description: Guapinannus castigatus, sp. n.
(Figs 2, 7, 9)
Holotype. Male. MEXICO: Chiapas: Palenque, 15.63333°N 92.65°W, 2500m, 02 Jul 1983 – 30 Jul 1983, S. B. Peck, J. Kukalova-Peck, R. S. Anderson, 1♂ (UCR _ ENT 00101251) (FMNH).
Etymology: Named for the stout vesica after “castigatus” Latin for stout.
Diagnosis: Recognized by the mid-sized body length (1.48 mm), elongate oval forewing outline, wide C+Sc (black arrow), small vein-tracing areoles along scc, rc, rc1 (white arrow) (Fig. 2), slightly extended right pygophore margin (black star), vesica relatively short and thick, tapering into acute tip, and without anophoric process (Fig. 7). Similar to G. auriculus, sp. n. in length and shape of vesica but differentiated by differentiated from that species by the slender and long rc1.
Description: Male: Total body length 1.48 mm; length from posterior margin of pronotum to posterior wing margin 1.27 mm; greatest width across pronotum 0.66 mm; greatest width across forewings 0.88 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 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 pointed. Forewing: With outline elongate oval; membrane contributing about one third of forewing length, posterior distal margin squarish, vein-tracing areoles on proximal part of wing present; areoles small, distributed along scc, rc, rc1, and tc; C+Sc broad, wider at widest part of wing; distal process of R pronounced; An1 wing organ on corium strongly inflated, elongate, with median notch, without notch articulating with claval process; scc about 2 times as wide as long; rc1 about 3 times as long as wide, slightly wider anteriorly; rc about 4 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 relatively wide and short. Legs: Claws long. Genitalia (Fig. 7): Pygophore with slightly extended right margin; vesica with about half loop, not reaching right pygophore margin, thick at midpoint, tapering to acute tip, close to apex rounded; anophoric ridge without process; right paramere curved, tapering, basal process narrow; left paramere straight, tapering, basal process narrow.
Female: Unknown.
Collecting method and habitat: Collected using flight intercept trap in rainforest.
