Andrethrips Mound

Andrethrips Mound, 1974:110 . Type species: Andrethrips floydi Mound , by monotypy.

This remarkable genus from SE Asia is easily recognized by the presence of long barbed setae on elongate dorsal tubercles on the body, and each leg with a tarsal tooth and hamus equally developed. Of the two fungus-feeding species in the genus, floydi was described from Malaysia on two females, and Okajima (1998a) described insularis from Thailand based on three females and one male. Andrethrips is related to the genera with two pairs of wingretaining setae on tergite VIII, such as Solomonthrips , Phylladothrips and Propesolomonthrips . However, the sensorium on antennal segment II is placed near the base of that segment, as in members of the Plectrothrips genus-group.

Diagnosis: Body with many long and barbed setae arising from elongate tubercles; head with well-developed projection in front of eyes; cheeks notched behind eyes; stylets retracted into head capsule, V-shaped; antennae 8- segmented, campaniform sensorium situated near base on segment II, III with 2 sensoria, IV with 4; pronotum with 6 pairs of barbed setae, notopleural sutures reduced; basantra absent; mesopresternum eroded medially, divided into two lateral plates; sternopleural sutures absent; each leg with tarsal tooth and hamus equally developed in both sexes; fore wings narrow, without duplicated cilia; pelta broad; tergites II–VIII with 2 pairs of wing-retaining setae; tergite IX with S1 flattened and fringed, S2 and S3 slender; tube parallel-sided, slender, much longer than head, anal setae much shorter than tube; male sternite VIII without pore plate.
