Description.

Female body length: 2.24-2.26 mm (n=2).

Median keel on frons: absent. Sculpture of lower frons: with multiple transverse rugae. 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, rugose-punctate. Thin median foliaceous lamella on propodeum: present.

Color of coxae: bright yellow, concolorous with legs.

T1: with distinct, tubular horn reaching higher than metascutellum. 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: 3 or 4. Setation on T2: limited to at most 1 row of setae posteriorly and sparse setation laterally.

Diagnosis.

Phanuromyia tubulifer can be recognized by the distinct, tubular horn on T1 and the thin foliaceous lamella present medially on the propodeum.

Etymology.

The name tubulifer refers to the presence of the diagnostic tubular horn on T1 in this species. This name is to be used as a noun in apposition.

Material examined.

Holotype, female: GUYANA: Potaro-Siparuni Reg., 100-200 m, 04°40'19"N, 58°41'04"W, Iwokrama Forest Reserve, V-2001 - VI-2001, flight intercept trap, R. Brooks & Z. Falin, OSUC149410 (deposited in CNCI). Paratype: BRAZIL: 1 female, OSUC149411 (CNCI).

Comments.

This species is distinct due to its tubular horn, although it is unknown whether the males express this character to any significant degree.
