(Figs. 14−17, 20−21, 28, 34)
Wollastoniella rotunda Yasunaga & Miyamoto, 1993: 227 (n. sp.); Yamada et al. (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. Benett & R.M. Baranowsky (AMNH _PBI 00380434) (paratype, TYCN); 3 ♂♂ 3 ♀♀, same data (paratypes, TYCN); 1 ♀, Chiang Mai, Mae Taeng, Khi Lek, eggplant, 19º04'N, 98º54'E, 16.ii.1988, Y. Hirose, (00380435) (paratype, TYCN); 2 ♂♂ 2 ♀♀, Mae Raem, Muang Kaew, eggplant, 9.ii.1988, Y. Hirose (paratypes, TYCN).
Diagnosis. 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.
