Strumigenys liukueiensis

Chien and Lin (2015) analyzed the chemical constituents of the venom of five Taiwanese Strumigenys species: Strumigenys chuchihensis, Strumigenys formosensis, Strumigenys liukueiensis, Strumigenys minutula and Strumigenys solifontis for a chemotaxonomy study. The venom was collected from extruded stings and was thought likely to contain a mixture of poison (venom) and Dufour gland secretions. GC/MS profiles showed that three of the five species were clearly differentiated by the chemical composition of their sting secretions. Two remaining two species, S. chuchihensis and S. liukueiensis, showed chemical signatures that were not significantly different from one another.

Nomenclature

 *  liukueiensis. Strumigenys liukueiensis Terayama & Kubota, 1989: 785, figs. 18-22 (w.q.) TAIWAN. See also: Bolton, 2000: 811.

Worker
Bolton (2000) - TL 2.6, HL 0.65, HW 0.43, CI 66, ML 0.30, MI 46, SL 0.40, SI 93, PW 0.27, AL 0.71. Characters of smythiesii-complex. Apicoscrobal hair simple; anterior to this hair the upper scrobe margin with 2-3 similar but shorter freely projecting hairs and posterior to it with 3-4 similar stiff hairs. In profile cephalic dorsum with numerous inclined to erect simple hairs that arise from level of eye to occipital margin. Pronotal humeral hair stiff and simple, straight or nearly so. Pronotal dorsum with 1-2 pairs of erect simple hairs, mesonotum with 3-4 pairs, propodeal dorsum posteriorly with a short pair at about level of spiracle. Dorsum of pronotum and anterior mesonotum feebly and superficially sculptured, finely shagreenate to weakly reticulate; remainder of dorsal alitrunk almost smooth to smooth. Legs with numerous erect simple hairs: hind femur with such hairs numerous on all surfaces, dorsal (outer) surface of hind tibia with several straight erect hairs as well as curved ground-pilosity, hind basitarsus with 5 or more erect hairs on its dorsal (outer) surface. With petiole in dorsal view the node longer than broad and the lateral spongiform lobes extend almost to the anterior face of the node; in profile the lateral lobe extends anteriorly almost to the anterior face of the node. Disc of postpetiole smooth. Erect hairs on first gastral tergite longer and sub flagellate near base, but behind this tending to be shorter, straighter and simple. Basigastral costulae traverse limbus but on tergite proper are sparse and short, hardly longer than width of limbus.
