LEPTOLEBIAS MYERS, 1952 View in CoL View at ENA

Leptolebias Myers, 1952: 140 View in CoL (type species: Cynopoecilus marmoratus Ladiges, 1934 View in CoL , by original designation; first proposed as a subgenus of Cynolebias Steindachner, 1876 View in CoL ).

Diagnosis: Distinguished from all other genera of the Cynopoecilina ( Notholebias , Cynopoecilus , and Campellolebias ) in having caudal fin elongate, longer than deep (vs. short, deeper than long), single anterior supraorbital neuromast ( Fig. 2 View Figure 2 ) (vs. two or three), and distal third of dorsal fin in males without dark pigmentation (vs. extending pigmentation). Also distinguished from Notholebias by the absence of the second pharyngobranchial teeth, dermosphenotic and contact organs on male pectoral fin (vs. presence), opercular region with red reticulation in males (vs. red bars), and by having a wide, triangular basihyal ( Fig. 3 View Figure 3 ) (vs. narrow, rectangular).

Distribution: Species of Leptolebias are found in the temporary pools of broad coastal plains, in two areas, separated by about 500 km: (1) between Maricá and Vila de Cava, Rio de Janeiro state, south-eastern Brazil ( Fig. 4 View Figure 4 ), and (2) between Itanhaém, southern São Paulo state, and river basins draining into Paranaguá bay, Paraná state, southern Brazil ( Fig. 5 View Figure 5 ).
