Description.

Body length of female: 2.56-2.96 mm (n=16). Body length of male: 2.45-2.70 mm (n=7). Color of head: black throughout. Color of antennal clava (A7-A12): dark brown to black. Shape of head: strongly transverse. 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 longet 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 with longitudinal, median black strip on anterior mesoscutum. Color of mesosoma in male: orange with longitudinal, median black strip on anterior mesoscutum. Sculpture of dorsal pronotal area: smooth. Sculpture of lateral pronotal area: smooth anteriorly, punctate rugulose posteriorly. Sculpture of netrion: rugulose. Notaulus: percurrent or nearly so. Sculpture of mesoscutum: smooth with sparse punctures; 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 punc tures. Shape of metascutellum: posterior margin straight, approximately 3.0 × wider than long. Sculpture of metascutellum in female: finely crenulate. Sculpture of metascutellum in male: finely crenulate. 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 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: variably orange to pale brown. Color of metasoma in male: orange throughout; variably orange to pale brown. Horn on T1 in female: present as a small bulge. Sculpture of T1 horn dorsally: 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. Sculpture of T3: smooth with longitudinal submedian striae. Shape of T6 in female: distinctly elongate, approximately 3.0 × longer than wide. Sculpture of S3: densely punctate; punctate rugose.

Diagnosis.

This species is most similar to Calliscelio pararemigio but can be distinguished by its strongly transverse head and transversely striate small T1 horn in female. In males, it can be separated from Calliscelio pararemigio by the strongly transverse head and the densely punctate or punctate rugose S3.

Etymology.

The specific epithet refers to the locality, Mt. Remigio, on the label of the holotype and should be treated as a noun in apposition.
