Identification
Bolton (2000) - A member of the Strumigenys appretiata-group. Within the group four species (glenognatha , Strumigenys halosis, Strumigenys raptans, Strumigenys wheeleriana) combine the presence of a distinct ventral postpetiolar spongiform lobe with very short basigastral costulae (much shorter than dorsal length of postpetiole disc), unsculptured first gastral tergite and presence of humeral hairs. Of these wheeleriana alone has the lateral petiolar lobes reduced to minute oblique cuticular denticles that are limited to the extreme posterolateral angles of the node in dorsal view. In the other three species the lobes are triangular or bluntly rounded and are either laminate and translucent or weakly spongiform. S. halosis and raptans are larger species (HL 0.55- 0.59, HW 0.48-0.54) with long fine hairs on the first gastral tergite that are markedly curved or even flexuous to subflagellate. S. glenognatha is smaller (HL 0.43-0.48, HW 0.40-0.44) and its first gastral tergite has sparse standing hairs that are short and straight to very weakly curved, not flexuous.

Description
Worker
Holotype. TL 1.7, HL 0.46, HW 0.42, CI 91, ML 0.06, MI 13, SL 0.18, SI 43, PW 0.23, AL 0.44. Pronotal humeral hair long and fine. Mesonotum with a single pair of shorter standing hairs. First gastral tergite with sparse standing hairs that are straight to shallowly curved, not flexuous. Pronotal dorsum glossy, with some feeble longitudinal costulae; this sculpture repeated somewhat more distinctly on mesonotum. Propodeal spines elongate and narrow, acute apically. Petiole node in dorsal view as long as broad or slightly longer than broad, not conspicuously transverse. Lateral lobes of petiole narrow, restricted to posterior half of side but strongly projecting laterally, each one longer than half the width of the disc. Anterior margin of postpetiole disc transverse or at most only minutely concave; lateral margins of disc conspicuously convergent posteriorly. Ventral spongiform lobe of postpetiole large and distinct in profile but not visible in dorsal view as it is completely overhung by the broadly flaring lateral spongiform lobe. Basigastral costulae short, sharply defined, distinctly shorter than maxi mum length of postpetiole disc.
Paratype. TL 1.6, HL 0.43, HW 0.40, CI 93, ML 0.06, MI 14, SL 0.18, SI 45, PW 0.21, AL 0.42.
