A revision of the mygalomorph spider genus Neocteniza (Araneae, Actinopodidae). American Museum novitates ; no. 2603

Abstract

"The seven known species of Neocteniza are diagnosed and described; a male of the genus is reported for the first time. On the basis of shared derived characters it is concluded that the Actinopodidae and Migidae are sister groups and that of the three known genera of Actinopodidae, Actinopus and Missulena together constitute the sister group of Neocteniza. The genitalia of Neocteniza, particularly of the male, are of extraordinary complexity for mygalomorph spiders, and suggest that males can mate only once and females only once during each adult instar. Five new species are described: N. pococki from Venezuela, N. fantastica from Colombia, N. osa from Costa Rica, N. subirana from Honduras, and N. paucispina from Guatemala. Genitalic and somatic characters of the group are illustrated in detail for the first time"--P. [1].
