The Redeye Bass, Micropterus coosae, was described from the Mobile River basin, Chattahoochee, and Savannah rivers in Alabama and Georgia, USA, by Hubbs and Bailey (1940). At that time the authors recognized significant variation in the Black Warrior River population, and noted that with further study this form may be recognized as a separate taxon. An examination of variation in morphology and mitochondrial DNA supported this observation, and highlighted additional species-level variation, resulting in descriptions of a total of four new species: Micropterus cahabae, new sp., restricted to the Cahaba River system; Micropterus tallapoosae, new sp., restricted to the Tallapoosa River system; Micropterus warriorensis, new sp., from the Black Warrior River system; and Micropterus chattahoochae, new sp., from the Chattahoochee River system. Micropterus coosae is restricted to the Coosa River system. The new species differ from each other and from M. coosae by a combination of pigmentation and scale count characteristics, development of the tooth patch, and divergence within the ND2 gene. While two of these species are relatively common in upland streams within their ranges, M. warriorensis, M. cahabae and M. chattahoochae are uncommon and may warrant protection.

Pelvic Fin

Chaetostoma formosae sp. nov. is described from piedmont tributaries of the upper río Meta on the Cordillera Oriental in Colombia. The new species is distinguished from its congeners by the presence of an elongate unbranched anal-fin ray with two posterior dermal ridges in mature males, the presence of strongly recurved cheek odontodes, the presence of a parieto-supraoccipital dermal keel, the posterior margin of the pelvic-fin strongly projected and angulate in shape in mature males, and by details of coloration. The new species belongs to an informal monophyletic group herein called the Chaetostoma anale species group, along with two additional species, C. anale and C. jegui, from Colombia and Brazil respectively, based on an apomorphic modification of the anal fin in mature males.

The members of the genus Pelthydrus are small-sized aquatic beetles which belong to the water scavenger beetle family Hydrophilidae. At present the lineage includes 63 valid species mainly occurring in Asia, with 21 known from China (Bian et al. 2008, 2009; Hansen 1999; Schönmann 1995). One new species is described here, which belongs to the Pelthydrus sculpturatus species group, bringing the total number of species within the group to seven (Schönmann 1995). One additional species is reported from China for the first time. Specimens were collected from Yunnan Province and are deposited in IAECAS (Institute of Applied Ecology, Shenyang, Chinese Academy of Sciences).

Background and aims – During the past two decades, the subantarctic diatom flora has been the subject of several detailed taxonomic revisions, resulting in the description of a large number of new species. During a survey of the freshwater diatom flora of Macquarie Island (southern Pacific Ocean), an unknown Navicula species was observed showing resemblance to Navicula gottlandica. Populations of similar diatoms (previously reported as N. gottlandica) from Tasmania were also investigated. We here present a detailed morphological analysis of these diatoms, and compare it with the type material of N. gottlandica. Methods –Materials were analysed using Light and Scanning Electron Microscopy. Key results –The southern hemisphere populations represent two hitherto unknown taxa here described as Navicula bergstromiana and N. eileencoxiana. Important morphological differences include valve shape, stria density, shape of the central area, ultrastructure of the external central raphe endings, presence of a distinct internal accessory rib, and the relative width of the external longitudinal silica strips covering the valve face with respect to the longitudinal fissures separating these strips. While the new taxa show some affinity with the genus Haslea, the internal apical structure of the raphe, the external structure of the terminal raphe fissures and the central raphe endings (often with tooth-like protrusions, creating the impression of a satellite pore), and the apparent lack of the typical sandwich-type Haslea valve ultrastructure support the position of N. gottlandica and both new taxa within the genus Navicula. Conclusions – The description of two additional species with close similarities to N. gottlandica (i.e. possessing the typical longitudinal striae/silica strips and tooth-like protrusions in hooked central raphe endings) suggests that the N. gottlandica species group is more diverse than previously thought. The existence of closely similar Navicula species recently described from rivers in tropical South America but also from marine littoral samples in South and North America and China, raises intriguing questions about their phylogenetic relationships, ecology and biogeography.

A New Species

Squalius janae, sp. nov., is described from the upper Dragonja River system in the Adriatic Sea basin in Slovenia. The new species is distinguished from other members of the S. cephalus species group by a combination of the following characters: a long head, head length, 29−32% SL, always markedly exceeding body depth; a pointed conical snout; a slightly subterminal mouth, with a clearly projecting upper jaw; a long straight mouth cleft; lower-jaw length 39−45% HL, always greater than caudal-peduncle depth; a large eye, its diameter 19−25% HL; a large triangular 5 th infraorbital; a marked discontinuity between the dorsal profile of the head and body; usually 44−47 total lateral-line scales; usually 9½ branched anal-fin rays; usually 44 total vertebrae (24+20 and 25+19); a strong silvery tint in colouration; scales easily lost; iris, pectoral, pelvic and anal-fin pigmentation with yellow shades; flank scales margined by a few black pigment dots along their free margin and intense pigments on scale pockets, forming vertically elongate black spots.

Geometric Morphometric Analysis

Two new species of miniature silverside fishes are described from coastal habitats in the tropical Atlantic: Membras pygmaea sp. nov., from Brus Lagoon, Honduras, and M. procera sp. nov., from the Gulf of Urabá, Colombia. These new species belong to the martinica species-group within the genus Membras Bonaparte. The monophyletic martinica species-group (see below) contains four additional species, all coastal, marine that extend from the east coast of North America to São Paolo State, Brazil. Within the martinica species-group, all but M. martinica are miniature species, ranging from 41–60 mm SL. The smallest species, M. pygmaea sp. nov., is mature at 24 mm SL. A geometric morphometric analysis shows: (i) each species of the martinica species-group occupies its own portion of shape space; and (ii) none of the miniature species possess the shapes of small immature M. martinica. While some of the literature suggests that miniaturization may involve paedomorphosis, our results show that the miniatures accelerate to adult body forms.

Three new species-group are established for eastern Palaearctic species of the genus Anthobium Leach, 1819: the consanguineum-group containing A. consanguineum Shavrin & Smetana, sp.n. (China: Yunnan: Gaoligong Shan, Diancang Shan) and A. jaegeri Shavrin & Smetana, sp.n. (Central Nepal: Kali Gandaki Valley); the crassum-group containing A. crassum Shavrin & Smetana, sp.n. (China: Yunnan: Xue Shan, Haba Shan), A. crenulatum Shavrin & Smetana, sp.n. (China: Yunnan: Diancang Shan), A. explanatum Shavrin & Smetana, sp.n. (China: Sichuan: Gongga Shan), and A. farkaci Shavrin & Smetana, sp.n. (China: Sichuan, Sabde); the reflexum-group containing A. reflexum (Reitter, 1891) (Middle Asia), A.deplanatum Shavrin & Smetana, sp.n. (China: Sichuan: Erlang Shan), A. gaoligongshanense Shavrin & Smetana, sp.n. (China: Yunnan: Gaoligong Shan), and A. kashmiricum (Cameron, 1941) (India: Kashmir). The species groups are defined, briefly discussed, and a key to the species included in each group is given. A lectotype is designated for Lathrimaeum reflexum Reitter, 1891. The subgenus Prionothorax Luze, 1905 is synonymized with the nominal subgenus of Anthobium. An additional species of the fusculum group is described: A. transversale Shavrin & Smetana, sp.n. (China: Sichuan: Gongga Shan). The species of each species-group are (re-)described, illustrated, and their geographical distributions are mapped. Anthobium reflexum is recorded from Kyrgyzstan for the first time.

AbstractThe mollissima-subgroup of Pont (1965) belongs to the Fannia serena species-group of Chillcott (1961) in the genus Fannia Robineau-Desvoidy, 1830 (family Fanniidae). A review of the F. mollissima-subgroup, previously known from eleven species, is enlarged to include seven additional species: F. albisquama Wang & Zhang, sp. n., F. biseta Wang & Zhang, sp. n., F. doxonglaensis Wang & Zhang, sp. n., F. mainling Wang & Zhang, sp. n., F. multiseta Wang & Zhang, sp. n., F. nigribasicosta Wang & Zhang, sp. n., and F. tibetana Wang & Zhang, sp. n. A key to the known species of the F. mollissima-subgroup is given. To facilitate comparison of the species, the original diagnosis of the F. mollissima-subgroup has been expanded. The biogeography of the subgroup is discussed, including its origin and evolutionary history, the effect of the uplift of the Tibetan Plateau, and the effect of glacial periods during the Quaternary.
