The first live photos of the canyon pygmy mole cricket, Ellipes monticolus Günther, are presented, with preliminary observations on the habitat and behavior of populations in the Chiricahua Mountains of southeastern Arizona. The species was previously known solely from the original description in 1977, which included only drawings of the structure of the genitalia and almost no natural history information. This paper provides the first look at this species’ biology and provides a framework for future studies on Tridactylidae of the southwestern United States.

In different insect taxa, ears can be found on virtually any part of the body. Comparative anatomy and similarities in the embryological development of ears in divergent taxa suggest that they have evolved multiple times from ubiquitous stretch or vibration receptors, but the homology of these structures has not yet been rigorously tested. Here we provide detailed analysis of a novel set of hearing organs in a relatively “primitive” atympanate bladder grasshopper (Bullacris membracioides) that is capable of signaling acoustically over 2 km. We use morphological, physiological, and behavioral experiments to demonstrate that this species has six pairs of serially repeated abdominal ears derived from proprioceptive pleural chordotonal organs (plCOs). We demonstrate continuity in auditory function from the five posterior pairs, which are simple forms comprising 11 sensilla and resembling plCOs in other grasshoppers, to the more complex anterior pair, which contains 2000 sensilla and is homologous to the single pair of tympanate ears found in “modern” grasshoppers. All 12 ears are morphologically differentiated, responsive to airborne sound at frequencies and intensities that are biologically significant (tuned to 1.5 and 4 kHz; 60–98 dB SPL), and capable of mediating behavioral responses of prospective mates. These data provide evidence for the transition in function and selective advantage that must occur during evolutionary development of relatively complex organs from simpler precursors. Our results suggest that ancestral insects with simple atympanate pleural receptors may have had hearing ranges that equal or exceed those of contemporary insects with complex tympanal ears. Moreover, auditory capability may be more prevalent among modern insect taxa than the presence of overt tympana indicates

The first annotated checklist of the short-horned Orthoptera (Caelifera) of Tuva and adjacent territories is presented. This list is based on numerous published and unpublished data. A total of 42 species belonging to 3 families, namely Tetrigidae (6), Tridactylidae (1), and Acrididae (35 species from the subfamilies Melanoplinae and Calli- ptaminae and from the gomphocerine tribes Chrysochraontini, Arcypterini, Aulacobothrini, and Stenobothrini), are known as occurring in Tuva. Seven species are recorded from the region for the first time, namely Tetrix similans (Bey-Bienko), Zubovskya koeppeni (Zubovsky), Podismopsis poppiusi (Miram), P. jacuta Miram, Stenobothrus nigromaculatus (Herrich-Schäfer), S. carbonarius (Eversmann), and Omocestus petraeus (Brisout de Barneville). Zubovskya mongolica Storozhenko, comb. resurr. is mentioned for the southern part of the Republic of Khakassia for the first time. The first record of Podismopsis jacuta Miram in Krasnoyarsk Region is also published. At least three species are known from the adjacent areas and listed as probably occurring in the region.

A review of vibration communication in suborder Caelifera is made. The vibration communication channel is found in three superfamilies—Tetrigoidea, Eumastacoidea and Acridoidea. The presence of vibration communication in Pyrgomorphoidea and Tridactyloidea is suggested. The data on vibration signals in superfamilies Pneumoroidea, Tanaoceroidea and Trigonopterygoidea are not known.
