Etymology: Sicyopterus: Greek, sika, sikya = cucumber + Greek, pteron = wing, fin (Ref. 45335); erythropterus: åñõèñïæ (eruthros) red, and ðôåñõæ (pteron), fin, to characterise its red anal fin (Ref. 90225).
Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic; amphidromous. Tropical
Asia: 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 three clefts (one anteriorly and two midlaterally) on upper lip, with smooth lip and with a second dorsal fin with 1 spine and 10 segmented rays. The sexual dimorphism is well developed with males with fewer scales in LS (51-55 vs. 56-58) and PD (0-15 vs. 19-26) and less teeth in lower jaw (3-6 vs. 7-9) than females. A distinctive red pattern on the anal fin, more or less marked. Caudal fin branched rays 12-13 (Ref. 90225).
