description: Spiriverpa bella (Kröber)
bella Kröber (1914:64 orig. desc.), Cole (1923:101 redesc., 1965:353 cat.) (Thereva); Irwin and Lyneborg (1981a:216 listing, comb. change) (Spiriverpa). Type locality Riverside, Massachusetts, USA. Holotype male in MCZ.
bella nigrimana Kröber (1914:64 orig. desc.) (Thereva); Irwin and Lyneborg (1981a:216 listing, comb. change) (Spiriverpa). Type locality Springfield, Massachusetts, USA. Holotype male in MCZ. New Synonymy.
nigrimana (Kröber), Cole (1965:353 cat.) (Thereva).
The holotype male of Thereva bella Kröber was compared with the holotype male of Thereva bella nigrimana Kröber and determined to be conspecific based on the shared characters of the epandrium in lateral view being bluntly pointed, the halteres and femora being yellow, and the distiphallus in lateral view being curved ventrally. Kröber erected this subspecies based on the abdomen being more silver than gold and the forefemora being reddish brown rather than yellow. Both of these characters are variable in S. bella.
Diagnosis. Like S. cinerascens and S. senex Walker, 1848 in having the male ommatidia of uniform size; halter knob pale yellow; inner gonocoxal setae yellow; ventral apodeme extending beyond anterior margin of dorsal apodeme (Fig. 23); female common duct longer than furca (as in Fig. 33); spermathecal ducts originating from posterolateral margins of spermathecal sac (as in Fig. 33). Like S. senex in having the setae on the male and female frons and parafacial white; and the gonostylus lacking basodorsal spines. It differs from S. senex in having the femora dark yellow; the ventral lobe (Fig. 20) with fine ventral setae; the setae on female mesonotum pale gold; and lacking setae on the median lobe of female tergite 9.

Biology. Spiriverpa bella has been handnetted and collected in Malaise traps in an old field, a second growth forest, a red maple swamp, and by baiting the Malaise trap with carbon dioxide (dry ice). Adults were collected between 4 June and 6 November.
Distribution. Spiriverpa bella has been collected from northwestern Georgia to New Hampshire west to Iowa and western Ontario (Fig. 35).
