Pamphilius inanitus

Shinohara, Akihiko, Kramp, Katja & Taeger, Andreas, 2022, The Pamphiliinae of the Russian Far East and Korea (Hymenoptera, Pamphiliidae), Zootaxa 5167 (1), pp. 1-251 : 74

Pamphilius inanitus group

The members of this species group are characterized as follows: upper part of head glabrous; facial crest in male very strongly swollen, very bluntly carinate; antennal flagellomere 1 0.9–1.4 × length of flagellomere 2; right mandible tridentate but incision between middle and apical teeth very shallow or bidentate with only basal shoulder to apical tooth; left mandible tridentate with low middle tooth; wings hyaline; forewing with cell C pilose; femora entirely pale. Ovipositor sheath appendage very small, pilose. Male genitalia ( Fig. 80f, g ): proximal ventral arm of gonostipes normal; apiceps short and narrow; valviceps in lateral view rather short, apex directed above, ventral margin more or less rounded, without conspicuous dorsoapical process.

Only two closely related species are known from the Palaearctic region ( Shinohara 2002b), of which one, P. hilaris , occurs in the Russian Far East and Korea.

Six sequences of two species were treated in the COI analysis and one specimen of one species in the NaK analysis. In the COI analysis ( Fig. 143 ), the P. inanitus group was retrieved as monophyletic with 100% UFBoot support and had a sister relationship (with 91% UFBoot support) with the clade composed of the P. brevicornis and P. gyllenhali subgroups of the P. histrio group. This clade ( P. inanitus group + P. brevicornis and P. gyllenhali subgroups of P. histrio group) was the sister group of the P. betulae subgroup of the P. histrio group but with low UFBoot value of 84%. In other words, the P. inanitus group was placed within the P. histrio group. In the NaK analysis ( Fig. 157 ), the P. inanitus group was recovered as the sister of the clade represented by the P. histrio and P. sulphureipes groups with 100% UFBoot support. The affinity of the P. inanitus group is still uncertain, but it appears closer to the P. histrio and P. sulphureipes groups, rather than to the P. sylvaticus group as suggested by Shinohara (2002b).

The larvae of this species group feed on Rosaceae (Rosa) .
