Description.

Female body length: 2.21-2.50 mm (n=20).

Median keel on frons: absent. Sculpture of lower frons: with multiple transverse rugae; with irregular rugosity. Shape of mandible: slender. Median tooth of mandible: as large as adjacent teeth. Frons below median ocellus: with 2 perfectly parallel 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: rugose-punctate. Thin median foliaceous lamella on propodeum: absent.

Color of coxae: bright yellow, concolorous with legs.

T 1: 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: entirely costate. Posterior margin of T2: straight; only slightly 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 cranos can be recognized by the 2 perfectly parallel rows of setiferous punctures on the frons.

Etymology.

The name cranos is derived from a Greek word for helmet because this species has a large head evoking the image of a knight wearing a helmet. This name is to be used as a noun in apposition.

Comments.

Phanuromyia cranos can be identified most quickly by the distinctive pattern of setiferous punctures on its frons. The setiferous frontal puncture of P. odo may at times appear similar, but P. odo has the apical margin of T2 distinctly concave.
