Etymology: Hemiodus: Greek, hemi = half + Greek, odous = teeth (Ref. 45335); langeanii: Named for Dr. Francisco Langeani, for his highly relevant contributions to the knowledge of hemiodontid fishes.
Eponymy: Dr Francisco Langeani Neto is a Brazilian ichthyologist who specialises in Neotropical fish at Universidade Estadual Paulista, Instituto de Biociências, Letras e Ciências Exatas, where he is an adjunct professor. [...] (Ref. 128868), visit book page.

မိ်ဳးပြားရန္အရြယ္ေရာက္ျပီ: Lm ?  range ? - ? cm
Max length : 13.6 cm SL အထီး/လိြင္ခြဲျခားျခင္းမျပဳနုိင္ေသာ; (Ref. 91067)
ေက်ာဘက္တြင္ရွိေသာ ေရယက္၌ပါေသာ အမွ်င္မ်ား (စုစုေပါင္း) : 11 - 12; စအိုနားတြင္ရွိျပီး နူးညံ့ေသာေရယက္အမွ်င္မ်ား: 11 - 13; ေက်ာရိုးမ်ား: 36. Distinguished from other species of Hemiodus by its high body (27.1-35.3%, average 32.3% SL vs. 18.8-28.5% in remaining species). Other diagnostic characters include the following: presence of a large lateral dark spot that is equal to, or greater than, the eye diameter (vs. smaller in remaining species except for Hemiodus microlepis); absence of conspicuous lateral stripe or transverse bands; 68-74 scales on lateral line (vs. 94-123 in Hemiodus argenteus, 124-148 in Hemiodus microlepis, 86-99 in Hemiodus orthonops and 77-92 in Hemiodus parnaguae). Differs from Hemiodus unimaculatus (which overlaps in the number of lateral line scales) by having 9-10 scales between the lateral line and the pelvic fin origin (vs. 4-7), which are similar sized above and below lateral line (vs. scales larger bellow the lateral line in Hemiodus unimaculatus) (Ref. 91067).
Found in slow-flowing stretches of the rio Amana and igarapé Porquinho (1.0-2.5 m deep) and in artificial ponds (4.0-5.0 m deep and 40-70 m in diameter) resulting from gold-mining activities. The Rio Amana and its tributaries are characterized by clear water (not stained by humic acids) but turbid due to excess of fine suspended solids (clay) as a result of mining activities along river margins and/or bottom such as dredging (Ref. 91067).
