broad as long with maximum diameter in the posterior third. Occipi- 
tal margin moderately concave; eyes situated close beyond the 
midlength of the sides of the head. Scapes project behind the occipi- 
tal margin by about one third of their length. Apical antennal flagel- 
lum slightly thickened. Promesonotal dorsum broadly rounded with 
deep promesonotal suture. Deep impression between promesono- 
tum and propodeum, with two raised stigmata on the ground. Dor- 
sal propodeum in profile slightly convex, forming almost a right 
angle with declivity which is almost straight. Petiolar scale in profile 
cone shaped. Gaster oval, tibiae cylindrical, not thickened and 
without spines. Cuticular surface weakly reticulated and slightly 
opaque, covered with punctures which are particularly dense and 
elongated on gaster. Decumbent pubescence very fine, yellowish, 
distributed over the whole body, including tibiae and scapes, espe- 
cially dense on gaster. Uniformly dirty yellow brown; tarsi, apical 
antennal flagellum and front head reddish to yellow red. Hayvep, 
Borneo. 
Camponotus exsectus Emery 
Camponotus exsectus Emery, 1901 : 53. Syntype $$ and Museo Civico di Storia 
Naturale, Genova (examined). 
Original description (Emery, 1901): workers dirty yellow, shining, 
front head and gaster lighter, segment borders brownish, decumbent 
pubescence denser on head and alitrunk than on gaster. Body, 
including scapes and legs, covered with longer, whitish, erect hairs. 
Weak cuticular punctures on the whole body, those of the gaster 
elongated. Head rounded and convex. Clypeus weakly convex and 
not carinated; anterior clypeal margin with wide excision in the 
middle third, and indented edges. Mandibles strongly curved on 
outside and 5 teeth on inside. Frontal carinae almost straight, linea 
frontalis weak, but clearly visible. Scapes project beyond occipital 
margin by about one third of their length. Viewed in profile, pro- 
and mesonotum form a curved line which is connected to the pro- 
podeal outline by an obtuse angle. Propodeal profile broadly 
rounded. Scale biconvex, tapering into a sharp transverse ridge. 
Length: 4-3/4 to 5-1/2 mm. 
According to my own examination, workers are more shining 
than those of C. texens, but not as much as those of C. gombaki.
