Identification
Major
Head and gastral tergite I with sparse erect hairs; promesonotum without erect hairs; with head in full-face view, posterior one-third with transverse striation, while anterior two-thirds with longitudinal striation; eye small, with ca. 10 ommatidia; gastral tergite I superficially shagreened with smooth and shiny interspaces; propodeal spine shorter than diameter of propodeal spiracle.
Minor
Propodeal dorsum smooth and shiny; petiole and postpetiole with decumbent hairs; propodeal junction bluntly angulate; body reddish brown.
Carebara adisaki is most closely related to Carebara parva and Carebara bokorensis. It can be separated from C. bokorensis by the following characteristics in the major worker:
- posterior one-third of head dorsum with transverse striation (without striation in C. bokorensis)
- gastral tergite I superficially shagreened and shiny (punctate in C. bokorensis, see Fig. 1A and Fig. 3A for comparison)
- posterior half of head dorsum and promesonotal dorsum without erect and decumbent hairs (dense hairs present in C. bokorensis, see 1A and Figs. 3A for comparison).
This species can be separated from C. parva in the major worker by:
- propodeal spine shorter than diameter of propodeal spiracle (as long as or slightly longer than diameter of propodeal spiracle in C. parva)
- first gastral tergite with erect hairs along its posterior margin only (erect hairs covering entire segment in C. parva).
Minor worker of C. adisaki is similar to C. parva in having a smooth and shining propodeal dorsum, without erect hairs on petiole and postpetiole, and the blunt angle propodeal junction. However, C. adisaki is separated from C. parva by:
- larger species (HW 0.43–0.46 mm in C. adisaki; HW 0.36–0.40 mm in C. parva)
- body colour darker (reddish brown in C. adisaki; yellowish brown in C. parva)
