Zetheumenidion pulchripenne ( CaMerOn, 1910)

( Figs. 11 , 12 )

Eumenes pulchripennis Cameron 1910: 158 , 160 (key), ♀ —[ South Africa] “ Kranspoort ” (NHRS).

Diagnosis. Dark species with black and dark red pattern and blackish wings with purple reflections ( Fig. 11A ), readily distinguished from the other species by the pronotal carina depressed in the median third, the anterior margin of pronotum medially concave and laterally projecting and the punctures on mesepisternum very coarse with interspaces reduced to narrow sharp ridges.

Material examined. NAMIBIA: SW. Africa, Grotfontein , 1903, leg. Volkmann, 1♀ ( MSNVE, paralectotype of Eumenes femoratus ) ; SOUTH AFRICA: Pretoria , 2.X.1933, leg. G. van Son, 1♂ ( MSNVE) ; ZIMBABWE: S. Rhodesia, Bulawayo, 11.V.1927, leg. R.H.R. Stevenson, 1♂ ( MSVI) ; S. Rhodesia, Khami , 20.III.1960, leg. C. Jacot-Guillarmod, 1♀ ( MSVI) ; S. Rhodesia, Umtali , 25.X.1943, 1♀ ( MSNVE) .

Distribution. Namibia; South Africa: Gauteng, Limpopo?, Mpumalanga; Zimbabwe ( Cameron 1910; Giordani Soika 1944 [as E. paeneplanus ], 1983 [part]; von Schulthess 1910 [part, under Z. femoratum ]) ( Fig. 13 ).

Notes. Carpenter et al. (2010) reported Zetheumenidion pulchripenne as present in Botswana, citing Giordani Soika (1983) as source of this occurrence. In fact, the specimen from Botswana cited by Giordani Soika (1983) is the lectotype of Zetheumenidion femoratum , not a specimen of Z. pulchripenne . Although the presence in Botswana is highly probable given the known distribution of the species, we currently have no data regarding the presence in that country. Most of the specimens cited by Giordani Soika (1983) were re-examined and found belonging to both Z. pulchripenne and Z. paeneplanum ; the records that could not be verified are reported with a question mark in the paragraph “Distribution”, but excluded from the distribution map ( Fig. 13 ).
