Nanniella chalybea Reuter, 1904 * tropical Africa Nanniella gracilis Linnavuori, 1975 Sudan; Cameroon Nanniella pallidiceps Linnavuori, 1973 Zaire Nanniella palustris Linnavuori, 1975 * Equatorial Africa Nanniella reuteri Poppius, 1914 south-east Africa Biology and host plant associations: No host information has been collected for this genus. Nanniella alkithoe has been collected at light in savannah forest; Nan. gracilis and Nan. chalybea have both been found in mountain meadows, with the latter also collected in clearings, rain and savannah forests; and Nan. palustris is known from swampy meadows and moist clearings in rain and savannah forests, and is common across western Africa (Linnavuori, 1994). Remarks: Our phylogenetic analysis confirms the sister taxon relationship of Nanniella and Acratheus. As discussed above, both share many similarities, notably the dense, elongate punctures covering the body, the structure of the MTG external efferent system, and the male and female genitalia. This redescription is based on examination of Nan. chalybea and Nan. palustris, as well as review of the literature (Linnavuori, 1994).
