OPISTHOSOMAL MUSCULATURE OF FEMALE ARANEUS DIADEMATUS (ARANEAE: ARGIOPIDAE)
Published online by Cambridge University Press: 31 May 2012
Abstract
The opisthosomal musculature of adult female Araneus diadematus Clerck was investigated by means of dissections. Forty-nine different muscles, each paired, were found in the opisthosoma proper. Of these muscles, 7 pairs move the opisthosoma about the pedicel, 13 pairs compress the opisthosoma, 19 pairs move the spinnerets and colulus with respect to the opisthosoma, 4 pairs dilate the anus, 3 pairs dilate the genital aperture, and 3 pairs open the book-lung spiracles.
