Distinguishing features

Female fully winged. Body brown, fore wings light brown. Antennae 8-segmented; segment II with external margin prolonged and bearing a terminal seta-like sensorium; III–IV each with stout simple sense cone. Head small, prolonged in front of eyes; 3 pairs of ocellar setae present, pair III anterolateral to fore ocellus. Pronotum trapezoidal, with 2 pairs of posteroangular setae. Metanotum reticulate, sculpture forming arches around posterior midpoint; median setae smaller than lateral pair. Meso and metasternal furca with well-developed lateral flanges, without spinula. Fore wing pointed at apex; first vein with 2 setae on distal half, second vein with 4 setae. Tergites with antecostal ridge strong, complete lines of sculpture medially; posterior margins with entire but weakly lobed craspedum; ovipositor weak with faint teeth. Sternites with 3 pairs of marginal setae, posterior margins with craspedum of distinctive tubercles.
Male with wing lobe minute. Head without ocelli; metanotum transverse; tergites with strong lines of sculpture medially; sternites III–VII with small circular pore plate.

Related species

zur Strassen (1960) provided identification keys to over 50 species of Chirothrips, but Bhatti (1990) created six new genera for species previously placed in this genus. Chirothrips appears to be a genus of Holarctic species, whereas Arorathrips is from the New World. C. manicatus belongs to a group of mainly Old World species in which the head is not greatly prolonged in front of the eyes, the vertex bears few setae, and the external apex of antennal segment II bears an exactly terminal sensorium.
