簡短描述 檢索表 | 型態特徵 | 形態測量圖

背的軟條 (總數) : 11; 臀鰭軟條: 8. Schistura madhavai differs from all its congeners from peninsular India and Sri Lanka by the combination of the following characters: 8-9 wide post-dorsal bars separated by narrow, white interspaces ¼-? the width of the bars; black bar at the base of the caudal fin arched, its posterior margin vaguely indented at bases of branched caudal-fin rays 3 and 14, wider than the interspaces on the body; 8+8 branched rays on emarginate caudal fin; incomplete lateral line ending beneath the dorsal-fin base; axillary pelvic lobe absent; adpressed pelvic fin just reaching the anus; 7½ branched rays on dorsal fin; pelvic-fin origin on a vertical through the last unbranched dorsal fin ray; and suborbital flap in males absent (Ref. 116162).

生物學特性     字彙 (例如 epibenthic)

Inhabits a small stream about 2 m wide, flowing through sparsely-inhabited tea plantations, at an elevation of about 1000 m above sea level and with substrate consisting of pebbles and gravel. Prefers the faster-flowing areas of the stream. Occurs syntopically with the cyprinids Devario malabaricus (Jerdon), Puntius titteya (Deraniyagala), Pethia nigrofasciata (Günther), Rasbora dandia (Valenciennes), Rasboroides rohani (Batuwita, Silva & Edirisinghe), and the osphronemid Belontia signata (Günther). The introduced guppy Poecilia reticulata Peters was also recorded from this stream (Ref. 116162).
