LEPTOLEBIAS CITRINIPINNIS ( COSTA, LACERDA & TANIZAKI, 1988) View in CoL

Cynolebias citrinipinnis Costa, Lacerda & Tanizaki, 1988: 22 View in CoL [type locality: swamp in a restinga, Município de Maricá, Estado do Rio de Janeiro, Brazil, about 22°S, 43°W (Zacarias, Barra de Maricá, 22°57′52.6″S, 42°52′49.3″W); holotype, MZUSP 37199].

Material examined: Brazil, Rio de Janeiro, Maricá: MZUSP 37199, holotype, male, 27.2-mm SL; MNRJ 11310, three paratypes; MZUSP 37198, six paratypes; MZUSP 37197, three paratypes; UFRJ 175, 1 (c&s); UFRJ 2202, 14; UMMZ 231543, six; UFRJ 184, 2; UFRJ 2202, 14; UFRJ 3679, three (c&s); UFRJ 3036, 5; UFRJ 4396, 10; UFRJ 4397, 5; UFRJ 4399, 6; UFRJ 4400, 13; UFRJ 4401, 2; UFRJ 4402, ten (c&s); UFRJ 4403, one; UFRJ 4404, 11; UFRJ 4405, 5; UFRJ 5187, 19; UFRJ 6304, 16; UFRJ 6305, 4; MNRJ 19432, 22; MNRJ 15400, 8; temporary swamp, Zacarias, Barra de Maricá; MNRJ 17684, 7; swamp at street 47, Jardim Atlântico, Itaipuaçu.

Diagnosis: Distinguished from all other species of the genus except L. opalescens in having dorsal-fin origin in vertical between base of seventh and ninth anal-fin rays (vs. between base of second and sixth anal-fin rays). It is distinguished from L. opalescens by having caudal fin elliptical (vs. lanceolate), and dark-reddish brown pigmentation diffuse on distal margin of dorsal and anal fins, and dorsal and ventral margin of caudal fin in males (vs. with distinctive red marginal stripes).

Distribution: Maricá coastal lagoon system, between Itaipuaçu and Barra de Maricá, Rio de Janeiro state, south-eastern Brazil ( Fig. 5 View Figure 5 ).

Habitat and conservation: Shallow temporary swamps (about 20–100-cm deep) in the coastal Restinga, between sand dunes, near the sea. Terrestrial marginal vegetation: mainly comprising Cactaceae and Bromeliaceae .; Aquatic vegetation: dense and diversified. Water: tea-coloured and acidic (pH 4.2–5.8), with litter at the bottom. No other fish species are present. The area of occurrence of L. citrinipinnis partially overlaps an official area of environmental protection.
