Liriomyza cf. trixivora Lonsdale 

( Figs. 20, 21View FIGURES 14–26, 50, 51View FIGURES 46–56)

Material examined. CALIFORNIA: San Diego Co., Bow Willow , 8.iii.2017, em. 23–29.iii.2017, C.S. Eiseman, ex Trixis californica  , puparium in blister on lower leaf surface, CSE3283,  CNC940103–940106View Materials (1³ 3♀)  ; same col- lection data, em. 25.iii.2017, pupation external, #CSE3295, CNC940102View Materials  (1³).

Host. Asteraceae  : Trixis californica Kellogg. 

Leaf mine. ( Figs. 50, 51View FIGURES 46–56) Upper surface; whitish, entirely linear, with the frass in conspicuous alternating black strips. A short terminal portion is formed on the lower surface, where the larva cuts a crescent-shaped exit slit in the epidermis before pupating.

Puparium. ( Figs. 21View FIGURES 14–26, 50View FIGURES 46–56) Dark brown; in some cases formed externally and in others within the mine or partly protruding from the exit slit.

Distribution. USA: CA; we have found similar leaf mines in AZ.

Comments. The mine and larval habits of this species have not been described previously, apart from the statement by Lonsdale (2011) that the last instar larva pupates inside the leaf. The specimens examined here ( Fig. 20View FIGURES 14–26) differ slightly from the type series, also from California, and are only tentatively identified: the ventromedial suture of the distiphallus is raised as a shallow carina and the paraphallus is apically hooked.
