Description
Body length of female: 1.95–1.99 mm (n=20). Body length of male: 1.90–2.05 mm (n=2). Color of head: brown throughout; orange throughout; orange to pale brown. Color of antennal clava (A7–A12): dark brown to 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: smooth; smooth to coriaceous. Sculpture of posterior vertex: granulate to rugulose. 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: largely smooth with small granulate area. Ocular setae: absent. A4 in female: distinctly longer than 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; orange to pale brown; dark brown. Color of mesosoma in male: dark brown 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. 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: smooth. 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 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: 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: anterior margin of T2 and T6 yellow, otherwise brown. Color of metasoma in male: anterior margin of T2 yellow, otherwise brown to black. 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: smooth medially, longitudinally striate laterally. 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: distinctly elongate, approximately 2.0× longer than wide. Sculpture of S3: largely smooth with sparse and fine punctures.
Diagnosis
Females of this species are most similar to Calliscelio migma in size and habitus but can be distinguished by the strongly foveolate scutoscutellar sulcus and the smooth T3. Males of Calliscelio flavicauda are similar to Calliscelio laticintus and Calliscelio longius. It may be separated from Calliscelio laticinctus by the smooth T3 and the brown hind femora, from Calliscelio longius that A11 is approximately 3.0× longer than wide.
Etymology
The specific epithet meaning “yellow tail” refers to the yellow T6 in female and should be treated as a noun in apposition.
