DESCRIPTION. Major worker ( Fig. 1A–C View Fig ). Head, in full-face view, subrectangular,
longer than broad, almost parallel sides, posterior cephalic margin shallowly concave medially, and posterolateral corner roundly convex; cephalic median furrow developed,
extending anteriad to posterior one third of head length; in dorsal view, posterior one third of head with irregular transvers striation, anterior two third of head with longitudinal striation;
lateral (area below eye) face of head somewhat smooth and shiny; dorsum of head covered entirely with sparse erect hairs mixed with dense short decumbent hairs; mandible short, subtriangular, smooth and shiny; mandible with sparse decumbent hairs; anterior clypeal margin weakly convex; median portion of clypeus smooth and shiny; frontal lobe poorly developed,
only partly covering antennal socket; frontal carina inconspicuous; eye relatively small, with
12–13 ommatidia, located at anterior one third of head length laterally; antenna 11-segmented with 2-segmented club; antennal scape thin (clavate, its apical portion almost as long as antennal segments X) and short, when laid backward reaching posterior one third of head length;
scape somewhat smooth and shiny, covered with dense decumbent hairs.
profile; B – dorsal view of body; C – head in full-face view.
Mesosoma smaller than head and gaster; promesonotum strongly convex to form a dome,
mesosonotum slope to metanotal groove, with sparse erect hairs mixed with dense short decumbent hairs; promesonotal suture present as carina dorsally; pronotal dorsum wrinkled but slightly shiny, lateral face of pronotum smooth and shiny; mesonotum smooth and shiny;
mesopleuron punctate, clearly demarcated from metapleuron by deep groove; metanotal groove distinct; propodeal spine, in profile, relatively short and subtriangular, pointed posterolaterally; in profile view, propodeum distinctly lower than promesonotum, its dorsal outline almost straight; propodeum entirely punctate; entire mesosoma without erect hairs;
legs entirely with numerous short decumbent hairs, smooth and shiny.
Petiole, in profile, with long anterior pedicel, punctate and without hairs; petiolar node,
in profile, relatively short, shorter than high, its lateral face micropunctate, while dorsal face smooth and superficially shagreened with smooth and shiny interspaces, with 4–5 erect hairs;
postpetiole clearly shorter than broad, its dorsal outline weakly convex, and entirely finely punctate; in dorsal view, postpetiole rounded; postpetiole with 4–6 erect hairs.
Gaster larger than head and elliptical; gastral tergite I smooth and shiny, and covered with dense erect hairs mixed with dense short decumbent hairs; anterior margin of gastral tergite I feebly concave.
Head, mesosoma and waist (petiole and pospetiole) reddish brown; gaster dark brown;
antenna and legs yellowish brown.
Minor worker ( Fig. 2A–C View Fig ). Head, in full-face view, longer than broad, lateral margin weakly convex and posterior cephalic margin almost straight; head entirely smooth and shiny; dorsum of head entirely covered with dense short decumbent hairs, a pair of erect hairs on frons, and a pair of erect hairs on frontal carinae; mandible short, subtriangular,
smooth and shiny; clypeus entirely smooth and shiny, its anterior clypeal margin roundly convex; frontal lobe poorly developed, only partly covering antennal socket; frontal carina inconspicuous, reaching level of eye; eye relatively small, with one ommatidium, located at anterior ¼ of head length laterally; antenna 11-segmented with 2-segmented club; antennal scape thin (clavate, its apical portion almost as broad as antennal segment X), when laid backward extending slightly beyond posterolateral corner of head; scape somewhat smooth and shiny, with dense decumbent hairs.
Mesosoma narrower than head and gaster; promesonotum strongly convex to form a dome,
mesonotum slope to metanotal groove, with dense short decumbent hairs; promesonotal suture absent, promesonotum entirely smooth and shiny; mesopleuron finely punctate, clearly demarcated from metapleuron by deep groove; metanotal groove distinct; metapleuron not demarcated with lateral face of propodeum, largely smooth and shiny; propodeal spine absent, in profile view, propodeum distinctly lower than promesonotum, its dorsal outline weakly convex; propodeal junction convex; declivity of propodeum shallowly concave,
marginated laterally by thin rim; dorsum of propodeum smooth and shiny, its lateral face punctate posteriorly; entire mesosoma without erect hairs; legs entirely with numerous short decumbent hairs, smooth and shiny.
Petiole, in profile, with long anterior pedicel, micropunctate and without hairs; petiolar node, in profile, shorter than high, convex dorsal outline, smooth and shiny, with 2–4 erect hairs; postpetiole in profile view, almost flat, with weakly convex dorsal outline, smooth and shiny, with 2–4 erect hairs.
Gaster larger than head; gastral tergite I smooth and shiny, and covered with dense short decumbent hairs mixed with sparse erect hairs; anterior margin of gastral tergite I feebly concave. Body yellowish brown.
DIAGNOSIS. New species is most similar to C. 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: 1) in major workers, frons, vertex dorsa of petiole and postpetiole and first gastral tergite with dense erect hairs (without erect hairs in C. pygmaea );
2) 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 ).
HABITAT. The type series was collected from a cave at twilight zone about 3 m from the entrance.

DISTRIBUTION. Thailand (Kanchanaburi Province) .
ETYMOLOGY. The specific name is dedicated to Professor Somsak Panha (the Director of the Higher Education Commission and Centre of Excellence on Biodiversity, Chulalongkorn
University), a famous taxonomist in Thailand, who is dedicated to karst and cave biodiversity and conservation in the country and kindly supported us in field surveys.
