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).
DIAGNOSIS: Female: Antennae and legs long and thin, cephalic stridulatory
apparatus absent, mesoscutellum with an upright spine, corium with a triangular cell.
Six to seven stridulatory
ridges on the mesal dorsal aspect of the chelicerae (Fig.
This approach will also be used to investigate the interspecific difference of the stridulatory
signals between S.
The noises that ants seem to make intentionally, drummings and fast stridulatory
scrapings of roughened body parts, can buzz through substrates easily.
58kx, except for sclerolepidia and stridulatory
organs which were examined at high vacuum between 454x and 7kx after 36nm of gold/palladium coating.
ducalis is based on the number of stridulatory
teeth on the maxilla.
groove of prothorax deep and emarginate.
2B, D); III with smooth, raised ridge medially, with stridulatory
granules submedially; V with prominent pale, raised surface posteromedially in adult L, and 6-10 evenly spaced short, acuminate macrosetae along posterior margin; VII finely granular laterally and medially, with pair of costate-granular ventrosubmedian and ventrolateral carinae.
Ventral surface with elongate-oval stridulatory
area formed by 25 narrowly separated ridges; ventral process well-developed, rounded, with many asperities.
bristles present on sides of carapace.
