Stridulatory Apparatus

Ensiferan insects (crickets, katydids, grigs and allies) are well known for rubbing parts of their cuticle together to produce sound: a process called stridulation. In this article Swedish entomologist Kjell Ander describes a novel (at the time) stridulatory apparatus in the great grig, Cyphoderris monstrosa (Prophalangopsidae), a relict ensiferan found in the mountainous regions of western North America. Ander used preserved specimens to predict the sound-producing function of a pair of abdominal file-scraper apparatuses, although he was never able to directly test his proposed mechanism nor did he speculate as to the adaptive significance of the structures. The article concludes with a review of the systematic placement of various higher level taxa within the order Orthoptera, of which Ensifera is one suborder.

By using morphology, karyology, pollen size, leaf flavonoids, ecological observations, and modification experiments, a new classification of the Galium trifidum group is proposed. Nine taxa in five species are recognized: (1) G. tinctorium, with ssp. tinctorium and sap. floridanum (new comb.) in eastern North America; (2) G. brevipes, a rare species centered in the Great Lakes region; (3) G. trifidum, with ssp. trifidum in northern North America. Asia, and Europe, ssp. columbianum (new comb.) in (north)western North America and (north)eastern Asia, and ssp. subbiflorum (new comb.) and ssp. halophilum (new comb.) in northern North America; (4) G. innocuum in southeastern Asia; (5) G. karakulense in central Asia.New chromosome counts of n = 12 and 2n = 24 are reported for G. tinctorium ssp. tinctorium and ssp. floridanum; and G. trifidum ssp. trifidum, ssp. columbianum, and ssp. subbiflorum.

A New Species

The genus Admetovis Grote is revised. Admetovisicarussp. n. is described from the mountains of western North America. A lectotype of Admetovisoxymorus Grote is designated. Illustrations of the adults, male and female genitalia, and distribution maps are presented, together with an identification key. The classification of the genus is reviewed resulting in its reassignment to the tribe Hadenini from Orthosiini.

Two New Species

AbstractLarvae, deutonymphs, and male and female adults of Platyhydracarus juliani sp.nov., and adults of P. parvipalpis sp.nov., are described from rheocrenes and small streams in western North America. The genus Platyhydracarus gen.nov. is proposed and diagnosed, based primarily upon the presence of genital acetabula both in the gonopore and on acetabular plates flanking the gonopore, and of a group of thickened setae anterior to the gonopore, in male adults. Possible relationships between Platyhydracarus and other Athienemanniidae are discussed, and a new key to the genera of Athienemanniinae is presented.
