Gorochov, L. Anisyutkin ( ZIN). Parsatypes: 3 females, same data as for holotype but collected 18–22.IX.2003 by A. Gorochov and M. Berezin ( ZIN); 1 male, same country, northern part of Elefan Mts, Kiri-Rom National Park in 150 km NNE of Sihanoukville Town, 600–800 m, secondary forest, on branch of bush at night, 7–10.X.2003, A. Gorochov, M. Berezin ( ZIN); 2 females, same country and park but in 130 km NNE of Sihanoukville Town, 300–500 m, 27.VIII– 6.IX.2003, A. Gorochov, M. Berezin ( ZIN); 1 male, same country, central part of Elefan Mts, Styeng-Chkhral Vill. in 100 km NE of Sihanoukville Town, 300–500 m, 27.VIII–6.IX.2003, A. Gorochov, L. Anisyutkin ( ZIN).

Description. Male (holotype). Size and structure of body very similar to those of C. ph. phaeocephala Gorochov, 2003 ( Thailand: Nakhon Ratchasima Prov.). However, colouration somewhat different from that of nominotypical subspecies: most part of head (including clypeus, labrum and mandibles) reddish brown with a few dark brown spots on dorsum, on upper part of genae, on area between antennae (including dark borders of antennal cavities), and along lateral parts of clypeal suture, with light brown to yellowish ocelli, a pair of rather large spots between upper parts of eyes, a few smaller marks on hind part of dorsum and on lower part of clypeus, and areas on subgenae; antennae with reddish brown proximal part having a few lighter spots on scape, and with light brown middle and distal parts; maxillae and labium yellowish with reddish tinge, with brown most part of maxillary palpi, and with light brown distal half of labial palpi; pronotum almost dark brown but with rather wide yellowish transverse band running along posterior edge of lateral lobes and of disc, with brown borders behind and under this band, with brown to light brown stripe along anterior edge of disc and a pair of large spots behind this stripe; rest of body similar to that of C. ph. phaeocephala in colouration, yellowish with reddish spines of fore and middle tibiae, with reddish brown tinge on femoral apices and on tibial distal parts, with light reddish brown tarsi, with brown distal parts of spines on hind legs and of hooks on 9th abdominal tergite, with distinctly darkened (brownish grey) crossveins in tegmina and hind wings, as well as with transparent membranes of hind wings (however, these membranes with rather wide darkenings around majority of crossveins, but these darkenings narrower than in C. ph. phaeocephala ; Fig. 55 ).

Variations. All other males slightly or distinctly lighter: head sometimes without dark brown marks or light brown with reddish brown lower half of face and a few brown spots on its upper half; pronotum also varied from brown with lighter marks to light brown with a few darkish lines only, but sometimes most part of pronotum almost completely dark brown and distinctly darker than general colouration of head.

Female. General appearance as in male but with abdominal apex very similar to that of female of C. erythrocephala (see Gorochov, 2003): genital plate almost oval, clearly narrowing to apex, with slightly notched apical part (this part sometimes looking as almost truncate) and medium-sized copulatory opening at base (this opening slightly larger than that shown in Fig. 51 ); ovipositor long, rather narrow and barely arcuate (barely curved upwards) in profile, and with very narrowly rounded apex.

Measurements (in mm). Length of body: male 22–31, female 21–26; body with wings: male 35–44, female 36–42; pronotum: male 6.3–7; female 6.8–7.5; tegmen: male 26–32, female 28–31; hind femur: male 16–18, female 17–19; ovipositor 21–23.5.

Comparison. The new suibspecies differs from C. ph. phaeocephala mainly in a lighter colouration of the head and pronotum (in the nominotypical subspecies, most part of head including scapes and of pronotum are almost completely black, not brown or light brown with darker marks), and in somewhat narrower darkish areas around crossveins in the hind wings. From the other similar species living in the nearest countries, C. ph. cambodiensis may be distinguished by the absence of blackish areas on the genae, mandibles and labrum, by the presence of a light area on the hind pronotal part, and by a normal distal tegminal part (in C. rubrocellata Gorochov, 2003 from Thailand, this tegminal part is distinctly narrowing to the apex; for comparison see Figs 54 and 55 ).

Etymology. This subspecies is named after the country where it was collected.
