Description.

Body length of female: 1.74-2.35 mm (n=20). Body length of male: 1.86-2.36 mm (n=20). Color of head: black throughout; variably orange to dark brown. 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, long setae. IOS/EH: IOS distinctly less than EH. Sculpture of ventrolateral frons: smooth to granulate. Sculpture of frons below median ocellus: granulate. Sculpture of posterior vertex: granulate above hyperoccipital carina, smooth to rugulose below. Hyperoccipital carina: present. Occipital carina medially: interrupted. Length of OOL: less than 0.5 × ocellar diameter. Sculpture of postgena behind outer orbit: with large foveae. Ocular setae: absent. A4 in female: distinctly shorter than A3. A5 in female: shorter than A3, as long as wide. Shape of female A6: subquadrate. 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; variably orange to pale brown. Sculpture of dorsal pronotal area: rugose. Sculpture of lateral pronotal area: smooth anteriorly, granulate posteriorly. 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 mes oscutellum: granulate. Shape of metascutellum: posterior margin straight, 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: absent. Sculpture of mesepisternum below mesopleural depression: smooth. Sculpture of ventral metapleural area: largely smooth, rugose ventrally. Color of legs: orange throughout. Sculpture of hind coxa: smooth.

Color of fore wing: hyaline. Rs+M: 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; T1 horn and T6 pale brown, otherwise orange throughout. Color of metasoma in male: variably orange to pale brown. Horn on T1 in female: present as a small bulge. Sculpture of T1 horn dorsally: rugose medially, with V-shaped keels laterally. 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 the middle of T2 medially. Sculpture of T3: coriaceous; granulate; smooth medially, coriaceous laterally; longitudinally striate throughout. Shape of T6 in female: short, slightly longer than wide. Sculpture of S3: smooth to coriaceous.

Diagnosis.

This species is similar to Calliscelio carinigena and Calliscelio sfina in color, size and habitus, but it can be easily recognized by the large foveae on the postgena (postgena of Calliscelio sfina granulate, whereas Calliscelio carinigena with a carina along outer orbit).

Etymology.

The specific epithet refers to the foveae on the postgena and should be treated as a noun in apposition.
