Description

(Figs 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12)

Female. Body length: 1.00 mm (Fig. 9: Lectotype - length approximate as specimen is dissected and crushed).

Colour. Fig. 2. Ground colour cream/off-white. Two broad longitudinal stripes on mesoscutum, extending to scutellum, propodeum laterally, and most of gaster, golden brown. Darker pigmentation on ocelli, notauli, hind tibia and tarsus. Wings hyaline.

Morphology

Head. Frons and antennal scrobes with very fine reticulate sculpture, frons below ocellar triangle with dense robust setae. Maxillary palp two-segmented. Antenna (Figs 3, 4) with radicle 2.1 × as long as wide. Scape 4.0 × as long as wide, 3.3 × as long as radicle, and 2.2 × as long as pedicel, flagellum with four flagellom-eres; F1 and F2 combined length longer than F3, F3 1.3 × as wide as long, much shorter than pedicel plus F1 and F2, and 0.3 × as long as clava; clava with 8-9 multiporous plate sensilla (mps - Fig. 4). Clava with an obliquely truncate apex with numerous basiconic peg sensilla (Fig. 4). Clava 2.1 × as long as wide; mps 0.3 × length of clava.

Mesosoma. Lateral lobe of mesoscutum with two setae (Fig. 5). Mid lobe of mesoscutum with approximately 13 pairs of setae (Fig. 5) and reticulate sculpture. Scutellum with two pairs of setae (Fig. 5). Fore tibial calcar 0.8 × length of basitarsus. Fore wing (Fig. 6) uniformly hyaline, 2.3 × as long as broad; longest seta of posterior marginal fringe 0.1 × width of wing; marginal vein with row of six long setae along anterior margin; discal setation relatively uniform. Submarginal vein with row of four long setae along anterior margin. Hind wing 3.8 × as long as broad, posterior marginal fringe 0.3 × width of wing; discal setation relatively uniform.

Metasoma. Ovipositor (Fig. 5) 7.7 × as long as hind basitarsus. Third valvula approximately 0.2x total ovipositor length.

Male. Body length generally 0.8x that of female. Colour and morphology similar to female. Antenna (Fig. 7) with scape shorter and broader than in female (cf Figs 3, 7). Genitalia as in Fig. 8.

Host. Gonipterus sp. ( Coleoptera : Curculionidae ). Based on the type locality of C. damoni (Queensland), the host species is likely to be one of the new species mentioned in Mapondera et al. 2012.

Diagnosis

Centrodora damoni can be distinguished from the other 11 Australian species in the genus by the following combination of characters: Two broad longitudinal stripes on mesoscutum, extending to scutellum; ovipositor less than half total body length (excluding head); apex of antennal clava broadly rounded; fore wing with linea calva present.

Distribution

Australia: ACT, Queensland, Tasmania (probably widespread).
