Abstract Description of a new subspecies of Poecilimon mytilenensis Werner 1932. Both the new and the nominate subspecies occur on the island of Lesbos, Greece. Both subspecies differ mainly in the length of the tip of male subgenital plate. In addition to morphological data and a detailed distribution map, descriptions and oscillograms of male song of both subspecies, female song of the nominate subspecies and some data on the unusual mating behavior (ampulla mass 15 % of male body mass) are… 
Integrated systematics of the Poecilimon luschani species group (Orthoptera, Tettigoniidae): radiation as a chain of populations in a small heterogeneous area
The Poecilimon luschani species group (Orthoptera, Tettigonioidea, Phaneropterinae), ranging along a narrow line in West Anatolia and the Balkan mountains, has been revised using integrated data from
Bioacoustics and systematics of the Poecilimon heroicus-group (Orthoptera: Phaneropteridae: Barbitistinae)
TLDR
The diagnostic morphological characters of all these species and the male calling song of three of the four species of the Poecilimon heroicus-group are described and the change in communication from acoustically responding to mute females has not been previously documented within a group of closely related species.
Systematics and bioacoustics of the Poecilimon sanctipauli-group (Orthoptera: Tettigonioidea: Phaneropteridae)
TLDR
A combination of characters by which Poecilimon species can be recognised as members of the P. sanctipauli group are described, most important are the wide fastigium, short ovipositor and song characters.
Phaneropterinae (Orthoptera: Tettigoniidae) from Turkey and the Middle East II
TLDR
A rich and interesting material collected from Turkey and the neighbouring countries including the Middle East has been evaluated and three distinct clades of the species groups of Poecilimon are separated and discussed their taxonomic positions.
Re-evaluation of the genus Phonochorion (Orthoptera: Tettigoniidae: Phaneropterinae)
TLDR
Song structure and morphological characters clearly indicate Ph. uvarovi to be the basal taxon within the genus Phonochorion and to be most closely related to Polysarcus zacharovi and the Poecilimon heroicus-group.
Understanding nuptial gift size in bush-crickets: an analysis of the genus Poecilimon (Tettigoniidae: Orthoptera)
TLDR
The results support the ejaculate-protection hypothesis, and are not inconsistent with the paternal investment hypothesis, but caution is needed when using ampulla size to predict sperm number or sperm number to predict ejaculate size.
Mating Behavior and Spermatophore Characteristics in Two Closely Related Bushcricket Species of the Genus Phonochorion (Orthoptera: Phaneropterinae)
TLDR
Two closely related bushcricket species, Phonochorion uvarovi and P. artvinensis, distributed at the high altitudes of the Kaçkar Mountains, northeastern Turkey, show that they have different reproductive investments in terms of spermatophore and sperm numbers in spite of similar habitat and nutritional preferences.
Understanding the size of nuptial gifts in bush-crickets: an analysis of the ge- nus Poecilimon (Tettigoniidae: Orthoptera)
TLDR
The results support the ejaculate protection hypothesis and are not inconsistent with the paternal investment hypothesis, but caution is needed when using ampulla size to predict sperm number or sperm number to predict ejaculate size.
Orthoptera and Mantodea fauna of Kazdağı (Ida) National Park with data on the calling songs of some bush-crickets.
TLDR
The calling songs of Metrioptera arnoldi, Rhacocleis acutangula, Anadolua schwarzi, Isophya cania, and Poecilimon luschani are described here for the first time.
Larger ejaculate volumes are associated with a lower degree of polyandry across bushcricket taxa

TLDR
A positive relationship was found, across bushcricket taxa, between relative nuptial gift size and relative ejaculate mass, indicating that largernuptial gifts allow the male to overcome female resistance to accepting large ejaculates.

The ultimate function of nuptial feeding in the bushcricket Poecilimon veluchianus (Orthoptera : Tettigoniidae : Phaneropterinae)
TLDR
The increase in relative dry weight of hatched larvae was increased, indicating that there may also be a paternal investment effect of the spermatophylax, if the offspring that benefit from sperMatophylAX materials are fathered by the donating male.
Mating effort function of the spermatophore in the bushcricket Poecilimon veluchianus (Orthoptera, Phaneropteridae): support from a comparison of the mating behaviour of two subspecies
TLDR
Despite large differences in the mass of the spermatophore, its main function seems to be to ensure sperm transfer, which can be concluded from the similarity between the duration of sperm transfer and the time period necessary for sperMatophore consumption in each of the subspecies.
Biogeography of the tenebrionid beetles (Coleoptera, Tenebrionidae) on the Aegean Islands (Greece)
TLDR
This research aimed to study if a transitional character can be postulated for the tenebrionid beetle fauna of the Aegean Islands, and to identify ecological and historical factors responsible for observed patterns.
The evolution and function of the spermatophylax in bushcrickets (Orthoptera: Tettigoniidae)
TLDR
A comparative study of 43 species of bushcricket revealed a positive relationship, across taxa, between evolutionary changes in spermatophylax size and changes in ampulla size and sperm number, with male body weight controlled for.
Inheritance of body and testis size in the bushcricket Poecilimon veluchianus Ramme (Orthoptera; Tettigoniidae) examined by means of subspecies hybrids
TLDR
Whether sexually selected traits may commonly be sex-linked is considered, and the X-chromosomal (maternal) inheritance of body mass and a testis mass similar to the paternal subspecies is considered.
EAVESDROPPING AND DEFENSIVE AUDITORY MASKING IN AN AUSTRALIAN BUSHCRICKET, CAEDICIA (PHANEROPTERINAE: TETTIGONIIDAE: ORTHOPTERA)
TLDR
This work suggests means by which the calling male may be able to hear the female reply whilst producing the masking chirp, which may be considered a form of pre-copulatory acoustic mate guarding.
Song pattern recognition and an auditory time window in the female bushcricket Ancistrura nigrovittata (Orthoptera: Phaneropteridae)
TLDR
In experiments with artificial song models, the parameters necessary for eliciting a female response to a duet were analysed and the female response was shown to depend on two processes: recognition of the syllable group as belonging to a conspecific male and perception of the final syllable as a trigger.
Songs and the Function of Song Elements in Four Duetting Bushcricket Species (Ensifera, Phaneropteridae, Barbitistes)
TLDR
The structure of male songs and the timing of female replies with respect to the male songs are described for four species of the palaearctic bushcricket genus Barbitistes and a close phylogenetic relationship between B. constrictus and B. serricauda is assumed.
Insect duets: underlying mechanisms and their evolution
TLDR
The mechanisms of the duet are examined first, followed by evolution and the associated change in searching strategies of each sex, and these are compared with acoustic interactions among males in those species that exhibit male–male synchrony and alternation.
