Specimen Labels

This species is known only from the type locality in Indonesia (Java). The type specimens were collected from the vine Dischidia major (Vahl) (=Dischidia rafflesiana Wallich) with Dolichoderus thoracicus.

Identification

Hosoishi and Ogata (2012) – This species is similar to Crematogaster overbecki. It differs in having a single median rugula in addition to two pairs of lateral rugulae on the clypeus, and in the pronounced sculpture on the dorsum of the mesonotum.

Description

Worker

Hosoishi and Ogata (2012) - HW 0.7-0.71; HL 0.68-0.72; CI 99-103; SL 0.49-0.53; SI 70-75; EL 0.14; PW 0.4-0.44; WL 0.62-0.63; PSL 0.1-0.11; PtL 0.23; PtW 0.19-0.21; PtH 0.15; PpL 0.12-0.13; PpW 0.19-0.2; PtHI 65; PtWI 91; PpWI 154-158; WI 95-100 (Lectotype and one paralectotype workers measured).

Compound eyes slightly projecting from lateral margin of head. Scape reaching posterior corner of head, the scape with standing and appressed setae. Pronotal shoulders developed as ridges. Mesonotal dorsum convex in lateral view. Metanotal groove concave.

Propodeal spines longer than the diameter of propodeal spiracles, curved upward. Anterior margin of metapleural gland bulla not reaching anterior margin of propodeal spiracle.

Petiole in dorsal view rectangular with angular corners. Subpetiolar process not visible in the specimens examined. Postpetiole bilobed behind, but without distinct longitudinal median sulcus.

Dorsal surface of head generally smooth, but the malar region with longitudinal rugulae. Clypeus with one median and two distinct pairs of lateral rugulae. The rugulae connecting the anterior and posteror clypeal margins. Dorsal face of promesonotum with dense reticulate sculpture. Lateral surface of pronotum generally smooth and shining, but some longitudinal rugulae extending from the anterior portion of the pronotum. Mesopleuron smooth, but lower portion of mesopleuron weakly sculptured. Longitudinal rugulae developed on the front and behind the metanotal groove in lateral view.

Fourth abdominal tergite with abundant appressed setae and sparse standing setae.

Type Material

Hosoishi and Ogata (2012) – LECTOTYPE worker (top specimen of two on one pin) (by present designation) and one paralectotype worker, one paralectotype queen, four paralectotype males from INDONESIA: Buitenzorg [Bogor, Java] (Conte Solms Laubach) (Museo Civico di Storia Naturale, Genoa) [examined].
