Identification

  • longideclivis. Camponotus longideclivis McArthur, in McArthur & Adams, 1996: 31, fig. 23 (s.w.) AUSTRALIA.

Description

Worker

Colour: head and scapes dark brown, funiculus, mesosoma and node lighter red brown, posterior gaster black, anterior gaster red brown; coxa and femurs and tibia lighter than mesosoma, more yellowish, tarsi darker, more brownish. PD: D in largest major workers about 1·2 (Fig. 11b), ratio greater in minor workers (Fig. 23a). Pilosity: absent on gula, 15-20 to 0.5 mm long on pronotum, less on mesonotum and 4-8 on propodeum, plentiful on gaster pointing backwards, short setae on scaprs raised to 20°, short setae on midtibiae raised to 30°. Pubescence: on dorsum of mcsosoma and head adprcssed setae < 0.1 mm long, spaced >> length. Integument finely reticulate, glossy. Node summit viewed from rear: flatly convex. Metanotum feeble or obsolete in major workers, obsolete in minor workers.

HW = 1.70-3.70 mm; TL = 2.38-3.08 mm; n = 23. TL = 2.03 + 1.78 Jog HW (n = 23, r = 0.94, s.e.(y), = 0.10, s.e.(x), = 0.05). PD: D = 1-2 in major workers increasing to 2-5 in minor workers. HW:HL= < 1.0.

Type Material

Holotype. One major worker (pinned) South Australian Museum plus paratypes in alcohol, SAMA, Australian National Insect Collection, Western Australian Museum. Collected by A. J. and W. M. McArthur. July 1993, from under a rock at eastern corner of Granite outcrop, Peak Charles, north of Esperance, Western Australia.

Etymology

The specific name is derived from lange (Latin: length) and declive (Latin: a slope or declivity) because the declining face of the propodeum is distinctly longer than that of its near relative, Camponotus consobrinus.
