A FAUNISTIC INVENTORY OF THE FAMILY EVANIIDAE (HYMENOPTERA: EVANOIDEA) IN THE STATES OF YUCATÁN AND QUINTANA ROO, MEXICO

Abstract

In the world catalogue of Evaniidae, 435 species are recognized distributed in 20 genera. In Mexico, 14 species are registered distributed in four genera: Evania, Evaniella, Hyptia and Semaeomyia. The distribution records of Evaniidae include the states of Baja California Sur, Tabasco, Morelos and Veracruz. The objective of the present study was to make a faunistic inventory of the family Evaniidae in the states of Yucatán and Quintana Roo. The Evaniidae were collected with a Townes type Malaise trap. The sampling was carried out from 1993 to 1999 and 2006 to 2009, and the material was obtained from the traps every 15 d in 19 localities of Yucatán: Celestún, Conkal, Dzibilchaltún, Dzilam de Bravo, El Cuyo, El Palmar, Tabi, Kabah, Yalahau, Mérida, Mocochá, Put, Quintana Roo, Rancho Hobonil, Ría Lagartos, Sudzal Chico, Teya Pueblo, Tizimín, Xmatkuil, and two of Quintana Roo: Reserva El Edén y Vallehermoso.1,601 specimens of Evaniidae were collected, which were distributed in four genera (Evania, Evaniella, Hyptia, Semaeomyia) and 11 morphospecies. These specimens belong to a species close to Evania albofacialis Cameron, and they were obtained from four taxa of Hyptia reticulata of which the following were determined: H. ocellaria (Schletterer) and H. petiolata (Fabricius), plus two morphospecies related to Semaeomyia Bradley, 1908. The majority of species collected exhibited wide distribution in the states of Yucatán and Quintana Roo.
