Description.

Female body length: 1.19-1.99 mm (n=6).

Median keel on frons: absent. Sculpture of lower frons: with irregular rugosity; with 3-6 transverse rugae 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: rugose-punctate. 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: evenly costate across anterior 1/3 to 1/2, smooth in remaining apical portion. 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 hjalmr can be recognized by the sculpture of T1, which is evenly costate across the anterior 1/3 to 1/2 and smooth in remaining apical portion, combined with the distinctly concave posterior margin of T2.

Etymology.

The name hjalmr is derived from the Old Norse 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.

This species most closely resembles P. tonsura , but the two species can be 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.
