Treatment

Subspecies trichopse ( Strand, 1914 )

Synonymy (following Ebmer 1988: 649)

Distribution

This subspecies is distributed from East Himalaya, China ( Ebmer 1978a: 207; 2006: 569), Mongolia ( Ebmer 1982: 219; 2005: 378), Japan (Hokkaido: Usui et al. 1976: 228; Izu: Takahashi & Sakagami 1993: 271, 275; Honshu: Haneda 1990: 8; Okinawa: Azuma & Kinjo 1987: 314), North Korea ( Ebmer 1978b: 315), South Korea ( Murao 2017), south of Russian Far East (Primorsk Terr.: Ebmer 1996: 285, 2006: 569; Amur Prov.: Pesenko 2007b: 113), Taiwan and south to Malaysia ( Fig. 11 View Fig ). It is not the purpose of this paper to discuss the status and diagnosis of this subspecies, as little material is available for examination and no fresh material was available for DNA study. The subspecies is distinguished from the subspecies villosulum mainly by shorter and more rounded head and broader eyes. We have examined and photographed the heads of old specimens from the typical locality in Taiwan and preserved in the MNHUB and compared them with the heads of L. villosulum villosulum and L. medinai ( Fig. 12 View Fig ). The punctation and genitalia of males are similar to those of L. villosulum .
