Strumigenys gunter

Identification
Strumigenys gunter is a small shiny pale-yellow species with small eyes of one to several facets, abundant long flexous hairs on metasomal dorsum, and shorter subdecumbent hairs on the promesonotum. It morphologically similar to a cluster of species related to Strumigenys chernovi, but is immediately distinguished by the smaller eyes. Additional diagnostic notes are given under S. chernovi. Strumigenys gunter is only known from three worker specimens collected on Gau and Koro.

Description
Worker. Measurements (n = 2): TL 2.41–2.44 mm, HL 0.55–0.58 mm, HW 0.39–0.43 mm, CI 70–74, MdL 0.23–0.27 mm, MI 42–47, SL 0.37–0.41 mm, SI 81, PW 0.24–0.26 mm, PI 59–61, FL 0.37–0.41 mm, FI 94–96, EL 0.24–0.26 mm. Color a pale yellowish-brown. Mandibles long and linear with one preapical tooth; preapical tooth length approximate to maximum mandible width. Apicoscrobal hair short and simple, weakly projecting laterally but not filiform or flagellate. Cephalic dorsum uniformly reticulate-punctate. Ground pilosity of cephalic dorsum short, simple, strongly curved. Pronotal humeral hairs thin, flexuous, of moderate length. Promesonotal dorsum with short curved ground pilosity and two pairs of longer erect hairs in addition to humeral pair. Pronotal dorsum with weak longitudinal striae. Mesonotal dorsum weakly reticulate-punctate. Propodeal dorsum smooth and shining. Pronotal sides weakly striate apically; remainder of mesosomal sides smooth and shining. Propodeal tooth short, narrowly triangular, embedded in lamella. Lamella forming convex curtain along propodeal declivity. Femur and tibia of hind leg both with single filiform projecting hair on dorsal surface. Petiolar node in profile with anterior face slightly steeper and shorter than posterior face; lateral spongiform lobe small; restricted to posterior margin of node. Dorsum of petiole and petiolar disc smooth and shining; each with two pairs of filiform to flagellate hairs. Ventral lobe of postpetiole spongiform. First gastral tergite with erect filiform hairs. Basigastral sculpturing consists of broadly spaced costulae shorter in length than postpetiolar disc.
