Worker description
Major. - Head in lateral view not or hardly impressed on vertex; posterior concavity of head in full-face view usually shallow; frons and anterior part of vertex rugose longitudinally; posterior part of vertex and dorsal face of vertexal lobe rugoso-reticulate, with interspaces weakly punctured; frontal carina conspicuous; antennal scrobe inconspicuous or shallowly impressed; clypeus without a median longitudinal carina; median and submedian processes of hypostoma absent or present but inconspicuous; lateral processes conspicuous; antenna with a 3-segmented club; maximal diameter of eye almost as long as or shorter than antennal segment X. Promesonotal dome in dorsal view largely smooth, or sparsely sculptured with weak transverse rugulae, in lateral view with a low to conspicuous mound on its posterior slope; humerus not produced; the dome much narrower at the humeri than at the bottom; mesopleuron, metapleuron and lateral face of propodeum well punctured, sometimes overlain with weak rugulae; propodeal spine narrowly based, usually slightly curved apically. Petiole longer than postpetiole (excluding helcium); postpetiole not massive. First gastral tergite smooth and shining entirely, or sometimes shagreened around its articulation with postpetiole.
Minor. - Frons and vertex smooth and shining, or rarely shagreened or very weakly rugoso-punctate; area between antennal insertion and eye weakly rugoso-punctate; preoccipital carina conspicuous dorsally and laterally; median part of clypeus smooth, without a median longitudinal carina; antenna with a 3-segmented club; scape extending far beyond posterolateral margin of head; maximal diameter of eye much shorter than antennal segment X. Promesonotal dome largely smooth and shining, but sometimes weakly rugoso-punctate dorsolaterally, in lateral view with a low or inconspicuous mound on its gentle posterior slope; humerus of the dome in dorsal-oblique view not produced; mesopleuron, metapleuron and lateral face of propodeum well punctured; propodeal spine elongate-triangular, directing upward. Petiole (a little) longer than postpetiole (excluding helcium); postpetiole not massive.
Recognition: This medium-sized species with general habitus is similar to Pheidole binghamii Forel HNS , P. elongicephala HNS sp.n., P. indica Mayr HNS , P. ochracea HNS sp.n. and P. plagiaria F. Smith HNS among Indo-Chinese species. P. fervens HNS is well separated from P. indica HNS which has the following characteristics: eye relatively large (maximal diameter of eye much longer than antennal segment X in the major, and as long as or a little longer than X in the minor); in the major propodeal spine is relatively broadly based (see Eguchi 2004).
Posterior margin of head in full-face view is more deeply and narrowly concave in the major of P. binghamii, HNS P. elongicephala HNS and P. ochracea HNS than in that of P. fervens HNS , and sculpture on dorsum of vertexal lobe is usually stronger in the major of the former three.
The major of P fervens HNS is separated from that of P. plagiaria HNS which has the following characteristics: posterior margin of head in full-face view deeply concave; the rugulae running almost transversely along posterior margin of vertexal lobe.
Distribution & bionomics: Known from N. Vietnam, Manchurian subregion (southern part only), Oriental region, Austro-Malayan subregion, W. Pacific and West coast of N. America. In the Indo-Malayan subregion this species is one of the prevailing Pheidole HNS species in semiurban and rural areas.
