簡短描述
型態特徵 | 形態測量圖
背棘 (總數): 2; 背的軟條 (總數): 5; 臀鰭軟條: 10; 脊椎骨: 34. Tatia melanoleuca is readily distinguished from all congeners, except T. carolae and T. musaica, by the strongly contrasting, dark coloration on the dorsal and to varying degrees lateral and ventrolateral portions of the body that is distinctly demarcated from the lightly colored regions that are translucent in life on the remainder of the body (vs. a variety of alternative coloration patterns in congeners, none of which is comparable to this pigmentation pattern). It differs from T. musaica and T. carolae by the lack of dark pigmentation on the lower lobe of the caudal fin (vs. a bilobed pattern of dark pigmentation in that region in T. carolae, or an extension of the dark body pigmentation onto the basal portions of the lobe in T. musaica) and having 34 vertebrae (vs. 35 or 36 in T. carolae and 35 in T. musaica). In addition, it is distinct from T. carolae in the dark pigmentation that is uniformly continuous across the portion of the lateral line on the caudal peduncle (vs. with the area bordering the lateral line unpigmented and forming distinct, narrow, posteriorly dorsally angling white stripe within the dark pigmentation on the caudal peduncle), the lack of dark pigmentation on the upper lobe of the caudal fin or with such pigmentation barely extending onto the lobe (vs. a bilobed pattern of dark pigmentation extending onto the lobe in that region), the narrower interorbital width (42.0-42.9% vs. 51.8-62.4% HL), shallower snout depth (34.5-38.5% vs. 43.4-47.5% HL), shorter posterior internarial distance (26.0-29.8% vs. 33.7-38.8% HL) and shorter caudal-peduncle length (18.8-19.5% vs. 22.5-25.3% SL). It further differs from T. musaica in having the following characters: an unpigmented region anterodorsal of the orbits either in the form of a rounded spot or a broad median band extending anteriorly to the upper lip (vs. with solid dark pigmentation in that region), the unpigmented dorsal-fin spine (vs. a dusky spine), the lack of dark pigmentation on the dorsal surface of the pectoral-fin spine other than basally (vs. dusky pigmentation extending at least one-half the length of the spine), the location of dark pigmentation on the body other than on the caudal-peduncle dorsal to the horizontal through the middle of the orbit (vs. dark pigmentation broadly extending ventral of that line and reaching to the ventral midline anterior to the anal-fin base), the deeper overall body as reflected in the greatest body depth (23.4-25.6% vs.17.9-21.8% SL) and deeper caudal-peduncle depth (13.9-14.5% vs. 9.6-12.0% SL) (Ref. 97857).
Found in a 2 m deep stretch of the river (Rio Jamanxim) characterized by clear water, somewhat lentic to slow flowing waters and substrate composed primarily of sand and rocks with some submerged tree trunks. Collected near the river margin during twilight while searching for food on the water surface (Ref. 97857).
