Abstract
Egglestonichthys rubidus n. sp. is described from two male specimens, 15.5-21.2 mm SL, collected from mud-bottom habitat in 18 m depth at Milne Bay Province, Papua New Guinea. Diagnostic features include: segmented dorsal and anal rays 7; pectoral rays 17-18; lateral scales 27-28; transverse scales 7; predorsal scales 13-18, extending to middleof interorbital; head and body scales entirely ctenoid, including breast, belly, prepelvic area, pectoral-fin base, predorsal, cheek, and opercle; cheek and opercle scales extend ventrally to lower margin; head pores absent; transverse papillae pattern on head, some rows raised, forming ridges; head, body, and fins generally red to reddish brown, outer edge of dorsal and anal fins with frost-like, white speckling. The new species differs from its four congenerics incounts for segmented dorsal and anal rays, pectoral rays, lateral scales, transverse scales, predorsal scales, arrangement of cephalic sensory papillae, and scale composition.
