Beesoniella Lallemand, 1933:2 .

Type-species by monotypy: B. sylvestris Lallemand, 1933 .

Distribution. Mountainous regions of India to southeast Asia. Only the type-species of the genus is widespread. It was described from two specimens collected from “the foliage of sandal[wood],” Santalum album L. ( Lallemand 1933) in India. One male and three females of the same species have also been found in Laos and Vietnam (BPBM).

Diagnosis. Form slender but hump-backed ( Fig. 1 B); head narrower than pronotum, face receding, almost concealed beneath pronotum; tylus absent ( Fig. 6 C); eyes transverse; ocelli set further apart than distance to eyes; antennal ledges high, thin and nearly flat before antennal pits, with 3 preantennal bristles in a vertical row on rim on pit; antennal postpedicel a truncate cone with single coeloconic sensillum set in deep pit and placoid sensillum surrounded by narrow, septate groove (Fig. 21D). Lateral margins of pronotum much shorter than eyes; pronotum arched, fore border steeply declivous, densely punctate. Tegmina flat, densely punctate, venation obscure. Hind wings each with 6–8 hooks on costal margin, 3 mounted on triangular process; first cell as large as in Cercopidae . Fore and hind femora of similar length; hind tibiae each armed with 2 large spines on basal half; hind basitarsi as long as other tarsomeres together; pectens of hind tibiae with 8 black-tipped spines, those of basitarsomere with 5 such spines, those of second tarsomere with 7 such spines. Male with subgenital plates obscure, forming low sinuation on posterior edge of pygofer; 2 pairs of pygofer processes ( Fig. 12 A, E): a digittate median pair and a dorsoventrally flattened lateral pair with 1 or 2 acute angles posteriorly ( Fig. 12–14 B). Theca very broad, flattened ( Fig. 12 C–D), apex broadly notched, endotheca absent, 2 gonopores for gonoducts separating at base of theca ( Fig. 12 D). Length: 5–7 mm.

Included taxa. Three species, two of which are described below.
