Etymology: Allotoca: Greek, allos = other + Greek, tokos = birth (Ref. 45335). The transliterated Latin terminal part of the compound name ('tocus') was changed to 'toca', thus the genus is feminine (Ref. 35111); goslinei: Named for William A. Gosline, for his work on cyprinodontoid fishes.
Eponymy: Dr William Alonzo Gosline (1915–2002) was an ichthyologist and botanist at the University of Michigan. [...] (Ref. 128868), visit book page.

A small, cone-toothed goodeid characterized with the following: divided preorbital and preopercular sensory canals and trophotaeniae in an elongated rosette; presence of pores 2b-4a in the supraorbital canal system; 12-18 narrow vertical bars along midside; 35-38 vertebrae; compared with A. dugesi more anal-fin rays, modally 14 (vs. 11 or 12
and more diploid chromosomes, 2N = 48 telocentrics and subtelocentrics (vs. 2N = 26 including 22 metacentrics); compared with A. maculata, more dorsal-fin rays, modally 16 (vs. 13 or 14) and in having mandibular pores 4 (vs. 0); compared with A. diazi, A. catarinae and A. meeki, it has fewer preopercular pores modally 8 (vs. 10 or 11), fewer preorbital pores modally 4 (vs. 5), absence of metacentric chromosomes, and a dark band on the male caudal fin (Ref. 58357).,

Occurs mainly in shallow water (15-26 cm) underneath floating plants (water hyacinth, filamentous algae and a nasturtium-like plant) along the gradually sloping north side of the pool. Collected from quiet pool of clear to murky water, with substrate of sand, silt, rocks and boulders (Ref. 58357).
