Diagnosis. This species differs from C. greeni by the rectangular prominent spots on the crown, brown basal triangles of the exposed mesonotum, the male pygofer with serrated ventral process that is not twisted and the aedeagus lacking lateral lamellate processes on the shaft.

Description. Ochraceous. Crown with one small brown spot near fore margin and another large black rectangular spot on either side of median line. Face pale brown with a median spot on clypellus brown, median area on frontoclypeus paler. Eyes dark gray. Pronotum anterior submargin irregularly marked with yellow. Exposed mesonotum yellow with basal triangles brown. Forewing uniformly ochraceous with paler venation. Thoracic and abdominal tergites and sternites pale ochraceous. Legs pale ochraceous, bases of setae on meta tibia brown.

Head slightly narrower than pronotum or as wide as pronotum. Crown about 0.6–0.8× as long as interocular distance. Pronotum 2.1× as wide as long medially, about 1.5× as long as median length of crown and about as long as exposed mesonotum. Female sternite VII, slightly narrowed posteriorly, posterior margin with inverted V-shaped excavation medially.

Male genitalia. Pygofer 1.4× as long as wide basally in lateral view, posteriorly conically rounded; ventral process directed posteriorly, blade-like, straight, with dorsal margin serrate, strongly narrowed and pointed, far exceeding pygofer posterior margin. Subgenital plate about 2.75× as long as basal width. Style apophysis of uniform width, lacking subapical lobe, apex rounded. Aedeagus as in generic description, shaft without lateral expansions.

Measurements. Male 4.4–4.9 mm long, 1.0– 1.1 mm wide across eyes and 1.1–1.2 mm wide across posterolateral angles of pronotum. Female 5.1–5.4 mm long, 1.1–1.2 mm wide across eyes and 1.2 mm wide across posterolateral angles of pronotum.

Etymology. The specific epithet is the Latin adjective serratus, -a, -um, (= saw-shaped, serrated) referring to the serrated dorsal margin of the male pygofer process.

Remarks. This species externally resembles P. maculiceps in coloration, but has entirely different male genitalia. The males from Mudigere and the female from Burliar do not have the small brown spots near fore margin of the crown and these and the specimens from Thekkady have a brown spot at the apices of the claval veins and clavus.
