Etymology: Hylopanchax: Greek, hylo, hyle = material, wood + Panchax, a word created by Meinken in 1932; paucisquamatus: The name is in reference to the low number of lateral line scales, from paucus = few and squamatus = scaled (Ref. 96960).

Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 0; Dorsal soft rays (total): 9 - 11; Anal spines: 0; Anal soft rays: 17 - 18; Vertebrae: 29 - 30. Diagnosis: Hylopanchax paucisquamatus is distinguished from all other known Hylopanchax species by a unique combination of morphological characters; by body-shape, it belongs to the group of more deep-bodied species in the genus (Ref. 96960). From the small, very slender H. moke it is distinguished by a deeper body, 26.1-27.2% of standard length vs. 16.3-20.2%; larger size, 22.0-26.1 mm standard length vs. 21.2 mm; a longer head, 26.7-29.6% of standard length vs. 17.9-23.7%; a deeper caudal peduncle, 11.8-12.2% of standard length vs. 7.7-11.3%; a longer dorsal-fin base, 11.7-13.1% of standard length vs. 5.9-9.9%; a lower number of mid-longitudinal scales, 19-21 vs. 23-26; a higher number of dorsal-fin rays, 9-11 vs. 6-7; and insertion of dorsal-fin above anal-fin ray 8 or 9 vs. 11-14 (Ref. 96960). From the slender H. stictopleuron and H. silvestris it is distinguished by a deeper body, 26.1-27.2% of standard length vs. 20.8-21.0% or 22.2-26.3% respectively; a slightly higher number of dorsal-fin rays, 9-11 vs. 6-8; a more anterior origin of dorsal-fin in relation to anal-fin, dorsal above anal-fin ray 8 or 9 vs. 12 or 13; and a lower number of mid-longitudinal scales, 19-21 vs. 24-25 (Ref. 96960). Hylopanchax paucisquamatus is distinguished from the two described deep-bodied species H. leki and H. ndeko by a longer predorsal distance, 68.8-70.7% of standard length vs. 61.0-67.8%; a narrower caudal peduncle and higher caudal peduncle ratio, 11.8-12.2% of standard length and 1.8-1.9 vs. 12.2-15.5% and 1.2-1.7; a shorter dorsal-fin base, 11.7-13.1% of standard length vs. 15.6-22.2%; a lower number of transverse scales, 15-16 vs. 18-22; a slightly lower number of dorsal-fin rays, 9-11 vs. 11-14; and a lower to slightly lower number of mid-longitudinal scales, 19-21 vs. 24-26 for H. ndeko and 21-23 for H. leki (Ref. 96960). It can also be distinguished from H. leki by a less deep body, 26.1-27.2% of standard length vs. 29.2-35.5%; and from H. ndeko by a longer caudal peduncle, 21.8-23.0% of standard length vs. 16.5-20.8% (Ref. 96960).
