Holotype. Male. MEXICO: Chiapas: RSV A El Triunfo, Est. El Triunfo, 16.20286°N 91.86044°W, 1950 m, 08 Aug 1996 – 11 Aug 1996, A. R. Gillogly, 1♂ ( UCR _ ENT 00094282 ) ( UCR). GoogleMaps

Etymology: Named for the extremely thick vesica after “robustus” Latin for robust.

Diagnosis: Recognized by the mid-sized body length (1.49 mm), small vein-tracing areoles distributed along scc, rc and rc1 (black arrow) ( Fig. 3 View FIGURE 3 ), slight extensions of the right pygophore margin (black star), and very thick vesica with blunt tip ( Fig. 7 View FIGURE 7 ).

Description: Male: Total body length 1.49 mm; length from posterior margin of pronotum to posterior wing margin 1.1 mm; greatest width across pronotum 0.28 mm. General coloration: mix of pale and darker brown or reddish brown. Vestiture: Dorsum with dense setae, setae long; setae on posterior margin of forewing extremely long. Structure: Head: Eye almost half as high as head; muscle scars large. Thorax: Anterior pronotal margin concave, posterior margin slightly concave; pits on pronotum medium-sized, evenly distributed; scutellum in dorsal view gradually narrowed to tip, tip rounded. Forewing: With outline elongate oval; membrane contributing about one third of forewing length, posterior distal margin rounded, vein-tracing areoles small, distributed along scc, rc and rc1; C+Sc broad, wider at widest part of wing; distal process of R pronounced; An1 wing organ on corium strongly inflated, triangular, with median notch, without notch articulating with claval process; rc1 about 3 times as long as wide, slightly wider anteriorly; rc about 5 times as long as wide; tc about 3 times as long as wide; part of An1 and Cu forming posterodistal margin of tc of similar width as other veins; distal margin of rc1, rc, and tc cells double s-shaped; rc2-3 trapezoidal; cub almost reaching wing margin; dc1 with basal portion fairly narrow and elongate.

Legs: Claws long. Genitalia ( Fig. 7 View FIGURE 7 ): Pygophore with slightly extended right margin; vesica with about half loop, not reaching right pygophore margin, very thick at midpoint, tapering to blunt tip, close to apex slightly s-shaped; anophoric ridge with process, process short, with single lobe relatively straight, tip pointed; right paramere curved, broad throughout, basal process broad; left paramere straight, tapering, basal process narrow.

Female: Unknown.

Collecting method: Collected using a flight intercept trap.
