Kaminski 2016 : 245. Material examined (data represents single specimens unless otherwise noted). Holotype (TMNH): "Marandella Mashld XI.97 GKMarshall; Holotype No: 1877 Phylacastus rhodesianus KOCH; Phylacastus rhodesianus Koch DET.C.KOCH; Phylacastus rhodesianus Koch." Additional material examined (MNHN). " 9.VI.1970 Vumba SUD RHODESIE Cl. Besnard leg. 8.VI.1970 Inyanga SUD RHODESIE Cl. Besnard leg." ( 10 specimens ) . Redescription. Length 6-8 mm. Head : punctures separated by ≤ 1 diameter. Mentum midportion broad, concealing lateral wings, midportion without distinct median carina. Prothorax : pronotum punctate, punctures closely spaced, separated by ~1 diameter. Hypomeron very lightly textured, without clear punctation. Prosternal process produced between forecoxae. Pterothorax : elytra width about equal to pronotal width. Elytral striae and intervals punctate; striae impressed. Interval punctures fine, closely spaced (~1 diameter), distinctly smaller than strial punctures. Elytral tubercles present on apical declivity. Abdomen : ventrite V sulcus narrowly separated from apical border. Terminalia : male: parameres converging apically, fused basally with deep and wide opening at apex exposing median lobe (Fig. 4C ). Female: ovipositor slightly elongate (ratio of ovipositor coxites I-IV to paraprocts <1:1). Bursa copulatrix bilobate, accessory gland present near-to spermatheca, accessory pouch absent. Distribution. Zimbabwe.
