Shape of head: subglobose. Central keel of frons: absent. Setation of upper frons: with sparse, short setae. IOS/EH: IOS distinctly less than EH. Sculpture of ventrolateral frons: smooth to coriaceous. Sculpture of frons below median ocellus: coriaceous. Sculpture of posterior vertex: smooth; smooth to transversely striate. Hyperoccipital carina: absent. Occipital carina medially: interrupted. Length of OOL: less 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: as long as wide. Form of male antennal flagellomeres: filiform, A11 approximately 3.5× 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. Color of mesosoma in male: orange throughout; variably orange to pale brown. Sculpture of dorsal pronotal area: smooth. Sculpture of lateral pronotal area: smooth throughout. Sculpture of netrion: smooth. Notaulus: abbreviated, at most reaching middle of mesoscutum. Sculpture of mesoscutum: granulate. Shape of mesoscutellum: semiellipsoidal. Foveolae of scutoscutellar sulcus between notauli: smaller than those along margin of axilla. Sculpture of mesoscutellum: granulate. Shape of metascutellum: posterior margin rounded, approximately 2.5× wider than long. Sculpture of metascutellum in female: rugulose with a longitudinal, median carina. Sculpture of metascutellum in male: rugose. Dorsal propodeum in female: not excavate medially, lateral propodeal carinae meeting anteromedially. 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: largely smooth with an oblique carina. Color of legs: orange throughout; 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: distinctly shorter than r-rs. Length of R1: greater than 3.0× length of r-rs.
Color of metasoma in female: orange throughout; variably orange to pale brown. Color of metasoma in male: variably orange to pale brown. Horn on T1 in female: absent. 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: present on the anterior margin of T2. Sculpture of T3: smooth. Shape of T6 in female: short, slightly longer than wide. Sculpture of S3: smooth.
Diagnosis
This species shares the character of the abbreviated notaulus with Calliscelio absum and Calliscelio brevinotaulus. It can be separated from Calliscelio absum by having A4 as long as A3 in the female and the length of the A5 tyloid in the male is approximately 0.3× length of A5; from Calliscelio brevinotaulus it may be distinguished by the absence of the T1 horn in the female.
Etymology
The epithet is derived the Greek word for short, in reference to the abbreviated notaulus, and is intended to be treated as a noun in apposition.
