Description. Male (holotype). General appearance very similar to that of nominotypical subspecies but with following characteristic features: coloration greenish with whitish-greyish tinge on head, light brown eyes and proximal portion of antennal flagellum, greyish brown rest of this flagellum and dorsolateral keels of pronotum (including stripes on lateral lobes along above-mentioned keels), light greyish brown stripe along tegminal M-MP vein (including this vein) and spot on basal tegminal area near anal edge, transparent wing membranes approximately as in S. (F.) irregulariterdentatum , greyish dorsum of hind tibia and areas on tarsi, as well as darkish abdominal tergites and dark small apical denticle on cercus ( Figs 107–110 View Figs 106–117 , 118–120 View Figs 118–125 , 126–128 View Figs 126–144 ); rostral tubercles, pronotum, legs and most part of wings practically indistinguishable from those of nominotypical subspecies in structure, but tegmina with stridulatory apparatus as in Figs 119–121 View Figs 118–125 (stridulatory vein about 5.5 mm in length and with almost 96 ventral teeth); abdominal apex with posteromedian process of last tergite gradually narrowing to rounded apex, and with other structures as in Figs 126–128 View Figs 126–144 .

Female. Coloration and structure of body almost as in male, but darkish stripes on pronotal lateral lobes along dorsolateral keels narrower, tegmina without developed stridulatory apparatus and completely transparent areas, abdominal apex with a pair of large triangular lamellar lobules and small rounded posteromedian lobule on last (tenth) tergite (latter small lobule probably mentioned by Emsley (1970) as “median process of the ninth tergite”) but without lobules or processes on other tergites ( Fig. 129 View Figs 126–144 ); genital plate and ovipositor as in Figs 130, 131 View Figs 126–144 .

Length in mm. Body: male 34, female 43–45; body with wings: male 92, female 98–101; pronotum: male 11, female 12–13; tegmina; male 75, female 78– 80; hind femora: male 39, female 39–41; ovipositor 7–7.5.

Comparison. The new subspecies differs from C. (P.) granti granti (from Guyana and possibly Surinam) in the posteromedian process of the male last tergite gradually narrowing to the apex (but not apically widened), and the posteromedian lobule of the female last tergite rounded in the dorsal view (vs: probably angular in this view; see data by Emsley (1970) for the Surinam female). In French Guiana and Brazil ( Emsley 1970), some other subspecies are possible. From C. (P.) tani , the new subspecies differs in the presence of distinct dark spots on the bases of the male tegminal dorsal fields, a distinctly wider base of the male last tergite posteromedian process and an almost truncate apex of the male genital plate (vs: this plate has a distinctly angular apical notch).
