description
Description. A small proportion of males also have an iridescent blue-green or black ocellus on the dorsal fin. The caudal fin is rounded and without “ lyre-tail ” extensions (usually present in A. rupununi, morphologically the most similar species). Pelvic and pectoral fins are lighter than the unpaired fins. Females have clear fins. The sides of the body of males are unpatterned. The dorsum of the body is light tan anterior to the dorsal fin, and gets progressively pinker posterior to the dorsal fin, and on the sides of the body. Each scale is lightly outlined with white or lighter pink. The abdomen is pale, almost white. In females, the basic color is plain light tan. As in males, the abdomens of females are lighter than the rest of the body. The iris of the eye is silver. A faint eye bar is usually visible; however, this character varies with the temperament of the fish. For additional characters see Myers (1932), Taphorn and Thomerson (1978) and Table 3.

diagnosis
Diagnosis. Austrofundulus transilis is the smallest of all species of Austrofundulus. It is distinguished from all other species of Austrofundulus by pastel light tan to pink-grey background body color, and the lack of any black markings on the body. Males of A. transilis have pink to red background color on all fins with occasional blue-green highlights between the fin rays; this fin color pattern is also diagnostic.

discussion
Remarks. Austrofundulus transilis are small, relatively non-aggressive fish when compared to A. limnaeus and the other species described in this paper. Although there is sexual differentiation in the color pattern, it is subtle compared to the other Austrofundulus species.
