B) Fe- male Aphvosemion elegans, commercial import (2006) from the Tshuapa River near Boende, not preserved. Photographed by H. Ott. tudinal series 28-30, with two scales posterior to hypur- al plate; seven transversal scales, 12 scales around cau- dal peduncle. Small dorsal fin with 8-9 fin rays, first dorsal fin ray inserts above 8-10th anal fin ray; anal fin with 13-15 rays; posterior dorsal and anal fin rays slightly elongated in males; caudal fin with 24-28 rays, with extensions on up- per and lower fin rays. X-ray images of three males from comparative materi- al (MRAC 37840-843) show 29-30 vertebrae and well separated upper and lower hypural bones. Live colouration. Males (Fig. 2A). Flanks golden to brown, with yellow to bluish-green iridescence. Most flank scales with a red dot. These dots are mainly situated at the posterior edge of the scales and usually form up to five parallel, interrupted stripes. Many populations have in ad- dition scales that have the red dots situated at the anteri- or edge of the scale. This causes, in combination with the adjacent scales above and below with red dots at the pos- terior edge, vertical narrow red bars. Three red streaks on opercle in an approximate 45° angle. One or two infra- buccal bands present on the lower jaw. Red dots under- neath the eye often united in a red streak. Pectoral fin translucent yellow to orange with a whitish or light yel- low edge; red dots present, sometimes concentrated near the yellow edge forming a red band. Anal fin light blue or light yellow, provided with many red dots and/or in- ter-radial red stripes, sometimes with a yellow or light blue margin. Dorsal fin predominantly dark red to almost black, with a narrow light band at the base and edged with a white, yellow, blue or nearly black ban
