Diagnosis. The male genitalic characters referred to in the generic diagnosis of Bruneiplusia differentiate this species from all other Diallactiini .

Other male characters. Body length about 2.0 mm. Head. Postgenal setae not clustered. Eye bridge covering all the vertex. Scape and pedicel concolorous with flagellum, scape with 2 setae, pedicel unsetose. Maximally 8 flagellomeres retained. Neck of fourth flagellomere (Fig. B) 1.5 times longer than node; node with short setae basally, in between a few short hair-like translucent sensilla, a crenulate whorl with long sensory hairs with hooded alveoli medially, more such sensory hairs scattered distally, especially ventrally, numerous short hair-like translucent sensilla distally, microtrichia only basally. Clypeus unsetose. Palpus shorter than head height, 4 segments, on all segments hair-shaped translucent sensilla, fourth segment longest. Thorax. Scutellum brown; scutum mostly brown; anepisternum light brown. Scutal and scutellar setae sparse. Wing length / width 2.8 (Fig. C). Membrane completely covered with setae. Costal break distinct; btv setose; both M1+2 and M4 absent; CuA extending to wing margin. Legs. Coxae slightly darker than femora and tibiae, tarsi slightly brighter. Basitarsi without spine. Claws slightly bent, untoothed. Empodia vestigial. Genitalia (Fig. A). Ninth tergite long, subtrapezoid, setose. Gonocoxae: ventroposterior edge slightly convex, membranous medially, a membranous, microtrichose outgrowth posteriorly; medial bridges with sclerotized edges; apodemes merged anteriorly to form a short bridge with long, narrow processes. Ejaculatory apodeme as long as gonocoxae.

Etymology. The species is named after David Kaspřák, PhD student at the University of Ostrava, who is one of the collectors of the specimens studied here from Brunei.

Type material. Holotype. Male, Brunei, Ulu Temburong National Park, Kuala Belalong Field Studies Centre, 30 Jan.–16 Feb. 2015, lowland mixed dipterocarp forest, Malaise trap (#4), D. Kaspřák & M. Mantič (in UBDC).
