Baker 1999: 24, fig. 1-2; Meier and Baker 2002: 326. Type series. Indonesia: holotype “ Fæm. ” ♀ (head and abdomen lost, Fig. 136), Makessar, Celebes, on label Macassar, Celebes, A. R. Wallace, ex coll. Saunders 684 [Makassar, Sulawesi, Indonesia, ~ 5°12'31"S, 119°27'1"E, ~ 5 m] (NHMUK). The type of D. cothurnata appears lost. Bigot only indicated Célèbes [Sulawesi, Indonesia]. Distribution. Only Sulawesi can, at present, be considered as the area for S. detrahens. Sphyracephala specimens from countries as far apart as Malaysia, Japan, and the Solomon Islands have been identified as S. detrahens. However, at least part of these identifications appears doubtful and more study of genitalia or molecular studies are required. Although S. detrahens and S. cothurnata appear distinct synonyms, it is possible that at least on the small islands near Sulawesi an additional species occurs. Illustrations. A set of photographs (Figs 134 – 141) of habitus, head, thorax, wing, fore femur, and abdomen is presented.
