Actinopterygii (ray-finned fishes) > Perciformes (Perch-likes) > Gobiidae (Gobies) > Sicydiinae
Etymology: Sicyopterus: Greek, sika, sikya = cucumber + Greek, pteron = wing, fin (Ref. 45335);  calliochromus: Sicyopterus calliochromus differs from S. longifilis with its distinctive gold and black band pattern and the female’s bulbous urogenital papilla with fimbriate projections around a tubular ovipositor. Moreover, it differs in having fewer scales in predorsal midline (10-16 vs. 18-21) and in transverse forward series (14-18 vs. 17-21) and fewer branched rays in caudal fin (13 vs. 14-15). (Ref. 90225).

Short description Morphology | Morphometrics

A Sicyopterus with only 2 lateral clefts on upper crenulated lip and a second dorsal fin with 1 spine and 10 segmented rays. A distinctive gold colour on entire body, both in males and females, with two ventral black bands from pectoral base to upper hypural, a black mask on the front of the head below the eyes and a black spot on the ventral part of the head. Females with bulbous urogenital papilla with fim briate projections around a tubular ovipositor, which seems to be unique in Sicyopterus species. Fins particularly long both in males and females. (Ref. 90225).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01122 (0.00514 - 0.02450), b=3.04 (2.87 - 3.21), based on all LWR estimates for this body shape (Ref. 93245).
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months ().
Vulnerability (Ref. 59153):  Low vulnerability (15 of 100) .
