Sueviota minersorum, a new species of sponge-dwelling goby (Teleostei: Gobiidae) from Misool, Raja Ampat Islands, Indonesia

Greenfield, David W.; Erdmann, Mark V.; Utama, Ilham Vemandra

A new gobiid species, Sueviota minersorum, is described from 4 specimens, 17.9–23.2 mm SL, collected from inside Theonella tube sponges at 20–22 m depth. The new species has a dorsal/anal-fin ray count of 9/8 and 17 or 18 pectoral-fin rays, all unbranched, and 27 or 28 lateral scales. It furthermore has a basal membrane fully joining the two branched fifth pelvic-fin rays, a character shared with 4 congeners: Sueviota bryozophila, S. lachneri, S. larsonae, and S. tubicola. Sueviota minersorum is most similar to S. lachneri, but differs in having a stocky body with a deep caudal peduncle, not tapering from the mid-body, and in color patterns. It differs from S. bryozophila in having all pelvic-fin rays branched (vs. unbranched), having a single AITO pore (vs. paired ITO pores), PITO and NA pores (vs. absent), and in color patterns. It differs from S. larsonae and S. tubicola by the absence of a frenum (vs. present) and in color patterns.
