Pamphilius basilaris group

The members of this species group are characterized as follows: antennal flagellomere 1 1.0–2.2 × length of flagellomere 2; right mandible tridentate with incision between middle and apical teeth much deeper than incision between basal and middle teeth; left mandible bidentate with middle tooth missing (figs 8C, 8D in Shinohara & Wei 2012); wings strongly infuscate in basal 3/2 and clear hyaline in apical 1/3 (figs 8A, 8F in Shinohara & Wei 2012); forewing with cell C glabrous, 1st abscissa of vein Rs very long and cell 1M small and short; femora entirely pale. Subgenital plate in male with large setose appendage. Ovipositor sheath appendage very large, pilose. Male genitalia: proximal ventral arm of gonostipes normal; apiceps simple, narrow; valviceps in lateral view rather short, apex directed upwards, ventral margin rounded, without conspicuous dorsoapical process.

Two species are known, P. basilaris Shinohara, 1982 from Japan and P. lizejiani Shinohara, 2012 (in: Shinohara & Wei 2012) from China. This species group has not been found in the Russian Far East and Korea, though it is likely to occur particularly in Korea. For the COI and NaK analyses, two sequences each of P. basilaris were used and they were retrieved as monophyletic with 100% UFBoot support in both analyses. In the COI tree ( Fig. 141 ), P. basilaris was the sister group of the Nearctic P. ocreatus ( P. sylvaticus group) and this pair was the sister group of Onycholyda but these relationships had low UFBoot support (75% and 64%, respectively). In the NaK tree ( Fig. 155 ), the P. basilaris group was retrieved as the sister of the large clade represented by the speciose P. vafer and P. sylvaticus groups but this relationship was supported only by 87% UFBoot value. The affinity of this species group within Pamphilius or Pamphiliini is still unclear.

Among the Pamphiliidae , the members of this species group are unique in their association with Juglandaceae ( Juglans and Platycarya ) (Shinohara et al. 2012).
