Detection of the Spider Predator, Hololena Nedra By Naïve Juvenile Field Crickets (Gryllus Integer) Using Indirect Cues
2004
Summary In many species, prey detect predators using chemical cues, which may be based on the predator’s previous diet. Furthermore, the predator’s previous hunting strategy and diet may affect the prey’s behavioural strategies to avoid predation. Juvenile Gryllid field crickets face predation by spiders, but the responses of juvenile crickets to spiders are unknown. We studied whether naive juvenile field crickets can detect a predatory spider, Hololena nedra, using chemotactile cues (silk, secretions and excreta). We also studied the effect of the predator’s diet on the juvenile field cricket’s anti-predator behaviour. Cricket nymphs avoided the chemotactile spider cues when the spiders w…
New and little known species of the genus Parapholidoptera Maran (Insecta, Orthoptera)
2009
Material of species of the genus Parapholidoptera Maran is presented. New records of P. noxia (Ramme) are reported from Georgia, P. georgiae sp. n. from Georgia and P. kalashiani sp. n. from Armenia are described. P. syriaca is newly reported from Lebanon.

Tettigoniidae (Orthoptera) from Jordan with description of new species and redescription of less known species
2001
Twenty species of Tettigoniidae are recorded from Jordan, 13 of them for the first time. Two new species are described, Uvarovistia rammei and Parapholidoptera willemsei. New status is proposed for Paradrymadusa philbyi Uvarov (= Scotodrymadusa philbyi) and for Platycleis (Incertana) erecta Uvarov (= Platycleis (Decorana) erecta).
New and less known Orthoptera (Insecta) from the island of Socotra (Yemen)
2009
A list of nine species of Orthoptera collected on Socotra is reported. Three of them were previously unrecorded on the island (Trigonidium cicindeloides, Paratettix subpustulatus and Acrotylus insubricus) and one (Ochrilidia socotrae n.sp.) was undescribed. Further systematic notes on Glomeremus pileatus, G. mediopictus, Pyrgomorpha conica tereticornis, Acrotylus incarnatus and Sphingonotus insularis are included. The East African Acrotylus meruensis, previously considered synonym of A. incarnatus, is proposed as a valid species, distinct from the latter.
The genus Troglophilus Krauss, 1879 (Orthoptera: Rhaphidophoridae) in the west Balkans
2011
We present a revision of the genus Troglophilus in the western part of the Balkan Peninsula based on morphological and genetic analysis, and provide distribution data for the species. The results of these analyses reduced the number of the known taxa within the genus Troglophilus in this area to five valid species: Troglophilus cavicola (Kollar, 1833), Troglophilus neglectusKrauss, 1879, Troglophilus ovuliformisKarny, 1907, Troglophilus brevicauda Chopard, 1934, and Troglophilus lazaropolensis Karaman, 1958. A new species Troglophilus zorae sp. nov. is described and Troglophilus neglectus serbicus Maran, 1958, Troglophilus neglectus vlasinensis Maran, 1958, Troglophilus bukoviki Karaman, 19…
Courtship song and immune function in the field cricket Gryllus bimaculatus
2003
It has been assumed that sexual ornaments have evolved to reveal males’ health and vigour for females. Choosy females may indirectly use ornaments as an indicator of the presence and effectiveness of genes for resistance against parasites. In this study we tested whether females of the Mediterranean field cricket, Gryllus bimaculatus, can use courtship song as a cue for choosing males with high immunocompetence, measured as encapsulation rate of nylon implants and lytic activity of haemolymph. We found that female crickets preferred courtship songs from males with a high encapsulation rate. Female crickets also had a tendency to prefer courtship songs with high tick rate and long high-frequ…
DNA Extraction From Orthoptera Museum Specimens
2011
We describe a procedure for rapid purification of high quality DNA from either fresh or dry Orthoptera, suitable for the PCR amplification of DNA regions more than 800 bp long (even from oldest specimens), which allows genetic analyses on animals from collections without the complete specimen disruption.
New species, records and synonymies of West Palaearctic Pamphaginae (Orthoptera: Caelifera: Pamphagidae)
2012
The author analyses the species of some West Palaearctic genera of Pamphaginae, namely Euryparyphes, Paraeuryparyphes, Glauia, Pseudoglauia, Glauvarovia, Prionosthenus, Lativertex, Ocnerosthenus, establishing the following synonymies: Euryparyphes olcesei (Bolivar 1907) = Euryparyphes bolivari (Stål 1876); Euryparyphes paraflexuosus La Greca 1993 = Euryparyphes flexuosus Uvarov 1927; Glauia durieui rubripes Morales Agacino & Descamps 1968 = Glauia durieui durieui (Bolivar 1878); Prionosthenus lebanicus Dirsh 1950 = Prionosthenus femoralis Werner 1938; Prionosthenus (Lativertex) Koçak & Kemal 2011 = Paranothrotes Mishchenko 1951. Further, the author confirms the synonymies: Euryparyphes vauc…
Pseudorhynchus raggeanus nomen novum

Massa, Bruno (2021): Pseudorhynchus raggeanus nomen novum. Zootaxa 4991 (3): 592-592, DOI: https://doi.org/10.11646/zootaxa.4991.3.9
Annotated Check-List of Orthoptera of Libya
2009
Abstract A list of Libyan Orthoptera is presented based on specimens preserved in Museums, incorporating all (previously published or unpublished) label information. Overall, 141 species are included, of which four are new records for the country. Given within “species inquirendae” are another six species, with the reasons for confirming their presence. Libya's orthopteran fauna is probably not rich, but our knowledge of it is far from exhaustive.
