Parasyscia foveolata

The types were collected from litter in secondary tropical forest.

Identification
C. foveolatus most closely resembles Parasyscia indica and Parasyscia dohertyi. Differs from indicus by transversal petiole node (PTI accordingly 0.62 and more than 1.0), smaller eyes (EL 0.11 and 0.19-0.26 mm), shorter antennal scapes (SI 56and more than 75) and presence of dense subdecumbent pubescence on the petiolar and postpetiolar nodes and gaster. Differs from C. doherthyi by sculpture of alitrunk and from both species by smaller size. (Radchenko 1993)

Worker
Dimensions (in mm). Holotype worker: AL 0.91; HL 0.62; HW 0.57; SL 0.32; ED 0.11; PTL 0.25; PTW 0.41; PPTL 0.43; PPTW 0.55.

Head slightly elongate (CI 93), sides and occipital border feebly convex. Occipital corners with rounded lobes. Eyes small (OI 18), placed below the middle of the head. Anterior clypeal border straight, without prominent lobe. Scapes short (SI 56) barely reach posterior margin of eyes. Entirely head densely foveolate, spaces between them smooth. Petiolar node broader than long, has a sharp, raised anterodorsal and posterodorsal margins, the posterodorsal margin of postpetiole is also sharply raised. Propodeal declivity slightly concave, surrounded by a sharp, semicircular margin. Subpetiolar process in side view rectangular. Sides of alitrunk and entire of petiole and postpetiole densely foveolate, spaces between the foveolae on the sides of the alitrunk smooth and shining, on the postpetiole with a microsculpture. Foveolae on the dorsum of alitrunk smaller than on its sides, spaces between the foveolae are wider, approximately equal on the foveolae themselves. First tergite sparsely punctured, the surface between punctures smooth and shining. Entirely nodes and gaster with dense short subdecumbent pubescence and numerous straight erect hairs; alitrunk and head with erect hairs only. Colour entirely yellowish-red.
