Etymology: Rectoris: Latin, rector, -oris = leader;  longibarbus: Derived from the Latin word 'longus' ( = long) and 'barbus' ( = barbel), in allusion to the presence of a pair of well-developed maxillary barbels. A noun in apposition..

Environment: milieu / climate zone / depth range / distribution range Ecology

Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 11; Anal soft rays: 8. Differs from two other congeners, i.e. Rectoris mutabilis and R. posehensis, by having a dumbbell-like (vs. slender) posterior chamber of the gas bladder, almost equal to (vs. twice as long as) the anterior chamber, and longer rostral barbels (vs. shorter) than eye diameter, with their lengths 21.0-24.7% of HL (vs. 10.2-18.8). Similar to R. posehensis in having a longitudinal black stripe running along the lateral line on the flank, but can be further diagnosed from this species in having a slightly papillated posteromedian patch on the median plate of the lower lip (vs. no patch); and similar to R. mutabilis in the shared presence of a papillated posteromedian patch on the median plate of the lower lip, but further differs from this species in its longitudinal black stripe running along the lateral line on the flank (vs. stripe absent) (Ref. 93096).

Biology     Glossary (e.g. epibenthic)

Found in a temporary pool of water spilled from a karst cave during the annual rainy season. (late June to August). Sympatric with Rectoris posehensis, Yunnanilus jingxiensis, Pseudogyrinocheilus longisulcus and Cophecheilus bamen (Ref. 93096).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5312   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00955 (0.00451 - 0.02020), b=3.04 (2.86 - 3.22), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
