Etymology: Petrocephalus: Latin, petra = stone + Greek, kephale = head (Ref. 45335).
Eponymy: Nicolas Bové (1802–1842) was a Luxembourg gardener, botanist and collector. [...] (Ref. 128868), visit book page.

Madurez: Lm 6.8 range ? - ? cm
Max length : 11.5 cm SL macho / no sexado; (Ref. 123661); peso máximo publicado: 30.00 g (Ref. 123661); edad máxima reportada: 2.50 años (Ref. 2749)
Espinas dorsales (total) : 0; Radios blandos dorsales (total) : 21 - 28; Espinas anales: 0; Radios blandos anales: 27 - 35. body depth 2.9-3.7 x SL, anal base 3.2-4.7 x SL, caudal peduncle height 13.3-19.3 x SL. Eye diameter 2.7-4.6 x head length. Uniformly brilliant silver color, sometimes grayish or brownish.
Body shape (shape guide): fusiform / normal; Cross section: compressed.
Affinities: P. pellegrini. Generates electric organ discharge (EOD) of short duration that seems to correlate with aggregative behavior of the species (Ref. 14060; 10601). EOD temporal pattern cues have been shown to play a role in species recognition for P. bovei (Ref. 10600). A ratio measure between olfactory and visual receptor areas suggests that this species relies more on visual than olfactory information (Ref. 10839). A fractional spawner (Ref. 10605; 10606).
