New taxa of Mirolliini from South East Asia and evidence for an abdominal gland in male Phaneropterinae (Orthoptera: Tettigoniidae)

Abstract

Identification of various unworked museum specimens and newly received material from Sabah, Peninsular Malaysia, Singapore, North Thailand, and North East India resulted in the discovery of new taxa of Mirolliini. Two genera and twelve species are described as new: Amirollia gen. n. (type species A. furcata sp. n.), Hemimirollia gen. n. (type species Mirollia gracilis Karny, 1925); Amirollia furcata sp. n.; Deflorita marginata sp. n., D. protecta sp. n., Hueikaeana andreji sp. n., H. quadrimaculata sp. n., Mirollia forcipata sp. n., M. malaya sp. n., M. paralata sp. n., M. rumidi sp. n., M. secunda sp. n., M. spinulosa sp. n., and M. tawai sp. n. Four new combinations are proposed: Mirollia gracilis Karny, 1925 and M. luteipennis Karny, 1925 are combined with Hemimirollia; Mirollia ulla Gorochov, 2008 is combined with Amirollia; Hueikaeana decora Gorochov, 2008 is combined with Deflorita and the male described for the first time. The females of2 · Zootaxa 2943 © 2011 Magnolia PressDeflorita bella Gorochov, 2008 and Mirollia longipinna Ingrisch & Shishodia, 1998 are described for the first time. Stridulation of M. secunda sp. n. is reported. The study also revealed formerly unreported modifications of the anterior abdominal tergites in males of all species under study, which are interpreted as abdominal glands.
