Figs. 2 View FIGURE 2 A–G; Fig. 9 View FIGURE 9

Diagnosis. Female: This species is easily distinguished by the following combination of characters: palpus 3rd segment swollen, with large, shallow, oval sensory pit on middle of segment; PR 2.6–3.2; long proboscis; mandible with 24 teeth; two unequal spermathecae.

Female. Head. Brown. Eyes bare ( Fig.2 View FIGURE 2 B), narrowly separated, smaller than ½ ommatidium. Pedicel brown, flagellum pale brown, first eight flagellomeres paler on proximal ½; AR 0.98–1.04 (1.0, n=7) ( Fig.2 View FIGURE 2 C); sensilla coeloconica on flagellomeres 1,6–8, two on 1, 6–7 and three on 8. Palpus ( Fig.2 View FIGURE 2 G) brown; 3rd segment swollen, with a large, shallow, oval sensory pit in middle of segment; PR 2.6–3.2 (2.8, n=10). Proboscis long; P/H ratio 1.03–1.16 (1.11, n=11); mandible with 24 teeth.

Thorax. Dark brown. Prominent pattern of yellowish patches well defined ( Fig. 2 View FIGURE 2 F); pale humeral depressions present. Scutum with two pale areas in the anterior submedian portion arranged as leaf clover and two pale areas in posterior submedian portion; lateral portion, with anterior and posterior pale areas; pale prescutellar depressions present; scutellum yellowish laterally; postscutellum brown. Wing ( Fig. 2 View FIGURE 2 A) with contrasting pattern: second radial cell including dark spot; pale spot over R-M extending from M1 to the costal margin, subdivided; r3 with four, small and separated pale spots: first, rounded, between the second radial cell and M1; second, poststigmatic, extendind behind second radial cell, abutting wing margin; third, rounded, in the middle of cell similar to the second one; fourth, distal pale spot slightly reaching wing margin; m1 with two pale spots, the distal one far from wing margin and greater than proximal one; m2 with four pale spots: one proximal, near CuA, two between the medial and mediocubital forks, a distal one not reaching wing margin; cua1 with a rounded and small pale spot in the middle of cell; anal cell with a faint, basal pale area, one distal pale spot near mediocubital fork and one very faint pale spot reaching wing margin, not present in some specimens; wing base with a pale spot on M; M1, M2 and CuA1 with pale apex; macrotrichia scarcely distributed; wing length 0.87–0.95 (0.92, n=10) mm; breadth 0.42–0.47 (0.46, n=10) mm; CR 0.62–0.66 (0.64, n=10). Halter knob brown laterally, stem pale. Legs ( Fig.2 View FIGURE 2 D) mostly brown; femora with subapical pale bands, tibiae with subbasal pale bands; hind tibia pale apically; hind tibial comb with four spines, the one nearest the spur longest.

Abdomen. Brown. Two unequal ovoid spermathecae ( Fig.2 View FIGURE 2 E), measuring 49.7 µm by 35.2 µm (n=10) and 38.2 µm by 28.1 µm (n=9), with sclerotized ducts with 7.5 µm (n=9). Long, slender, rudimentary third spermatheca present (22.5 µm).

Male. Unknown.
