Leptomyrmex dolichoscapus

Identification
Head elongated head (CI less than 79), antennal scape very elongated (SI greater than 220) and extending beyond the vertex of the head by 2/3 their length. Palps very long. Anterior mesonotum with a weak “bump”. Pilosity short adpressed hairs. Sympatric with Leptomyrmex garretti but readily separated from it by the extremely long scapes of L. dolichoscapus.

Worker
In full face view vertex of head convex, rounding into sides of head, sides of head weakly rounded, widest at mid-length, eyes placed at mid-length of head capsule. Palps long extending to posterior of head capsule or just beyond. Pronotum above level of promesonotal suture, posterior margin of pronotum rounding sharply to the suture; anterior portion of the mesonotum initially in same plane as pronotum then rounding sharply into descending plane of remainder of mesonotum (Fig. 8) producing a weakly raised anterior mesonotal “bump”. Legs long; hind tibial spurs with reduced barbules, barbules absent from basal ¼. Dark brown in colour.
