Chalarus brevicaudis Jervis, 1992

Chalarus brevicaudis Jervis, 1992: 313 .

Diagnosis: Male genitalia (Fig. 14) with straight and broad phs; tdp long and rounded, Lmtdp:Ltdp~1.75; both php broadened, rather hyaline, without strong marginal rim, almost twice length of mtdp; all ejaculatory ducts placed distally on mtdp; ejaculatory apodeme nail-shaped (as in Fig. 22). Female with frontal facets slightly enlarged (J92 Fig. 4 B); frons slightly narrowed, at narrowest point 3–3.5 times diameter of largest frontal facet; flagellum dark brown; legs dark brown but base of femora, area around femoral-tibial joints and tarsi may be somewhat 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 Figs 73 & 75. See Table 1 for coxI and ITS2 barcode sequence accession numbers.

Annotations: Inner male genitalia of C. brevicaudis are closest to C. longicaudis but differ in that they have a distinctly longer tip of distiphallus and differently shaped phallic processes, the latter being more translucent, i.e., hardly sclerotized, and broadened almost to their apex (compare Figs 14–15). The female ovipositor is unique in its dorsal and lateral aspect. Jervis (1992) mentions a female Form A near brevicaudis with only very slightly enlarged ommatidial facets at the front and a slightly expanded rather than constricted frons — not included in the identification key. The single known host species is Empoasca vitis, in which the first instar larva overwinters (Jervis 1992).
