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..

簡短描述
檢索表 | 型態特徵 | 形態測量圖
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).,
more dorsal
一種小的, 圓錐體-有齒的 goodeid 描述的特徵具有那在:之後 在一個瘦長的毛簇中的分開眶前骨與前鰓蓋骨感覺管與 trophotaeniae; 有孔 2b-4 一在眶上管系統; 12-18個狹窄的縱帶沿著側面中央; 35-38個脊椎骨; 與 A. dugesi 相較更多的臀鰭棘條, 典型地 14(vs.11 或 12
而且比較雙重的染色體, 2N=48 telocentrics 與 subtelocentrics;(vs.2N=26個包括 22 metacentrics) 與 A. maculata, 更多的背鰭鰭條相較, 典型地 16(vs.13 或 14) 而且有顎的孔 4;(vs.0) 與 A. diazi, A. catarinae 與 A. meeki 相較, 典型地它有較少的前鰓蓋骨孔 8(vs.10 或者 11), 較少的眶前骨孔典型地 4(vs.5), 在雄魚尾鰭上缺乏 metacentric 染色體 , 與一個深色條紋.(參考文獻 58357),
更背部的
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).
主要生活在淺水區 (15-26 公分) 在漂浮的植物 (布袋蓮, 菌絲藻與一個像焊菜屬的植物一樣的植物) 的下面沿著水池的逐漸傾斜側邊北方部。 採集自安靜水池.清澈的對黝暗的水, 藉由沙子，淤泥，岩石與大圓石的底部.(參考文獻 58357)
