Liriomyza schlingeri Spencer

Figs 208, 209

Liriomyza schlingeri Spencer 1981: 269 . Spencer & Steyskal 1986: 130.

Wing length 1.4–1.5mm (♂), 1.7mm (♀). Length of ultimate section of vein CuA 1 divided by penultimate section: 2.1–2.6. Eye height divided by gena height: 4.2–5.5. Scutum subshining.

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

Colouration: Calypter margin and hairs grey. Posterolateral margin of head to base of outer vertical bristle, ocellar triangle and back of head brown; clypeus yellow, sometimes brown laterally. Scutum with complete lateral yellow band; katatergite yellow; anatergite dark brown below scutellum and paler laterally. Anepisternum with broad transverse stripe that is highly reduced in non-types; anepimeron sometimes with brown mottling; most of meron brown; katepisternum brown to level of bristle. Legs yellow with base of mid and hind coxae brown (broader on hind coxa), hind femur possibly narrowly brown at base, tibiae brown to light brown and tarsi light brown, becoming paler to base. Abdomen brown with lateral and complete central stripe on all tergites yellow, posterior margin of tergites thinly yellow (incomplete medially on tergite 1) and epandrium yellow dorsally.

Genitalia: Figs 208, 209 . External terminalia as described for L. sativae . Paraphallus thin and subrectangular. Hypophallus with distal section short-haired and nearly separate. Mesophallus approximately as long as wide, separate from distiphallus; mesophallus and distiphallus with complete ventral suture. Distiphallus darker, tapered at base and with basolateral and dorsal surfaces thick; distal half thin-walled with one pair of dark internal fringed structures.

Hosts. Asteraceae — Baccharis sp. , B. glutinosa *.

Range. USA. California [Los Angeles, Riverside].

Type material. Holotype, USA. California: Riverside Co., Deep Canyon , 30.v.1963, reared from Baccharis sp. , E.I. Schlinger (1♂, CASC) ; Paratype examined, USA. California: Los Angeles Co., Los Angeles , 3.iv.1915, M.C. VanDuzee (1♂ [head missing], CASC) .

Additional material examined. USA. California: Riverside Co., Riverside , 19.viii.1959, Baccharis glutinosa (3♂ 1♀ 1?, UCD) .

Comments. Liriomzya schlingeri is externally similar to other Liriomyza with entirely yellow femora, particularly L. sativae (also found on Baccharis ), but subtle characters of the phallus can be used to distinguish them. The examined paratype was not listed in the original description, but bears a circular paratype label typical of Spencer’s other species.
