Pterotiltus campoensis sp. nov. phallic structure. A. Endophallus and part of ectophallus after removal of the outer ectophallic sheath. The LHS cingular ramus and most of the LHS cingular apodeme has been removed to expose the endophallus. The basal endophallic valves give rise to paired narrow flexures that lead to the ventral aedeagal valves; B. Endophallus after removal of the ectophallic valvular plate and cingulum. The endophallic processes are short and terminate in spatulate endings that are appressed to ventral aedeagal sclerites, which form the greater part of the ventral aedeagal valve; C. More magnified view (scale does not apply) of the junction between the RHS endophallic process and the ventral aedeagal sclerites, viewed from the midline. The precise relations of the terminal sclerites and the membrane of the spermatophore sac are presently unclear. Scale bar: 1 mm.
