collected in the Indian Ocean off the coast of Western Australia at depths of 50–144 m. The new species had been mistakenly identified as P. marmoratus, which is now known to be restricted to eastern Australia. Several morphological characters (e.g, 65–68 pored scales in lateral line, snout and interorbit naked, and caudal fin blackish with white posterior margin) can separate Platycephalus orbitalis sp. nov. and P. marmoratus from the other 14 congeners. In addition, Platycephalus orbitalis sp. nov. differs from P. marmoratus in having the margin of the interopercle scalloped, skinny sensory tubes on the infraorbitals, the preopercle well developed and mostly covering the cheek region, and the body and head lacking distinct large spots and bands dorsally.

A New Species

Species of the genus Garra from the Irrawaddy and Salween River basins in west Yunnan, China are difficult to identify and their taxonomy remains problematic. We conducted a systematic review of the genus using a combination of molecular and morphological approaches to address these issues and describe a new species, G. surgifrons. Phylogenetic analyses indicate that 15 species of Garra do not form a monophyletic group. Garra imberba and G. nujiangensis form a distinct clade that is not sister to the remaining species of Garra. According to the combination of morphological characters of the proboscis and rostrum, Garra from western Yunnan Province can be divided into 4 groups: (1) smooth snout; (2) unilobed proboscis; (3) bi-lobed proboscis; and (4) tri-lobed proboscis. The types of snout shapes in Garra are consistent with the topological structure of the phylogenetic tree. Garra surgifrons can be distinguished from all other congeners occurring in China and Southeast Asia by a combination of the following characters: presence of a transverse lobe and a tri-lobed proboscis; both dorsal and caudal fins without black markings; the proboscis short and broad, a roughly quadrate shape from the dorsal view with a poorly developed and slightly protuberant middle lobe, with the front tip not suspended from the lateral view and the width almost equal to the width of the lateral lobes; the posterior margin of mental adhesive disc extending close to or reaching the vertical through the central line of the eye and never reaching the posterior margin of the eye; two pairs of barbels; 16 circumpeduncular scales; and 32–34 lateral line scales.

A New Species

The new anchovy Encrasicholina sigma n. sp. is described on the basis of 20 specimens collected from Sulawesi, Indonesia. Although the new species can be distinguished from all other congeners except for Encrasicholina pseudoheteroloba (Hardenberg 1933) by having a long upper jaw reaching to posterior margin of preopercle, dorsal and anal fins with two unbranched rays, an exposed bony urohyal, and spine-like scutes on the abdomen, E. sigma is distinguished from E. pseudoheteroloba by lower total gill-raker counts on the first, second, third, and fourth gill arches, and on the posterior face of the third gill arch (37–42, 31–35, 18–23, 16–20, and 4–7, respectively vs. 45–55, 34–45, 22–29, 19–25, and 4–9 in E. pseudoheteroloba) and a longer head (25.2–27.0% of SL vs. 22.8–27.5%) and shorter anal-fin base (12.9–14.8% of SL vs. 13.8–18.7%).
