Liriomyza fricki Spencer 1965: 35 View in CoL . Spencer 1969: 175; Spencer & Steyskal 1986: 136.

Description. Wing length 1.3–2.0mm (♂), 1.4–1.6mm (♀). Length of ultimate section of vein CuA 1 divided by penultimate section: 1.7–3.5. Eye height divided by gena height: 3.0–4.2. Scutum lightly dusted with pruinosity.

Chaetotaxy: Two ori (anterior bristle small to absent), two ors. Acrostichal setulae in two rows (sometimes three anteriorly).

Colouration: Calypter margin and hairs brownish. Head yellow with posterolateral margin of frons lateral to vertical bristles yellow to brown, back of head brown dorsally, and ocellar tubercle and clypeus brown. Scutum with complete lateral yellow stripe broadly overlapping scutellum; katatergite yellow; anatergite brown ventral to scutellum and sometimes ventrally brownish lateral to scutellum. Pleuron yellow with large spot on katepisternum and meron, and with small (sometimes very faint to indistinct) anteroventral spot on anepisternum and anepimeron. Legs yellow with fore tibia and tarsus brownish, mid and hind tarsus brown, and mid and hind tibiae brown at base, tip and on dorsal surface; material from western United States with tibiae yellow with dorsum thinly brown (paler or entirely yellow on anterior legs) and tarsi only brownish on distal three segments, becoming darker apically. Abdomen yellow with dorsum and epandrium brown.

Genitalia: Figs 104–107 View FIGURES 104–111 . Inner surface of epandrium flanked by one pair of dark, thin sclerites with terminal spine. Surstylus with single subapical spine and smaller accessory process. Hypophallus well developed. Swollen portion of ejaculatory duct strongly tapering to apex. Mesophallus thin, dark and fused to distiphallus. Distiphallus with large, bilobed and dorsally-swollen basal bowl with minutely-tuberculate inner surface, and with one pair of wide and very short apical tubules; membrane ventral to distiphallus thick and with skin-like texture. Ejaculatory apodeme with stalk thin and blade broad and dark with heavily sclerotized margin.

Hosts. Fabaceae Caragana pubescens (uncertain record), Lathyrus , Medicago , Melilotus , Trifolium sp. , T. hybridum , T. repens , Vicia , Vigna ( Spencer, 1969; Sehgal, 1971).

Range. USA: California [Glenn*, Nevada], Washington. Canada: Alberta, Ontario, Quebec .

Type material. Holotype, USA. Washington: Benton Co., Prosser (1♂, location unknown) ; Paratypes examined, USA. Washington: Yakima Co., Buena , ex. larva Trifolium hybridum , lot No., 207-1, K.E. Frick, 19.vii.1950 (1♂, USNM) , 10.vi.1950 (2♂, CASC) , Benton Co., Prosser, ex. larva Vicia rosa , 18.vii.1950, Lot. No. 227-1, K.E. Frick (1♂, USNM) .

Additional material examined. USA. California: Glenn Co., Maxwell , 1.viii.1953, R . F. Smith, Ladino clover (2♂ 3♀, EMEC) .

Comments. Liriomyza fricki is a pale, widespread species similar in appearance to L. trifolii , but the gena is smaller and posterolateral region of the frons is sometimes entirely yellow, not brown lateral to vertical bristles. The male genitalia are also distinct in that the distiphallus is large, minutely tuberculate and globose (reminiscent of L. lupini ), the membrane ventral to the distiphallus is textured and the ejaculatory apodeme is large and dark.
