“…All available illustrations of Coptostethus species were examined (Cobos , , ; Németh & Platia ; Platia , ; Platia & Kakiopoulos ) to identify variability in diagnostic characters in the bursa copulatrix sclerites. The following species had proximal sclerites moderate to broad (Figs 21,24), nearly symmetrical with a median groove and narrow (petiolate) base; distal sclerites fused and weakly sclerotized, and base of spermathecal gland duct surrounded by sclerotized ring: Coptostethus buci Németh & Platia, ; C. salvatoi Platia in Platia & Kakiopoulos, ; C. oromii (Cobos, ); C. machadoi (Cobos, ); C. vittatus (Lindberg, 1953); C. crassiusculus Wollaston, 1864; C. vestitus Lindberg, 1953; C. minutus Lindberg, 1953; C. canariensis Wollaston, 1858; C. hayeki (Cobos, ); C. obtusus Wollaston, 1864: 213; C. palmensis (Cobos, ); C. mateui (Cobos, ); C. obscurus Wollaston, 1864. The following species differed in that the distal sclerites did not have a petiole‐like base: C. globulicollis Wollaston, 1862; C. brunneipennis Wollaston, 1863; C. mendizabili (Cobos, ); C. arozarenai (Cobos, ), distal sclerites absent; C. fernandezi (Cobos, ); C. gomerensis (Cobos, ).…”
