Description
Body length of female: 2.97 mm (n=1). Color of head: orange throughout. Color of antennal clava (A7–A12): dark brown to black. Shape of head: subglobose. Central keel of frons: absent. Setation of upper frons: with sparse, short setae. IOS/EH: IOS slightly greater than EH. Sculpture of ventrolateral frons: smooth with sparse punctures. Sculpture of frons below median ocellus: granulate to finely punctate. Sculpture of posterior vertex: granulate. Hyperoccipital carina: absent. Occipital carina medially: complete, weakly crenulate throughout. Length of OOL: less than 0.5× ocellar diameter. Sculpture of postgena behind outer orbit: granulate. Ocular setae: absent. A4 in female: distinctly shorter than A3. A5 in female: shorter than A3, as long as wide. Shape of female A6: distinctly wider than long.
Color of mesosoma in female: orange throughout. Sculpture of dorsal pronotal area: rugose. Sculpture of lateral pronotal area: rugulose throughout. Sculpture of netrion: rugose. Notaulus: percurrent or nearly so. Sculpture of mesoscutum: granulate. Shape of mesoscutellum: semiellipsoidal. Foveolae of scutoscutellar sulcus between notauli: absent. Sculpture of mesoscutellum: granulate. Shape of metascutellum: posterior somewhat rounded, approximately 2.5× wider than long. Sculpture of metascutellum in female: rugose. Dorsal propodeum in female: shallowly excavate medially, with lateral propodeal carinae widely separated. Sculpture of dorsal propodeum in female: rugose. Median keels on propodeum in female: absent. Mesopleural carina: absent. Sculpture of mesepisternum below mesopleural depression: smooth. Sculpture of ventral metapleural area: smooth. Color of legs: orange throughout. Sculpture of hind coxa: smooth.
Color of fore wing: hyaline. Rs+M: spectral. Setae on R: short, decumbent, hardly exceeding the margin of the wing. Length of R: distinctly shorter than r-rs. Length of R1: approximately as long as r-rs.
Color of metasoma in female: orange throughout. Horn on T1 in female: present as a small bulge. Sculpture of T1 horn dorsally: granulate medially, with V-shaped keels laterally. Sculpture of posterior margin of T1 in female: longitudinally striate throughout. Development of longitudinal striae on T2 in female: reaching posterior margin of T2. Sculpture of T3: longitudinally striate throughout. Shape of T6 in female: short, wider than long. Sculpture of S3: longitudinally striate.
Diagnosis
This species is most similar to the orange females of Calliscelio rubriclavus but can be distinguished based on the smooth sculpture of the mesepisternum below the mesopleural depression and the medially granulate T1 horn , with V-shaped keels laterally.
Etymology
The specific epithet refers to the locality on the label of the holotype and should be treated as a noun in apposition.
