DIAGNOSIS. MALE. Head black with yellowish spot inside eye. FEMALE. Head black with yellowish spot below eye.

DESCRIPTION. MALE. Body length 6.1 mm. Median triangular area of clypeus raised. Scape below with single carina. Gular margins distinctly carinate and elevated to a distinct tooth. Mesosoma ferruginous, pronotum, mesonotum and scutellum with sparse, pale setae. Humeral angles of pronotum angulate, not prominent; lateral margins of pronotum straight. Parapsidal furrows of mesonotum absent. Posterolateral angles of scutellum produced into a short, subspinose process. Posterolateral angles of propodeal dorsum not produced at all, evenly rounded into posterior face, latter and propodeal dorsum broad, deeply reticulate. Wings fuscous. T2 disc sparsely punctured, glabrous, laterally and anteriorly densely punctured. T3 with small, distinct punctures, and with band of dense, appressed, pale setae, somewhat constricted medially. T4-6 with small, dense, distinct punctures, except impunctate, glabrous, broad posterior margin of each. T7 with large, dense, confluent punctures throughout. S8 (hypopygium) with small, dense, confluent punctures throughout.

FEMALE. Body length 4.8-6.4 mm. Head black with yellowish spot below eye.

Mesosoma and legs ferruginous, metasoma black. Median triangular area of clypeus elevated. Antennal tubercles strongly carinate above, carinae connected by a transverse carina. Humeral pronotal angles angulate, not prominent. Lateral margins of mesonotum broadly angulate anteriorly, mesosoma widest at this angulation, with sides gradually converging posteriorly. Mesosoma dorsally with dense, confluent punctures and sparse, erect and recumbent, ferruginous setae. Scutellar scale absent. Lateral margins of posterior propodeal face slightly denticulate anteriorly. T2 without setal fovea on anterolateral angles. Anterior surface of T1 with sparse, erect pale and recumbent fuscous setae; anterior half of dorsum of T1 with dense, confluent punctures, and sparse, erect, fuscous setae, posterior half glabrous, impunctate. Anterior 2/3 of T2 with moderate, dense, confluent punctures, becoming smaller and closer in posterior third, distal margin of T2 glabrous, impunctate. T2 with sparse, erect and recumbent, blackish setae, except lateral fourths with sparse, pale setae. T3 with complete, uninterrupted band of pale setae, with small, dense, shallow punctures anteriorly. T4-5 with small, shallow, close, confluent punctures, except for the broad distal margin of each, glabrous and impunctate, with sparse, erect and recumbent, fuscous setae. T6 densely punctate throughout, with sparse, pale setae.

DISTRIBUTION. Indonesia (Sulawesi).

ETYMOLOGY. I am pleased to name this new species in honour of Seiki Yamane, an expert in wasp and ant taxonomy, who collected the holotype of this species. Treat as a noun in apposition.

REMARKS. The male and female of this new species can be distinguished from all other congeners by the yellowish spot inside the eye of the male and below the eye of the female. The collection of male and female at the same site in Sulawesi allows me to treat them as opposite sexes of the same species. Furthermore, the genus Yamanetilla is represented on Sulawesi by one species of male and one species of female. There is no direct evidence for this relationship.
