Scaptomyza kamohoalii Rampasso & O’Grady , sp. nov.

( Fig. 20 )

Diagnosis. Male terminalia dark. Surstylus is large and semi-circular, with a well-developed ventral lobe in posterior view. A row of 11 surstylar teeth is distributed in the dorsal portion of the surstylus.

Description. Male (n = 1). Head. Pedicel and first flagellomere brown. Dorsal and ventral of the arista damaged. Terminal fork about 35% as long as basal segment of arista. Eyes dark red and face light brown. Frontal vitta, in the region around the ptilinal suture is light brown, becoming dark brown and gray pollinose in the interorbital area. Frontal triangle, fronto-orbital plates, and ocellar triangle dark brown in ground color and densely gray pollinose. Anterior reclinate is inserted posterolaterally from the proclinate and posterior reclinate orbitals,close to the proclinate. Anterior reclinate 29% length of proclinate. Proclinate 82% length of posterior reclinate. Gena and mouthparts brown. Subvibrissal setae 43% length of vibrissae. Palps brown with two apical black setae. Thorax. Scutum and scutellum dark brown in ground color and densely gray pollinose. 2 pairs of dorsocentral setae.Acrostichal setae in 4 irregular rows when counted between anterior dorsocentral setae, becoming sparse posteriorly. Basal scutellar setae divergent and apical scutellar setae absent. Pleura dark brown in color and densely gray pollinose. 1 postpronotal and 3 katepisternal setae present. Posterior katepisternal seta damaged. Legs. Predominantly light brown. Most legs are partially or entirely broken. Wings. Hyaline without distinct pattern. Abdomen. Previously dissected. Male terminalia ( Figs. 20 C-E). Male terminalia very dark. Epandrium broad, with a ventral lobe. Surstylus is large and semi-circular, with a well-developed ventral lobe in posterior view. The surstylar dorsal lobe projects posteriorly. A row of 11 surstylar teeth is distributed in the dorsal portion of the surstylus. A group of long bristles is found in the ventral lobe. Cerci densely setose. Bristles of cerci and surstyli are very long. Measurements. TL = 0.89 mm; WL = 2.36 mm; TL/WL = 0.40; HW/TL = 0.60; CI = 3.79; 4V = 1.45; 5X = 1.28; 4C = 0.61; M = 0.37.
