E-mail: [email protected] The composition, distribution, morphology and bionomics of the cricket subfamily Bothrio- phylacinae are briefly discussed. The following taxa are described and redescribed on the base of type material: Microbothriophylacini Gorochov trib. nov.; Eremogryllodes iranicus Tahami et Gorochov sp. nov., E. persicus Tahami et Gorochov sp. nov., E. p. torangae Tahami et Goro- chov subsp. nov., E. p. lari Tahami et Gorochov subsp. nov., E. dilutus Tahami et Gorochov sp. nov., E. d. bakhtiyari Tahami et Gorochov subsp. nov. and E. bifurcatus Tahami et Goro- chov sp. nov. from Iran; E. b. turcicus Gorochov et Ünal subsp. nov. from Turkey; E. major Chopard from Afghanistan; E. monodi Chopard from North Africa; Bothriophylax kiritshenkoi Gorochov et Tahami sp. nov.; B.? richteri Chopard from Iran; and B. rjabovi Gorochov sp. nov. from Armenia. Key to tribes and genera of Bothriophylacinae is also prepared. Кратко рассмотрены состав, распространение, строение и образ жизни сверчковых под- семейства Bothriophylacinae.
