Diagnosis: Male with dark brown hairs on femora, except pvsr of mid femora where they are whitish to light brown. Genitalia with inner gonopod and surstylus as in Figs 28 & 33 View FIGURES 24 – 33 . Phallus ( Fig. 10 View FIGURES 7 – 11 ) with phs straight; tdp short and broad; Lmtdp:Ltdp~3.0; two php which are slightly shorter than mtdp; all ejaculatory ducts placed distally on mtdp; ejaculatory apodeme parasol-shaped ( Fig. 19 View FIGURES 12 – 23 ); Female with frontal facets greatly enlarged (J92 Fig. 3 View FIGURES 1 – 6 B, as C. parmenteri ); frons very narrow, at narrowest point 1.0 times diameter of largest frontal facet; flagellum dark brown; legs dark brown, but base of femora and area around femoral-tibial joints may be somewhat paler; pulvilli of all legs of same size, shorter than distitarsus; hairs on femora dark brown, but pvsr of mid femur and apical hairs of aasr on hind femora whitish to light brown; hairs on thorax and abdomen dark brown; hind femur with apical hairs of pdsr extending as far as apex; abdominal tergites dark brown; ovipositor as in Fig. 58 View FIGURES 49 – 62 .

Annotations: Chalarus griseus was described from the male holotype (studied), characterised by a pale golden posteroventral hair fringe on the mid femora (instead of dark brown to black). This characteristic was present in four males belonging to two species: CK268 and CK344 belonging to C. griseus , plus CK57 and CK335 belonging to the newly described C. saxonicus . Although applied in the identification key provided, it is not absolutely certain whether the coloration of the femoral hair fringes of the male can be regarded as a constant identification feature. The female sex is associated with male C. griseus for the first time here, being formerly erroneously regarded as C. parmenteri sensu Jervis (1992) nec Coe, 1966 (see below under C. holosericeus ). Jervis (1992 & in litt.) reared female C. griseus (cited as C. parmenteri ) from Alebra albostriella , Fagocyba cruenta and an unidentified typhlocybid on Quercus robur , the host record of Typhlocyba quercus (only mentioned in his Table 1) was erroneously listed.
