(2010a : 206 ) (diag., desc. of female genitalia). Several additional works are available on its ecology. Type material examined. Thailand : 1 Ƌ, Chiang Mai : Mae Rim (Mae Raem), Muang Kaew , 9 Feb 1988 , Y. Hirose ( holotype , USNM ) ; 1 ♂ , Tak , Thoen , Bang Mae Wa , eggplant, 17º33' N 99º13' E , 28.i.1992 , F.D.

Recognized by its almost totally fuscous, small, circular body; shiny dorsal surface with rather sparsely distributed, silky, semi-erect setae; fuscous head with apically reddish clypeus; antennae almost wholly creamy yellow with segments III and IV usually reddish; coarsely and rather densely punctate pronotum with narrowly lamellate lateral margins; rounded, narrowly lamellate hemelytral exocorium; paramere distinctly twisted, with cone bearing a thin dorsal projection at middle and a dorsal reflexed flap at base of slender, apically recurved flagellum ( Figs. 28 , 34 ); and female copulatory tube short ( Fig. 34 ). See Yamada et al. (2010) for further diagnostic characters. Fifth instar nymph ( Fig. 17 ): recognized by its rounded, tortoise-shaped body; shiny chestnut-brown basic coloration (except for pale reddish or yellowish brown vertex, frons and lateral margins of wing pads); sparse, simple vestiture on dorsum; and almost totally yellow antennae and legs. Remarks. This species has been regarded as a potential candidate for biological control against tiny economically important arthropods, such as Thrips palmi Karny, 1925 (Thysanoptera: Thripidae) and Tetranychus kanzawai Kishida, 1927 (Acari: Tetranychidae) ( Uefune et al. 2010 , Nagai et al. 2013 ). In Myanmar , both the adults and late immature forms were observed to co-exist with a typhlocybine leafhopper (Cicadellidae: Typhlocybinae) and a tingid, Haedus sp. ( Tingidae : Tinginae ), on Urena lobata L. (Malvaceae) ( Figs. 14, 18−19 ), where the leaves were heavily damaged by aggregations of the leafhopper and tingid ( Fig. 14 ); Wollastoniella rotunda is assumed to prey on both or one of them.
