Wing length 1.5mm in holotype, 1.8–2.1mm in non-types (♂), 1.9–2.2mm (♀). Length of ultimate section of vein CuA 1 divided by penultimate section: 1.6 (holotype), 2.2–2.4. Eye height divided by gena height: 3.8–4.2. Scutum subshining with light dusting of pruinosity.

Chaetotaxy: Two ori (sometimes only one on one side), two ors. Acrostichal setulae in four rows.

Colouration: Calypter margin and hairs grey. First flagellomere with distal 1/3–1/2 dark yellow to brownish, palpus brownish, and clypeus, ocellar tubercle and back of head dark brown; posterolateral corner of frons dark brown to base of inner vertical bristle, sometimes paler between base of vertical bristles. Scutum with complete lateral yellow stripe; katatergite yellow; anatergite yellow dorsally lateral to scutellum. Anepisternum yellow with thin posteromedial vertical stripe and broad transverse stripe that becomes narrower posteriorly; anepimeron with brown streaking; dorsal ¼ of meron and katepisternum yellow, with katepisternal bristle surrounded by yellow. Legs yellow with fore coxa brown at base, mid coxa mottled brown or only brown basally and hind coxa brown on dorsal half; femora brown basally, and tibiae and tarsi dark brown; fore femur sometimes with dorsolateral mottling on distal 1/3. Abdomen dark brown with lateral margin of tergites thinly yellow and posterior margin thinly to broadly yellow; tergite two sometimes with central yellow line.

Genitalia: Figs 138–141 . Surstylus with two subapical spines. Paraphallus absent. Hypophallus well developed. Mesophallus longer than wide, cylindrical and continuous with medial sclerotized process of distiphallus. Distiphallus directed dorsally; with clear, short and very broad donut-shaped basal section with small inner-distal spines and darker, cylindrical medial process. Ejaculatory apodeme with pileus ejaculatorius pale and reduced; blade pale apically and narrowing basally, blending with stem.

Hosts. Fabaceae — Lupinus albicaulis , L. latifolius , L. pratensis and probably other Lupinus spp.

Comments. Darker specimens with an entirely brown palpus (one female with palpus yellowish to base), which were likely influencial in the construction of Spencer’s (1981) original description, have been examined (with one male dissection) and found to be Liriomyza bellissima . These CNC specimens from British Columbia, labelled by Spencer as paratypes, were not listed in the original species description .
