Chalarus fimbriatus Coe, 1966

Chalarus fimbriatus Coe, 1966: 153 .

Chalarus kamijoi Morakote , in Morakote & Hirashima, 1990: 170. Synonymy: Jervis (1992: 269).

Diagnosis: Male genitalia ( 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 slightly enlarged (J92 Fig. 1 C); frons slightly narrowed, at narrowest point 2.5 times diameter of largest frontal facet; flagellum light to dark brown; femur dark brown with base and apex yellowish; tibia yellow but brown ventromedially, tarsi yellowish; pulvilli of all legs of same size, shorter or as long as distitarsus; hairs on femora light brown; hairs on thorax and abdomen light to mid brown; hind femur with apical hairs of pdsr extending as far as apex; abdominal tergites evenly dark brown or tergites 1–3 considerably paler (yellowish); ovipositor as in Fig. 40 . See Table 1 for coxI and ITS2 barcode sequence accession numbers.

Annotations: The type series was studied while on a visit to NHM. Females can reliably be identified but males are morphologically identical to C. pughi . Jervis’ Form C of C. fimbriatus — male with one to two pairs of fronto-orbital setae — probably represents a frequently occurring aberration. Jervis’ (1992) Forms A and B of female C. fimbriatus ( Figs 41–42 ) might represent the missing partner for C. absconditus , what needs to be tested by DNA sequencing or ecological observations (couples captured in copula or rearing). Both female forms are included in the identification key. Females of C. fimbriatus were reared from Alnetoidia alneti . Male rearing records from A. alneti , Eupteryx urticae and Edwarsiana sp. should be attributed to C. fimbriatus agg.
