Kort beskrivning
Bestämningsnycklar | Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt) : 1; Mjukstrålar i ryggfenan (totalt) : 7; Mjukstrålar i analfenan: 26. Sundolyra latebrosa can be distinguished from other bagrid species, except for Olyra species, in having a combination of an anguilliform body, a reduced supraoccipital posterior process and the lack of first dorsal spinelet. It can be diagnosed from Olyra species in having the following characters: first proximal dorsal-fin radial inserting on the 4th (vs. 11th-12th) vertebra; first dorsal-fin lepidotrich ossified into a spine (vs. not ossified); anterior edge of the pectoral spine smooth (vs. 8-9 serrae); adipose fin in contact with base of the last dorsal-fin ray (vs. separated by a distance of at least 16% SL); 26 anal-fin rays (vs. 15-21); and 17 principal rays (vs. 12-13) on the caudal fin (Ref. 104298).
Body shape (shape guide): elongated.
Inhabits a hillstream. Found in a crevice between large boulders at the bank of a moderately steep, fast-flowing stream with clear (low turbidity) and slightly alkaline (pH 7.9) water and with substrate consisting of large boulders and cobble. Barbodes cf. binotatus (Cyprinidae) was the only other species collected when the stream was sampled. Reaches up to 20 cm TL based on interviews with the locals (Ref. 104298).
