Camponotus paraleonardi

Recorded from Phang-nga Province in Thailand and from Mandalay Division in Myanmar.

Identification
Minor worker: Black species with brown antennae and legs; long pale standing setae abundant all over dorsum; dense golden pubescence on dorsum of mesosoma and on gaster tergites characteristic. Vertex elevated. Clypeus basally with small emargination at middle. Flagellum of normal length. Pronotum with reduced sculpture, somewhat shiny. Dorsal outline of pronotum moderately convex, of mesonotum and propodeum almost straight, propodeum gently downcurved. Petiolar node high and narrow in lateral aspect.

Major worker unknown.

This species can be easily recognized by the dense golden pubescence on the dorsal mesosoma and gastral tergites, which makes it very similar to Colobopsis leonardi. The single specimen from Myanmar differs by a yellowish base of the scape and shows fewer setae dorsally on the head, but is supposedly conspecific.

Paratypes (n = 2): HW 1.22, 1.24; HL 1.39, 1.48; SL 1.36, 1.39; SW 0.15, 0.16; EL 0.38, 0.44; ML 1.89, 1.96; HaL 0.30, 0.35; FeL 1.37, 1.70; CI 82, 89; SI 110, 114; EI 31, 37; FeI 111, 139. Ward’s Indices: ASM/HWex 0.36, 0.30; ASM/CLW 0.67, 0.61; CLW/CLL 1.33.

Structures: Head roundish, uniformly reticulated and matt dorsally and laterally, with slightly reduced microsculpture and somewhat shiny ventrally. Lateral outline of eye and head contiguous. Vertex raised. Frons and basal half of clypeus with shiny midline. Clypeus with very small emargination at middle of basal margin, distal margin slightly protruded in middle. Mesosoma slender and low, densely reticulated and matt except for slightly shiny pronotum where reticulation is weakly developed; dorsal outline of pronotum and posterior slope of propodeum moderately convex, of mesonotum and anterior part of propodeum almost straight. Petiole with high node, its anterior and posterior face parallel, apex obliquely truncated. Gaster tergites with dense reticulation.

Pilosity: Long standing setae abundant all over dorsum, of white or pale yellow colour, longest on pronotum and propodeum. Pubescence very dense, golden to yellow on dorsum of mesosoma and on gaster tergites, on other parts pale yellowish and sparse, very short on dorsum of head.

Colour: Trunk black; translucent margins on tergites 3 and 4 very narrow, hardly discernable. Antenna and legs dark brown; scape lighter, pale to medium brown.

Variation: The worker from Myanmar differs in some characters, but is considered as conspecific: base of scape yellowish; vertex of head less convex (but head of this specimen deformed); dorsal outline of mesonotum and propodeum very straight.
