Srivastavanema cynocephali n. sp. (Nematoda, Trichostrongylina, Heligmosomoidea), a parasite of a dermopteran from Indonesia.
Srivastavanema cynocephali n. sp., a parasite of Cynocephalus variegatus (Dermoptera) from Indonesia, is described. This species is closely related to S. yapi Durette-Desset & Lim Boo Liat, 1975, in the characters of the synlophe at the mid-body and in the shape of the caudal bursa, but it is distinguished by the pattern of the synlophe in the posterior part of the body, very long, thin rays 2 and 3, a less developed genital cone, the absence of a membrane between left and right rays 6, and longer spicules. Its morphology is slightly less specialised than the four previously known species of the genus, which are all parasites of petauristines. The genus Srivastavanema (Singh, 1962) has a systematic position between the Heligmonellinae and the Brevistriatinae. Therefore, it may be a parasite of the Dermoptera which could have secondarily evolved within the Petauristinae. The Dermoptera may have played an important role in the evolution of the Heligmonellinae.
