Etymology: Ptychochromoides: Greek, ptyx, ptychos = fold + Greek, chromis = a fish, perhaps a perch (Ref. 45335); vondrozo: Named for the nearest village to the type locality that is depicted on readily available maps; the epithet vondrozo is used as a noun in apposition (Ref. 39915).

背棘 (总数) : 13 - 15; 背的软条 (总数) : 10 - 13; 臀棘: 3; 臀鳍软条: 9 - 10; 脊椎骨: 29 - 31. Diagnosis: Ptychochromoides vondrozo is distinguished from congeners by the lack of a prominent adipose occipital hump, even in large adults and regardless of sex (Ref. 39915). In life, Ptychochromoides vondrozo is diagnosed by a vivid golden-olive ground colouration in combination with an irregular, brownish to black, blotchy and speckled lateral pigmentation pattern (Ref. 39915). It is further distinguished from its sister taxon, Ptychochromoides betsileanus by possession of a shallower caudal peduncle, 12.9-14.8% of standard length vs. 15.8-18.1%; a noticeably convex lateral snout outline with conspicuous premaxillary pedicel prominence; and a higher modal vertebral count, 30 vs. 29 (Ref. 39915). It is distinguished from Ptychochromoides katria by a larger adult size, exceeding 200 mm standard length; a mottled and blotchy overall pigmentation pattern vs. solid golden-brown base body colouration, with two wide, black vertical bars on the flanks; a greater number of ceratobranchial gill rakers, 10-12 vs. 8-9; the absence of a hypertrophied cephalic latero-sensory canal system on the lower jaw, preopercle, and neurocranium; and the presence of cycloid scales on the chest and belly vs. cycloid scales restricted to the extreme antero-ventral margin of the chest (Ref. 39915).
与同类区分的一个 Ptychochromoides 藉由没有一个突出的脂肪后头骨隆起。 (参考文献 39915) 尾梗很浅, 狭窄的与延长 (12.9-14.8% SL).(参考文献 39915) 活着时, 一生动的金-组合的橄榄色土地的颜色有一个不规则的，褐色或黑色的，和到处有污点而有斑点的侧面颜色图案.(参考文献 39915)
Found in the deep, seasonally turbid, and moderate to fast-flowing rivers in the immediate vicinity of Vevembe (Ref. 39915). These habitats are characterized by a relatively sandy substrate, with regions of small to large rocks and boulders, where there are areas of relatively still water and deep pools, in addition to swift flowing water (Ref. 39915). Specimens were captured with hook and line using Odonata larvae (Ref. 39915).
在 Vevembe 的紧邻区域中已知来自深的，季节性浑浊，与和缓到快速-流动的河了。 它出现它被局限于较大的河与他们的支流。 这些栖息地特徵为一相当砂质底部, 藉由小型到大型岩石与大圆石的区域.(参考文献 39915) 标本被用使用蜻蛉仔鱼的一支钓捕获。 (参考文献 39915)
