Polyplectropus thilus species group

This group was designated by ( Yamamoto 1967) and included P. deltoides (Yamamoto) and P. thilus (Denning) . Several species originally in this group are now in the P. bredini group. Species in the group are quite homogeneous with mostly differing in the shape of the intermediate appendage, the mesoventral process of the preanal appendage, and in slight differences in the shape of the inferior appendage. The P. thilus group is characterized by the combined possession of the following traits ( Figs. 98-116):

1. Presence of an elongate, sclerotized dorsolateral process of the preanal appendage;

2. presence of a papillate lobe;

3. shape of intermediate appendage with apex turned mesally;

4. presence of microsetae interspersed throughout surface of intermediate appendage;

5. dorsolateral arm of dorsal phallic sclerite tapering subapically.
