series only.
Female unknown.
Diagnosis.
Unique maculation: dark coppery iridescent ground colour with
four white blotches,
two on costa, two toward dorsum (
Fig 1
F). Male sclerite 9 forming a complete ring (
Figs. 12
A & B); valvae tapered with a minute mucron on inner apex (
Fig. 12
B); tergum 10 tapering to blunt apex (
Fig. 12
A).
Description.
Head interocular index of male 0.8. Male antenna with 52 (51–52) flagellomeres, scape and pedicel vestiture largely of lamellar scales, bronzy brown, a few longer creamy-yellow piliform scales overlaying the lamellar scales. First 3 flagellomeres filiform with vestiture of black lamellar scales, remainder of extreme moniliform, black; each ascoid with 7 curved branches (at mid-length of antenna). Mandibles functional, maxillary palps moderate length, 1.3x head width at compound eyes.
Head capsule brown with dense tufts of creamy-white piliform scales. Lamellar scales of palps silvery white.
Tegulae with shining bronzy-brown lamellar scales. Dorsum of thorax with shining bronzy-black lamellar scales; scales of coxae, femora and tibiae largely shining white, but fore-tibia and hind-tibia with bronzy-grey scales along anterior surface; fore-tarsus bronzy-grey, mid-tarsus grey with indistinct white bands, hind-tarsus dark bronzy-grey. Abdomen silvery-grey scaled.
Forewing length of male
3.7mm
(3.5–3.9). Maculation unique (
Fig. 1
F); ground colour rich brown with strong coppery-bronze iridescence. Basal costal streak absent but with four primary shining white fasciae and two secondary patches; a large oblique costal blotch at mid-length, separated from a smaller blotch on the termen in the same position; two similar blotches at three quarters on costa and termen, but with rows of black scales along the veins; a small, indistinct streak of paler scales about halfway along the cubital sulcis and a few pale scales in apex of wing. Fringes grey-brown with white tips but wholly white adjacent to the fasciae.
Hindwing with 3 frenular bristles; dark grey scaled with bronzy lustre.
Male abdomen and genitalia.
[G920] (
Figs 12
A–E) No trace of a transverse sclerite on dorsum of A1. Exit area of S5 gland developed into a typical sabatincoid protuberance bearing about 17 long piliform scales. S8 not evident as a discrete sclerite although possibly represented by a small flange at the anterodorsal corner of sclerite 9, extending beyond the thickened margin and bearing a few microsetae. Sclerite 9 relatively large, 1.5x length of S6 along ventral mid-line, developed as a complete ring, with a broad band across the dorsum, unique in this genus; anterior concave margin thickened. Valvae simple, tapering, 2.2x longer than wide, with a small incurved mucron at the apex; inner surface uniformly clothed with curved setae, those at apex strongly orientated as ‘retro-setae’. Tergum 10 simple, hood-like, tapering to a blunt apex, a little short of the valve length; a small area of short retro-setae present on either side of the apex, on the ventral aspect. Anal cone well developed with lateral sclerite bearing microtrichia. Phallus average for the
calliplaca
-group, 2.2x length of S6; gonopore terminal with a gaping ‘fish-mouthed’ aperture surrounded by radial folds, a reduced ventral bulb present; phallocrypt densely clothed with acutely pointed scales.

Remarks.
This, the largest of the
calliplaca
-group of species, is also the most straightforward to identify. Interestingly, it is the only
Tasmantrix
species in which the male exhibits a sabatincoid
type
of S5 gland protuberance. It occurs associated with
Nothofagus cunninghamii
forest remnants.
Etymology.
Species name derived from its geographic location in Tasmania.
