Etymology: Pseudotanganikallabes: From the Greek pseudo (ψευδής), meaning lying or false and the genus Tanganikallabes, in reference to the superficial resemblance between these two genera; prognatha: The specific epithet is derived from the prefix pro, in this case meaning anterior to and the Greek gnathos (γνάθος), meaning jaw, in reference to the distinctive protrusion of the lower jaw of this species; gender: feminine (Ref. 116742).

Kurzbeschreibung
Bestimmungsschlüssel | Morphologie | Morphometrie
Rückenflossenstacheln (insgesamt) : 0; Rückenflossenweichstrahlen (insgesamt) : 61 - 67; Afterflossenstacheln: 0; Afterflossenweichstrahlen: 53 - 58. Diagnosis: Among clariids, Pseudotanganikallabes prognatha most closely resembles young Tanganikallabes specimens in external appearance, but can be easily distinguished from members of this genus by a number of characters: the number of post-Weberian vertebral elements in P. prognatha is lower than that of Tanganikallabes, 50-51 vs. 53-61; it further differs from T. mortiauxi by its relative shorter prepelvic length, 35.8-39.7% of standard length vs. 39.7-44.4%, and pre-anal length, 43.2-46.7% of standard length vs. 47.1-51.7%, shallower body, body depth at anus 9.1-10.3% of standard length vs. 12.3-17.2%, shorter snout, 4.1-5.5% of standard length vs. 5.7-8.2%, and lower total number of dorsal and anal-fin rays, 61-67 vs. 72-81 dorsal rays and 53-58 vs. 58-65 anal rays; it can be further separated from T. alboperca by its relative shallower body, body depth at anus 9.1-10.3% of standard length vs. 11.7-14.6%, and from T. stewarti by its relatively greater predorsal length, 31.4-34.4% of standard length vs. 28.0-31.2%, shorter dorsal fin, 66.7-69.7% of standard length vs. 70.3-75.4%, and lower total number of dorsal and anal-fin rays, 61-67 vs. 72-79 dorsal rays and 53-58 vs. 63-69 anal rays (Ref. 116742).
