Etymology: Monotocheirodon: Greek, monos = one + Greek, cheir = hand + Greek, odous = teeth (Ref. 45335); duda: Named after its type locality, collected mostly tributaries to the Duda River or captured in the Duda River itself (type locality). In Spanish, the epithet specific 'duda' means doubt, which also refers to its presumed placement into the genus Monotocheirodon, an assumption that needs further evaluation.

duri punggung lunak (Keseluruhan (total)) : 7; Sirip dubur lunak: 11 - 13; vertebrata, bertulang belakang: 36 - 37. The species is distinguished from all Stevardiinae species by the following set of characters: adult males with enlarged urogenital papilla (length about one-third to half of the first unbranched ray), which is in contact with the first anal-fin unbranched ray and a highly modified anal fin, with enlarged (anteroposteriorly) and distally elongated first and second branched anal-fin rays, forming a gonopodium-like structure; differs from its congenerspresence of an adipose fin (vs. absent); lateral line incomplete, pored scales not reaching the caudal fin (vs. lateral line complete); ascending process of the premaxilla dorsally directed (vs. strongly bent posteroventrally); snout longe, about a fourth of the head length (HL), between 23.1%- 30.0% of HL (vs. short snout, <20% of the HL) (Ref. 132484).

Cross section: compressed.
Occurs in shallow waters (< 1 m) of large-to-medium-size streams (< 70 m width) of clear-to-chalky silt colored waters of moderate flow running over sand, pebbles, and rock substrates. Stomach contents include mainly periphytic algae (Bacillariophyceae—Diatoms, Cyanophyceae, Zygnematophyceae, and Rhodophyceae) and rarely some macroinvertebrates (Diptera: Chironomidae larvae); sand grains were also abundant. Associated fish collected which are restricted to the Guaviare River basin include: Creagrutus maculosus, Chrysobrycon guahibo, Tyttocharax metae, Trichomycterus migrans and Schultzichthys gracilis; while other widely distributed species (in the Orinoco basin) were Astyanax metae, Hemibrycon metae, Hemigrammus barrigonae, Knodus cismontanus, Knodus deuterodonoides, Apteronotus galvisi, Cetopsorhamdia orinoco, Chaetostoma chimu, Characidium cf. boavistae, Characidium chupa, Parodon apolinari, Prochilodus mariae, Salminus iquitensis (Ref. 132484).
