Leptogenys johary

Individual workers of this species have been discovered foraging on the forest floor and in leaf litter. One nest was found under a rock.

Identification
A member of the attenuata species group. Rakotonirina and Fisher (2014) - Worker. Third antennal segment twice as long as second segment; eye large, maximum diameter about one-fourth the length of lateral cephalic margin; breaking line of side of head; in dorsal view, mesonotum broader than long and petiolar node remarkably elongate and strongly narrowed anteriorly.

Distribution
The northernmost range of L. johary in Madagascar is limited to the montane rainforest of the PN Masoala between 800–897 m, Amparihibe at 846 m, and the rainforest of Makira between 470–600 m. The southernmost distribution of this species is restricted to the RNI Betampona at an elevational range of 525–550 m and the FC Didy at 960 m.

Worker
(8 specimens). HW: 0.95–0.98, HL: 1.38–1.47, CI: 66–69, SL: 1.37–1.48, SI: 143–153, PW: 0.74–0.83, WL: 2.21–2.33, PNH: 0.57–0.60, PNL: 0.73–0.80, PNW: 0.41–0.43, DNI: 51–57, LNI: 73–77.

Head elongate, very slightly diverging anteriorly, sides subparallel; posterior margin weakly concave. Mandible basal margin with blunt angle or preapical tooth. In full-face view, eye maximum diameter roughly one fourth the length of side of head; location breaking outline of side of head. Antennal scape long, about one third of its length surpassing posterior cephalic border; third antennal segment distinctly long, twice as long as the second. In dorsal view, mesonotum broader than long. Posterolateral margin of propodeum approximately at level of propodeal spiracle with toothlike lobe; propodeal spiracle rounded. With petiole in dorsal view, node elongate, twice as long as broad and greatly narrowed anteriorly. Mandible and clypeus smooth interspersed with scattered piligerous punctures; rest of body dorsum and propodeal declivity generally smooth and shining. Standing hairs arise from very small punctures, with longer, erect hairs on head and pronotum and much shorter hairs on rest of body dorsum. Body color brown to dark brown, with lighter appendages.
