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).
Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic; amphidromous. Tropical
Asia: Currently known only from the Tirawiwa River, a major tributary of the Wapoga River, which flows into the eastern side of Cenderawasih Bay, Papua Province in Indonesia.

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).
