Camponotus eastwoodi

Mutual relationship with Ogyris spp. (Lepidoptera: Lycaenidae) (R. Eastwood, personal communication).

Identification
A member of the Camponotus nigriceps species group. McArthur and Adams (1996) - Similar in appearance to Camponotus loweryi and Camponotus nigriceps. Gula setae in C. eastwoodi sparse in major workers, slightly more plentiful in minor workers; whereas in C. nigriceps dense in minor workers; in C. loweryi absent. Head sides of smallest workers tapering to the rear.

Distribution

Nomenclature

 *  eastwoodi. Camponotus eastwoodi McArthur, in McArthur & Adams, 1996: 29, fig. 21 (s.w.) AUSTRALIA.

Worker
Colour: head black or very dark brown with lighter patches, mesosoma, node, coxa and femur honey coloured or light brown or yellow, gaster usually the same colour or slightly darker, tibia and tarsi red brown. Pilosity: up to 0·4 mm long plentiful on pronotum, less on mesonotum and 5-10 on propodeurn (Fig. 21 a, b), on gaster plentiful pointing backwards; on gula shorter, sparse in major workers sometimes absent, usually present but sparse in other workers, short setae on scapes raised to 10°, short setae on midtibiae raised to 10°. Pubescence: ad pressed setae about 0.1 mm long, spaced < length, scarcely visible on the dorsum of mesosoma, sparse on head. Integument finely reticulate, glossy. Node summit viewed from rear: convex or flat in major workers, convex in other workers. Metanotum usually distinct in major workers.

HW = 1.60-3.80 mm; TL = 2.65-3.40 mm; n = 17. In smallest minor workers where HW < 1.8 mm, the head sides taper to the rear; HW (at mandibles) minus HW (at vertex) is often > 0.1 mm. TL = 2.46 + 1.70 log HW (n = 17, r = 0.95, s.e.(y) = 0.06, s.e.(x), = 0.10). PD: D = 1.0 increasing to 3.0 in minor workers. HW: HL in major workers often reaches 1.0 when HW exceeds 3.7 mm.

Type Material
Holoyype. One major worker (pinned) plus paratypes in alcohol, SAMA,. Collected by Mr Rod Eastwood, Nov. 1993, from Leslie Dam, Eatonsville, South Grafton, New South Wales.



Etymology
