Type material. Holotype ♀ (CNC): “ Bolivia, La Paz, Chulumani , APA-APA S16°22' W67°30' 1–4.VII.1997, 1800m, L. Masner col. YPT B9–11”

Description of holotype, ♀. Body length: 2.6 mm; fore wing length: 2.2 mm.

Color. Head black except for gena fading apically to white, mandibles dark brown and palpi light yellow to whitish yellow. Mesosoma black. Wings hyaline, stigma and venation brown. Fore and middle legs with coxa dark brown, trochanter and trochantellus yellow, femur dark brown to black with apex yellow, tibia and spurs light yellow, tarsi dark brown. Hind legs with coxae black fading apically to dark brown, remainder of hind legs with the same aspect of fore and middle legs except for femur dark brown. Metasoma dark brown except for anterior T1 black and ovipositor yellow.

Head. Length of head in dorsal view 0.6× its width. Temples weakly narrowing posteriorly. Antennae 0.8× as long as the body; scape 2.5× longer than wide; flagellomeres 10–17 with a distinct expansion apical-ventrally. Eye height 2.0× the malar space. Mostly punctate; striate at face and around eyes dorsally; vertex mostly rugose. Malar suture present.

Mesosoma. Mesoscutum finely areolate rugulose anteriorly to punctate posteriorly. Notauli absent. Propleuron smooth. Pronotum rugose. Scutellar sulcus with 8 divisions, scutellum polished with shallow punctation. Mesopleuron smooth with sternaulus costate. Metanotum and mesoscutellar trough rugose. Metapleuron rugose striate, but smooth and polished anteriorly. Propodeum strongly rugose, with complete transverse carina; without defined areola but with a sub-longitudinal carina on apical half (in high magnification it is possible to see an indication of a second carina just at the right side, extremely reduced and forming a very acute angle, nearly parallel, with the more distinct left carina).

Wings. Fore wing vein r 0.1× the stigma height; vein R1 0.17× the stigma length; stigma.3.5× longer than high

Legs. Hind leg with inner tibial spur 0.23× longer than tibia; hind tibia about 4.2× longer than its maximum width. All legs smooth except for hind coxae dorsally rugose.

Metasoma. Entirely smooth except for T1 weakly rugulose mid-basally.

Male. Unknown.

Diagnosis. Adelius boliviensis sp. n. resembles Adelius excelsus sp. n. in having a rugose hind coxa, black color, and by the presence of the fore wing vein r. It can be distinguished by the presence of at least one median carina on posterior aspect of propodeum, as contrasting with no carina in A. excelsus . The wings are hyaline with a dark brown stigma in A. boliviensis , while the wing is infuscate with yellow stigma in A. excelsus . The color of the legs is also a useful diagnostic character with at least all trochanters and trochantelli and tips of all femora honey yellow in A. boliviensis , as compared with the legs being completely black in A. excelsus .

Biology. Unknown.

Distribution. Only known from the type locality in Bolivia.

Etymology. This species is named after the country where the holotype was collected.
