Austrolebias paucisquama is described from the rio Vacacaí drainage, a tributary to the rio Jacuí, Rio Grande do Sul, Brazil. The new species belongs to the Austrolebias alexandri species-group, by sharing the apomorphic bright blue iridescence and dark gray pectoral fins in males. It is distinguished from other species of this group by having fewer scales around caudal peduncle (12) and fewer dorsal-fin rays in males (17-21). The lack of contact organs on the inner surface of the pectoral fin in males and the color pattern of females - ground color light brownish, sides of body with a variable number of relatively large dark black spots distributed mostly on posterior portion of body - distinguish A. paucisquama from all other species of the genus.

A New Species

Hypsolebias tocantinensis n. sp. is described from a temporary pool located in the rio Tocantins basin, Maranhão stateBrazil. Hypsolebias tocantinensis belongs the H. flammeus species-group. It is the first occurrence of genus Hypsolebiasin Maranhão state. This new species differs from all other species of that group, except Hypsolebias flammeus (Costa,1989), Hypsolebias multiradiatus (Costa &Brasil, 1994) and Hypsolebias brunoi (Costa, 2003), by male color pattern andby the presence of a metallic blue sheen surrounding the black spots in the female. It differs from H. flammeus, H. multi-radiatus and H. brunoi by the shape of the dorsal and anal fins (rounded vs. pointed) and by the orientation of the reddishbrown bars in males (diagonal vs. vertical). Hypsolebias tocantinensis differs from all other Hypsolebias by the presenceof, in females, irregular light brown stains on the anal fins and by the pattern of the metallic blue sheen around the blackspots (completely surrounding the black spots while in congeners this blue sheen is either absent or present in vertical bars).

Apogonichthyoides is resurrected from Apogon (Ostorhinchus) as a valid genus with 19 species. Members of this genus are mostly tannish brown to brownish-black in body color. The head and body usually have brownish to blackish spots (sometimes stripe-like), a darkish cheek line and usually two body bars. An ocellus may be present below the lateral line on the body or absent. One or more caudal-peduncular bars and/or a basicaudal spot are often present. Insertion patterns of supraneurals and pterygiophores are given for 11 species. Apogonichthyoides umbratilis, a new species, has 14 pectoral rays and five bars (three faint) on the body and caudal peduncle. Color pattern of the new species suggest relationships with Apogonichthyoides gardineri, A. timorensis and A. opercularis. Descriptions and illustrations of the latter two species are provided for comparison. Apogonichthyoides gardineri, a rare, deep-water species is characterized by 14 pectoral rays, two bars on the body and one wide bar near the base of the caudal peduncle. Specimens of Apogonichthyoides timorensis usually have 15–16 pectoral rays and two or three bars on the body and caudal peduncle. Specimens of Apogonichthyoides opercularis have nine soft anal rays and 10 soft dorsal rays. A key to eight species included in the timorensis species group is provided. A lectotype and paralectotypes are designated for the syntype series of Apogon opercularis. New name combinations follow: Apogonichthyoides atripes, A. brevicaudatus, A. cantoris, A. chrysurus, A. euspilotus, A. gardineri, A. heptastygma, A. niger, A. opercularis, A. pharaonis, A. pseudotaeniatus, A. regani, A. sialis and A. timorensis. Previous usage includes: Apogonichthyoides enigmaticus, A. nigripinnis, A. taeniatus and A. uninotatus

ABSTRACT A new species of Hyphessobrycon belonging to the Hyphessobrycon heterorhabdus species-group from the lower rio Tapajós, state of Pará, Brazil, is described. The new species is allocated into the Hyphessobrycon heterorhabdus species-group due to its color pattern, composed by an anteriorly well-defined, horizontally elongated humeral blotch that becomes diffuse and blurred posteriorly, where it overlaps with a conspicuous midlateral dark stripe that becomes blurred towards the caudal peduncle and the presence, in living specimens, of a tricolored longitudinal pattern composed by a dorsal red or reddish longitudinal stripe, a middle iridescent, golden or silvery longitudinal stripe, and a more ventrally-lying longitudinal dark pattern composed by the humeral blotch and dark midlateral stripe. It can be distinguished from all other species of the group by possessing humeral blotch with a straight or slightly rounded ventral profile, lacking a ventral expansion present in all other species of the group. The new species is also distinguished from Hyphessobrycon heterorhabdus by a 9.6% genetic distance in the cytochrome c oxidase I gene. The little morphological distinction of the new species when compared with its most similar congener, H. heterorhabdus, indicates that the new species is one of the first truly cryptic fish species described from the Amazon basin.

A New Species

A new species of the romaleid grasshopper genus Zoniopoda Stål (Romaleidae: Romaleini) is described and illustrated from the Sierras Chicas of Córdoba Province, central Argentina. A cladistic analysis based on morphological characters indicates that the genus Zoniopoda constitutes a monophyletic group and that Zoniopoda serrana n. sp. must be assigned to Iheringi species group based on synapomorphies of the pronotum and body color. The new species is similar to Z. similis Bruner from Paraguay, Bolivia and Brazil, from which it can be distinguished by the color pattern of the body, shape of the pronotal dorso-median carina and characters of the male terminalia and epiphallus. This paper has been formatted with embedded links to images of the type specimen, maps based on georeferenced specimen data for the genus and an updated key to the species of Zoniopoda available on the Orthoptera Species File (OSF) online (http://orthoptera.speciesfile.org).
