Diagnosis
Male. The only species of Downeshelea in the Americas with the following combination of features: gonostylus 0.69 length of gonocoxite; parameres fused for 0.25 of total length, stem sinuous, proximal 2/3 stout, directed posterolaterally, distal 1/3 slender, directed posteromesally; distal portion aculeate ( Figure 9i View Figure 9 ); aedeagus subtriangular, basal arch U-shaped, extending to 0.38 of total length with elliptical sclerotised anterior areas ( Figure 9h View Figure 9 ).
Female. Unknown.
Description
Male. Head. Eyes separated by a distance shorter than one ommatidia; antennal ratio 1.02 ( Figure 7f View Figure 7 ); palpal ratio 1.7 ( Figure 7g View Figure 7 ).
Thorax. Brown, without definite pattern in slide-mounted specimens. Wing ( Figure 7e View Figure 7 )
with greyish spot over CuA, CuA 1, CuA 2 extending into cua 1, anal cell, reaching wing margin, anal cell with greyish area in middle not reaching wing margin; 2 nd radial cell twice longer than 1 st; wing length 1.37 mm; breadth 0.47 mm; costal ratio 0.75. Halter
brown, distal portion of knob darker. Legs ( Figure 7h View Figure 7 ) brown, hind tibia slightly pale
apically. Fore-, hind tarsomere 1 with one basal, one apical spine; midtarsomere 1 with two
basal, two apical, seven other ventral spines; apical spines of tarsomeres 2–4 of fore-, mid-,
hind legs: 2–3–3, 2–2–2, 1–1–1; fore tarsal ratio 2.48, mid tarsal ratio 2.60, hind tarsal ratio
2.49; claws 0.38 length of their respective tarsomere 5.
Abdomen. Dark brown. Terminalia ( Figure 9h View Figure 9 ): tergite 9 with quadrate apex, apicolateral process elongate, slender; sternite 9 slightly concave anteriorly, posterior margin with a poorly developed convex median lobe bearing three long setae. Gonocoxite 2.30 times longer than basal width; gonostylus broader basally, tapering gradually to blunt tip, 0.69 length of gonocoxite. Parameres ( Figure 9i View Figure 9 ) 1.02 times longer than aedeagus fused for 0.25 of total length with short posteromedian projection on the medial fused portion of parameres; knob slender, directed anteriorly; stem sinuous, proximal 2/3 stout, directed posterolaterally, distal 1/3 slender, directed posteromesally; distal portion aculeate, 0.50 of total length. Aedeagus subtriangular, heavily sclerotised laterallly, basal arch U-shaped, extending to 0.38 of total length with elliptical sclerotised anterior areas; distal portion with moderately deep mesal excavation terminating in two sclerotised pointed serrate processes.
Female. Unknown.
