Family Xiphocentronidae Ross

Living species of Xiphocentron (type species: Xiphocentron bilimekii Brauer ) are known from the southwestern USA through Central America and the Caribbean ( Mexico, Nicaragua, Costa Rica, Panama, and Cuba) into South America ( Flint et al. 1999). Adults lack ocelli. The maxillary palps are elongate with terminal segment 5 equal to or greater in length than segments 1–4 and with suture-like cross striae. The mesoscutal setose warts are quadrate. The genus is further characterized by the forewing venation ( Schmid 1982): Sc is fused to R 1 at crossvein r 1 -sr, forks 1, 2, and 4 are present, the discoidal and thyridial cells are closed, the median cell is open, and Cu 2 and A 1 reach the wing margin separately. The foreleg has 0, 1, or 2 apical tibial spurs, but always lacks preapical spurs; the middle legs have 2 preapical and 2 apical spurs; and the hind legs have 4 tibial spurs in the female, but in the subgenera Xiphocentron and Rhamphocentron some males have 2 preapical spurs and 1 modified apical spur.
