Etymology: Haplochromis: Greek, Haploos = single + Greek, chromis = a fish, perhaps a perch (Ref. 45335)sphex: From the Greek 'σϕήξ', wasp, referring to the colouration of males; like the wasp, males of this species are typically yellow with black stripes (Ref. 85523).

Ryggkotor: 29 - 31. Diagnosis: Haplochromis sphex is a small sized (less than 9 cm standard length), slender (body depth less than 32% of standard length) micrognathic species, with mainly bicuspid teeth in the oral jaws; dorsal head profile straight to moderately curved (Ref. 85523). The colouration of the sexually active males is yellow with blackish longitudinal, interrupted bands and vertical bars, producing a so-called 'chess board pattern'; this pattern also occurs in several oral shelling molluscivores, insectivores and algae scrapers, but these species generally are larger, have a deeper body, have a strongly curved dorsal head profile and a lower jaw length/width ratio of less than 1.5, whereas in Haplochromis sphex it ranges from 1.5 to 2.7 (Ref. 85523). It differs from other small species with a 'chess board pattern', H. bwathondii and H. sauvagei, by its shallower body; sexually active males of H. sauvagei generally have a more distinct 'chess board pattern' than H. sphex; in contrast to H. sphex, sexually active males of both H. bwathondii and H. sauvagei develop a red chest and belly; the colouration of females and quiescent males of H. sauvagei is rather similar to that of sexually active males of H. sphex (Ref. 85523).
Body shape (shape guide): fusiform / normal.

Biologi     Ordlista (t.ex. epibenthic)

Found in waters up to a depth of 10 m both over sand and mud (Ref. 85523). It fed mainly on phytoplankton (Cyanophyta and Aulacoseira) and occasionally on copepods (Ref. 85523). This species is a female mouth brooder (Ref. 85523).
