COLORATION: Faded yellow-green dorsum, often faded to yellow; forewing membrane light brown, veins yellow-orange with tint confined to vein only, major cell with dark green spot medially that is sometimes faded in dried specimens (fig. 13). VESTITURE: Dorsum with moderately dense distribution of simple setae. STRUCTURE: Head:Antennae with AI 1.5× vertex width, AII 2× pronotal width; labium elongate, extending beyond metacoxae over abdomen. Hemelytra:Cuneus elongate; major cell of membrane greatly elongate, major membrane vein straight. GENITALIA: Pygophore:Dorsal margin of genital opening weakly concave, with one sclerotized left lateral tergal process, and broad tergal lobe, narrowing apically, positioned right of midline; left tergal process, short, digitiform, surface from base to apex with minute spinelike serrations, apex round; ventral margin very weakly convex medially; phalloguide broadly subrectangular, margin ventrad to right paramere articulation with weakly expanded round lobe, sclerotized and with minute spinulae (fig. 36A). Left paramere:Apophysis subrectangular, apex truncate with strongly recurved hook (fig. 36B). Right paramere:Base elongate; apex twisted, not curved inward; inner subapical ventral margin constricted to form small. well-defined ridge, slightly more sclerotized than rest of paramere, margin with minute spinulae; subapical inner dorsal margin slightly swollen, covered with minute spinulae; mesiolateral surface weakly excavate (fig. 36C, D). Phallotheca:Dorsal opening large, pointed distally; apex with twisted point; large subapical ventral tumescence; left lateral tumescence; large right lateral tumescence; small right lateral basal tumescence; large, round lobe on right dorsal margin, subbasal (figs. 36E–H). Aedeagus:Spic- ule arrangement (fig. 36): PES left ventrolateral to secondary gonopore, not wrapped sheathlike around secondary gonopore, DES2 dorsad to PES and secondary gonopore, DES1 dorsad to DES2; base of PES slightly more distal to bases of DES1 and DES2 (which are adjacent) (fig. 36I, J); PES, bifurcate in distal third, branches short, constricted slightly before bifurcation point, left branch short and strongly curved downward, right branch very short, further divided at apex, all branches distally serrate (fig. 36I); DES2 bifurcate in distal half, branches equal in length, both narrow and acuminate, distally serrate (fig. 36J); DES1 bifurcate in distal half, branches unequal in length, dorsal branch greatly reduced to round lobe with smooth margins, ventral branch elongate slightly constricted below leafshaped apex, distal margins serrate (fig. 36J); DES1 basal keel (DESk) elongate (fig. 36J).  Female: Large, slightly subovate, body length 4.55–5.22 mm, pronotal width 1.17–1.31 mm. GENITALIA: Interramal lobes (fig. 48): mIRL partially joined to laIRL at base; laIRL uniform width, straight, base spiniferous with two spiniferous lobes, one large and one small; mIRL elongate, almost as long as laIRL, subrectangular, margins and distal surface sparsely serrate.  ETYMOLOGY: The name of this species come from a combination of the host-plant species name  Callitris gracilisand Greek philameaning “lover.”  HOST PLANTS: Known from  Callitris gracilisin Victoriaand  Callitris verrucosain South Australia(table 2). Hosts from two other localities in South Australiawere unable to be identified to species; this is in a region where a number of  Callitrisspeciesare known to cooccur and hybridize ( Hill, 1998).    HOLOTYPE:  AUSTRALIA: South Australia:  7 kmE Para Wirra National Parknear Williamstown, 34.70001 °S 138.85 °E,  250 m,  31 Oct 1995, Schuh, Cassis, and Gross,  Callitrissp., Field ID, 1♂( AMNH_ PBI 00002453) ( SAMA).  PARATYPES:  AUSTRALIA: South Australia: 7 kmE Para Wirra National Park near Williamstown, 34.70001 °S 138.85 °E, 250 m, 31 Oct 1995, Schuh, Cassis, and Gross,  Callitrissp., Field ID, 1♂( AMNH_PBI 00002452), 5♀( AMNH_PBI 00002455–00002459) ( AMNH), 1♂( AMNH_PBI 00002454), 4♀( AMNH_PBI 00002460–00002463) ( SAMA). 11 kmW of Gawler, 34.60001 °S 138.6167 °E, 100 m, 31 Oct 1995, Schuh, Cassis, and Gross,  Callitris glaucophyllaor gracilis, det.

It was collected with other  Callitricolaand  Erysivenaspecies, including at four localities with  E. schwartzi(table 2).  REMARKS: The form of PES and the phallotheca relates  Callitricola graciliphilato C. cordy-  lina. It can be differentiated from  C. cordylinaby the following characters (cf. figs. 13, 32): larger size; presence of a left lateral tergal process on the pygophore; a larger right subbasal lobe on the phallotheca; PES having a shorter and downturned left branch; DES2 more distally bifurcate in the distal third, with the subbranches of equal length and narrow; DES1 having a short dorsal branch reduced to a round lobe with smooth margins; the female laIRL of uniform width and narrow with two basal lobes (as opposed to slightly broader and incurved distally, with only one basal lobe); and the mIRL subrectangular (rather than subtriangular). In  C. cordylinaall endosomal spicules are more elongate and slender and PES curves away from the base and then back toward DES1 and DES2 (figs. 31D, F, 32F); DES2 possesses a distinctive splayed apex on the longer branch (fig. 31D), and DES1 has only a small lobe below the bifurcation point and is then divided with slender serrate branches (figs. 31E, 32F). Due to the large body size and distinctive yellow wing membrane venation, this species is easily distinguished from the other species with which it cooccurs,  C. parawirraand  C. silveirae. 1995-10-31 AMNH, SAMA Schuh & Cassis & Gross & Field ID Australia 250 -34.70001 Williamstown 456 138.85 123 123 PBI 00002453 1 1 South Australia holotype
