Notes. Oryzaephilus gibbosus is widespread in Africa but has not previously been recorded from Socotra. In the past it was found on East African coconuts and coconut shell (AITKEN 1965) imported to the United Kingdom. It has also been found on other oilseeds, sifted from compost, and caught in a soil trap (HALSTEAD 1980). Some notes on characters for distinguishing O. gibbosus and O. socotraensis sp. nov. are included in the differential diagnosis for the latter species. In addition, O. gibbosus males have a spine on the metafemora, as well as the other secondary sexual characters of the hind legs. The typical form of the parameres and median lobe of this species is illustrated in Fig. 7. For additional line illustrations of O. gibbosus and its genitalia, see HALSTEAD (1980, 1993).
