Figs 69–71 View FIGURES 69–75

Liriomyza californiensis Spencer 1981: 225 View in CoL . Spencer & Steyskal 1986: 120.

Wing length 1.3mm (♂). Female unknown. Length of ultimate section of vein CuA 1 divided by penultimate section: 2.3. Eye height divided by gena height: 4.8. Scutum shining.

Chaetotaxy: Two ori, two ors. Acrostichal setulae in four rows.

Colouration: Calypter margin and hairs grey. Head mostly light yellow with ocellar tubercle, back of head and clypeus dark brown; posterolateral margin of frons to base of outer vertical bristle dark brown, sometimes lighter to base of inner vertical; lateral margin of frons with thin stripe reaching level of anterior ors, sometimes with pigment extending to base of ors; first flagellomere, excluding basal margin, lightly infuscated; ventral margin of gena with brownish stripe. Scutum dark with lateral stripe yellow in front of transverse suture and brown to light brown behind; laterotergites dark with katatergite yellowish medially. Pleuron dark brown with dorsal margin of anepisternum and meron, and dorsomedial margin of katepisternum yellow; dorsal 1/3 of anepisternum, anepimeron, katepisternum and meron yellow in holotype. Legs brown with distoventral surface of femora yellow; mid and hind femora with additional yellow mottling in holotype, and fore femur yellow with base and distal half, excluding apex, brown. Abdomen dark brown.

Genitalia: Figs 69–71 View FIGURES 69–75 . Surstylus lobate with single short subapical spine. Basiphallus extensively sclerotized dorsally with apical membrane truncated and lightly pigmented. Paraphallus subrectangular, wider apically. Hypophallus well developed with darker base and short apical hairs. Mesophallus fused to distiphallus. Length of distiphallus slightly more than three times width at base, strongly narrowed and darkened basally, with complete ventral suture and clear apical chamber (inner surface minutely spinulose in holotype) surrounding paired fringed structures. Ejaculatory apodeme with pileus ejaculatorius darker along lateral margins; blade abruptly broader and paler apically, and with dark marginal band.

Hosts. Unknown; adult collected on Artemisia douglasiana (Asteraceae) .

Range. USA. California [Alpine*, Los Angeles, Riverside, San Francisco*].

Type material. Holotype, USA. California: Los Angeles Co., Corral Canyon Rd. , near main coastal highway, 27.iii.1977, on Artemisia douglasiana, K.A. Spencer (1♂, USNM).

Additional material examined. USA. California: Alpine Co., Hope Valley , 8.viii.1948, sweeping, Lot No. 91–30, K.E. Frick (1♂, CASC) , San Francisco Co., San Francisco , 4.iii.1964, P.H. Arnaud, Jr. (1♂, CASC) .

Comments. Similar to the more abundant Liriomyza artemisiae , L. californiensis is relatively dark species with an infuscated orbit (not yellow, as stated in the original description) and first flagellomere, with the base of the flagellomere yellow. The phallus is more similar to that of L. helianthi , however, in that the paraphallus is broad distally, and the distiphallus is narrow basally and expanded apically. The phallus is also nearly identical to that of L. freidbergi Spencer , although this species has an entirely black antenna and is known only from Israel ( Spencer 1974).
