:
Male.
Head
(
Figs 16, 17
). Gena pale golden pollinose, but parafacials, parafrontals, and postorbitals silver pollinose. Carina much narrower throughout than epistome, strongly convex in lateral view, protruding by about twice the width of a parafacial, forming a notch above epistome, ground colour golden, slightly pollinose. Facialridges setulose for only ashort distance above vibrissae. Vibrissae set a little above level of epistome margin, about as long as arista, incurved. Frons relatively narrow (
Table 3
), narrowest in front of ocelli; no fronto-orbitals, but dorsal 2- 3 interfrontals rec1inate. Gular swelling prominent.
Thorax.
Propleuron bare, apparently weakly sc1erotised. Hairs on anterior lappet of posterior spiracle
3-6 in
number, very inconspicuous. Setulae beneath posterior margin of scutellum sparse, but extending medially well past bases of second marginal bristles (as usual in
Ameniinae
). Lower calypter dark on protruding portion, posterior margin rounded.
Legs.
Fore tibia with 0 or 1
p,
1
pv
seta. Mid tibia with usual 1 strong submedian
a
seta, occasionally (lout of
6 specimens
) with2. Postero-dorsal strip ofhind coxa
bare.Abdomen.
Tl+2 dark.
T3
metallic green with (viewed from behind) median dark vitta and apical dark band, laterally with conspicuous silvery frosting.
T4
metallic green, in some lights broadly cupreous medially and darkened apically, sometimes with a trace of pale frosting laterally.
T5
more or less similar to
T4
.
Genitalia
as in
Fig. 13
; surstyle relatively broad and almost as long as cerci
.
Female. Resembling the male in most attributes, but frons narrowest across ocelli, with 2 strong fronto-orbitals.
Distribution (
Fig. 26
, p. 108). Known only from the vicinity of Alice Springs,
Northern Territory
, in very arid habitats.
