Fo r, n oso to:xo tus masataka1 sp no v. is desc r ibed fromSik ki m, and F fulvopi1osus HAYAsHI, 1979 is synonymized wi th F malayanus HAYAsHI, 1977. The systemat ic posi tion of thegenus is discussed and it is placed in the subfamily Apatophyseinae. Introduction On my shor t t rip to Paris made in 2005, I found a very old specimen belonging to thegenusFormosotoxotusin thecollectionof theMuseumnationald'Histoirenature11e. After acareful examination, it wasconcludedthat thespecimenbelongedtoaspecies new to science. Alongwithdescriptionofthenewspecies,I takethisopportunity to revisebriefly thegenusFormosotoxotusandbestowsomeconsiderationson itssystematic position. Tax onomic placement of the species of Formosoto:x;otus has frequently changed. KANO(1933) descr ibed the first speciesoxotinusauripi1osusfromTaiwanasaclose「 relativeof To:)cotinus reini1HEYDEN. In thesameyear, MATSUSHITA (1933) described Ar tel id a aslatica from Taiwan (the genusArtelida had been used unt il then exclusively for Madagascan species). GRESSITT (1951) placed T1oxotinus auripi1osus in the genus To:x;otus (subgenus To:xotinus) o fh te Stenocorini. Simultaneously he erected a new genus Paranthophylax (inXy1osteini) foranewspecies,P.sericeus(designatedasthetypespecies)andP asla ticus , tra nsferred to this genus fromArtelida. Paranthophylax is currently regarded .ERIADROC AL suegopyr as a juniO「 InTl960, HAYAsHI sune g eh t fomynon Sy sy n ony m ized Artelida aslatlca with Toxotinus auripi1osus and established a new genus F, ormo so tox ot us fo r lt. Since then, five more species were added to the genus F,ormoso- t();)cetus, viz., Fmalayanus HAYAsHI,1977 and F fulvopi1osus HAYAsHI,1979, from Malaysia, F. uenoi N. 0HBAYAsHI, l 995, f rom Kalimantan, Indonesia, F takaoi NIISATo, 1996, from North Vietnam, and Fnobuoi VI vEs et N IIsATo, 2006, from Nepal. Up to n ow , all the authors regarded those species as members of the subfamily RevisionoftheGenus.Formosotoxot11s 195 Lepturinae except JENIS (2001) who illustrated an unidentified Malayan species of F,or mo so to:foe t u s an d placed it, without proper explanation, in the Apatophyseinae, together withmany Madagascanspecies, theAfricanDorcasomusSERvILLEandCapo- te;xotus rugosus TIPPMANN, and the Or iental genera Prota-x;is GAHAN and Trypogeus LA coRDAIRE. The subfami ly Apatophysinae LAcoRDAIRE was erected by DA N ILEvsKY (1979) for a single genus, Apatophysis CHEvRo LAT, main ly based on the larval morphology (original LAcoRDAIRE's Apatophysides included also the Sou th AfricangenusPachytt'conTHOMSONandtheOreintalTrypogeuswhoselarvaewereand still are unknown). The correct spelling of the subfamily name apparently shou ld be Apatophyseinae, first used by LoBANov et a1. (1981). So far there have been few external adult characters dist inguishing the Apatophyseinae from other subfamilies. However, the subfamily could be characterized by a combination of stridulatory file of me sonotum , hind wing venation and male genitalia (personal unpublished results) . Ba se d on m yst u dy of h ind wing venat ion and male geni tal ia, I conclude that the genus F, o r mo soto:x:otus is closely rel ated to Apatophysls, and thus it belongs to the subfami ly Apatophyseinae. Th is s h o rt pap er is dedicated to the memory of the late Prof. Dr. Masataka SAT0, who was one of th e most prominent Japanese coleopterist, and also had been my closest sen io r like a brother since fifty years ago.
