Delia platura (Meigen, 1826)

( Figs. 4–6 ; 14, 15)

Diagnosis: General coloration dark brown with silver pruinosity, thorax with dorsal, light brown stripes; palpus dark brown; prealar seta short, never as long as notopleural setae; dorsocentral setae 2+3; katepisternal setae 1+3; legs dark brown; lower and upper calypters of the same size; vein C bare on ventral surface ( Fig. 6 ); mid tibia with one submedian anterodorsal, two posterodorsal and two posteroventral. Male: hind femur with three posterodorsal setae; hind tibia with more than 18 posteroventral short erect setae. Body length: 5.2–6.0 mm. Wing length: 5.2–5.5 mm.

Material examined: CHILE: Juan Fernández , Robinson Crusoe Island, 1 male and 1 female, Bahia Cumberland, 1–11.i.1993, Marshall & Gonzalez leg.

References: Kim & Eckenrode (1984); Savage et al. (2016).

Distribution: cosmopolitan species found in all biogeographic regions, except Antarctica (Griffiths 1997).

Biology: The species is polyphagous, and is considered an important agricultural pest of innumerable plant species of commercial interest ( Savage et al. 2016).

Comments: Hennig (1955) identified 28 specimens of Delia platura sanctijacobi (Bigot, 1885) in Robinson Crusoe Island, two in Santa Clara Island and one in Alejandro Selkirk Island ( Table 1). Delia sanctijacobi (Bigot, 1885) is now considered a valid species ( Pape & Thompson 2013), also with economic importance in Argentina ( Hamity & Roman 1987).
