Sculpture of frons below median ocellus: densely punctate. Sculpture of posterior vertex: densely punctate. Hyperoccipital carina: absent. Occipital carina medially: complete, strongly crenulate throughout. Length of OOL: less than 0.5 × ocellar diameter. Sculpture of postgena behind outer orbit: granulate with sparse punctures. Ocular setae: dense, long. A4 in female: distinctly shorter than A3. A5 in female: shorter than A3, as long as wide. Shape of female A6: distinctly wide than long. Form of male antennal flagellomeres: filiform, A11 approximately 2.5 × longer than wide. Length of A5 tyloid in male: greater than 0.5 × length of A5.

Color of mesosoma in female: black throughout. Color of mesosoma in male: black throughout. Sculpture of dorsal pronotal area: areolate. Sculpture of lateral pronotal area: smooth throughout. Sculpture of netrion: striate. Notaulus: percurrent or nearly so. Sculpture of mesoscutum: smooth with sparse punctures; coriaceous anteriorly, smooth with sparse fine punctures posteriorly. Shape of mesoscutellum: semiellipsoidal. Foveolae of scutoscutellar sulcus between notauli: as large as those along margin of axilla. Sculpture of mesoscutellum: smooth with sparse fine punctures. Shape of metascutellum: posterior margin straight, approximately 2.5 × wider than long. Sculpture of metascutellum in female: rugose; rugose anteriorly, smooth posteriorly. 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: largely smooth with a row of foveae along mesopleural carina. Sculpture of ventral metapleural area: largely smooth, rugose ventrally. Color of legs: orange throughout; pale yellow throughout. Sculpture of hind coxa: smooth.

Color of fore wing: subhyaline. Rs+M: nebulose, weakly pigmented. 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; reddish brown to black. Color of metasoma in male: variably orange to pale brown; brown throughout; reddish brown. Horn on T1 in female: present as a small bulge. Sculpture of T1 horn dorsally: smooth. 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: smooth. Shape of T6 in female: short, slightly longer than wide. Sculpture of S3: largely smooth with sparse and fine punctures.

Diagnosis.

This species (especially small specimens) is most similar to Calliscelio bisulcatus but can be distinguished by the long setae on upper frons and pigmented Rs+M.

Etymology.

The specific epithet refers to the punctate frons and should be treated as a noun in apposition.
