Description.

Body length of female: 2.53-3.38 mm (n=10). Body length of male: 2.11-2.75 mm (n=5). Color of head: black throughout. Color of antennal clava (A7-A12): dark brown to black; A12 pale yellow, remainder 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 with sparse punctures. Sculpture of frons below median ocellus: smooth. Sculpture of posterior vertex: smooth. Hyperoccipital carina: absent. Occipital carina medially: interrupted. Length of OOL: greater than 0.5 × ocellar diameter. Sculpture of postgena behind outer orbit: smooth. Ocular setae: absent. A4 in female: as long as A3. A5 in female: shorter than A3, distinctly longer than wide. Shape of female A6: distinctly longer than wide. Form of male antennal flagellomeres: filiform, A11 approximately 3.0 × longer than wide. Length of A5 tyloid in male: approximately 0.3 × length of A5.

Color of mesosoma in female: orange throughout; variably yellow to pale brown. Color of mesosoma in male: orange throughout. Sculpture of dorsal pronotal area: rugose. Sculpture of lateral pronotal area: smooth anteriorly, granulate posteriorly. Sculpture of netrion: rugulose. Notaulus: percurrent or nearly so. Sculpture of mesoscutum: smooth with sparse punctures; coriaceous; densely punctate. Shape of mesoscutellum: semiellipsoidal. Foveolae of scutoscutellar sulcus between notauli: smaller than those along margin of axilla. Sculpture of mesoscutellum: smooth with sparse fine punctures. Shape of metascutellum: posterior margin somewhat rounded, approximately 4.0 × wider than long. Sculpture of metascutellum in female: finely crenulate. Sculpture of metascutellum in male: finely crenulate. 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 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: coxae to femur white, remainder of the legs pale yellow; pale yellow 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: approximately as long as r-rs. Length of R1: approximately as long as 2.0 × length of r-rs.

Color of metasoma in female: orange throughout; variably orange to pale brown. Color of metasoma in male: orange throughout; variably orange to pale brown. Horn on T1 in female: large and distinct. Sculpture of T1 horn dorsally: densely and concentrically striate anteriorly, smooth posteriorly. 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 with longitudinal submedian striae. Shape of T6 in female: distinctly elongate, approximately 3.0 × longer than wide. Sculpture of S3: largely smooth with sparse and fine punctures.

Diagnosis.

This species is most similar to Calliscelio remigio but can be distinguished by its subglobose head and densely and concentrically striate T1 horn on anterior portion in female. In males, it can be separated from Calliscelio remigio by the subglobose head and the largely smooth S3.

Etymology.

The specific epithet is a reference to the high degree of similarity with Calliscelio remigio and is intended to be used as a noun in apposition.
