Aphyosemion Mandoroense

📖 Overview

Aphyosemion Mandoroense (Aphyosemion mandoroense), first described by van der Zee, Walsh, Boukaka Mikembi, Jonker, Alexandre & Sonnenberg, 2018 is a tiny fish in the family Nothobranchiidae (order Cyprinodontiformes). Adults typically reach 3.70 cm in maximum length. It inhabits freshwater systems including rivers, streams, and lakes. It occurs in Subtropical waters. It is broadly omnivorous, taking invertebrates, plant matter, and detritus.

🔬 Taxonomy

🐟 Physical Description

Dorsal spines (total): 0; Dorsal soft rays (total): 11 - 12; Anal spines: 0; Anal soft rays: 16 - 17. Diagnosis: Males of Aphyosemion mandoroense are distinguished from all other Aphyosemion species by the lack of red pigmentation on its fins, except for the posterior margin of the dorsal fin in some specimens; DNA data and male colour pattern place it into the A. coeleste group . Aphyosemion mandorense can be distinguished by its diagnostic male colouration pattern from all other species of the A. coeleste group by the nearly complete absence of red in unpaired fins, versus red margins or sub-marginal stripes in all other species except A. ocellatum, which shows faint red areas in the unpaired fin centre of some individuals; Aphyosemion mandoroense is distinguished from all other species except A. ocellatum and A. passaroi by its dark grey to black margins of unpaired fins; it is distinguished from A. passaroi by the nearly complete absence of red in fins, blue side and opercle vs. basal broad red stripe in anal fin and orange to brownish or pinkish side and opercule . Aphyosemion mandoroense is distinguished from the A. ocellatum populations with blue sides by the three or four rows of red dots on anterior side, the light blue opercle vs. a dark red blotch posterior to operculum, and yellow or orange operculum, and from those with a more brownish to orange body colour by the blue side colour, absence of dark red blotch posterior to operculum and blue operculum; Aphyosemion ocellatum in addition has darker and broader fin margins on pelvic, anal, dorsal, and upper and lower caudal fin . The superficially most similar A. citrineipinnis and A. ocellatum also have a reduced red pigmentation on fins, but usually at least traces of a red stripe at the base of the anal fin is present; base of anal fin in A. citrineipinnis blue, central to distal part yellow vs. completely yellow in A. mandoroense; unpaired fin margins in A. mandoroense dark grey to black vs. no or very narrow dark fin margin in A. citrineipinnis; many A. citrineipinnis populations usually show a prominent 'wound mark', a group of dark red scales just behind the operculum, that is always absent in A. mandoroense, which shows three or four rows of red dots on the anterior side above the pelvic fin; the operculum is light blue in A. mandoroense vs. yellow to orange in A. citrineipinnis; in A. mandoroense, the yellow colour of the caudal fin is extended in the dorsal and ventral edge of the caudal peduncle, vs. no yellow on caudal peduncle in A. citrineipinnis; in A. mandoroense, the dorsal fin inserts more posteriorly than in A. citrineipinnis .Cross section: oval.
