Краткое описание
определительные ключи | морфология | морфометрия
членистые (мягкие) лучи спинного плавника (общее число) : 7 - 10; членистые (мягкие) лучи анального плавника: 14 - 16; позвонки: 34 - 36. Atlantirivulus paranaguensis can be diagnosed from all its congeners by the
following combination of characters: lateral line divided into two sections (vs. single); lateral line with one neuromast by scale (vs. lateral line often interrupted by scales without neuromasts); caudal fin oval in both sexes (vs. sub-truncate at least in males); caudal fin margins in males with high concentration of melanophores, forming a well-delimited black ventral margin about thrice wider than a black dorsal margin (vs. melanophores, when highly concentrated, forming diffuse black zones on the entire caudal fin, darker and slightly wider on the ventral portion); venter white (vs. yellow); caudal-fin spot always conspicuous in females (vs. spot pale or absent in females above 2.8 cm SL) (Ref. 102354).
Inhabits shallow swamps and channels connected to small streams, within dense forest areas, in small river basins flowing into the Paranaguá bay. The water of the sampling area is light yellow or tea-like colored and the habitat bottom is composed of litter (Ref. 102354).
