Diagnosis: Aphelinoidea shawanica is very similar to A. (Aphelinoidea) subexserta Nowicki except for the marginal vein of the fore wing being apparently relatively (about 1.5×) thicker in the latter species ( Fig. 80) than in A. shawanica ( Fig. 73). The hypopygium of A. shawanica extends to 0.7–0.8× length of the gaster ( Figs 70, 71). The examined holotype and paratypes of this species are particularly similar (e.g. the fore wing, Fig. 73) to the smaller female paratype “a” of A. subexserta from Nagy Hortobágy in the Hungarian Puszta (Hortobágy National Park, W of Debrecen, Hajdú-Bihar County), Hungary (Nowicki 1940) ( Figs 85–87). In both A. shawanica and A. subexserta the marginal setae on the fore wing are about the same length, and chaetotaxy and the basal infuscation on the disc are very similar, but the ovipositor, which occupies almost the entire length of the gaster, is a little but clearly exserted beyond its apex in A. shawanica ( Figs 70, 71). The antenna of A. shawanica female ( Fig. 69) has the clava somewhat collapsed in the examined type specimens so its width could not be measured precisely. Also see the measurements relevant to its recognition ( Table 1). Thus, the existence of apparent intermediate forms between these two species prompt further­investigation­of­their­likely­conspecificity.

Aphelinoidea yousufi Khan & Anis from India ( Khan & Anis 2016) seems to be very similar to A. shawanica , particularly the venation of their fore wings, except for a relatively shorter ovipositor which is about 1.5× length of the metatibia in A. yousufi ( Khan & Anis 2016) but at least about 2.1× in A. shawanica .

Distribution: China (Xinjiang) ( Hu & Lin 2005), and also possibly Kyrgyzstan (see Comments below).

Hosts: Unknown.

Comments: The following female may belong to A. shawanica , although its marginal vein is more like in typical A. subexserta : Kyrgyzstan, Jalal-Abad, Chandalash­River,­ 41°44'19"N­ 70°52'22"E,­1630­m,­ 20.vi.1999,­C.H.­Dietrich­[UCRC].­ Its ovipositor is 2.5× length of the metatibia, occupies the entire length of the gaster, and is exserted a little, but yet quite notably, beyond its apex like in some A. shawanica .
