Morphology, bioacoustics and phylogeography of the Isophya major group (Orthoptera: Tettigoniidae: Phaneropterinae): A species complex occurring in Anatolia and Cyprus

Abstract

Abstract. The species of the Isophya major-group (Orthoptera: Tettigoniidae: Phaneropterinae), are reviewed. I. major Brunner von Wattenwyl and I. mavromoustakisi Uvarov are redescribed. Two new species are described; Isophya mersinensis Sevgili & Çıplak sp. n. and Isophya salmani Sevgili & Heller sp. n. from south Anatolia. Illustrations of morphology and male calling song are provided and a detailed comparison of the four species in the group is presented. We conclude that these four species constitute a natural group in sharing male cerci with two or more denticles not ordered in a line, a character unique to this species group within the genus. From an evaluation of their morphology and song characteristics, relationships among the species in the group are I. major + (I. mersinensis sp. n. + (I. salmani + I. mavromoustakisi). Based on the the distribution pattern and habitat preference, we concluded that the division of I. salmani and I. mavromoustakisi was a vicariant event resulting from the separation of Cyprus and Anatolia due to reflooding of the Mediterranean after the Messinian salinity crisis at the beginning of the Pliocene, around 5 My ago.

A comparative study of genome organization and inferences for the systematics of two large bushcricket genera of the tribe Barbitistini (Orthoptera: Tettigoniidae: Phaneropterinae)

“…The first column shows groups of species/phylogenetic lineages as suggested in published sources and/or inferred from unpublished own data: 1 – I. straubei group [5]; 2 – I. rectipennis group [5]; 3 – I. modesta group [5]; 4 – I. pyrenaea group [5]; 5 – I. costata group [5]; 6 – I. kraussii group [5]; 7 – I. zernovi group [46]; 8 – I. schneideri group [5,46]; 9 – I. speciosa group [5]; 10– I. major group [12]. …”

Comparative analysis of the location of rDNA in the Palaearctic bushcricket genus Isophya (Orthoptera: Tettigoniidae: Phaneropterinae)

“…In spite of the existing comprehensive bioacoustic and morphological (e.g. Heller et al, 2004;Sevgili et al, 2006), classical cytogenetic (e.g. Warcha owska-liwa et al, 2008) and molecular studies (Grzywacz & Warcha owska-liwa, 2008;GrzywaczGiba a et al, 2010), the relationships within the group are still poorly known.…”

A New Species of the GenusPterodichopetala(Orthoptera: Tettigoniidae: Phaneropterinae) from Northeastern Mexico

“…The terminology for the descripThe terminology for the description of acoustic signals follows Ragge & Reynolds (1998), Gerhardt & Huber (2002), Sevgili et al (2006), and Orci et al (2010). Calling song: song produced by a single male; syllable group (echeme): an assemblage of syllables; syllable: sound produced during one opening and closing movement of the tegmina; impulse: a simple, undivided transient train of sound waves (here: the highly dampened sound impulse resulting from the impact from one tooth of the stridulatory file).…”
