Katydids of Costa Rica / Vol. 1, Systematics and bioacoustics of the cone-head katydids (Orthoptera: Tettigoniidae: Conocephalinae sensu lato). Author Piotr Naskrecki text 2000 The Orthopterists Society at the Academy of Natural Sciences of Philadelphia, Philadelphia, PA book 10.5281/zenodo.270035 647046fe-0ee5-401d-b4f8-aea0355fde7f 270035 Conocephalus sp. cf. spinosus Fig. 39 H Rehn and Hebard (1915b) reported from Costa Rica ( Puntarenas ) a single male of C. spinosus (Morse) , a species otherwise known from salt marshes of California and northern Mexico .After examining the specimen and comparing it to the type specimens of C. spinosus , I came to the conclusion that the two are not conspecific. Despite general similarity, they differ considerably both in the shape of cerci ( Figs. 39 G-H) and the arrangement of teeth on the stridulatory file. It is possible that the Costa Rican specimen represents a yet undescribed species of Conocephalus , but until more material is collected, its status remains uncertain.
