Revision of Australasian Trissolcus species (Hymenoptera : Scelionidae)

Abstract

The species of Trissolcus Ashmead of the Australasian region (including New Guinea, the Bismark Archipelago and the Solomon Islands to Tahiti and New Zealand) are revised. Trissolcus ancon, T. arctatus, T. cirrosus, T. maori, T. personatus, T. setifer, T. sipioides and T. strigis are described as new. Trissolcus eetion (Dodd), T. egeria (Dodd), T. ephyra (Dodd), T. euander (Dodd), T. flaviscapus Dodd, T. latisulcus (Crawford), T. mitsukurii (Ashmead), T. oedipus (Dodd), T. oeneus (Dodd), T. oenone (Dodd), T. ogyges (Dodd) and T. painei (Ferrière) are redescribed. Trissolcus basalis (Wollaston) is a widely introduced Afrotropical species found throughout this region. The following new synonymies are proposed: Trissolcus coriaceus Dodd, 1915 = T. egeria (Dodd), 1914; T. oecleus (Dodd), 1913, T. darwinensis (Dodd), 1914, T. erigone (Dodd), 1914, T. banksi (Gahan), 1921 and T. priapus (Nixon), 1938 = T. latisulcus (Crawford), 1913; T. oecleoides (Dodd), 1914 = T. mitsukurii (Ashmead), 1904; T. obliteratus (Dodd), 1914, T. otho (Dodd), 1914, T. biproruli (Girault), 19262, and T. wilsoni (Dodd), 1930 = T. oenone (Dodd), 1913; T. oreas (Dodd), 1913, T. orontes (Dodd), 1914, T. atriscapus (Girault), 1926a and T. beenleighi (Girault), 1932 = T. ogyges (Dodd), 1913.
