A new species of pygmy mole cricket (Orthoptera: Tridactylidae) from the Lake Wales ridge of Florida and new records of Ellipes eisneri from the northern Brooksville ridge

Pygmy mole crickets (Orthoptera: Tridactylidae) are usually associated with the edges of ponds and streams, but in the sandy uplands of Florida, at least two lineages of these insects have evolved to live in xeric scrub and sandhill habitats. Very little work has been done with scrub tridactylids since they are tiny and often difficult to collect. In this paper, the pygmy mole cricket Ellipes deyrupi sp. nov. is described from the northern Lake Wales Ridge of Florida. It is sympatric at all known locations with another scrub tridactylid, Neotridactylus archboldi Deyrup & Eisner, but has not been found co-occurring with the closely related Ellipes eisneri Deyrup. The habits of this new species are convergent with both N. archboldi and E. eisneri. In addition, new records of Ellipes eisneri are presented, extending this species’ known distribution to the Northern Brooksville Ridge. Both species of scrub Ellipes are found in restricted geographic ranges and suffer from a lack of study and recognition. Conservation implications for these two species are discussed.
