First records of the spider wasps Ctenocerus Dahlbom and Paraclavelia Haupt from Asia, with discussions on the systematics of Ctenocerinae (Hymenoptera: Pompilidae)

We describe two new species of Ctenocerinae (Pompilidae) from Asia, i.e., Ctenocerus srilankae Shimizu sp. nov. Sri Lanka and Paraclavelia arabiae Oman. These represent the first records Dahlbom, 1845 Haupt, 1930 in Asia. Two combinations a synonymy are proposed: fasciatus (Smith, 1851) (= Micropteryx fasciata Smith, 1851); decipiens (Arnold, 1932) Clavelia Arnold, 1932); Euclavelia 1932). discuss difficulty systematics at generic level. The head pronotal structures presumably specialized for preying on trapdoor spiders. considered to have evolved independently other unrelated parasitoid Pompilidae that been confirmed or proposed prey also biogeographical distribution these genera.
