- <p><b><i>Gynapteromyia heteroptera</i> (Mamaev & Spungis, 1980) comb. nov.</b></p><p>Figs 2, 4E–F</p><p><i>Chastomera heteroptera</i> —Mamaev & Spungis in Mohrig <i>et al</i>. 1980: 149, fig. 1; Spungis 1985: 41, fig. 1. <i>Haplusia heteroptera</i> — Gagné 1978: 518; Jaschhof & Jaschhof 2013: 61.</p><p>This species, originally described in Mohrig <i>et al</i>. (1980) and subsequently by Spungis (1985) and Jaschhof & Jaschhof (2013), is known from a very few specimens found in Lithuania, Latvia, and Sweden. In addition to the only specimen previously known from Sweden, a male from Uppland (Jaschhof & Jaschhof 2013), four males are reported here from Öland.</p><p><b>Diagnosis.</b> This is the only <i>Gynapteromyia</i> known to have an elongate-trapezoid tegmen without protruding corners apically, gonocoxal apodemes with very short anterior processes, and no ejaculatory apodeme (Mohrig <i>et al</i>. 1980: fig. 1g; Spungis 1985: fig. 2.3). Female wings may be everything from normally developed to strongly reduced (Mohrig <i>et al</i>. 1980: fig. 1a). Female microptery is known also from <i>G. carpatica</i>, a species with singlesegmented palpi (compared with 2–3 palpal segments in <i>G. heteroptera</i>), and might well occur in <i>Gynapteromyia</i> species whose females have not yet been found.</p><p><b>Male characters not mentioned or described otherwise in previous literature. Head.</b> Genal setae 0–1. Palpus with either 2 or 3 segments (Fig. 4E–F), sensory hairs on first and second segments. <b>Wing.</b> Vei n b t v unsetose. Setae confined to apical portion of membrane. Length of CuA varying, usually fading out before wing margin. <b>Legs.</b> Distitarsi with sparse setae, conspicuously dense microtrichia.</p><p><b>Material examined.</b> Sweden: 2 males (CEC00135−00136), Öland, Borgholm, Rönnerum-Abbantorp Nature Reserve, mixed deciduous forest with predominantly hornbeam, 17 June–15 July 2015, Malaise trap, M. & C. Jaschhof (in NHRS); 2 males (CEC00137−00138), Borgholm, Lindreservatet Nature Reserve, mixed deciduous forest, 11 June–21 July 2015, Malaise trap, M. & C. Jaschhof (in SDEI).</p>
