Etymology: weitzmani: weiztmani is an eponym for Stanley H. Weiztman, in recognition of his many contributions to Neotropical ichthyology, particularly his work on the ichthyofauna of southern Brazil and the taxonomy of the genus Jenynsia.
Eponymy: Reverend Leonard Jenyns (1800–1893) was a clergyman and amateur naturalist. [...] Dr Stanley Howard Weitzman (1927–2017) was an American ichthyologist who was Research Scientist Emeritus, Division of Fishes, Department of Invertebrate Zoology, at the National Museum of Natural History, Smithsonian and a professor at George [...] (Ref. 128868), visit book page.

背棘 (總數) : 0; 背的軟條 (總數) : 10 - 11; 臀棘: 0; 臀鰭軟條: 9; 脊椎骨: 33. Possess a tubular gonopodium with shortened second, fourth and fifth anal fin rays, an enlarged seventh middle anal fin radial in males and females, and an elongate dorsoposterior process of the lacrimal. Branchiostegal rays: 5. Distinguished from other Plesiojenynsia by the following combination of characters: a single midlateral stripe without associated dorsolateral or ventrolateral stripes or blotches in adults; a terminal to slightly oblique mouth; fewer than 13 gillrakers; and absence of the first mandibular-canal pore.
持有一個管狀的生殖足有變短的第二個，第四的與第五個臀鰭棘條, 在雄性與雌性 , 與淚骨的一個細長後背突起中的一個增大的第七個中央的臀鰭動脈。 鰓條骨: 5. 在組合特徵之後與其他的 Plesiojenynsia 區分了藉由: 當成魚時的沒有相連的背外側或腹側的斑紋或斑塊的一條側面中央的斑紋; 一個端位到些微斜的嘴; 少於 13個鰓耙; 而且缺乏第一個顎骨管孔。
