Differential diagnosis. This new species is also similar to C. davidis and C. jucunda , but the body surface heavily tomentous ( Figs. 124–125 View FIGURES 112–135 , 173–174 View FIGURES 165–179 ); punctures on pronotum are sparser ( Fig. 18 View FIGURES 6–27 ); punctures on elytral disc subcircular and larger ( Fig. 19 View FIGURES 6–27 ); tarsi are slimmer ( Fig. 34 View FIGURES 28–38 ); parameres have a different shape ( Fig. 74 View FIGURES 62–83 ).

Holotype (Male). General: Body length 18.4 mm; width 6.9 mm. Body black, elytra largely orange-red. Body surface with numerous setiferous punctures; setae yellow, stubble like. Body surface heavily tomentous, covered with khaki tomentum ( Fig. 124 View FIGURES 112–135 ). Head: Clypeus apical margin raised, frons evenly convex.

Surface tomentous, thicker in lateral portion and posterior portion. Scutellum: Subtriangular, heavily tomentous. Surface with sparse, fine, arcuate-striolate, setiferous punctures; setae short. Elytra: Subrectangular; disc largely orange-red, juxtascutellar area and elytral declivity black. Surface with abundant to sparse, fine, subcircular arcuate-striolae, setiferous punctures, denser in elytral declivity; setae short ( Fig. 19 View FIGURES 6–27 ). Disc without tomentum; elytral declivity with wide, thick lateral tomentous band; posthumeral and lateral tomentous spots absent ( Fig. 124 View FIGURES 112–135 ). Metepisternum and metepimeron: Surface heavily tomentous; with dense, arcuate-striolate, setiferous punctures; setae short. Sternum: Preprosternal apophysis robust, slightly reflexed, with cluster of long setae on the apex. Metasternum covered sparse tomentum; surface with dense, arcuate-striolate punctures. Abdomen: Shallow, longitudinal groove between abdominal sternites III–V. Abdominal sternites with dense, fine, arcuate-striolate, setiferous punctures, and sparse, fine, annulate-striolate, setiferous punctures; setae short. Surface covered with tomentum, thicker on lateral portion ( Fig. 125 View FIGURES 112–135 ). Propygidium surface heavily tomentous, with dense, setiferous punctures; setae short; terminal spiracla distinctly protruding. Pygidium: Distinctly convex. Surface heavily tomentous, with fine, round, setiferous punctures; setae short. Legs: Surface with dense, fine, sinuous striolae and arcuate, setiferous punctures; setae short. Tibiae slender. Protibia with a small, external denticle in apical portion; a blunt protrusion near middle of outer margin; apical tooth of inferior ridge elongate, blunt, curved downwards ( Fig. 34 View FIGURES 28–38 ). Mesotibia and metatibia with a small, acute protrusion near middle of outer margin; three distinct, acute protrusions in distal portion; two spurs slender, acute ( Fig. 52 View FIGURES 39–61 ). Coxa, trochanter, anterior side of profemora, posterior side of mesofemora and metafemora, dorsal side of tibiae with tomentum ( Fig. 125 View FIGURES 112–135 ). Tarsi with 4 tarsomeres, slender ( Figs. 34 View FIGURES 28–38 , 52 View FIGURES 39–61 ); propretarsi short, acute. Parameres: Elongate, outer margins convergent in medial, distal portion slightly expanded, apex obtuse in apical view; interparameral split widened ( Figs. 74–75 View FIGURES 62–83 ).

Allotype (female). Body length 20.3 mm; width 7.7 mm. Similar to holotype ( Fig. 173 View FIGURES 165–179 ).

Other paratypes. Body length 19.0–21.7 mm; width 7.1–8.1 mm. Body size and shape of juxtascutellar marking with a little variation, other characters are quite stable ( Fig. 174 View FIGURES 165–179 ).

Etymology. The species epithet comes from the Latin word for velvety in reference to the dense tomentum on the body.

Distribution. China: Hainan.

Natural history. In May 2014, several third instars, pupae and a fresh adult in cell were found in the rotten root of a large standing tree where there were large colonies of Anoplolepis gracilipes (Smith, 1857) and Nylanderia ( Hymenoptera : Formicidae ) ( Figs. 211–217 View FIGURES 210–217 ). The adults emerged two months later in the laboratory ( Figs. 224–226 View FIGURES 218–226 ). Adults are also found under stones ( Figs. 218–219 View FIGURES 218–226 ), and rotten wood with Crematogaster ants ( Figs. 220–223 View FIGURES 218–226 ).

Remarks. All similar specimens from Hainan we examined are the new species C. velutina , which bear uniform character of heavily tomentous body without posthumeral and lateral tomentous spots. The record of C. davidis from Hainan in Ma (2002a) was based on a C. velutina specimen based on the two voucher specimens preserved in the IZAS, and another one from the BMNH.
