Psilota  sp. 88–38 Thompson, unpublished

Diagnosis: Strongly iridescent over entire body, blue and green thorax and red and green abdomen. Hind leg simple. Body length: 10.4–12.3 mm.

Description: MALE: Head: Frons and face shining metallic blue and green, bare of pollinosity. Face, frons, and vertex with long white pile. Antenna orange. Eye densely pilose, pile entirely white. Thorax: Thorax entirely iridescent blue and green, shining, pollinosity free. Legs dark blue, orange at extreme apex of femora and base of tibiae. Hind femur unmodified, with only a few weak, black setulae apicoventrally. Pleuron white pilose. Scutum mostly white pilose, with some black pile laterally ventrad of transverse suture. Scutellum white pilose, with distinct marginal sulcus. Wing colourless, entirely bare. Abdomen: Tergites entirely iridescent green and red. Tergites 2–3 with some short dark pile on disc, all tergites white pilose laterally. Tergite 4 entirely white pilose. All sternites iridescent blue and red. Genitalia: Epandrium compact, about as long as tall. Cercus approximately triangular. Outer lobe of surstylus inserted at about mid-height of inner lobe, abruptly curved downwards at base. Inner lobe of surstylus broad, approximately 3 times as long as wide, swollen at base, slightly constricted, and smoothly rounded at apex. Phallapodeme smooth, postgonite not darkened.

FEMALE: Identical except for normal sexual dimorphism.

Etymology: The specific epithet metallica  derives from the Latin “metallicum”, meaning “metal”. This is in reference to the strongly iridescent cuticle of Psilota metallica  sp. nov.
