description

Description. Dorsal-fin rays VI + I, 9 – 10; anal-fin rays I, 8 – 9; unbranched pectoral-fin rays 16, lateral scale rows 23 – 24. The six specimens for which we have live color records are in poor condition and counts were not possible for several of them. Therefore, the range of counts given here will not represent the true range of variation and pelvic-fin information was not possible. The ranges given by Lachner and Karnella (1980), although based on at least two species, are probably closer to the range of variation for this species. Measurements (based on five specimens). Standard length 14.2 – 20.9 mm; head length (31.7 – 36.5, 33.3); origin of first dorsal fin (31.0 – 39.3, 35.0); origin of second dorsal fin (53.4 – 63.8, 58.5); origin of anal fin (58.5 – 66.7, 62.2); caudal-peduncle length (21.5 – 21.7, 21.6); caudal-peduncle depth (13.4 – 15.5, 14.4); body depth (22.5 – 29.6, 26.3); eye diameter (10.7 – 13.0, 11.8); snout length (5.2 – 7.0, 6.3). Color in preservative (from BPBM 33614). Background color of head and body pale yellowish. A light brown band overlaid with a peppering of tiny brown dots on lower body, slightly above midline, from behind eye posterior to caudal-

diagnosis

Diagnosis. The following combination of characters distinguish E. nigriventris from congeners: A red band on entire lower body from head back to caudal-fin base where it grades into black ending in an asymmetrical spot that angles down sharply towards the ventral portion of the caudal fin (Fig. 19); pectoral-fin base peppered with small black dots, more intense dorsally; cephalic sensory pore system lacking the PITO and IT pores and the AITO pore enlarged; dorsal / anal fin-ray formula 9 / 8. Pectoral-fin rays simple; spinous dorsal elongate or filamentous in both sexes. Genital papilla nonfimbriate. In life the ventral red band is bordered dorsally by a bright white band that runs from the top of the head back to the caudal fin where it curves down following the angled black spot.
