Shape of head: subglobose. Central keel of frons: absent. Setation of upper frons: with sparse, long setae. IOS/EH: IOS distinctly less than EH. Sculpture of ventrolateral frons: transversely rugulose to granulate. Sculpture of frons below median ocellus: granulate. Sculpture of posterior vertex: granulate. Hyperoccipital carina: absent. Occipital carina medially: interrupted. 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. Form of male antennal flagellomeres: filiform, A11 approximately 2.0 × longer than wide. Length of A5 tyloid in male: greater than 0.5 × length of A5.

Color of mesosoma in female: orange throughout. Color of mesosoma in male: orange throughout. Sculpture of dorsal pronotal area: rugose. Sculpture of lateral pronotal area: smooth throughout. Sculpture of netrion: smooth. Notaulus: percurrent or nearly so. Sculpture of mesoscutum: granulate. Shape of mesoscutellum: semiellipsoidal. Foveolae of scutoscutellar sulcus between notauli: smaller than those along margin of axilla. Sculpture of mesoscutellum: granulate. Shape of metascutellum: posterior margin rounded, approximately 2.5 × wider than long. Sculpture of metascutellum in female: rugose. Sculpture of metascutellum in male: rugose. Dorsal propodeum in female: shallowly excavate medially, with lateral propodeal carinae widely separated. Sculpture of dorsal propodeum in female: rugose. Sculpture of dorsal propodeum in male: rugose. Median keels on propodeum in female: absent. Mesopleural carina: present. Sculpture of mesepisternum below mesopleural depression: smooth. Sculpture of ventral metapleural area: rugose. Color of legs: orange throughout; pale yellow throughout. Sculpture of hind coxa: smooth.

Color of fore wing: hyaline. Rs+M: nebulose, weakly pigmented; spectral. Setae on R: long, erect, surpassing the margin of the wing. Length of R: distinctly shorter than r-rs. Length of R1: approximately as long as 2.0 × length of r-rs.

Color of metasoma in female: orange throughout; yellow with variable pale brown patches. Color of metasoma in male: orange throughout; variably orange to pale brown. Horn on T1 in female: present as a small bulge. Sculpture of T1 horn dorsally: with V-shaped striae. Sculpture of posterior margin of T1 in female: longitudinally striate throughout. Sculpture of T1 in male: longitudinally striate. Development of longitudinal striae on T2 in female: reaching posterior margin of T2. Sculpture of T3: smooth medially, longitudinally striate laterally; longitudinally striate throughout. Shape of T6 in female: short, slightly longer than wide. Sculpture of S3: densely punctate medially, longitudinally striate laterally.

Diagnosis.

This species is most similar to Calliscelio carinigena and Calliscelio crater in color, size and habitus but it can be distinguished by the absence of the hyperoccipital carina (hyperoccipital carina are absent in Calliscelio carinigena and Calliscelio crater ).

Etymology.

The specific epithet is Greek for wedge and should be treated as a noun in apposition. It refers to the “wedge-like” horn on T1 in the female.
