Eviota gunawanae, a new microendemic dwarfgoby from the Fakfak Peninsula, West Papua, Indonesia (Teleostei: Gobiidae).

A new species of dwarfgoby, Eviota gunawanae, with a cephalic sensory-canal pore pattern lacking only the IT and NA pores and with the AITO pore positioned far forward and opening anteriorly, is described from the Fakfak Peninsula in the Bird’s Head Seascape of western New Guinea, West Papua Province, Indonesia. It has a dorsal/anal-fin-ray formula of 8/7, 16 unbranched pectoral-fin rays, the fifth pelvic-fin ray present, very long anterior tubular nares, a distinctive double black spot at the caudal-fin base, and no narrow horizontal line of melanophores crossing the pectoral-fin base. In life, it has a maroon stripe down the midline of the body, with elongate white spots above it posteriorly and two white lines over the abdomen. E. gunawanae is most closely related to E. tetha. The new species appears to represent the eighth known microendemic species from this remote reef location in West Papua, highlighting the biodiversity conservation importance of the Fakfak Peninsula’s reefs
