Notiothereva albiventris (Philippi)

( Figs. 1–8 , 44).

albiventris Philippi (1865:770 orig. desc.) ( Thereva ); Metz & Irwin (Metz et al. 2003:243 listing, comb. change, 244: trans. orig. desc., LT design.) ( Notiothereva ). Type locality Santiago, Chile. Lectotype male in MNNC.

ruficornis Kröber (1911: 498 male key, 520 orig. desc.; 1913:33 dist.; 1928:7 dist.), Stuardo­Ortiz (1946:87 cat.) ( Psilocephala ); ( Metz et al. 2003:244 comb. change, 245: trans. orig. desc.) ( Notiothereva ). Type locality Chile, Concepción. Holotype male in Hermann Collection, presumed lost ( Metz et al. 2003:244). New synonomy.

No distinct characteristics were provided in the description of Psilocephala ruficornis Kröber that would clearly separate this species from Notiothereva albventris (Philippi) . This species shares with N. albiventris the femora being dark brown to black with white setae; the tibiae and tarsi being yellowish brown with darkened tips; the wings pterostigma dark brown to black, distinct; and cell m 3 being closed. The type locality was given as Concepción, Chile, which falls within the distribution pattern of N. albiventris ( Fig. 44). Kröber named this species for the light reddish yellow first flagellomere of the antenna. Although this character is generally dark brown in N. albiventris , there is some variability with this character.

Diagnosis. Like Notiothereva aurea and N. simulata in having the frontal setae extending lateral to antennal base; parafacial with setae; and gena lacking anterodorsal patch of short, dark setae. It is similar to N. aurea in having dorsocentral macrosetae; halter dark brown; tibia dark yellow, apex dark reddish brown; setae on frons and parafacial predominately white; and cell m 3 closed. It differs from N. aurea in having mesonotal setae white and dark brown intermixed with appressed, short, gold setae; setae on scutellum white; cervical sclerite lacking setae; and the setae on male sternite 8 ( Fig. 3 ) continuous across posterior margin.

Distribution. Notiothereva albiventris is known from Argentina and Chile ( Fig. 44). Habitats and Temporal Phenology. Notiothereva albiventris has been hand­netted in a dry wash; collected in Malaise traps set on a hillside draw, in Nothofagus forest, in a damp wash, along a swift stream, on dry plains, and in a gully; and collected in pan and pitfall traps. Adults have been collected from October to April, but most abundantly in November and December.

Specimens Examined. Type specimen. The lectotype male of Thereva albiventris is labeled "Santiago, Chile " (MNNC). Other specimens. Numerous duplicate specimens of N. albiventris were collected by M.
