Taxonomic review of Polynema (Hymenoptera: Mymaridae) in Australia and New Zealand, with descriptions of eight new species Author Triapitsyn, Serguei V. text Zootaxa 2021 2021-01-21 4915 2 151 200 journal article 8662 10.11646/zootaxa.4915.2.1 604b1288-103e-4bb8-bd90-6f77b653dada 1175-5326 4454213 6E0C3BA7-7C8B-4D80-AFE4-07AEC6DEC71C Subgenus Polynema ( Dorypolynema Hayat & Anis, 1999 ) Remarks . Within Polynema sensu lato , the anteriorly swollen petiole is a feature that is not restricted only to species of P. ( Dorypolynema ). It also occurs, for example, in a native species of P. ( Polynema ) from Hawaii Island, Hawaiian Islands (specimens in UCRC). Swollen and wide, sometimes somewhat flattened petioles are usually associated with long ovipositors, as in P. ( Doriclytus ) vitripenne (Foerster) ( Triapitsyn & Fidalgo 2006 ) , P. ( Dorypolynema ) spp. ( Triapitsyn & Aquino 2010 ), and Kalopolynema spp. ( Triapitsyn & Berezovskiy 2002b ), but not always—in one Hawaiian species of P. ( Polynema ) with a swollen petiole (specimens in UCRC) the ovipositor is short. A key to both sexes of the species of P. ( Dorypolynema ) in the world is provided below to facilitate their recognition, which is updated from Triapitsyn & Aquino (2010) . Males of an undescribed P. ( Dorypolynema ) species from Taipei City, Taiwan , of which only one poorly mounted female specimen on a slide is available ( Triapitsyn 2018a , p. 160), are unknown. Excluded from the key is another undescribed species of P. ( Dorypolynema ) from Madagascar , mentioned by Triapitsyn & Aquino (2010 , p. 63), which will be dealt with separately. Two species are treated following the key to species, P. ( Dorypolynema ) mendeli , the only species of P . ( Dorypolynema ) known from Australia , and P . ( Dorypolynema ) mboroense (Risbec) comb. n. from Acmopolynema Ogloblin , from Africa.
