Description.

Body length of female: 2.23-2.97 mm (n=20). Body length of male: 1.86-1.91 mm (n=3). Color of head: black throughout; orange throughout; variably brown to black; variably orange to dark brown. Color of antennal clava (A7-A12): black. Shape of head: subglobose. Central keel of frons: present. Setation of upper frons: with dense, short setae. IOS/EH: IOS distinctly less than EH. Sculpture of ventrolateral frons: granulate. Sculpture of frons below median ocellus: coriaceous; smooth to coriaceous. 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: smooth. Ocular setae: absent. A4 in female: distinctly longer than A3. A5 in female: longer than A3, distinctly longer than wide. Shape of female A6: length distinctly greater than width. Form of male antennal flagellomeres: filiform, A11 approximately 4.5 × longer than wide. Length of A5 tyloid in male: approximately 0.3 × length of A5.

Color of mesosoma in female: orange throughout; black throughout; variably orange to pale brown. Color of mesosoma in male: brown throughout; black 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: coriaceous; granulate. 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. Sculpture of metascutellum in male: rugose. Dorsal propodeum in female: deeply excavate medially, with lateral propodeal carinae widely separated, running subparallel to accommodate T1 horn. Sculpture of dorsal propodeum in female: rugose. Sculpture of dorsal propodeum in male: rugose with one or two longitudinal keels lateral to median keel. Median keels on propodeum in female: absent. Mesopleural carina: present. Sculpture of mesepisternum below mesopleural depression: smooth. Sculpture of ventral metapleural area: smooth. Color of legs: orange yellow; hind femur brown, otherwise yellow. 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: distinctly longer than r-rs. Length of R1: greater than 3.0 × length of r-rs.

Color of metasoma in female: dark brown; orange throughout; variably orange to black. Color of metasoma in male: brown throughout; variably yellow to pale brown; black throughout. Horn on T1 in female: large and distinct. Sculpture of T1 horn dorsally: transversely striate; smooth to somewhat transversely striate. 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; present on anterior margin of T2 medially, reaching posterior margin of T2 laterally. Sculpture of T3: smooth; smooth with longitudinal submedian striae. Shape of T6 in female: distinctly elongate, approximately 3.5 × longer than wide. Sculpture of S3: largely smooth with sparse and fine punctures.

Diagnosis.

The females of this species are most similar to Calliscelio laticinctus and Calliscelio prolixus in color, size and habitus. It can be separated from Calliscelio laticinctus by A4 distinctly longer than A3 and A5 longer than A3, from Calliscelio prolixus by the presence of T1 horn and the elongate T6.

Etymology.

The epithet is an adjective, the Latin word for longer, in reference to A5 longer than A3.
