The genus Ectadia is an East Asian genus of the tribe Elimaeini (Phaneropterinae) and is known for the complex stridulatory
files of its members.
A new species of Pseudotettigonia Zeuner (Orthoptera: Tettigoniidae) with an intact stridulatory
field and reexamination of the subfamily Pseudotettigoniinae.
In terrestrial oniscoid isopods, presumable stridulatory
apparatus has been reported.
This is the first description of stridulatory
structures, acoustic signals and associated behaviors in D.
A simple leg-carapace stridulatory
mechanism (Figs 5-7) and bulbus morphology suggest an affinity to Pseudicius Simon, 1885 (cinctus--group sensu Proszynski 2013).
1c,e,g,h); male stridulatory
organ not protruding beyond the level of posterior tegminal margin; Cerci of male much thinner than second antennal segment very slightly and gradually widened and barely flattened outer margin (Fig.
Copulatory mechanism in Holocnemus pluchei and Pholcus opilionoides, with notes on male cheliceral apophyses and stridulatory
organs in Pholcidae (Araneae).
In addition, the sexual role of the stridulatory
setae of Acanthoscurria suina has no relevance in a sexual context; it may be involved in a defensive function (Perez-Miles et al.
DIAGNOSIS: Female: Antennae and legs long and thin, cephalic stridulatory
apparatus absent, mesoscutellum with an upright spine, corium with a triangular cell.
Males with stridulatory
apparatus composed of a field of excavations on dorsal surface of protarsomere 2 (file) (Fig.
Diagnosis: Body usually slender; pronotum usually with median and lateral carinae; tegmina and wings fully developed; spurious median vein of tegmina usually absent; prosternal process usually absent; femoro-tegminal stridulatory
mechanism absent; hind femur without row of modified peg like structures at lower edge of inner surface; male with epiphallus bridge shaped having ancorae and lophi, aedeagus with basal apical valves connected by flexure.
Six to seven stridulatory
ridges on the mesal dorsal aspect of the chelicerae (Fig.
