Camponotus longideclivis

The type material was found "under a rock at eastern corner of Granite outcrop."

Identification
A member of the Camponotus nigriceps species group. McArthur and Adams (1996) - Distinguished from Camponotus consobrinus by the ratio PD: D of major workers where the mesosoma of C. longideclivis is distinctly higher than C. consobrinus.

Distribution based on Regional Taxon Lists
Australasian Region: Australia.

Nomenclature

 * . Camponotus longideclivis McArthur, in McArthur & Adams, 1996: 31, fig. 23 (s.w.) AUSTRALIA (Western Australia).
 * Status as species: McArthur, 2007a: 306; Heterick, 2009: 62; McArthur, 2014: 88.

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) plus paratypes in alcohol, SAMA,,. 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.
