A red body morph with reddish-orange body and brownish-red eyes is described in the terrestrial isopod, Venezillo evergladensis. The alternate, non-red morph, has a brown body and black eyes and either gray or orange antennae. Breeding results show three alleles, rg, ro and r at an autosomal locus control the variation. The dominance hierarchy is rg less than ro less that r; the genotypes, rg/rg, rg/ro, and rg/r are non-red, grey, ro/ro and ro/r are non-red, orange, and r/r are red. The gray antennae of non-red, gray individuals is variable in expression although still objectively recognized. The red body morph and its inheritance is paralleled in related species, while the antennal variation identifies a new allele. Sperm storage, exceeding a full year, and multiple matings in nature are documented.
在陆生等足类动物委内瑞拉埃弗格莱兹岛虫（Venezillo evergladensis）中，描述了一种红色体色形态，其身体呈红橙色，眼睛为棕红色。另一种非红色体色形态，身体为棕色，眼睛为黑色，触角要么是灰色要么是橙色。繁殖结果表明，一个常染色体位点上的三个等位基因rg、ro和r控制着这种变异。显性等级为rg小于ro小于r；基因型rg/rg、rg/ro和rg/r为非红色、灰色，ro/ro和ro/r为非红色、橙色，r/r为红色。非红色、灰色个体的灰色触角在表达上存在差异，尽管仍能被客观识别。红色体色形态及其遗传在相关物种中是平行的，而触角变异则识别出一个新的等位基因。有记录表明，精子储存时间超过一整年，且在自然环境中有多次交配现象。
