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); maculata: Name from the Latin word 'maculata' meaning spot, referring to the black basicaudal spot.

背的软条 (总数) : 13 - 14; 臀鳍软条: 11 - 13. Diagnosis: A small species with dorsal and anal fins set far back on body, but less posterior than in Allotoca dugesi. Predorsal length 64-68%. Dorsal origin slightly ahead of anal origin. Dorsal rays usually 13 or 14. Anal rays usually 11-13. Lateral scales 28-32. Mandibular pores absent. Adult fins dimorphic, longer in males which have dorsal and anal fins rounded and elevated. Deep body and compressed. The coloration is distinctive, fins mostly clear, one or more irregular dark spots on caudal peduncle, females with 3-6 lateral blotches of iridescent blue, males with a lateral series of fine dark spots. Diploid chromosome number 48, no metacentrics (Ref. 35111).
鉴别: 一种小的种与背鳍与臀鳍组相距遥远地在身体上, 但是更少的在后部超过在 Allotoca dugesi 中. 前背的长度 64-68%. 在臀鳍起点之前些微地的背鳍起点。 背鳍鳍条通常 13 或 14. 臀鳍硬棘通常 11-13. 侧面的鳞片 28-32. 颚骨孔不存在。 成鱼的鳍双型性的, 更长的在雄性中那里有背鳍与臀鳍圆形与升高的。 身体纵深而扁长形的。 颜色是特殊的, 鳍大部份清澈, 一个或多个不规则的深色斑点在尾梗上, 雌性有三个 -6个侧面斑块蓝色虹彩的, 雄性有一個深色細斑點的側線列。 雙重的 48 號染色體, 沒有 metacentrics.(參考文獻 35111)
