Short description Identification keys | Morphology | Morphometrics

Anal soft rays: 8; Vertebrae: 36 - 38. Distinguished from other congeners by the following combination of characters: tiny adult body size (largest specimen examined 19.1 mm SL); lateral line incomplete, with 14-17 pores, terminating on flank anterior to vertical through pelvic-fin origin; a distinct dark brown spot at center of caudal-fin base; 9-10 irregular light brown bars along dorsal body surface; axillary pelvic lobe lacking; weakly developed processus dentiformis; dorsal-fin rays iii-iv.8.i; principal caudal-fin rays 8 + 8 (7 + 7 branched caudal-fin rays) (Ref. 88809).

Biology     Glossary (e.g. epibenthic)

Occurs in the mainstream of Sekong river, from moderate flow, over a sandy substrate (Ref. 88809).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00692 (0.00311 - 0.01538), b=3.02 (2.85 - 3.19), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.0   ±0.3 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
