DIAGNOSIS: Defined by the following characters: moderately large size; bright yellow-green coloration; forewing membrane veins yelloworange with color confined to veins only; left paramere with strongly recurved hook and subrectangular, apically truncate apophysis; right paramere with expanded subapical dorsal lobe with spinelike serrations on surface; right paramere apex enlarged and strongly curved inward to form large flange; phallotheca with twisted point at apex, left and right lateral tumescence, and subquadrate lobe on right dorsal margin near base of margin; female laIRL wider and weakly curved inward distally, base spiniferous with one small lobe; mIRL moderately elongate, three-quarters length of laIRL, subtriangular, margins and distal surface (sparsely) serrate.

DESCRIPTION: Male: Moderately large size, body length 4.73 mm, pronotal width 1.18 mm.

COLORATION: Dorsum yellow-green, mostly faded to yellow; forewing membrane light brown with slightly darker patches laterally, vein yelloworange, color confined to vein, major cell with faint green spot (fig. 13). VESTITURE: Dorsum with moderately dense distribution of pale to medium-brown simple setae. STRUCTURE: Head: Eyes very large, bulbous, greatly exerted from outline of head (fig. 13); antennae with AI subequal to vertex width, AII 1.5× pronotal width; labium elongate, extending just past metacoxae, over abdomen. Hemelytra: Cuneus and major cell of membrane elongate, major membrane vein straight (fig. 13). GENITALIA: Pygophore: Not examined, damaged. Left paramere: Apophysis subrectangular; apex truncate with strongly recurved hook; hook weak, reduced (fig. 47B, C). Right paramere: Base short; subtriangular in lateral view; apex enlarged and strongly curved inward, forming slightly sclerotized ridge along inner subapical ventral margin of paramere; subapical dorsal margin expanded into bulbous lobe, with small spinelike serrations covering surface (fig. 47D, E). Phallotheca: Dorsal opening large, narrows distally; apex with twisted point; large subapical ventral tumescence; left lateral tumescence present; large right lateral tumescence; small right lateral basal tumescence; small subquadrate lobe on right dorsal margin, subbasal (fig. 47A). Aedeagus: Not examined, teneral.

Female: Midsized, body length 3.97–4.46 mm, pronotal width 1.06–1.10 mm. GENITALIA: Interramal lobes (fig. 48): mIRL and laIRL partially joined at base; laIRL wider and weakly curved inward distally, base spiniferous with one small lobe; mIRL moderately elongate, threequarters length of laIRL, subtriangular, margins and distal surface (sparsely) serrate.

ETYMOLOGY: Named after the type locality, Wollemi National Park, northwest of Sydney. Noun in apposition.

HOST PLANT: From Callitris rhomboidea (table 2).

PARATYPES: AUSTRALIA: New South Wales: Wollemi National Park, Glowworm Tunnel Rd, 21 km N of Bungleboori Picnic Area, 33.26031 ° S 150.2181 ° E, 942 m, 05 Feb 2005, C. Symonds, Callitris rhomboidea , det. RBG Sydney, 2♀ ( AMNH _PBI 00005715, 00005716) ( AM).

DISTRIBUTION: Callitricola wollemi is known only from the type locality, on sandstone plateaus in the Wollemi National Park, near Newnes on the Great Dividing Range (map 3). Callitris rhomboidea and C. endlicheri grow together in this location, and where Callitricola wollemi and Erysivena sydneyensis also cooccur (table 2).

REMARKS: Callitricola wollemi is known only from one male and two female specimens. As the male specimen is teneral and the pygophore was damaged, it was not possible to describe the pygophore and aedeagus. However, from the structure of the right paramere and female genitalia, we were able to determine that this is a distinct species.

It is similar to Callitricola cordylina , C. graciliphila , and C. finlayae in external appearance; all are large in size, and have orange/yellow hemelytral membrane veins. The male phallotheca is very similar to that of C. cordylina with left and right apical tumescences (cf. figs. 47A and 32D, E). In addition, the subbasal lobe or the right dorsal margin of the phallotheca is subquadrate in both species (cf. figs. 32E and 47A). The left paramere of C. cordylina also has a subrectangular and truncate apophysis, with a strongly recurved apical hook (cf. figs. 47B, C and 32B). The right paramere of Callitricola wollemi differs from C. cordylina by having an enlarged apex and an enlarged and bulbous subapical dorsal lobe with spinelike serrations (fig. 47D). This bulbous subapical dorsal lobe is also found in C. parawirra (fig. 37D) and C. finlayae (fig. 35D), but C. wollemi is distinctive, with the lobe slightly smaller, and with a much larger and greatly expanded apical flange (fig. 47D, E), in comparison with C. parawirra and C. finlayae . The female interramal lobes of Callitricola wollemi are most similar to C. cordylina (cf. fig. 48), with an elongate subtriangular mIRL. However, in C. wollemi the mIRL is slightly less angular and basal lobe and spiniferous base of the laIRL are more expansive. See also remarks for C. cordylina .
