Types. Holotype, ♂, AUSTRALIA, Qld: Cougal Creek, Upper Tallebudgera, 80m, 28°12’S 153°21’E, rainforest, 12–14.x.1990 (G. Daniels) (UQIC55277 QM). Paratypes, Qld: 1 ♀, same data as holotype (QM); 1 ♂, Nagarijoon Falls, Lamington Nat. Park, S. Qld, 28.x.1955 (J. Stoodley) (QM); 1 ♀ and 1 ♂ or ♀ (abdomen missing, body length indicates female), Lamington Nat. Park, 29.x.1955 (F.A. Perkins) (QM).

Etymology. Named after the type locality, Cougal Creek.

Diagnosis. This species can be distinguished from C. obscurus by the presence of darkened areas around the pterostigma, along the hind margin of the forewing and in most cases on the mesonotum, a brown pterostigma and a phallotheca bearing two spines ventrally to left-laterally, one of which is almost twice as long as the other.

Colour. Body light brownish-yellow (testaceous), sometimes with an orange or greenish tinge; lateral parts of mesonotum, abdominal sternites, eyes and antennae slightly to distinctly darker. Forewing hyaline with testaceous veins and tubercles; pterostigma mid to dark brown; posterior margin including apical veins and cells darker i.e. distad of apex of clavus.

Morphology. Body length: ♂ 4.7–5.3 mm; ♀ 5.2–5.7 mm.

Head: Vertex 1.5–1.8 x wider than long; apical carina v-shaped, subapical carina u- or v-shaped; median carina of vertex absent or if present, covering up ½ of basal compartment of vertex; basal compartment 2.3–5.3 x longer than apical compartment. Frons 1.4–2.0 x longer than wide. Postclypeus with median carina evanescent; lateral carinae absent or evanescent. Anteclypeus with median carina absent or evanescent; lateral carinae absent. Rostrum very short, reaching mid femur but not hind coxa; apical segment of rostrum shorter than subapical segment.

Thorax: Forewing 3.3–3.4 x longer than wide; costal margin with about 3–7 tubercles; Sc+R+M near basal cell fused, forming a minute common stem Sc+R+M or Sc+R fused, M emerging separately from basal cell; fork of ScRA+ RP distad or at same level as fork CuA1+CuA2; position of r-m basad of fork MA+MP; MP apically bifid; vein delimiting subapical cell C4 distinctly distad of vein delimiting C5; subapical cell C5 shorter than C4; CuA2 ending well before it reaches margin of wing; 8 apical cells; 5 anteapical cells. Hind leg: 1st tarsomere with 7 apical teeth and no platellae; 2nd tarsomere with 8 apical teeth and 4 platellae.

Male genitalia: Anal tube as in Figs 5 C,D. Pygofer and genital styles as in Figs 5 E,F. Aedeagus ( Figs 5 A,B): Phallotheca ventrally to left-laterally with two large, curved spines, unequal in length, with spine (b) almost twice as long as spine (a); spine (a) arising near apex of aedeagus and spine (b) arising right underneath spine (a). Flagellum unarmed.

Female genitalia: Ovipositor, wax plate and anal tube as in Figs 6 D–F: wax plate circular to oval shaped; anal tube trapezoid, apex much wider than base.
