The cerambycid genus F,ormosotoxotus is Abstract The cerambycid genus F,ormosotoxotus is revised. Fo r, n oso to:xo tus masataka1 masataka1 sp no v. is desc r ibed from Sik ki m, and F fulvopi1osus HAYAsHI, 1979 is synonymized synonymized wi th F malayanus HAYAsHI, 1977. The systemat ic posi tion of thegenus is is discussed and it is placed in the subfamily Apatophyseinae.

Introduction O n On my shor t t rip to Paris made in 2005, I found a very old specimen belonging to the genusFormosotoxotus in the collection of the Museum national d'Histoirenature11e. A fter After a careful examination, it was concluded that the specimen belonged to a species new to science. Along with description of the new species, I take this opportunity to revise revise briefly the genusFormosotoxotus and bestow some considerations on its systematic position. Taxonomic placement of the species of Formosoto:x;otus has frequently Taxonomic placement of the species of Formosoto:x;otus has frequently changed. oxotinus KANO (1933) descr ibed the first species 「oxotinus auripi1osus from Taiwan as a close relative relative of To:)cotinus reini1 HEYDEN. In the same year, MATSUSHITA (1933) described Artelida aslatica from Taiwan (the genusArtelida had been used unt il then Artelida aslatica from Taiwan (the genusArtelida had been used unt il then exclusively for for Madagascan species). (1951) placed T1oxotinus auripi1osus GRESSITT (1951) placed T1oxotinus auripi1osus in the genus To:x;otus (subgenus To:xotinus) of To:xotinus) of the Stenocorini. Simultaneously he erected a new genus Paranthophylax (in Xy1osteini) for a new species, P. sericeus(designated as the type species) (in Xy1osteini) for a new species, P. sericeus(designated as the type species) andP aslaticus, aslaticus, t ransferred to th is genus from Artel ida. Paranthophylax is current ly regarded Synonymof the genus Trypogeus as a juniO「 Synonymof the genus Trypogeus LACORDAIRE.In l960, HAYAsHI synonymized Artelida synonymized Artelida aslatlca with Toxotinus auripi1osus and established a new genus F,ormosotoxotus for lt. Since then, five more species were added to the F,ormosotoxotus for lt. Since then, five more species were added to the genus F,ormoso- t();)cetus, viz., F malayanus HAYAsHI, 1977 and F fulvopi1osus HAYAsHI, 1979, from M alaysia, F. uenoi N. 0HBAYAsHI, l 995, Malaysia, F. uenoi N. 0HBAYAsHI, l 995, f rom Kalimantan, Indonesia, F takaoi NIISATo, 1996, from North Vietnam, and F nobuoi VI vEs et N IIsATo, 2006, from Nepal.

The subfami ly Apatophysinae LAcoRDAIRE was erected by DANILEvsKY (1979) for a single genus, CHEvRo LAT, main ly based on the larval morphology (original LAcoRDAIRE's Apatophysides included also the Sou th African genusPachytt'con THOMSON and the Oriental Trypogeus whose larvae were African genusPachytt'con THOMSON and the Oriental Trypogeus whose larvae were and still are unknown). The correct spelling of the subfamily name apparently shou ld be Apatophyseinae, first used by LoBANov et a1. Apatophyseinae, first used by LoBANov et a1. (1981). So far there have been few external adult characters dist inguishing the Apatophyseinae external adult characters dist inguishing the Apatophyseinae from other subfamilies. However, the subfamily could be characterized by a combination of stridulatory file of mesonotum, mesonotum, hind wing venation and male genitalia (personal unpublished results) . Based on my study of h ind wing venat ion and male geni tal ia, I conclude that the Based on my study of h ind wing venat ion and male geni tal ia, I conclude that the genus F,ormosoto:x:otus is closely rel ated to Apatophysls, and thus it belongs to the subfami ly Apatophyseinae.

According to the original descr ipt ions, body lengths of the former same local it y. According to the original descr ipt ions, body lengths of the former species are 10mm (the holotype male) and 15 mm (a paratype female), and that of the are 10mm (the holotype male) and 15 mm (a paratype female), and that of the latter species are 17 mm (holot ype male) and 21 mm (a parat ype female). In 1985 species are 17 mm (holot ype male) and 21 mm (a parat ype female). In 1985 HAYASHI & & VILLIERS re-described these two species, and distinguished them by the following key: 1. Body brownish red, covered with fulvous hairs; frons separated from clypeus by 1. Body brownish red, covered with fulvous hairs; frons separated from clypeus by an arcuate groove; antennae shorter than body in male, gena sh o rter than eye- diameter; elytra about twice as long as basal width, disc rather simple.10-15 diameter; elytra about twice as long as basal width, disc rather simple.10-15 mm F malayanus - Body -Body dark reddish brown, covered with pale fulvous hairs; frons separated from clypeus by a straight transverse groove; antennae fairly longer than body in clypeus by a straight transverse groove; antennae fairly longer than body in male, gena as long as eye-diameter; elytra a little longer than twice as long as the gena as long as eye-diameter; elytra a little longer than twice as long as the basal F width disc with four disca1 costae. 17-21 mm F f u lv o p i i o s u s My examination of a ser ies of specimens col lected on the Cameron My examination of a ser ies of specimens col lected on the Cameron Highlands showed showed that the differences between the two species described by HAYASHI are intra- specific specific variations. The difference of antennal length and elytra1 proport ion indicated in is the key is not a specific feature but a sexual difference, because the holotype of Flormosoto:xlotus malayanus described as male in his original descr iption was a Flormosoto:xlotus malayanus described as male in his original descr iption was a female. Other differential character istics also depend on the sexual dimorphism, or on the difference of body size. Body lengths of the specimens examined are quite variable difference of body size. Body lengths of the specimens examined are quite variable as 17.1 follows: 6.8, l l.2, 11.5, l t.9, 12.0, 12.7, 16.0, 17.1 mm in male and 7.5, 8.6, 9. 9 (holotype of F malayanus) , 11.0, 11.2 mm in female, respectively. Disca1 costae of (holotype of F malayanus) , 11.0, 11.2 mm in female, respectively. Disca1 costae of the elytra are distinct in large specimens, and the condition of fronto-clypea1 suture elytra are distinct in large specimens, and the condition of fronto-clypea1 suture differs with with individuals. As a result, F fulvopi1osus is here placed as a junior synonym of F m alayan malayan us. Sp e c i me ns ex a m i n e d. 1早 (Holotype), Tana Rata, Malaysia, 22- I - 1976, Y. KIYoYAMAleg.
