Chalarus pughi Coe, 1966

Chalarus pughi Coe, 1966: 154 .

Diagnosis: Male genitalia (as in Fig. 1 ) with phs gently curved; tdp short and pointed, Lmtdp:Ltdp~2.0; php absent; all ejaculatory ducts placed distally on mtdp; ejaculatory apodeme parasol-shaped (as in Fig. 18 ). Female with frontal facets greatly enlarged (J92 Fig. 1 E); frons at narrowest point less than 2.0 times diameter of largest frontal facet; flagellum mid to dark brown; femur dark brown with base and apex yellowish; tibia yellow but brown ventromedially, tarsi yellowish; pulvilli of front and mid legs twice the length of hind legs and longer than distitarsus; hairs on femora, thorax and abdomen yellow to light brown; hind femur with apical hairs of pdsr extending as far as apex; abdominal tergites either evenly dark brown or with tergites 1–3 being considerably paler (yellowish); ovipositor as in Figs 34, 36 & 38 . See Table 1 for coxI and ITS2 barcode sequence accession numbers.

Annotations: Chalarus pughi was described from females only (holotype and four paratypes studied) and its male counterpart is characterised here for the first time, being morphologically indistinguishable from male C. fimbriatus . Genetically, they can be identified by their ITS2 genotype ( Table 2 ). Recorded hosts are Edwarsiana geometrica , Edwarsiana spec., Eupteryx aurata and Eupteryx urticae .
