Insulestremia amorimi View in CoL sp. n.

( Fig. 1 View FIGURE 1 )

Diagnosis. Male Terminalia ( Fig. 1A View FIGURE 1 ). Gonostyli lobes with less than half length of gonocoxites; main lobe subtriangular, rounded apically and bearing a single megaseta, slightly bent inwards; side lobe longer than the main lobe, with small, spine-like tooth surrounded by short spines at apex. Tegmen 2.5 times longer than width of base, rounded at apex. Ejaculatory apodeme long, thin, sclerotized on basal half.

Description. Male. Body length: 1.24–1.49 mm. Wing length: 1.28–1.53 mm; wing width: 0.49–0.67 mm. Pattern of tergal plaques: 0/1/1/1/1/1/1/0. Flagellomere 4 with three long and flattened sensilla at the apical third, distributed as two at ventral surface and one at dorsal surface; sensilla with length four times longer than base width; flagellomere 3 ( Fig. 1B View FIGURE 1 ) with one flattened and two pointed sensillum arising from a very large pore. Terminalia. Gonocoxites with dorsomedial lobe variable in size and sclerotization; dorsal transverse bridge at the level of parameral apodemes. Tergite 9 as a wide, short plate. Cerci tapered toward apex, reaching three-quarters length of tegmen.

Female. Body length: 1.95 mm. Wing length: 1.62 mm; wing width: 0.62 mm. Head: Antennae incomplete; flagellomere ( Fig. 1C View FIGURE 1 ) with very short stem and barrel-shaped node; node with 2 flattened, two- to four-pointed sensilla arising from very large basal pores; setae around base of node oversized as in comparison with male.

Immature stages. Unknown.

Etymology. The species epithet is to honors the dipterist Dr. Dalton de Souza Amorim, who has been one of the greatest contributors to the knowledge of the Neotropical Diptera and opened the laboratory under his supervision to several visits of AMCN.
