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

Environment / Climate / Range Ecology

Freshwater; benthopelagic; depth range ? - 10 m (Ref. 85523).   Tropical, preferred ?

Short description Morphology | Morphometrics

Vertebrae: 29 - 31. Haplochromis sphex is a small sized (<9 cm SL), slender 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' (Ref. 85523). 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; it differs from other small species with a 'chess board pattern', Haplochromis bwathondii and H. sauvagei, by its shallower body (Ref. 85523).

Biology     Glossary (e.g. epibenthic)

Occurs in waters up to a depth of 10 m both over sand and mud. Feeds mainly on phytoplankton and occasionally on copepods. A female mouth brooder (Ref. 85523).

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01514 (0.00709 - 0.03231), b=2.97 (2.80 - 3.14), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.3   ±0.4 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months ().
Vulnerability (Ref. 59153):  Low vulnerability (12 of 100) .
