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. votouro, H. megacephalus and H. macrops by the presence of light dots on all fins and the lateral and dorsal portions of body. H. meizospilos differs from H. chlorostictus and H. votouro by the much larger light markings (one large dot occupying one to three plates vs. one to three dots per plate) and from H. votouro by the larger orbit diameter (16.7-21.0% HL vs. 14.5-16.7% HL). H. meizospilos is distinguished from H. megacephalus and H. macrops by the area that light dots occupying each body plate (one large dot occupying one to three plates and skin between them vs. one large dot occupying only one body plate) (Ref. 54753).
与除了 H. chlorostictus , H. votouro 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. meizospilos 有别于 H. chlorostictus 与 H. votouro 藉由大很多的淡斑纹 (一大的点占领一对三个碟和一到三个每碟點比較) 與從 H. votouro 藉由比較大的眼窩直徑 (16.7-21.0% HL 和 14.5-16.7% HL 比較). H. meizospilos 被與 H. megacephalus 與 H. macrops 區分藉由區域哪一光點佔領每個身體碟 (一大的點佔領一對在他們之間的三個碟與皮膚 vs. 一大的點佔領只有一個屍體碟).(參考文獻 54753)

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01514 (0.00712 - 0.03216), b=2.97 (2.80 - 3.14), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
回复力 (Ref.
120179): 高度, 族群倍增时间少于 15个月 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
