Katreus dimidia Holland 1896

Katreus dimidia (Holland) (Fig. 17, $ genitalia [f. hollandi])
Acallopistes dimidia Holland, 1896: 97; pi. 5, fig. 7 (Gabon).
= Ortholexis hollandi H. H. Druce, 1909: 407 (Cameroon).
=Katreus dimida i. drucei Evans, 1937: 17 (Cameroon).
= Katreus dimidia f. karschi Evans, 1937: 17 (Casualalla, N. Angola).
All the above names are retained by Evans (1937: 17) as "forms", but they are so diverse as to cast doubt upon their conspecificity. Available material is insufficient to determine the true identity of these names, but Evans claims the male genitalia of all but typical dimidia (which he did not see) are alike. The Carnegie Museum Collection contains only two males of "hollandi", a female of "drucei", and a female of "karschi"; there are no specimens of the nominate form at hand. At present it is desirable to retain the "forms" of Evans, whatever their systematic validity, to call attention to the variability present in material of "dimidia", though no further systematic decisions can be rendered upon them at this time. In its various "forms" dimidia is recorded from Cameroon, Angola, and the Congo (Evans, 1937: 17).
