Downeshelea litorale sp. nov. (Figures 6a–h, 9c–d, 10) Downeshelea multilineata : Huerta et al. 1999: 494 (misidentification; Mexico record). Diagnosis Male. The only species of Downeshelea in the Americas with the following combination of features: gonostylus 0.58–0.68 length of gonocoxite; parameres fused for 0.23–0.30 of total length; stem nearly straight basally, expanded distally in inner portion; distal portion very elongate, strongly curved distally (Figure 9d); aedeagus rectangular, basal arch somewhat U-shaped, extending to 0.34–0.42 of total length (Figure 9c). Female. The only species of Downeshelea multilineata group in the Americas with medium-sized wing (1.05–1.25 mm) (Figure 6d); midtarsomere 1 with 4–5 ventral spines; hind tibia uniformly brown; two slightly unequal spermathecae (Figure 6h). Description Male. Head . Eyes slightly contiguous in lower area; antennal ratio 1.00–1.07 (1.02, n = 8); palpal ratio 2.20–2.75 (2.46,n = 8) (Figure 6b). Thorax. Brown, without definite pattern in slide-mounted specimens. Wing (Figure 6a) with greyish spot over CuA 1, CuA 2 extending into cua 1, anal cell, reaching wing margin in CuA 1; 2 nd radial cell twice longer than 1 st; wing length 1.00–1.17 (1.08, n = 8) mm; breadth 0.32–0.40 (0.37, n = 8) mm; costal ratio 0.71–0.75 (0.73, n = 8).
