description
Description Morphometric data appear in Table 2. Largest male examined 29.1 mm SL; largest female examined 24.0 mm SL. Dorsal profile convex from snout to end of dorsal-fin base, approximately straight on caudal peduncle. Ventral profile gently convex from lower jaw to end of anal-fin base, nearly straight on caudal peduncle. Body moderately deep, compressed, greatest body depth in vertical just anterior to anal-fin origin. Eye positioned on dorsal portion of each side of head. Snout blunt. Urogenital papilla cylindrical and short in males, pocket-shaped in females. Tip of dorsal and anal fins pointed in males, rounded in females; dorsal fin with long filamentous ray, reaching posterior margin of caudal fin. Dorsal-fin rays unbranched. Caudal fin round. Pectoral fins elliptical. Posterior margin of each pectoral fin reaching vertical through base of 7 th anal-fin ray in males, through urogenital papilla in females. Pelvic fins short and pointed, tip reaching between base of 1 st and 3 rd anal-fin rays in males, between anus and urogenital papilla in females. Dorsal-fin origin on vertical between base of 3 rd and 4 th anal-fin rays; dorsal-fin origin between neural spines of vertebr

diagnosis
Diagnosis Distinguished from all other species of the subgenus Simpsonichthys by the presence of longitudinal rows of light blue dots on flank in males (vs. absence) and long filamentous ray on tip of dorsal fin in males, reaching posterior portion of caudal fin (vs. reaching basal portion of caudal fin). Distinguished from all congeners by the unique combination of the following features: pelvic fin present (vs. pelvic fin absent), second pharyngobranchial teeth absent (vs. present), ventral process of posttemporal short (vs. long), 18 - 19 dorsal-fin rays in males and 14 - 15 in females (vs. 15 - 17 in males, 12 - 13 in females), long filamentous ray on tip of dorsal fin in males (vs. filamentous rays short or absent), five alternating bright blue and pink to red bars on head side in males (vs. never a similar color pattern), pectoral fin pink with blue spots in males (vs. hyaline), and no black spots on dorsal fin in males (vs. black spots on basal portion of dorsal fin).
