Description

(Figs 111 View Figures 107–115 , 112 View Figures 107–115 ). Wing length 1.2-1.7 mm (♂), 1.5-1.9 mm (♀). Length of ultimate section of vein M4 divided by penultimate section: 1.7-3.1. Eye height divided by gena height: 2.1-3.0. Scutum with light greyish pruinosity, rarely subshiny. First flagellomere rounded or with slight anterodorsal angle.

Chaetotaxy: Two ori; two ors. Acrostichal setulae in two to four scattered rows.

Colouration: Head yellow with back of head above foramen, ocellar tubercle, clypeus, and posterolateral margin of frons (not reaching base of outer vertical seta) brown. Scutum with complete lateral yellow stripe. Scutellum yellow with lateral corner brown. Metanotum brown with sclerites lateral to scutellum paler, sometimes with katatergite entirely yellow. Pleuron yellow with large ventral spots on katepisternum (not including seta base) and meron, and anepisternum and anepimeron with small anteroventral spots. Calypter margin and hairs brownish. Legs yellow with base of fore coxa sometimes brown, fore femur sometimes with dorsal mottling, base of mid and hind femora sometimes partially brown dorsally, and tibiae and tarsi brown (paler on fore legs). Abdomen brown with lateral margin broadly yellow and posterior margin of tergites (1)2-4 yellow; tergites 2-4 sometimes with yellow posteromedial emargination (sometimes forming complete line on tergite 4) and tergite 6 with anteromedial spot; epandrium brown, often with dorsum light brown to yellow; tergite 2 sometimes yellow along midline in females; if male abdomen entirely brown (some South American material), only two rows of acrostichal setulae present and most of anepisternum brown.

Genitalia: (Figs 636-639 View Figures 636–644 ) Epandrium with one posterodistal spine. Surstylus subtriangular, apex slightly truncated and with small inner-distal spine. Basiphallus sclerotised along left lateral margin and partially along dorsal margin; largely recessed distally where swollen section of ejaculatory duct dominates. Paraphallus narrow, weakly sclerotised. Hypophallus small, narrow. Mesophallus narrow, pale, slightly longer than wide and weakly fused to distiphallus. Distiphallus small, cup-shaped with subapical constriction; apex with characteristic minute triangular-shaped sclerotisations. Ejaculatory apodeme small with base curved and apex relatively narrow and clear; sperm pump with transverse sclerotisation.

Distribution.

Widespread throughout the Americas, Europe, and Asia.

Known hosts.

Host genera are listed in Lonsdale (2011); Abronia ( Nyctaginaceae ) and Mecardonia ( Plantaginaceae ) were added by Eiseman and Lonsdale (2018) and Eiseman et al. (2021), respectively.
