Etymology: petnehazyi: The species epithet is given in honour of Gábor Petneházy who accompanied Béla Nagy collecting killifishes during several field trips in Africa, including the one in Democratic Republic of Congo in 2016, and collected the species at the type locality during the second field trip; a noun in genitive case (Ref. 122040).

Краткое описание
определительные ключи | морфология | морфометрия
колючие лучи спинного плавника (общее число) : 0; членистые (мягкие) лучи спинного плавника (общее число) : 8 - 10; колючие лучи анального плавника: 0; членистые (мягкие) лучи анального плавника: 14 - 16. Diagnosis: Micropanchax petnehazyi is distinguished from all other Micropanchax species, with the exception of M. hutereaui, by the combination of following characters in male colouration: dark transverse markings on the median fins; reticulate markings on the side; as well as the structure of the cephalic sensory system in both sexes characterised by a supraorbital canal composed of two short, discontinuous grooves containing exposed neuromasts; postorbital and preopercular sensory systems tubular with pores (Ref. 122040). Furthermore, M. petnehazyi is distinguished from M. hutereaui by the following unique combination of characters in males: dorsal and anal fins with faint brown stripes perpendicular to fin rays vs. curved stripes in M. hutereaui; anal fin with a faint brown margin and without a light submarginal band vs. with dark brown margin and with light submarginal band; caudal fin with irregular vertical markings forming a reticulate pattern vs. narrow vertical bands; as well as, in both sexes, preorbital sensory system in a shallow canal with three exposed neuromasts vs. tubular with three pores; mandibular sensory system in open groove with small exposed neuromasts vs. tubular with pores; smaller body depth at pelvic-fin origin 25.3-28.7% of standard length vs. 30.0-32.3%; smaller interorbital width 34-40% of standard length vs. 47-51%; larger postorbital length 45-46% of head length vs. 38-43%; smaller suborbital depth 11-14% of head length vs. 21-25%; and larger caudal peduncle length 1.4 times of its depth vs. 1.0-1.1 (Ref. 122040).
Body shape (shape guide): fusiform / normal; Cross section: compressed.
Currently known from ephemeral pools of the Tshipokokolo system (Ref. 122040). The water of the habitat was transparent with the bottom of the pool well visible although the water was slightly brownish in colour (Ref. 22040).
