简单描述 型态特徵 | 形态测量图

背棘 (总数): 1; 背的软条 (总数): 5; 臀鳍软条: 10 - 11; 脊椎骨: 34 - 36. Diagnosed from all other species of Tatia by the following characters: male anal fin with sharp pointed tip; the first unbranched anal-fin ray divided into 3-4 segments; and the last branched ray reduced. Can be distinguished from most of its congeners, except Tatia aulopygia Tatia intermedia and Tatia gyrina, by having a wide mouth, width 54.0-59.7% HL (vs. 39.0-53.3% HL). Additional characteristics for recognition of Tatia brunnea are diagnostic in combination: nasal ossified with wide medial flanges partially sutured to lateral margin of mesethmoid; ribs 9-10; post-Weberian vertebrae 34-36. Other features useful for distinguishing Tatia brunnea include details in coloration, such as: border of mouth whitish, contrasting with dark head; posterior border of nuchal shield usually whitish or pale; pectoral-fin spine usually with transverse bands; caudal fin usually whitish with scattered dark brown blotches; and head width 86.6-93.4% HL (Ref. 79512).

生物学特性     字汇 (例如 epibenthic)

Sympatric with Tatia intermedia in some rivers in Suriname and French Guiana and also in the Trombetas river (Ref. 79512). Rather rare, occurs in the slow parts of creeks. May easily be mistaken as juveniles of Glanidium leopardus with which it is distinguished by means of the pectoral spines (having projections vs. smooth) and by the number of rays in the anal fin (8-9 vs. 12-14). Sexual dimorphism in males appear at a length of 3.5-4.0 cm. Its small size makes it interesting for aquarists (Ref. 35381). Reported sizes at sexual maturity are above 5.46 cm SL and above 7.0 cm SL (Ref. 79512).

相当稀有, 出现于小溪的缓流的河段中。 容易被误认为是 狮纹小项鳍鲶[Glanidium leopardus] 的稚鱼它被藉着胸棘 (有突出 vs. 平滑的) 的方法区别与藉由在臀鳍中的鳍条的数字.(8-9 vs.12-14) 在雄性的性的同种二形出现在体长 3.5-4.0 公分。 它的体型小使它受观赏水族爱好者喜爱。 (参考文献 35381)
