Chalarus longicaudis Jervis, 1992

Chalarus longicaudis Jervis, 1992: 331 .

Diagnosis: Male genitalia ( Fig. 15 ) with phs straight and broad; tdp short, broad and rather pointed at apex, Lmtdp:Ltdp~2.75; both php broadened and covered with short hairs in the basal half, with strong marginal rim, almost twice the length of mtdp; all ejaculatory ducts placed distally on mtdp; ejaculatory apodeme nailshaped (as in Fig. 22 ). Female with frontal facets moderately enlarged (J92 Fig. 4 D); frons at narrowest point 2.5 times diameter of largest frontal facet; flagellum dark brown; legs dark brown, but base of femora may be paler; pulvilli of all legs of same size, shorter than distitarsus; hairs on femora, 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. 72 . See Table 1 for coxI and ITS2 barcode sequence accession numbers.

Annotations: Males of C. longicaudis were identified for the first time. Their genitalia greatly resemble C. brevicaudis but the tip of the distiphallus is short and broad and the phallic processes are broadened in the basal half only, with a strongly sclerotized rim and distinct hairs (compare Figs 14–15 ). Females possess a long and thin tergite 9 (piercer). The species has been reared from Empoasca vitis ( Jervis 1992) .
