Scaptomyza hinae R ampasso & O’Grady, sp. nov.

( Fig. 24 )

Diagnosis. Surstylus is strongly curved in posterior view. The surstylar dorsal lobe is blunt and extends posteriorly, is shorter than the cercal plates and reaches a similar length as the epandrial posterior lobe A marginal row of seven sharp surstylar teeth is distributed in the middle and ventral portions of the surstylus.

Description. Male (n = 1). Head. Pedicel and first flagellomere black. Arista with 2 dorsal, 0 ventral, and about 4 short inner branches, plus terminal fork. Terminal fork deep, about 50% as long as basal segment of arista. Eyes dark red and face black. Frontal vitta, in the region around the ptilinal suture is black, becoming densely gray pollinose in the interorbital area. Frontal triangle, fronto-orbital plates, and ocellar triangle black in ground color and densely gray pollinose. Anterior reclinate is aligned and inserted halfway between the proclinate and posterior reclinate orbitals. Anterior reclinate 50% length of proclinate. Proclinate 50% length of posterior reclinate. Gena black in ground color and densely gray pollinose. Subvibrissal setae 45% length of vibrissae. Mouthparts dark brown. Palps dark brown with two apical black setae. Thorax. Scutum and scutelum black in ground color and densely gray pollinose. 2 pairs of dorsocentral setae. Acrostichal setae in 6 irregular rows when counted between anterior dorsocentral setae, becoming sparse posteriorly. Basal scutellar setae divergent and apical scutellar setae cruciate. Pleura black in ground color and gray pollinose. 2 postpronotal and 3 katepisternal setae present. Anterior katepisternal setae 61% length of posterior katepisternal setae. Legs. Predominantly black. The front basitarsus is about 35% as long as the tibia. Wings. Hyaline without distinct pattern. The wing was folded, so it was not possible to conduct the morphometry. Abdomen. Previously dissected. Male terminalia ( Figs. 24 C-E). Male terminalia dark. Epandrium is broad, with an anterodorsal phragma and small epandrial posterior lobe. In posterior view, the surstylus is strongly curved. The surstylar dorsal lobe is blunt and extends posteriorly, is shorter than the cercal plates and reaches a similar length as the epandrial posterior lobe. A marginal row of seven sharp surstylar teeth is distributed in the middle and ventral portions of the surstylus. A group of long bristles is found in the ventral portion of the surstylus. Cerci undifferentiated. In lateral view, the cercal plates are two times higher than long.
