DESCRIPTION: Male : Small size, total length 2.84–3.11, pronotal width 0.83–0.89 mm . COL- ORATION: Dorsum dusty pale green, with some darker bright green pigmentation on hemelytral margins, cuneus faded to yellow; forewing membrane translucent gray-brown, slightly darker patches laterally, veins yellow (perhaps faded from green) with color extending onto membrane around vein, major cell without colored spot (fig. 13). VESTITURE: Dorsum with moderately dense distribution of pale simple setae, intermixed with sparse distribution of more elongate darker, midmedium-brown, bristlelike setae.

GENITA- LIA: Pygophore: Dorsal margin of genital opening straight, one left lateral tergal process, only weakly produced from margin; left tergal process sclerotized and serrate, comblike (fig. 33A); ventral margin weakly convex medially; phalloguide with small, slightly sclerotized lobe, at base of right paramere articulation (fig. 33A). Left paramere: Apophysis tapering apically, apex narrow with strongly recurved hook (fig. 33B). Right paramere: Base short; paramere round in lateral view; apex strongly curved inward, apical margin bulbous; inner ventral margin with small sclerotized ridge, with minute serrations on margin; apical dorsal margin expanded into bulbous lobe, with small spine- like serrations; inner surface excavated (fig. 33C). Phallotheca: Opening large, distal to medial; strongly curved to right side; apical margin round; apex flattened; large subapical right ventrolateral tumescence; small left lateral tumescence; small right lateral basal tumescence; large medial lobe on right dorsal margin (fig. 33D). Aedeagus: Spicule arrangement: PES left ventrolateral to secondary gonopore, base wrapped sheathlike around part of secondary gonopore, DES2 left dorsolateral to PES, DES1 left lateral to DES2 (fig. 33); bases of PES and DES2 spicules flattened and broad, base of DES1 tubular and narrower; bases of all spicules originating adjacently at base of secondary gonopore (fig. 33F); PES bifurcate in distal third, branches subequal in length and both distally serrate, small, hooklike submedial process below bifurcation point, left branch weakly downcurved (fig. 33F); DES2 bifurcate in distal half, left branch bifurcate at apex with smooth distal margins, right branch twisted just above bifurcation point with serrate distal margins, right branch slightly shorter than left branch, left branch slightly longer than PES; DES1 unbranched, distally serrate, significantly shorter than other two spicules, basal keel elongate (DESk) (fig. 33E, F).

Aedeagus, dorsal. Scale bars = 0.1 mm. Female : Small, subovate, body length 2.81– 3.22 mm , pronotal width 0.82–0.89 mm . GENI- TALIA: Interramal lobes (fig. 48): mIRL partially joined to laIRL at base; laIRL uniformly narrow, curved inward at apex, base with small spiniferous lobe; mIRL moderately elongate, three-quarters height of laIRL, subrectangular with an acuminate apex, margin serrate.

DISTRIBUTION: Known from two localities in central Australia , Kings Canyon and Finke Gorge (map 2). This is the only Callitricola species from the Northern Territory . REMARKS: Callitricola finke is the smallest species in the genus and of all other callitroidinhabiting orthotylines. It is recognized by its pale dusty coloration, large, bulbous eyes (fig. 13), the phallotheca has a flattened and rounded apex as well as a prominent subapical right ventrolateral tumescence (fig. 33D), the shapes of PES and DES2 (fig. 33E, F), and the female interramal lobes with a more slender laIRL, and more slender and apically acuminate mIRL (fig. 48). This is a very distinctive species within Callitricola and C. gammonensis and C. wiradjuri are FIG. 33. Male genitalia of Callitricola finke . A. Pygophore, dorsal. B. Left paramere, ventral. C. Right paramere, right lateral. D. Phallotheca, dorsal. E. Aedeagus, right lateral. F. Aedeagus, dorsal. Scale bars = 0.1 mm. also a slighter paler and more dusty yellow-green (cf. to bright yellow-green). Callitricola finke is distinguished from both these species by its single serrate comblike left tergal process and the body is smaller than C. wiradjuri (fig. 13).
