Description.

Body length of female: 3.16 mm (n=1). Color of head: pale 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 to finely punctate. Sculpture of frons below median ocellus: granulate. Sculpture of posterior vertex: granulate. Hyperoccipital carina: absent. Occipital carina medially: complete, strongly crenulate throughout. Length of OOL: less than 0.5 × ocellar diameter. Sculpture of postgena behind outer orbit: granulate. Ocular setae: dense, long. 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.

Color of mesosoma in female: pale brown. Sculpture of dorsal pronotal area: rugose. Sculpture of lateral pronotal area: smooth dorsally, rugulose ventrally. Sculpture of netrion: rugose. Notaulus: percurrent or nearly so. Sculpture of mesoscutum: rugose. Shape of mesoscutellum: semiellipsoidal. Foveolae of scutoscutellar sulcus between notauli: as large as those along margin of axilla. Sculpture of mesoscutellum: densely punctate. Shape of metascutellum: posterior margin straight, approximately 4.0 × wider than long. Sculpture of metascutellum in female: smooth with a longitudinal, median carina. Dorsal propodeum in female: not excavate medially, lateral propodeal carinae meeting anteromedially. Sculpture of dorsal propodeum in female: rugose. Median keels on propodeum in female: present. Mesopleural carina: present. Sculpture of mesepisternum below mesopleural depression: rugose anteriorly, smooth posteriorly. Sculpture of ventral metapleural area: rugose. Color of legs: pale brown. Sculpture of hind coxa: rugose.

Color of fore wing: hyaline. Rs+M: nebulose, weakly pigmented. 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: variably yellow to pale brown. Horn on T1 in female: weakly developed. Sculpture of T1 horn dorsally: rugose. Sculpture of posterior margin of T1 in female: striate rugose. Development of longitudinal striae on T2 in female: reaching posterior margin of T2. Sculpture of T3: largely smooth with submedian longitudinal striae. Shape of T6 in female: distinctly elongate, 2.0 × longer than wide. Sculpture of S3: smooth.

Diagnosis.

This species is most similar to Calliscelio bidens but can be distinguished by its rugose hind coxa and rugose T1 horn in the female.

Etymology.

The epithet refers to the rugose coxa in this species and is intended to be used as a noun in apposition.

Material examined.

Holotype, female: COLOMBIA: Valle del Cauca Dept., 650m, 03°26'N, 76°48'W, Farallones de Cali Natural National Park, 8. V– 19.VI.2001, Malaise trap, S. Sarria, OSUC 458325 (deposited in CNCI).

Comments.

We generally avoided describing two or more new species based on single specimens when they were collected at the same locality and time, which is the case for Calliscelio rugicoxa and Calliscelio bidens , but these two species are easily distinguished from each other (see diagnoses of the two species), and we are convinced they are two different species.
