Protearomyia rameli  sp. nov.

Description. Male: Head. Eyes bare. Frons matt black, 8–9 frontal setulae approximately one third length of orbital seta, a scattering of shorter interfrontal setulae. Orbital plate not greatly differentiated, subshining, bare apart from the orbital seta. Lunule black, without setulae. Anterior genal setulae forming a single row of 6 along mouth edge, the basal of these the strongest setulae on genae. Antennae entirely black, 1 st flagellomere slightly longer than deep, with rounded apex. Arista yellowish basally, with microscopic pubescence.

Thorax. Thoracic dorsum subshining black, covered in setulae approximately one third length of orbital seta. Anepisternum with no apparent anterodorsal setae, three strong posterior setae. Katepisternum with three setae arranged laterally along dorsal margin, these becoming weaker anteriorly, sclerite otherwise bare. One seta on proepimeron and one on proepisternum. Scutellar disc slightly brown dusted contrasting with blue-black of thorax, four strong marginal setae. Calypteres white with white fringe. Wings slightly whitish, veins yellow. Legs entirely black, fore and hind metatarsi with a dense fringe of pale setulae ventrally.

Abdomen. Tergite 5 4 x length of t 4, apically with marginal comb of 8 short stiff setulae on each side.

Male terminalia ( Figs. 7–12View FIGURES 7 – 12). Epandrium in lateral view ( Fig. 7View FIGURES 7 – 12) twice as wide as high, bearing a row of setulae along the posterior margin, ventral lobe almost same height as epandrium, rectangular in lateral view with a rounded process posteroventrally which bears approximately 8 long, strong, curved setulae, the remainder of the outer surface being covered in very short, rather evenly distributed setulae, inner surface with one short strong setae situated close to where the epandrium overlaps the surstylus. Surstylus ( Fig. 8View FIGURES 7 – 12), outer margin with only slight serrations and a slight projection anteriorly, two large prensisetae posteroventrally, one lying dorsal to the other. Cerci rather small, extending as a triangular process posteriorly from shell of epandrium, bearing a row of setulae along ventral margin. Hypoproct forming a long curving rod through the shell of the epandrium, in posterior view broadening slightly at apex and forming a pair of thin, parallel, ventrally directed projections ( Fig. 9View FIGURES 7 – 12), no ornamentation on these projections apart from a few stiff setulae below. Phallus ( Fig. 12View FIGURES 7 – 12) forming a simple U-shape tube with a long lightly sclerotized apical section, basal plate rectangular, higher than wide. Phallic guide ( Figs. 10 & 11View FIGURES 7 – 12), in lateral view with a pair of blunt slightly curved processes.

Measurements: Body length 3.5 mm Wing length 3.25 mm.

Differential diagnosis: the two long, narrow, parallel processes at the apex of the hypoproct distinguish this species from others with a square ventral lobe of the epandrium.
