Etymology: bonita: Named for its type locality, Baía Bonita; noun in apposition.
Eponymy: Dr William J Moenkhaus (1871–1947) was an American geneticist and ichthyologist who became Professor of Physiology at Indiana University Medical School (1904–1941), where he was Eigenmann’s colleague. [...] (Ref. 128868), visit book page.

; 淡水 大洋性; 深度上下限 0 - 1 m (Ref. 51265). 熱帶
South America: known only from its type locality in the upper Rio Miranda, Brazil.

Maturity: Lm ? range ? - ? cm
Max length : 8.5 cm SL 雄魚/尚未辨別雌雄; (Ref. 122736); 最大體重: 7.70 g (Ref. 122736)
背的軟條 (總數) : 11. This species differs from other congeners, except intermedia and dichroura by the following combination of characters: presence of a black posterior margin on each caudal-fin lobe, and presence of a black lozenge-shaped pigment blotch on the caudal peduncle that extends to the posterior limit of the median caudal-fin rays; the short 7 gill rakers on the upper limb of the first gill arch distinguish bonita from the 2 similar species that possess 10 elongate gill rakers on the upper limb an d18 on the lower limb of the first gill arch (Ref. 51265).
這種與其他同類不同, 除了 媒介物 與 dichroura 以外藉由跟隨組合特徵: 有在每個尾鰭葉上的一個黑色的後緣, 而且有一個黑色的菱形-在延伸到中央尾鰭鰭條的後面的限制的尾梗上的形狀有顏色斑塊; 在第一個鰓弓的上邊緣上的短人 7個鰓耙區別 bonita 從在第一個鰓弓的下面肢翼上在上邊緣上持有 10個細長的鰓耙 d 18 的 2個相似的種。 (參考文獻 51265)
Collected in marginal backwaters with low current speeds (about 0.1 m/sec) in up to 1 meter depth. Occurs primarily near the water surface, swimming in schools up to 10-30 individuals. Stomach contents and observations indicate that this species feeds mainly on terrestrial insects (dipterans and coleopterans) from the surrounding riparian forest. The insects are captured via surface picking and drift feeding (Ref. 51265).
在邊緣的洄水區中的向上到 1 公尺深度中收集了水流量小的地方速度 (大約 0.1 公尺/秒) 。 主要地在水面的附近生存,在魚群向上到 10-30個個體中游泳。 胃內含物與觀察指出這種主要捕食陸棲的昆蟲 (雙翅類昆蟲與鞘翅目) 從周圍的河岸森林。 昆蟲經由表面的採集與漂流物進食被捕獲。 (參考文獻 51265)
