Yunga coriacea (Stål, 1864) View in CoL

( Fig. 2G–H View FIGURE 2 , Fig. 5 View FIGURE 5 )

External morphology. Characters of external morphology as in generic description by Young (1968: 57–59).

Female genitalia. Characters of the female genitalia as in the description of the female of Y. cartwrighti above, except for: Abdominal sternite VII ( Fig. 5A View FIGURE 5 ) approximately 1.2 times wider than long; lateral margins parallel, without lobes; posterior margin with lateral corners slightly angulate, paired V-shaped concavities near median projection, median triangular projection prominent with rounded apex. First valvifer ( Fig. 5C View FIGURE 5 ), in lateral view, almost oval with dorsal margin with shallow concavity. First valvula ( Fig. 5C–D View FIGURE 5 ), in lateral view, with apex acute. Second valvula ( Fig. 5 E–F View FIGURE 5 ), in lateral view, distinctly expanded beyond basal curvature with basal third distinctly higher and narrowing in height towards apex; dorsal margin with 52 separated teeth, each triangular at basal half and subquadrate at apical half; preapical prominence not distinct; apex acute, with ventral margin smooth ( Fig. 5E–F View FIGURE 5 ).

Remarks. Here, we provide for the first time a specific locality record of this species in Mexico. In general, features of the female genitalia of this species are very similar to those of Y. cartwrighti , however, they can be easily distinguished by the shape of the posterior margin of the sternite VII and shape of the second valvula of the ovipositor, thus carrying taxonomic information that may be of importance for future studies in different areas using comparative morphology.

Examined material. MEXICO: 1 female “El Fortin\ Veracruz, MEX\ vii:9:41”; “Col by\ H. Dybas ”; “Fld Mus” ( FMNH) .
