Chalarus brevicaudis Jervis, 1992: 313 View in CoL .

Diagnosis: Male genitalia ( Fig. 14 View FIGURES 12 – 23 ) 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 View FIGURES 12 – 23 ). Female with frontal facets slightly enlarged (J92 Fig. 4 View FIGURES 1 – 6 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 View FIGURES 63 – 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 View FIGURES 12 – 23 ). 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).
