Liriomyza projecta spec. nov.

Figs 184–188

Wing length 1.3mm (♂). Female unknown. Length of ultimate section of vein CuA 1 divided by penultimate section: 2.7. Eye height divided by gena height: 3.0. Scutum subshining. Orbital plate and parafacial very flat (somewhat translucent) and projecting, particularly anterodorsally.

Chaetotaxy: Three ori, one ors. Acrostichal setulae in approximately two sparse rows.

Colouration: Calypter margin and hairs grey. First flagellomere infuscated (not brown) with basal margin yellow; back of head, clypeus and ocellar triangle dark brown; posterolateral corner of frons to base of outer vertical bristle and small spot in front of inner vertical bristle dark brown, and space between verticals light brown; venter of gena with light stripe; face yellow, possibly brownish medially. Scutum with complete lateral yellow stripe with limited mottling next to scutellum; katatergite yellow with posteroventral corner brown; anatergite dark brown ventral to scutellum, and brown lateral to scutellum with dorsum yellow. Dorsal ¼ of anepisternum yellow (excluding dark posterior corner), with deep yellow dorsomedial emargination; anepimeron brown with yellow mottling; meron yellow dorsally; dorsum of katepisternum yellow to level of bristle and with small posterodorsal spot. Legs yellow with basal 2/3 of fore coxa brown, mid and hind coxae brown with tip yellow, femora brown at base, fore and mid femora with light streaking, hind femur with darker streaking, and tibiae and tarsi brown. Abdomen brown.

Genitalia: Figs 184–188 . Epandrium with long posteroventral process with small spine on inner-distal margin. Surstylus slightly darker than epandrium, tapering apically, with two long apical setae and one relatively long subapical spine; inner basal margin flanked by small dark plate with apical setae. Paraphallus absent. Hypophallus with broad base and long apical hairs. Distiphallus dark, strongly tapered to base; distal half much wider with apex slightly tapered, with ventral suture divided by thin plate, paired inner structures and with transverse anterodorsal sclerotization. Ejaculatory apodeme with duct broad and sclerotized at base; pileus ejaculatorius narrow with ends projecting and thickly sclerotized; blade very broad with distal margin dark and corners pale and slightly downturned.

Etymology. The specific epithet refers to the projecting parafacial and orbital plate, as well as the produced posterodistal margin of the epandrium.

Host. Unknown.

Range. USA. California [Modoc].

Type material. Holotype, USA. California: Modoc Co., 3mi NW Alturas, 8.vi.1970, J. Powell (1♂, EMEC).

Comments. Liriomyza projecta is a minute species similar in colouration to L. langei and L. trifoliearum . The male genitalia are distinct, however, and clearly distinguish it from Nearctic congeners: the posterodistal margin of the epandrium is strongly produced; the ejaculatory apodeme and the base of the ejaculatory duct are large and heavily sclerotized; there is an additional dark internal sclerite near the base of the surstylus; the paraphallus is absent; the hypophallus is broad basally; and the distiphallus is unique.
