Diagnosis.
Males can be easily distinguished by the truncated tegular spine (
Fig. 415
), the membranous posterior margin of the embolic base (
Fig. 413
) and the pronounced RTA with apical modification (
Fig. 414
). The female is recognized by the strongly elongated apical part of the spermathecae provided with 15 unequal coils.
Etymology.
The specific epithet is derived from Latin (stem
convolutes
= past participle of
convolvare
= to roll up, to entwine).
