Paithrips Nonaka & Jangvitaya, 1994b: 46 . Type species: P. c i rc u l ar i s Nonaka & Jangvitaya, 1994b, by original designation and monotypy.

Female. Wing fully developed. Head ( Fig. 1 B) wider than long, slightly constricted just behind compound eyes, slightly rounded at cheeks; ocellar setae I absent, setae II often very long, setae III situated at tangent of posterior margin of hind ocelli; four pairs of postocular setae present. Compound eyes slightly bulged, with five pigmented ommatidia slightly larger than normal ommatidia. Mouth-cone short and rounded at apex with 3-segmented maxillary palpi. Antennae ( Fig. 2 B) 8-segmented, segment I with two dorsal apical setae, III and IV with forked sensoria.

Pronotum ( Fig. 1 B) wider than long and not much longer than head, distinctly sculptured with narrowly spaced transverse anastomosing striae, sculpture with some small circles near medially; two pairs of posteroangular setae developed; two or three pairs of anteromarginal setae often very long; three pairs of posteromarginal setae present. Mesonotum ( Fig. 2 D) weakly sculptured or distinctly sculptured with transverse anastomosing striae on posterior half; median pair of setae situated near posterior margin. Metascutum ( Fig. 2 D) sculpture transversely reticulate or arched medially; campaniform sensilla absent; median pair of setae behind anterior margin ( Fig. 4 ). Prosternal ferna narrowly separated at middle. Mesosternum with sternopleural suture weak and incomplete, not reaching anterior margin; endofurca with spinula. Metasternal endofurca without spinula. Metaepimeron with two setae. Metaepisternum without seta. Metapreepisternum developed and with two setae. Fore wing first vein with median long gap in setal row and two or three distal setae, second vein with many almost equally spaced setae; clavus usually with four veinal and a discal setae; posteromarginal cilia wavy. Tarsi 2-segmented.

Abdominal tergites without ctenidia and posteromarginal craspeda; tergites II–VII with three setae (S3 to S5setae) arranged in a straight line along lateral margin (cf. Fig. 3 B); tergite VIII ( Fig. 4 B) without posteromarginal comb; tergite X without median slit; sternites without posteromarginal craspeda and discal setae; sternites II– VII with 3 pairs of posteromarginal setae; laterotergites without discal setae. Ovipositor developed.

Male. General structure and colour similar to female. Abdominla tergite IX with a pair of posteromarginal drepanae (cf. Fig. 3 C); sternites III–VIII each with some scattered small pore plates (cf. Fig. 3 D).
