Description.

Body length of female: 1.35-2.05 mm (n=20). Color of head: brown throughout; yellow throughout; yellow, becoming darker at vertex. Color of antennal clava (A7-A12): A7 orange, remainder dark brown to black. Shape of head: subglo bose. Central keel of frons: present. Setation of upper frons: with sparse, long setae. IOS/EH: IOS distinctly less than EH. Sculpture of ventrolateral frons: smooth with sparse punctures. Sculpture of frons below median ocellus: largely smooth with sparse fine punctures. Sculpture of posterior vertex: largely smooth with sparse fine punctures. 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: smooth. Ocular setae: absent. A4 in female: distinctly shorter than A3. A5 in female: shorter than A3, slightly longer than wide. Shape of female A6: as long as wide.

Color of mesosoma in female: orange throughout; yellow throughout; dark 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: coriaceous. 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 4.0 × wider than long. Sculpture of metascutellum in female: smooth with a longitudinal, median carina. 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: pale yellow throughout. Sculpture of hind coxa: smooth.

Color of fore wing: hyaline. Rs+M: nebulose, strongly pigmented. Setae on R: long, erect, surpassing the margin of the wing. Length of R: approximately as long as r-rs. Length of R1: greater than 3.0 × length of r-rs.

Color of metasoma in female: orange to pale brown; orange throughout; yellow throughout. Horn on T1 in female: large and distinct. Sculpture of T1 horn dorsally: rugulose; transversely striate. Sculpture of posterior margin of T1 in female: longitudinally striate throughout. Development of longitudinal striae on T2 in female: present on anterior margin of T2 medially, reaching posterior margin of T2 laterally. Sculpture of T3: smooth with longitudinal submedian striae. Shape of T6 in female: short, approximately 1.5 × longer than wide. Sculpture of S3: smooth.

Diagnosis.

This species is most similar to Calliscelio levis and Calliscelio migma . It may be separated from Calliscelio levis by the well-developed T1 horn in the female, from Calliscelio migma by having A5 in female slightly longer than wide, and A6 quadrate, whereas both antennomeres are distinctly longer than wide in Calliscelio migma .

Etymology.

The epithet is used as a genitive noun derived from the name of the collector of the holotype.
