Spectrolebias brousseaui is described from a temporary pool from the upper río Mamoré basin, Departamento Santa Cruz, Bolivia. The new species is distinguished from all congeners, by the overall dark blue coloration on the posterior two-thirds of body with bright blue iridescent spots vertically aligned in males. Spectrolebias brousseaui differs from all other species of the genus, except S. filamentosus, for having pelvic fins separated by a space (vs. pelvic fins in contact), long filaments at the tip of the dorsal and anal fins in males (vs. absence of filaments or presence only on dorsal fin in S. semiocellatus and S. inaequipinnatus, or the presence on the anal fin in S. chacoensis), and presence of contact organs on the scales of the flanks in males (vs.absence of contact organs on flanks in all remaining Spectrolebias species).

A new species of Lipogramma is described from submersible collections at 122–165 m depth off the coast of Roatan, Honduras, in the western Caribbean. The new species is distinguished from all other species in the genus by its bright blue coloration on the head, nape, and dorsal portion of the trunk beneath the spinous dorsal fin, a prominent round black blotch below the origin of the spinous dorsal fin, and a high number of gill rakers. A molecular phylogeny based on mitochondrial and nuclear genes shows that the new species belongs to a clade containing L.levinsoni, L.regia, and L.anabantoides. At Roatan, submersible observations of this and other Lipogramma species indicate clear, interspecific habitat partitioning by depth and substrate.

A New Species

The author obtained, in the early part of last September, at Brixham, in Devonshire, seven specimens of a species of Gurnard, which has been known for thirty years past to the fishermen there under the name of Finned Captains. This he ascertained to be the Trigla lucerna of Brunner. The species is known as an inhabitant of the Mediterranean, where it was first noticed by Rondeletius, but mistaken by him for the T. cuculus of Linnæus. Since then, Brunner noticed it at Marseilles, Risso at Nice, Leach at Malta, and Cuvier at Naples; but it had not been previously observed by any naturalist on the British coasts. The largest specimen obtained by the author is 10½ inches long. The back is light red, the pectoral fins dark blue, the sides marked by a silvery band from the gill-cover to the tail; the lateral line smooth, and formed by numerous semicircular plates, beautifully radiated at their free margin ; the scales thin, large, and entire; the second ray of the first dorsal fin very long, so as to reach, when folded down, beyond the sixth ray of the second dorsal fin.

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).

We describe a new species of fan-throated lizard of the genus Sitana from the Deccan peninsula of India. The new species is from the Sitana sivalensis clade and can be readily diagnosed morphologically from S. sivalensis, S. fusca and S. schleichi by having the dewlap extending beyond forearm insertion. The new species differs from all other congeners in the combination of morphological characters such as a feebly serrated dewlap with a dark blue line on the throat in adult males (versus  a well serrated dewlap with a bright blue patch and orange spots in S. ponticeriana complex), small body size (versus a large body size in S. gokakensis and S. thondalu) and a relatively smaller dewlap size (relatively larger in S. laticeps, S. spinaecephalus, S. dharwarensis, S. gokakensis, S. thondalu, S. marudhamneydhal, S. ponticeriana and S. visiri). The new species was found to be commonly distributed in arid and open habitats as well as in farmlands and plantations in northern Andhra Pradesh, eastern Madhya Pradesh and most parts of Chhattisgarh and Odisha states.

Cirrhilabrus cyanogularis, sp. nov., is described on the basis of the holotype and three paratypes from Banguingui Island, Sulu Archipelago, Philippines, and a paratype from Sulawesi, Indonesia. The new species belongs to a complex consisting of C. filamentosus (Klausewitz), C. rubripinnis Randall & Carpenter, and C. tonozukai Allen & Kuiter. Aside from similar nuptial male coloration, the four species share the following character combination: a single row of cheek scales; dorsal-fin spines taller than dorsal-fin rays (slightly incised between spinuous and soft dorsal fin in C. rubripinnis and C. cyanogularis; last three dorsal-fin spines converging to form a single filament in C. tonozukai and C. filamentosus); relatively long pelvic fins (reaching past anal-fin origin); and isthmus and breast blue. The new species differs from the other members of the complex in lacking a dorsal filament, as well as possessing six predorsal scales, more extensive blue coloration on the isthmus, lower head and breast, and a soft dorsal fin with narrow black, medial stripe. The status of Klausewitz’s Cirrhilabrichthys is briefly discussed.

A New Species

The new cichlid species Gymnogeophagus tiraparae is described from the río Negro and río Tacuarí basins (Uruguay). The new species is distinguished from other Gymnogeophagus species by the unique presence of the following characters: adipose hump on head deeper than the dorsal-fin upper border, adipose hump with anterior profile vertical, extending from the upper lip to the dorsal-fin origin, absence of transversal bands on body; two horizontal series of moderately elongated light blue dots between dorsal fin spines, and a series of light blue stripes between soft rays, sometimes merged with the second series of elongated dots, always with a red ground color between series of dots, and caudal fin with dots vertically aligned on its distal border. According to these characters and a recent molecular phylogenetic analysis, the new species is closely related to G. gymnogenys.

ABSTRACT We describe a new species of a substrate-brooding Gymnogeophagus , based on coloration characters. The new species can be distinguished from the remaining substrate-brooding species in the genus by the unique pigmentation of the dorsal fin which consists of light blue, diagonal stripes over a red background in the spiny section and a combination of round, elliptic, and elongated bright blue spots over a red background in the soft section. It can be further distinguished from all other species of Gymnogeophagus by the following combination of characters: a discontinuous bright blue band above the upper lateral line in the humeral area, light blue roundish spots over a red to orange background on the anal fin, and conspicuous bright blue horizontal bands on body. The new species inhabits a wide range of freshwater habitats in the lower rio Uruguay basin, Rio de la Plata coastal drainages and Atlantic Ocean coastal drainages in Uruguay.

Simpsonichthys suzarti, new species, from the floodplains of the lower Rio Pardo, northeastern Brazil, is described. It is a member of a clade, herein termed S. constanciae species group, which is diagnosed by the eyes laterally positioned on the head and a derived pattern of cephalic neuromast arrangement, in which the supraorbital series is interrupted by a median interspace. It differs from all other species of the group in having the anal fin rounded in males and by the distinctive color pattern of males, including the presence of reddish brown bars along the whole flank, reticulate dark brown marks on the dorsal fin and oblique dark brown bars on the anal fin. A key to the species of the S. constanciae group is provided.
