Generic diagnosis

Female macropterous. Head wider than long, ocellar region without sculpture; maxillary palps 3-segmented; eyes large with 5 weakly pigmented facets; ocellar setae pair I present, pair III posterior to tangent joining posterior margins of hind ocelli; five pairs of small postocular setae. Antennae 8-segmented, segment I without paired dorso-apical setae; III and IV with sense cones forked, IV with additional simple sense cone dorso-laterally; III–VI with rows of microtrichia on both surfaces. Pronotum trapezoidal, almost without sculpture lines and setae minute; four pairs of posteromarginal setae, two pairs of long posteroangulars. Mesonotum anterior campaniform sensilla present; median setal pair minute and close to posterior margin. Metanotum reticulate; median pair of setae at anterior margin; campaniform sensilla present near posterior margin. Fore wing first vein with setal row almost complete, distal four setae widely spaced; second vein setal row complete; clavus with five marginal and one discal setae; posterior cilia wavy. Prosternal ferna robust, complete medially; basantra rugose membranous, without setae; prospinasternum broad and transverse; endofurca with prominent spinula; mesosternal sternopleural sutures complete. Metasternal furca without spinula. Tarsi 2-segmented; fore femora inner margin angulate, with pointed tubercle near base; fore tibiae each with two short, broadly rounded, bulbous modified setae. Tergites V–VIII with narrow craspeda; VIII with paired ctenidia anterolateral to spiracles, VI–VII with ctenidia terminating at median lateral marginal seta, IX with two pairs of campaniform sensilla. Sternites without discal setae, III–VII with 3 pairs of marginal setae, II with two pairs; sternite VI with pair of small circular pore plates.
Male sternites III–VII each with a large transverse pore plate, tergite IX without drepanae.

Biological data

Collected from the flowers of Dalbergia yunnanensis [Fabaceae] (Zhang et al., 2010).

Distribution data

Known only from the type series collected in Sichuan, China.

Nomenclatural data

Yaobinthrips Zhang, Mound & Xie, 2010: 65. Type species Yaobinthrips yangtzei Zhang, Mound & Xie, 2010, by monotypy.

Only one species is known in this genus (ThripsWiki, 2020), and this was collected in southern China:

yangtzei Zhang, Mound & Xie, 2010: 68.

Relationship data

Thripidae sub-family Thripinae: this is a diverse group involving more than 230 genera. Yaobinthrips is one of nine genera in the Frankliniella-group (Mound, 2002), and is probably related to Parabaliothrips. The single species is unique in the group in the presence of tergal craspeda, and for the presence on each fore tibia of a curious stout, bulbous seta, but in a phylogenetic analysis based on morphology (Wang et al., 2019) it grouped in the same clade as Parabaliothrips and Firmothrips.
