Fulgenta plumosa sp. nov.

( Figs. 39–43 View FIGURES 39 – 43 )

Description. Male: Head: Eyes bare. Frons black and pollinose, narrowing significantly from ocellar triangle to antennal bases where it is 0.3x eye width, frontal and interfrontal setulae very short. Orbital plate shining, broad, bare apart from orbital seta. Lunule ground colour orange with overlying silver dusting, in dorsal aspect parafacials and face margins slightly silver pollinose. Anterior genal setulae in a single row of 5 along mouth margin, becoming weaker anteriorly, no genal setulae particularly long or strong. Antennae entirely black, 1st flagellomere length to depth ratio 2:1. Arista short plumose, ratio of plumosity at maximum extent to depth of 1st flagellomere 0.5:1.

Thorax: mesonotum glittering dark green. Anepisternum with 1 anterodorsal and 2 strong posterior setae. Katepisternum with 1 strong seta. One setae on both proepimeron and proepisternum. Scutellum with disc glittering dark green, margin with 1 small setulae on each side between lateral and apical setae, 0 between apical setae. Calypteres pale with whitish fringes. Wings uniformly light fumose, veins light brown, wing length 2.8mm. Legs black, all tarsomeres pale yellow. Abdomen: tergites coppery-green and heavily dusted.

Male terminalia:; Epandrium; in 9th and 10th terga not completely fused, 9th terga a rather large square-shaped lobe attached to anterior surface of, and approximately half as wide as 10th terga, 10th terga long and narrow, approximately 4x as wide as high, bearing a row of regularly spaced short setulae along posterior margin. Cerci extending almost to posterior margin of epandrium. Apically with a small medial pointed process, covered in short setulae. Surstyli a small lobe with short apical setulae completely enclosed within shell of epandrium. Phallus, basiphallus cuboidal, bearing a group of six small processes in a vertical line on each of the ventral angles, apical portion long, narrow and sinuate, with a thicker sheath on basal third.

Differential diagnosis. this species shows similarities to F. complexa sp. nov. in that the cerci are relatively small, the surstyli relatively well developed and the phallus has a cuboidal basal section with serrated processes. The phallus and the cerci are however easily distinguished from that species.

Etymology. the specific epithet refers to the plumosity of the arista.
