背的軟條 (總數) : 13 - 15; 脊椎骨: 42 - 45. Hoplias microlepis is distinguished from all congeners, except species of H. malabaricus group, by the the shape of the dentaries abruptly converging towards the mandibular symphysis (vs. dentaries parallel and only gently converging towards the mandibular symphysis) and by having tooth plates on tongue (vs. absence of tooth plates on tongue). H. microlepis can be separated from H. brasiliensis and H. curupira by having 43-47 scales on lateral line (vs. 38-43 and 34-39, respectively), and from H. australis and H. lacerdae by having 4 pores of the laterosensory system along the ventral surface of dentary (vs. always 5 and 6-8 respectively). It differs from H. aimara by having accessory ectopterygoid and by lacking vertically elongate dark spot on the opercular membrane (vs. absence of accessory ectopterygoid and presence of dark spot). It can be diagnosed from the other members of the H. malabaricus species group by having more circumpeduncular scales (22-24, usually 24 vs. 18-20, usually 20) (Ref. 96873).
Inhabits rivers (Ref. 96873). Collected in creeks and swamps in areas of little or no current on sand and mud bottoms. Lives between 20 and 40 m elevation. Piscivorous (Ref. 36880). Reported to reach 50.0 cm TL (Ref. 9585).
在沙與泥底部上的少或沒有水流的區域中的小溪與沼澤中收集了。 生活在 20 與 40 公尺海拔之間。 以魚為食的.(參考文獻 36880) 棲息於河。
