Figure 2From: Oceanic dispersal barriers, adaptation and larval retention: an interdisciplinary assessment of potential factors maintaining a phylogeographic break between sister lineages of an African prawnRight first pereiopods (chelipeds) of Upogebia africana (Ortmann, 1894) mitochondrial DNA lineages. a, b, ovigerous female (cl 21 mm), Keurbooms (NHMW 23876), warm-temperate lineage; c, d, female (cl 19.8 mm), Mpenjati (NHMW 23870), subtropical lineage; a, c, lateral aspect; b, d, mesial aspect. Arrows point to a subdistal spine on the dorsal margin of the merus. The scale bar is 5 mm. Abbreviations: cl, carapace length; NHMW, Naturhistorisches Museum Wien.Back to article page
