Liriomyza abnormis Spencer 1981: 209 View in CoL . Spencer & Steyskal 1986: 131.

Description. Wing length 2.5mm (♂). Female unknown. Length of ultimate section of vein CuA 1 divided by penultimate section: 2.6. Eye height divided by gena height: 5.0. Scutum shining.

Chaetotaxy: Two ori on right side, one on left, two ors. Acrostichal setulae in four rows.

Colouration: Calypter margin and hairs brownish-grey. Head yellow with first flagellomere darker yellow, ocellar tubercle, back of head and clypeus dark brown; posterolateral corner of frons dark to base of outer vertical bristle, and slightly lighter to base of inner vertical bristle. Scutum with complete yellow lateral stripe; katatergite yellow with ventral margin brownish; anatergite dark below scutellum, and with lateral section paler with posterodorsal corner yellowish. Anepisternum with large irregular brown subventral stripe; anepimeron with brown mottling; meron brown with dorsal margin yellow; ventral ¾ of katepisternum brown (bristle surrounded by yellow with brownish mottling to rear). Legs yellow with base of fore and mid coxa brown, basal third of hind coxae brown, base of femora narrowly brown dorsally, and tibiae and tarsi brown. Abdomen colour unknown.

Genitalia: Figs 15–18 View FIGURES 15–18 . Surstylus absent. Epandrium without spines. Basiphallus strongly bent medially; left anterior margin produced as long, dark, pointed process. Paraphallus extremely thin. Hypophallus ill-defined, haired along length. Apical swelling of ejaculatory duct nearly spherical. Distiphallus with long, medially bent stem and large apical bowl; bowl large, globose, with inner marginal row of thick spines, and enclosing paired fringed structures. Ejaculatory apodeme with ends of pileus ejaculatorius dome-like and terminating in thick, dark process; base of duct dark; blade broad, darker than stem, and with pale marginal and subapical band.

Host. Unknown, probably Poaceae .

Range. USA. California [Alameda].

Type material. Holotype, USA. California: Alameda Co., Berkeley Hills , 1400’, NE of Oakland, 8.iv.1964, P. Rude, Type No. 14058 (1♂, CASC).

Comments. Liriomyza abnormis , still known only from the holotype, is a relatively large species with male terminalia similar to those of other grass-feeders such as L. septentrionalis (see comments of L. graminaceae for discussion), except that the paraphallus is present, the apical bowl of the distiphallus is extremely large, and the enclosed processes are large, pale and fringed (not smooth, short and dark).
