Etymology: Priapella: Taken from Priapus, the Greek, and Roman god of procreation in the mithology and also = a phallus; diminutive (Ref. 45335); chamulae: Named for the native population of the Chamula, who live in central Chiapas and on the Tabasco border, Mexico.

背的軟條 (總數) : 9 - 10; 臀鰭軟條: 10; 脊椎骨: 30 - 31. This species is a large sized species of Priapella (maximum length 4.8 cm SL). It is distinguished from its congeners by having the following characters: a membranous hook of the gonopodium ray 3 well developed and semicircularly bent (vs. slightly bent in P. bonita, P. compressa, P. intermedia and P. olmecae); subdistal plate-like membranous process on gonopodium ray 3 well developed (vs. not prominent in P. compressa and P. intermedia); spines of gonopodium ray 3 long and not numerous (vs. numerous and densely crowded in P. compressa and P. intermedia) and short and not densely crowed in P. olmecae); distal part of gonopodium ray 4p slightly bent (vs. strongly bent in P. bonita, P. compressa, P. intermedia and P. olmecae). This species is also distinguished by having a short gonopodium; frequency distribution of SL/GL radius 3.30-3.50 (vs. 2.60-2.75 in P. olmecae, 3.00-3.20 in P. compressa, 2.60 in P. bonita and 3.50-3.60 in P. intermedia; gill rakers 10-12 (vs. 15-16 in P. bonita, 120-13 in P. compressa, 12-14 in P. compressa; dorsal-fin rays 9 (vs. 8 in P. bonita, 10 in P. compressa (Ref. 57748).
這種是一個 Priapella 的巨大體型種。 (最大的長度 4.8 公分 SL) 它是與它的同類區分藉著具有下列的特徵: 生殖足鰭條的一個膜狀鉤 3個發展良好的而且半圓地彎曲;(vs. 些微地在 P. bonita ， P. compressa ， P. 媒介物 與 P. olmecae 彎曲) 在生殖足鰭條上的子末梢部的板狀膜狀的突起 3個發展良好的;(vs. 不是突出在 P. compressa 與 P. 媒介物 中) 生殖足鰭條的棘 3 長的而不是很多的 (vs. 很多的而且濃密地在 P. compressa 與 P. 媒介物 中擁擠了) 而短的而不是濃密地啼叫在 P. olmecae); 生殖足鰭條 4p 的末梢部部份些微地彎曲。 (vs. 強烈地在 P. bonita ， P. compressa ， P. 媒介物 與 P. olmecae 彎曲) 這種也被藉著區別有一個短的生殖足; SL/GL 半徑 3.30-3.50 的度數分析 (vs.2.60-2.75 在 P. olmecae 中, 3.00-3.20 在 P. compressa 中, 2.60 在 中 P. bonita 與 3.50-3.60 在 P. 媒介物 ; 鰓耙 10-12(vs.15-16 在 P. bonita 中, 120-13 在 P. compressa 中, 在 P. compressa 中的 12-14; 背鰭鰭條 9(vs.8 在 P. bonita 中, 10 在 P. compressa 中.(參考文獻 57748)
Collected from a small brook, about 0.5 to 1 m wide, that flows into a tributary to the río Tacotalpa, close to a bridge, a few hundred meters on an unpaved road that branches off into northeasterly direction from the main road from Tapijulapa to Jamapa between the small settlements of Zunu y Patastal and Madrigal (Cuarta sección). At the time of collection, at late afternoon the water had a temperature of 26 °C, a conductivity of 360 mS, pH 8.0, and total hardness of 10-15. The water was crystal clear and fast flowing with no aquatic vegetation. The substratum consisted mainly of gravel and sand. The brook flows in a deep indentation and is fully shadowed by the vegetation. Associated poeciliid fishes were Pseudoxiphophorus bimaculatus, Gambusia sp., Heterophallus milleri, Poecilia mexicana and a characid, Astyanax mexicanus (Ref. 57748).
採集自一條小的小溪 , 大約 0.5 到 1 公尺寬., 那流入中一 rio Tacotalpa,接近一座橋的支流, 一些百公尺在一條沒有鋪石磚的道路上哪一分支外海的從 Tapijulapa 到 Jamapa 進入東北風方向從幹線道路之內在 Zunu y Patastal 與情歌 (Cuarta seccion) 的小沈降之間. 採集時, 在水 26 °C 發燒的午後接近傍晚, 360 的導電率 10-15 的 mS ，酸鹼度 8.0 與總堅硬. 水是透明清澈而快速的流動沒有水生植物。 下層土壤主要地礫石與沙子組成.。 小溪在一個深的壓痕中流動而且完全被植物遮蔽。 相連的胎鱂科魚類魚是 Pseudoxiphophorus bimaculatus ， Gambusia sp. ， Heterophallus milleri, 短鰭花鱂〔短帆鱂〕〔Poecilia mexicana〕 與一個脂鯉科魚類, Astyanax mexicanus.(參考文獻 57748)
