Description
Summary:Using scanning electron microscopy, previously overlooked cuticle modifications were revealed in the attachment points of skeletal musculature of Trigoniophthalmus simplex (Insecta, Archaeognatha, Machilidae). These findings demonstrate that SEM may serve as an indirect approach for rapidly and precisely mapping complicated abdominal musculature of Archaeognatha. The reference to Archaeognatha is especially relevant for the mapping of the abdominal muscles in insects in the sense of the presence of a hypothesized plesiomorphic sclerite composition in this group of wingless insects.
