Strumigenys pilosa

Nothing is known about the biology of .

Identification
Zhou (2001) - Resembles Strumigenys lacunosa, but differs from the latter in head and alitrunk with much more flagellate hairs; 2 spiniform teeth of apical fork of mandible· without intercalary denticle; there are several longitudinal striations among sculptures on alitrunk and the postpetiolar disc. Besides, the new species larger in size compared with the measurements: of the latter.

Anterior clypeal margin straight. Antennae 6 segments; 2nd segment 2 X as long as broad, 3rd and 4th segments about as long as broad, 5th segment 3 X as long as broad, terminal segment 4 X as long as broad; all segments in a ratio of about 12 : 2. 5 : 1 : 1 : 4 : 8. Eyes small, with 13 ommatidia. Alitrunk shorter than head, sutures distinct. Dorsal outline of pronotum flattened, mesonotum oblique backward; basal face of propodeum as long as declivity; propodeal spines developed, triangular, broad at base. Petiolar node swollen but not highly convex, with a long peduncle; spongiform appendages relatively developed.

Mandibles with sparse punctures; punctures on antennal scapes dense and fine; clypeus, head, alitrunk, petiole and postpetiole with lacunose sculptures; sculptures on head coarser, there are several longitudinal striations among sculptures on alitrunk and postpetiolar disc; parts of mesopleura and metapleura smooth and shining; gaster smooth and shining, base of first segment with short striations. Head with 6 pairs of flagellate hairs, dorsum of pronotum and mesonotum with 9 flagellate hairs, propodeum with abundant flagellate hairs which slightly shorter than those on pronotum or mesonotum; petiole, postpetiole and gaster with abundant flagellate hairs. Flagellate hairs on head and alitrunk mixed up with abundant decumbent hairs.
