Liriomyza temperata Spencer

Figs 626-631

Liriomyza temperata Spencer in Spencer and Steyskal 1986: 294. Lonsdale 2017: 94.

Description

[from Lonsdale (2017)]. Wing length 2.4 mm (♂), 2.1-2.7 mm (♀). Length of ultimate section of vein CuA1 divided by penultimate section: 2.1-2.9. Eye height divided by gena height: 3.8-6.9 [head missing in holotype]. Scutum subshiny.

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

Colouration: Calypter margin brown. Head yellow with ocellar triangle and back of head dark brown; lateral corner of frons dark brown, becoming paler to base of outer vertical seta; clypeus dark brown with centre sometimes paler. Scutum with complete yellow stripe laterally. Lateral corner of scutellum with small brown spot. Katatergite brown posteriorly; anatergite brown with dorsum yellow; mediotergite dark brown. Anepisternum with brown stripe across ventral 1/2; anepimeron yellow with brown streaking (paler posteriorly); meron brown with dorsum yellow; ventral 2/3 of katepisternum brown. Legs yellow with bases of coxae brown, tibiae, and tarsi brown (anterior legs paler); hind femur sometimes brown dorsobasally, and if so, fore and mid femora sometimes also similarly brown. Abdomen dark brown with lateral margin of tergites yellow.

Genitalia: (Figs 630 , 631 ) Surstylus broad with two long posterobasal spines (not apical to subapical). Phallophorus with long, narrow dorsal process that is sharply bent ventrally. Basiphallus with left lateral and dorsoapical surfaces sclerotised. Hypophallus short with long subapical hairs. Paraphallus pale and narrow with venter darker. Mesophallus short, thick-walled dorsally, narrowed basally and distally; mesophallus and distiphallus with complete ventral suture. Distiphallus cup-shaped, slightly compressed dorsoventrally towards darkened base; with few spines along distal margin of shallow medial and apical chambers. Ejaculatory apodeme with narrow stem and clear marginal band; sclerite of sperm pump highly reduced.

Variation: (Figs 626-629 ) Non-type males differ as follows: wing length 1.9-2.2 mm; eye height divided by gena height 6.7-8.0; two ori and ors; femora entirely yellow; stripe on anepisternum sometimes narrower; extension on the left distal margin of the basiphallus shorter and narrower; paraphallus slightly thicker; mesophallus ~ 1/3 shorter; distiphallus higher, stouter, with more conspicuously delimited short medial chamber and with base broader (apparently shorter with more rounded base in illustration in original publication, but this may be an artifact); ejaculatory apodeme more weakly sclerotised marginally on blade and not more heavily sclerotised on lateral margin of blade furthest from duct; sclerite of sperm pump weaker and not produced laterally.
