NEW SPECIES OF THE FAMILY RAPHIDIIDAE FRO M MEXICO AND EVIDENCE OF A SPERMATOPHORE IN THE ORDER RAPHIDIOPTERA (INSECTA, NEUROPTEROIDEA)

In a living couple (reared from larvae) of Alena (Aztekoraphidia) infu ndibulata n.sp., a species recently discovered in Mexico, a spermatoph ore was detected which represents the first documented finding within the ordo Raphidioptera. This spermatophore is figured, its position wi thin the categories of spermatophores as defined by Gerber [1 970] is discussed. A. infundibulata n. sp. is closely related to Alena (Azteko raphidia) caudata (Navas 1914) and Alena (Aztekoraphidia) schremmeri n .sp. The 2 new species are described and figured (alae, male and femal e genital structures, larvae). The larvae are the first records of ear ly stages of Alena Navas 1916. a genus with an isolated position withi n the family. So far both species have been found in the S of Mexico ( State of Oaxaca) only. They represent the southernmost records of exta nt representatives of the family Raphidiidae in the world.
