Liriomyza tubula Spencer

Figs 229–231

Liriomyza tubula Spencer 1981: 282 . Spencer & Steyskal 1986: 133.

Wing length 2.0mm (♂), 2.3–2.4mm (♀). Length of ultimate section of vein CuA 1 divided by penultimate section: 2.2–2.3. Eye height divided by gena height: 2.8–4.8. Scutum lightly dusted with pruinosity. Parafacial and anterior section or orbital plate projecting, particularly along anterodorsal margin of eye. First flagellomere subquadrate and slightly longer than high.

Chaetotaxy: Two ori, two ors (sometimes one on one or both sides). Acrostichal setulae in two irregular rows.

Colouration: Calypter margin and hairs grey. First flagellomere orange with dorsobasal margin lightly infuscated; posterolateral corner of frons dark brown to base of outer vertical bristle; clypeus, back of head and ocellar triangle dark brown; face brownish medially in non-types. Scutum with complete lateral yellow stripe; katatergite yellow; anatergite brown, becoming darker below scutellum and yellow dorsally beside scutellum. Anepisternum yellow with thin oblique brown stripe and thin brown stripe along posteroventral margin; anepimeron with posterior margin and thin anterior mottling brown; ventral 2/3 of meron brown; katepisternum brown with dorsomedial and sometimes (non-types) anterodorsal margin yellow. Outer surface of fore and mid coxae brown on basal half; hind coxa brown; femora broadly brown at base, fore femur brown dorsally (excluding knee) and mid and hind femora with brown dorsal spot at 2/3 length (types with additional dorsal streaking); tibiae and tarsi light brown, with base of fore tibia yellow in non-types and pigment dark brown in holotype.

Genitalia: Figs 229–231 . Surstylus tapering apically and with one subapical spine. Paraphallus slightly wider apically. Hypophallus thin with long apical hairs. Mesophallus not much longer than wide, fused to base of distiphallus. Distiphallus long and bifid with wide basal, spinulose collar; tubules mostly narrow and clear with base slightly darker and bulging. Ejaculatory apodeme relatively dark with base of duct pigmented; pileus ejaculatorius with thick, dark lateral margins; blade very broad and lighter on distal half with distal margin dark.
