Abstract

Encrasicholina integra sp. nov. is described from 10 specimens collected in Manokwari, West Papua, Indonesia. The new species is most similar to Encrasicholina oligobranchus (Wongratana 1983), which is redescribed, in sharing a short upper jaw with the posterior tip just reaching to the preopercle anterior margin, the dorsal and anal fins with three unbranched rays, a bony urohyal without fleshy knobs, and similar numbers of gill rakers. However, the former is characterized by a shorter head (its length 25.9–27.2% SL vs. 28.3–29.8% in E. oligobranchus), maxilla (its length 17.1–18.3% SL vs. 19.0–20.7%), and mandible (its length 17.5–18.7% SL vs. 19.1–20.5%), in addition to a deeper body (its depth 15.1–16.4% SL vs. 13.3–15.3%) and longer pelvic fin (9.3–10.2% SL vs. 8.7–9.4%).
