Polynema

Triapitsyn, Serguei V., 2021, Taxonomic review of Polynema (Hymenoptera: Mymaridae) in Australia and New Zealand, with descriptions of eight new species, Zootaxa 4915 (2), pp. 151-200 : 153

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.
