Anemesia pococki sp. nov. generally resembles a paler coloured version of A. birulai . However, it differs from the latter species by the aspinose cymbium and a less tapering embolus in males ( Figs 175 View Figs 173–187 , 193– 194 View Figs 188–196 ; cf Figs 173 View Figs 173–187 , 188–190 View Figs 188–196 ), as well as by less sclerotised and more diverged receptacles in females ( Figs 228–229 View Figs 224–244 ; cf Figs 224–227 View Figs 224–244 ).


The specific name is a patronym in honor of Dr Reginald I. Pocock, the noted British arachnologist (1863–1947), who provided and published many studies on the Mygalomorphae ; he described, in particular, both the genus Anemesia in 1895 and its type species a few years earlier (1889).
