The type series was collected from a cave at twilight zone about 3m from the entrance.
Identification
New species is most similar to Carebara pygmaea. Both species share the following characteristics of major workers:
- frons with longitudinal striation, while vertex with transverse striation
- frontal carinae with 3 pairs of erect hairs
- masticatory margin with 5 teeth (including large apical tooth)
- antenna 11-segmented with 2-segmented club
- promesonotum in profile view distinctly convex to form a dome
- promesonotal suture indistinct
- propodeal spine short, usually shorter than its base.
However, C. panhai can be easily distinguished from C. pygmaea by the following characteristics:
- in major workers, frons, vertex dorsa of petiole and post-petiole and first gastral tergite with dense erect hairs (without erect hairs in C. pygmaea)
- lateral face of pronotum largely smooth and shiny (punctate and reticulate in C. pygmaea)
- propodeum in minor workers largely smooth and shiny (entirely punctate in C. pygmaea).
Wimolsuthiku et al. (2024)
Major (Fig. 6): head and gastral tergite I with dense erect hairs mixed with decumbent hairs; promesonotum with sparse short 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. 12–13 ommatidia; gastral tergite I somewhat smooth and shiny.
Minor (Fig. 7): propodeal dorsum smooth and shiny; petiole and postpetiole with 2–4 erect hairs; propodeal junction roundly convex; body yellowish.
Carebara panhai is most closely related to Carebara bokorensis and Carebara parva, but can be separated from C. bokorensis by the following characteristics in the major worker:
- posterior one-third of head with transverse striation (punctate, without striation in C. bokorensis)
- gastral tergite I smooth and shiny (with dense foveae in C. bokorensis, see Fig. 3C and Fig. 6C for comparison)
- head and promesonotum with sparse erect and decumbent hairs (dense hairs in C. bokorensis, see Fig. 3 and Fig. 6 for comparison).
For the difference between C. panhai and C. parva, see C. parva.
Minor workers of C. panhai can be separated from other members of the species group by:
- dorsa of petiole and postpetiole each with 2–4 erect hairs (without erect hairs in other species)
- propodeal junction roundly convex (blunt angle in C. parva and C. adisaki).
