There is considerable variation in sculpture of the upper head, mesonotum and 1 st tergite, which may be clearly stronger denser than in the holotype. The metallic blue colour of the head and thorax sometimes turns into coppery green or purple, even if the most common colour is metallic blue. The wings are darkened from apical third to apical two thirds in the females. Females 13-16 mm, males 12-14 mm. Distribution. China (Taiwan). Remarks. This species is similar to S. leucotarsis, but differs from the latter by the following: middle fovea broad and deep; cell C dark brown; inner orbit of female shiny; mesoscutellum strongly elevated, distinctly higher than top of scutum; the apical half of forewing strongly infuscated; the basal half of hind tibia and metabasitarsus entirely yellow, the apex of hind tibia slightly enlarged, 2.2 × as broad as the base of tibia, metabasitarsus 4.5 × as long as broad; each femur, tibia and tarsus of male orange brown. In S. leucotarsis: middle fovea small; cell C brown; inner orbit of female sparsely punctured; mesoscutellum roundly elevated, as high as scutum; the apical 1 / 4 of forewing infuscated; the basal 1 / 3 of hind tibia white, metabasitarsus entirely bluish purple, the apex of hind tibia distinctly enlarged, 2.8 × as broad as the base of tibia in length, metabasitarsus 3.6 × as long as broad; the apical 2 / 3 of fore and middle tibiae blackish brown, apical 2 / 3 of hind tibia and metabasitarsus bluish purple; in male, femora, tibiae and tarsi not orange brown, but similar to the female.Published as part of Niu, Gengyun, Wei, Meicai & Taeger, Andreas, 2012, Revision of the Siobla metallica group (Hymenoptera: Tenthredinidae), pp. 1-49 in Zootaxa 3196 on page 8, DOI: 10.5281/zenodo.28010

Colour and structure similar to female except as follows: Pale line along posterior margin of pronotum extremely narrow; tegula entirely black; most of trochanter black, with broad apical margin whitish; trochantellus largely black; hind femur black except for wide stripe on anterior surface pale brown; antenna with antennomere 2 entirely black and antennomeres 3 to 5 marked with black ventrally; malar space 0.2 × diameter of lateral ocellus; shortest distance between eyes 0.8 × as long as height of eye; temple about 0.6 × eye length in dorsal view (Fig. 11 b); hairs on dorsum of head, dorsum of mesoscutellum, and pleuron 1.3 × as long as diameter of median ocellus, hairs on pleuron distinctly curved. Subgenital plate longer than broad, apical margin rounded (Fig. 11 d); valviceps narrow (Fig. 8 r); gonoforcep as Fig. 8 i. Etymology. This species is named in honour of the late K. Takeuchi, who made a pioneering contribution to the sawfly systematics in East Asia. Distribution. Japan (Hokkaido, Honshu, Kyushu). Holotype (Figs 3 c, 5 s): ♀, Ashiu-enshurin, Miyama-cho, Kyoto, Honshu, 11. VI. 1989, K. Mizuno, NSMT-I- HYM 65836, genitalia slide N 20130906 B (NSMT). Paratypes: 165 specimens (57 ♀ and 108 ♂, see Appendix). Variation. The length varies from 11.0 to 15.5 mm in the female and 9.5 to 13.0 mm in the male. The colouration of the antenna shows large variation, but the apical four or five antennomeres are always black and the scape and pedicel are usually partly or entirely black in both sexes. The other antennomeres are usually mostly or entirely brown, though the antenna is almost entirely black in very dark specimens. In the female, the mesoscutellum often has an obscure brownish spot medially, the hind trochanter is sometimes marked with black ventrally, and the abdominal terga 2 and 3 are often marked with black. In the male, the pale line along the posterior margin of the pronotum may be missing, the hind trochanter and trochantellus are always marked with black, the abdominal terga 2 (except for the narrow anterior margin) and 3 are always yellow brown, and the tergum 4 is often yellow brown at base. The ranges of some ratio variations are given in the key. Remarks. Siobla takeuchii is a member of the S. formosana group defined by Niu & Wei (2010), though the males could run to the S. sturmii group or to the S. ferox group in the key (Niu & Wei 2010). The new species closely resembles S. hirasana Takeuchi, 1929, belonging to the S. ferox group. In the female, S. takeuchii has the anterior margin of the clypeus weakly protruding (Fig. 11 c), the labrum dark brown basally, the posterior margin of the pronotum, tegula, and mesoscutellum usually entirely black (mesoscutellum rarely with small obscure spot medially), the metabasitarsus equal in length to the following three tarsomeres combined, hind trochanter sometimes marked with black, and the sawsheath black, except at apex. The female of S. hirasana has the anterior margin of the clypeus nearly truncate (Fig. 11 g), the labrum whitish basally, the broad posterior margin of pronotum, tegula, and mesoscutellum always mostly yellowish brown, the hind trochanter never marked with black, and the sawsheath entirely pale brown. In the male of S. takeuchii, the tegula and mesoscutellum are entirely black, the hind trochanter and trochantellus are usually largely blackish brown or black, and the subgenital plate is narrowly rounded at apex (Fig. 11 d), whereas in S. hirasana the tegula and mesoscutellum are largely yellowish brown, the hind trochanter and trochantellus are usually entirely whitish brown, rarely partly marked with blackish brown, and the subgenital plate is broadly rounded at apex (Fig. 11 h). The two species also differ in the shape of the head in dorsal view (Fig. 11 a–b, e–f). Takeuchi’s (1919 b) description of “ Siobla ruficornis Cameron?” was based on an unknown number of specimens from Yoshino, Nara prefecture, and two male specimens from “Shinano” (=Nagano prefecture). Two pairs of S. takeuchii collected in Yoshino in 1916 and kept in Takeuchi’s collection in OPU agree with the description of “ Siobla ruficornis Cameron?” by Takeuchi (1919 b) and should belong to his original material. Takeuchi (1919 b, p. 14) noted that the two male specimens from “Shinano” differed from the Yoshino specimens in that the antenna was yellowish brown except for the basal three antennomeres and in that the yellowish brown parts of the body were more reddish. We were not able to locate those two males in Takeuchi’s collection but they probably belong to S. sturmii because of the colour pattern of the antenna and the hind femur. The male specimen of “ S. ferox ” shown by Esaki et al. (1939) in their figure 592 2 in plate 152 has apically black antenna and entirely black dorsum of the thorax. This specimen was not available for the present study but it most probably belongs to S. takeuchii, because S. ferox has the apex of the antenna usually brown, though sometimes darkened, and has the dorsum of the thorax and the abdominal tergum 1 largely marked with pale brown. Togashi’s (1955) figure of the penis valve of “ S. ferox ” agrees most closely with that of S. takeuchii. Some specimens cited as S. ferox by Naito (1982) and Naito et al. (2004) and those listed under S. sturmii and Siobla sp. D by Katayama (2004) also belong to the present new species (see Appendix).Published as part of Shinohara, Akihiko, Wei, Meicai & Niu, Gengyun, 2013, Revision of Siobla (Hymenoptera, Tenthredinidae) from Japan, pp. 1-40 in Zootaxa 3746 (1) on pages 22-26, DOI: 10.11646/zootaxa.3746.1.1, http://zenodo.org/record/28529
