Additionally, the antenna is orange; the pubescence on the body is long and black, abundant on the propodeum; the pronotum has the collar differentiated from the disc; the front basitarsus is weakly spined, the spines are in two rows; the wing has the edge of first radial 2 cell rounded; and the fore and hind wings are smoky grey to black with purple reflections. The female (Fig. 3C) has the dorsal face of the hind tibia serrate. The male (Fig. 3B) has the dorsal face of the hind tibia not spinose.</p> <p> <b>Material examined.</b> DOMINICAN REPUBLIC: La Vega, Cordillera Central, 4.1 km SW E1 Convento, 18–50–37N, 70–42–48W, 1730 m, dense secondary evergreen forest with pine, hand collected, sample 22242, J.

Further studies of <i>Entypus</i> in the Caribbean are needed. <i>Pepsis ruficornis</i> is found in dense forests where females run on the ground and seem to check a limited number of areas before abandoning an area; they rarely use dense clusters of leaf litter to search (Vardy 2005). Vardy (2005) also commented on possible aggregations of males at night and the difficulty of observing this behavior due to the preference of this species for forested areas.</p> </body> </html>
