Blaste falcifer
Smithers, 1979: 66
.
This species was described from a single male collected from southwestern
Tasmania
. Additional material of both sexes was obtained in this study and a description of the female is provided.
Material examined.
Specimen
on which description based:
Tasmania
, 1,
Cradle Mountain – Lake St Clair National Park
,
Athrotaxis selaginoides
, Weindorfers Forest

7 Feb 1987
. Additional records: many individuals collected from January to May
.
Description of female. Coloration
(after ca 5 years in alcohol). Identical to that of male, including fore wing (fig. 200) pattern.
Morphology
.
IO
:D = 2.3 (
IO
:D = 1.8 for male). Head larger than male. Antennae long, very slender, with sparse fine setae; sensory placoids: 3 base f 1, 1 apices f 4, f 6 and 1 central f 10; terminal segment bluntly rounded. Fore wing (fig. 200) with setae on posterior and anterior margins of veins

and
m
fused for a short length; both sections of vein
cu

Paraproct (fig. 202) with round field of 35 trichobothria. Subgenital plate (fig. 203) with apically setose rectangular median lobe. Gonapophyses (fig. 204): ventral valve with slender apical spiculate spine; dorsal valve with broad blunt spiculate apex; external valve transverse with large dorsal lobe. Spermathecal plate (fig. 205).

Remarks
. This locally widespread species was taken from some sites of rainforest, wet scrub and heath. In general morphology and fore wing pigmentation this species is nearly identical to that of
B. panops
. However, both sexes of the two species can easily be separated on genitalic characters: the hypandrium of males of
B. falcifer
has a pair of well developed, curved posterolateral processes which are lacking in
B. panops
; the strong median lobe of the female subgenital plate of
B. falcifer
contrasts with the very short and medially emarginate lobe of
B. panops
. The female genitalia of
B. falcifer
resemble those of
B. bistriata
(above) and
B. tillyardi
(below), but all can be separated on details of fore wing pigmentation. Specimens have been found to vary considerably in size. Fore wing lengths varied from 4.4–5.4 mm (), 4.0–4.7 mm ().
