Group laricis

Description follows Prous et al, 2017.  

Species within this group have the following characteristics. The sawsheath is short with shallow invagination and with the cerci protruding beyond the apex.  The penis valves have a short valvispina without a posteriorly contricted hump. The anterior protibial spur has evenly distributed hairs but lacks any dense velum patch, and the body is mostly black.  

The larvae feed on Larix spp. (larches).
