Descrição breve
Chaves de identificação | Morfologia | Morfometria
Espinhos dorsais (total) : 7; Raios dorsais moles (total) : 11; Espinhos anais: 1; Raios anais moles: 11. This species is distinguished by the following characters: D VI-I,11; A I,11; pectoral-fin rays 17; scales in longitudinal series 52-54; no scales on head, pectoral-fin base, and prepelvic region; body with cycloid scales anteriorly, becoming ctenoid posteriorly; no preopercular sensory canal and pores; gill opening extending forward to a vertical at posterior edge of preopercle; the first four dorsal-fin spines with short, filamentous tips; lanceolate caudal fin, longer than head, 2.3-2.7 in SL; distinct sexual dichromatism, male characterized by 5 brown saddles on back, 7 orange-brown bars on ventral half of body from level of dorsal-fin origin to base of last anal ray, prominent black bar present across outer two thirds of last two anal-fin rays, pale yellow pelvic fins with bright yellow spots; male and female with mid-lateral row of alternating large and small rectangular blotches within pair of thin stripes from the pectoral fin to caudal-fin base; females generally with darker brown markings on body and more ornate fins, consisting of variable dark stripes or blotches on dorsal, anal, and pelvic fins (Ref. 116711).
Body shape (shape guide): elongated; Cross section: compressed.
This species occurs in moderately sloped areas (about 20 degrees) with mixed substratum (mud, sand, and gravel). Of the five individuals observed, three are solitary and a mixed sex pair (male holotype and female paratype) shared the same burrow. It is associated with an unidentified alpheid shrimp (Ref. 116711).
