简单描述
型态特徵 | 形态测量图
背棘 (总数): 2; 背的软条 (总数): 7; 臀棘 1; 臀鳍软条: 4. Distinguished from all other species of Hemiancistrus except H. chlorostictus, H. meizospilos, H. megacephalus and H. macrops by the presence of light dots on all fins and the lateral and dorsal portions of body. H. votouro differs from H. chlorostictus by having more premaxillary teeth (61-79 vs. 30-54), larger adipose-fin spine (9.0-10.4% SL vs. 5.8-8.0% SL), deeper caudal peduncle (11.0-11.8% SL vs. 9.6-10.4% SL), larger pectoral fin (36.2-41.3% SL vs. 30.6-35.4% SL); larger exposed portion of cleithrum (11.2-12.7% SL vs. 9.3-10.6% SL), narrower body at dorsal-fin origin (17.9-19.8% SL vs. 19.9-25.3% SL) and first anal-fin pterygiophore not exposed (vs. exposed). H. votouro differs from H. meizospilos by the smaller orbit diameter (14.5-16.7% HL vs. 16.7-21.0% HL) and much smaller light markings (one to three dots per plate vs. one large dot occupying one to three plates and skin between them). H. votouro is distinguished from H. megacephalus and H. macrops by the number of the light markings per body plate (one to three small dots per plate vs. only one large dot on each body plate) (Ref. 54753).
与除了 H. chlorostictus ， H. meizospilos 以外的所有其他种的 Hemiancistrus 区分了, H. megacephalus 与 H. macrops 藉由在所有的鳍与身体的侧面与背部部分上有淡的点。 H. votouro 有别于 H. chlorostictus 借着具有更多的上颌骨前的齿 (61-79 vs.30-54), 较大的脂鳍棘 ，较深的尾柄 (11.0-11.8% SL vs.9.6-10.4% SL)0, 較大的胸鰭;(36.2-41.3% SL vs.30.6-35.4% SL) 匙骨 (11.2-12.7% SL 和 9.3-10.6% SL 比較) 的比較大的裸露部分 , 在背鰭起點 (17.9-19.8% SL 和 19.9-25.3% SL 比較) 的較狹窄的身體與第一個臀鰭支鰭骨不暴露出來.(vs. 裸露的) H. votouro 有別於 H. meizospilos 藉由比較小的眼窩直徑 (14.5-16.7% HL 和 16.7-21.0% HL 比較) 與較小淡的斑紋。 (一對三個每碟點和一大的點佔領比較他對在他們之間的三個碟與皮膚) H. votouro 被與 H. megacephalus 與 H. macrops 區分藉由淡每身體碟 斑紋三的數字。 (參考文獻 54753)
Facultative air-breathing in the genus (Ref. 126274); Found in a 2-5 m wide stream, with rocky and sandy bottom, small rapids separated by pools and marginal vegetation moderately preserved (Ref. 54753).
