Etymology: Hylopanchax: Greek, hylo, hyle = material, wood + Panchax, a word created by Meinken in 1932; multisquamatus: The name is derived from the Latin term multi meaning 'many' and squama meaning 'scale' and refers to the high number in mid-longitudinal scales (Ref. 123864).

Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 0; Raggi dorsali molli (totale) : 7 - 8; Spine anali: 0; Raggi anali molli: 13 - 16; Vertebre: 31 - 32. Diagnosis: Hylopanchax multisquamatus is distinguished from its congeners by the presence of more scales along the mid-longitudinal series of scales, 27-30 vs. 19-26, and by the possession of an anterior/posterior flank scale height ration, 140%-150% vs. 170%-220% (Ref. 123864). It is distinguished from H. stictopleuron by the number of scales in transversal row, 6 vs. 5; in addition, H. multisquamatus is distinguished from congeners except Hylopanchax thysi, by the presence of a hyaline urogenital male papilla with small black spots in preserved specimens vs. black, and by the presence of a dark-brown reticulate pattern on the flank of both males and females vs. absence or less-conspicuous pattern; finally, H. multisquamatus is distinguished from H. thysi by the presence of 11-12 pectoral-fin rays vs. 13-14, a male caudal peduncle depth-length ratio between 40-45% vs. 53-59%, a body depth of 20.0-23.7% of standard length vs. 25.2-27.8%, a female predorsal length between 66.0-74.8% of standard length vs. 62.0-64.0%, and a female prepelvic length of 42.1-45.1% of standard length vs. 33.7-38.0% (Ref. 123864).
Cross section: compressed.
This species inhabits shallow creeks inside dense forest areas (Ref. 123864).
