Abstract:
Eurycercus (Bullatifrons) norandinus sp. nov. is described from Lago de Tota, Boyacá, Colombia. It differs from other species of subgenus Bullatifrons in the lower number of denticles on the dorsal margin of the postabdomen, the lower number of denticles on the postadominal claw, and the higher number of denticles on scrapers 2, 3 and 4 of trunk limb II. Regression statistics comparing the new species with other species of the subgenus indicate that during ontogeny, the rate of increase in teeth number of the dorsal margin of the postabdomen in relation to postabdominal length is higher than in other species. With the present record, the distribution of Eurycercus expands to the central part of the Neotropical Region and that of subgenus Bullatifrons to South America.
