Description.

Female body length: 1.32-1.77 mm (n=20).

Median keel on frons: absent. Sculpture of lower frons: with irregular rugosity medially. Shape of mandible: slender. Median tooth of mandible: diminished. Frons below median ocellus: with 2 rows of setiferous punctures.

Sculpture on posterior half of mesoscutum: coriaceous to rugulose, at most with fine irregular longitudinal sculpture. Sculpture of anterior half of mesoscutellum: uncertain, smooth. Thin median foliaceous lamella on propodeum: absent.

Color of coxae: bright yellow, concolorous with legs.

T1: flat, at most slightly swollen. Anterior margin of T2: with costae or foveolae throughout its width. T2 sculpture: with neither transverse series of small punctures nor scrobiculate lateral areas. Sculpture of T1: costate at sides, smooth medially. Posterior margin of T2: distinctly concave. Number of visible terga past T2: 2 or 3. Setation on T2: limited to at most 1 row of setae posteriorly and sparse setation laterally.

Diagnosis.

Phanuromyia tonsura can be recognized by the sculpture of T1, which is costate laterally and smooth medially.

Etymology.

The name tonsura is derived from the Latin word for a shearing and refers to the tonsure hairstyle often worn by monks, because this species has a smooth “bald” area in the middle of T1. This name is to be used as a noun in apposition.

Comments.

This species most closely resembles P. hjalmr , but the two species can be easily distinguished by their T1 sculpture: P. tonsura has the medial portion of T1 smooth from its anterior to posterior margin, while P. hjalmr is sculptured across the entire anterior third of T1.
