Abstract

Buprestis (Akiyamaia) intercostata sp. n. is described from Chayu, south-eastern Tibet. It is characterized by the presence of three additional longitudinal carinae inserted between the elevated suture and the three normal costae commonly found on each elytron of the previously known species of Akiyamaia.

Introduction

A male specimen of Buprestis subgenus Akiyamaia was unexpectedly collected by the junior author from a subalpine forest in Chayu area, south-eastern Tibet, belonging to an undescribed species. Considering that nearly all species of the subgenus Akiyamaia are very rare in nature and additional specimens are unlikely to be available in the near future, the authors decided to describe this new species. The subgenus Akiyamaia Kurosawa, 1988 (type species: Buprestis mirabilis Kurosawa, 1969) was originally established as one of the four subgenera of the genus Cypriacis Casey, 1909 (type species: Anchylocheira lauta LeConte, 1854 = Linnaeus, 1767) (sensu Kurosawa 1988). Cypriacis was established originally by Casey (1909) as one of the three subgenera of the genus Buprestis Linnaeus, 1758 (type species: Linnaeus, 1758) for classifying the North American species; it was upgraded to generic rank by Richter (1952) who established two more subgenera for the Palaearctic species of Buprestis. Kurosawa (1988) rearranged the generic and subgeneric classifications of the genus Buprestis and its allies classified by him as the Buprestis generic group, which were historically included by Obenberger (1941) in the genus Buprestis (sensu Obenberger 1941) but were recently accepted by Bellamy (2003) as the subtribe Buprestina of the tribe Buprestini after the removal of Neobuprestis Kerremans, 1903 (type species: Strigoptera australis Blackburn, 1891 = peroni Castelnau & Gory, 1838). The genera Neobuprestis (with Balthasarella Obenberger, 1958 recently revised by Levey & Bellamy, 2013 as its subgenus) and Zulubuprestis Bellamy, 1991 (type species: Zulubuprestis reliquia Bellamy, 1991) were partly or totally considered as members of Buprestini (Cobos 1974, Bellamy 1986, 1991) or the Buprestis generic group (Kurosawa 1988, Bellamy 1994); it was subsequently suggested by Volkovitsh (2001) that they constituted a separate generic group of tribal level, based upon a comparative morphological study of antennal structures using scanning electron microscopy; Levey & Bellamy (2013) described the genus Burnsiellus which belongs to the Buprestinae and may be relatively closely related to the Aglaostola branch of the Buprestinae, pointed out the similarity in the exposed anteclypeus between the Epistomentini, Zulubuprestis, Buprestis and its related genera, and did not think it is possible to draw any firm conclusions regarding the relationship of Neobuprestis to the Epistomentini and Buprestis and its related genera without a thorough cladistic analysis of the subfamily Buprestinae as a whole. Hołyński (1993) regarded Buprestina to be monogeneric subtribe containing a single genus Buprestis with a number of subgenera including

Accepted by B. Levey: 12 Jun. 2015; published: 28 Aug. 2015 389 , while Neobuprestis was transferred to Polycestina which in turn was treated as a member of Buprestini. Volkovitsh’s (2001) research supports Buprestis, Eutythyrea, and Yamina to be closely related. These opinions except those by Hołyński (1993) were accepted by Bellamy (2003, 2008, 2009). Currently Buprestina (sensu Bellamy 2008, 2009) contains the following genus-group taxa (synonyms omitted): Buprestis Linnaeus 1758 (type species: Buprestis octoguttata Linnaeus 1758) with subgenera Buprestis, Ancylocheira Eschscholtz 1829 (type species: Buprestis rustica Linnaeus 1758), Yamina Kerremans 1903 (type species: Buprestis sanguinea Fabricius 1798), Cypriacis, Stereosa Casey 1909 (type species: Buprestis decora Fabricius 1775), Orthocheira Richter 1952 (type species: Ancylocheira salomonii Thomson 1878), Pseudyamina Richter 1952 (type species: Ancylocheira variegata Klug 1829), Akiyamaia, Nelsonocheira Kurosawa 1988 (type species: Fabricius, 1787), Himalobuprestis Kurosawa 1988 (type species: Buprestis costipennis Fairmaire, 1891), and Knulliobuprestis Kurosawa 1988 (type species: Buprestis rufipes Olivier 1790); Eurythyrea Dejean, 1833 (type species: Buprestis austriaca Linnaeus 1758). The generic and subgeneric classification of Buprestina is however still controversial. Kurosawa (1988) recognized four genera: Buprestis, Cypriacis, Eurythyrea and Yamina; he also gave a detailed subgeneric classification for these genera and established three new subgenera, Nelsonocheira, Akiyamaia and Himalobuprestis under Cypriacis. This classification was generally accepted in Akiyama & Ohmomo’s (2000) and Bellamy’s (2003) books, but was not completely in agreement with Kubáň (2006), Hattori & Tanaka (2007) and Bellamy (2008). Hattori & Tanaka (2007) raised Akiyamaia from Cypriacis to full generic rank and regarded Himalobuprestis as a subgenus of Akiyamaia. Kubáň (2006) and Bellamy (2008), however, treated Cypriacis, Akiyamaia and Yamina as subgenera of Buprestis and left only two valid genera in Buprestina. In a recently published book on the Buprestidae fauna of Japan, Ohmomo & Fukutomi (2013) also treated Cypriacis as a subgenus of Buprestis. Kurosawa’s (1988) definition of Cypriacis is different from that made by Casey (1909), Obenberger (1941) and Richter (1952), with different characters employed. According to Kurosawa (1988), Cypriacis (sensu Kurosawa 1988) is distinguished from Buprestis (sensu Kurosawa 1988) only by the “pronotum rounded and swollen at the sides” and the pronotum “with more or less distinct longitudinal median groove or impression” but not with “a trace of longitudinal median carina”, it was divided into four subgenera: 1) Cypriacis, characterized by the costate elytra and the pronotum without distinct lateral depressions, distributed in the Palaearctic, North and Central Americas; 2) Nelsonocheira, characterized by the striated elytra, distributed in North and Central Americas; 3) Himalobuprestis, characterized by the costate elytra, the pronotum with distinct lateral depressions, and the sulcate abdominal ventrite between the metacoxae, distributed in the Himalayas; 4) Akiyamaia, characterized by the costate elytra, the pronotum with distinct lateral depressions, and the convex or flattened abdominal ventrite between the metacoxae, distributed in South China (Taiwan and Yunnan). The following characters historically used by some authors for defining Cypriacis were not accepted by Kurosawa (1988): elytra with costae or carinae instead of striae (Casey 1909), and scutellum slender (Richter 1952, Bílý 1982). However, the pronotal characters used by Kurosawa (1988) to distinquish between Cypriacis and Buprestis seems not to be supported by recent discoveries: Hattori & Tanaka (2007) described Akiyamaia samanthae from North Myanmar which bears a longitudinal median carina on pronotum; the new species of the subgenus Akiyamaia (described here) has rather straight lateral margins of pronotum. Therefore the characters used to separate Cypriacis and Buprestis by Kurosawa (1988) are no longer applicable, Hattori & Tanaka (2007) pointed out that the subgenera Himalobuprestis and Akiyamaia differ from the other subgenera of Cypriacis (sensu Kurosawa 1988) by having “male genital apparatus with median emargination in basal margin of parameres”, “pronotum with an obvious longitudinal depression on each side along lateral borders”, “elytra with thick and abruptly elevated costae” on which the punctures are “very fine” and “sparsely scattered”, and the ratio of elytra-length to pronotum-length greater. All these characters are useful for separating the subgenera Himalobuprestis and Akiyamaia from all other generic and subgeneric taxa of Buprestina (sensu Bellamy 2008), and may suggest that these two subgenera constitute a monophyletic group. However it is not legitimate to give Akiyamaia full generic rank at present as there is no evidence available to suggest this group is basal on the phylogenetic tree of the genus Buprestis (sensu Bellamy 2008) which contains many species in various subgenera of unclear phylogenetic position. Only a thorough phylogenetic analysis of the entire genus Buprestis (sensu Bellamy 2008) can clarify the true status of Akiyamaia. As Akiyamaia is currently used as a subgeneric name there is no necessity to retain Himalobuprestis as a separate subgenus, and it was treated by Bellamy (2008)

390 · Zootaxa 4007 (3) © 2015 Magnolia Press HUANG & PAN as a junior synonym of Akiyamaia. In this work, the authors follow Bellamy’s (2008) classification except in his treatment of Yamina. The generic rank of Yamina is supported by Volkovitsh’s (2001) work and also by a recent molecular study (Evans et al. 2014) which also suggests that the genus Pseudhyperantha Saunders 1869 (Chrysochroinae: Dicercini: Haplotrinchina according to Bellamy 2008) is closely related to Yamina and might be a member of Buprestini (see also Bílý et al. 2009) Buprestina is characterized by the “slender maxillary palpi with long and slender apical segment which is longer than wide and longer than each of the preceding segments” (Kurosawa 1988), and by some microscopic antennal characters (Volkovitsh 2001). The following key is applicable to all the genera and subgenera in this subtribe, based on the published information (Obenberger 1941, Kurosawa 1988, Volkovitsh 2001, Hattori & Tanaka 2007). It should be noted that Fabricius, 1775 placed by Kurosawa (1988) into the subgenus Stereosa was reconsidered by Hattori & Tanaka (2007) and Ohmomo & Fukutomi (2013) as a member of the subgenus Cypriacis.

Material and methods

The specimen was collected in flight in the field and was killed with ethyl acetate and dried. To examine the male genitalia, the last two abdominal segments were removed, treated with a weak solution of potassium hydroxide and then preserved in 70% ethanol. Photographs of genitalia were taken with Olympus C-5050 camera mounted on Olympus SZX12 stereomicroscope.

Diagnosis. This new species is similar to Buprestis (Akiyamaia) samanthae from North Myanmar, but can be easily distinguished from the latter by the following combination of characters: 1) lateral margin of pronotum straight in posterior half, not convex; 2) each elytron with eight carinae besides the elevated suture; 3) carinae on elytra narrower and metallic green, not black; 4) metasternum with a complete narrow groove along midline instead of a short and broad sulcus; 5) head wider, about 0.6 times as wide as pronotum; 6) hindwing with vein

MP3a attached to vein MP3b, and with vein MP3+4 not extending a little toward base of wing to form a trace of root; 7) aedeagus stouter, with parameres shorter. This new species is easily distinguishable from all the other known species of the subgenus Akiyamaia by

THE BUPRESTIDAE FROM SOUTH-EASTERN TIBET Zootaxa 4007 (3) © 2015 Magnolia Press · 395 having three additional longitudinal carinae on each elytron in addition to the five normal carinae found in all species of Akiyamaia. Discussion. This new species possesses the following diagnostic characters of Buprestis subgenus Akiyamaia, thus can be easily distinguished from the species belonging to other subgenera of Buprestis: 1) male protibia without a hook or an emargination at internal margin; 2) elytra with abruptly elevated carinae on which very fine punctures sparsely distributed; 3) pronotum with obvious longitudinal depressions near and along lateral margins; 4) basal margin of fused part of parameres in male genitalia emarginated. The closest species to Buprestis (Akiyamaia) intercostata sp. n. seems to be Buprestis (Akiyamaia) samanthae, both species are close in distribution and share the following peculiar characters: 1) pronotum with carina along midline, not with median depression or groove; 2) first abdominal sternite flat between metacoxae, not sulcate; 3) elytra without red markings. Etymology. The specific name, intercostata expresses the peculiar character that additional costae or carinae are inserted at intervals between the normal costae of elytra characteristic for all species of the subgenus Akiyamaia.

An annotated list of the taxa of the subgenus Akiyamaia

1) Buprestis costipennis (Fairmaire, 1891) (Ancylochira)—TL (type locality): Kashmir. General distribution: Afghanistan, India, Pakistan (Kubáň 2006, Bellamy 2008). The following characters were clearly mentioned in original description (Fairmaire, 1891): pronotum with depression along midline; each elytron with 4 carinae, not counting the sutural one; first abdominal ventrite with depression between metacoxae. The specimens from Kashmir illustrated and examined by later authors (Akiyama & Ohmomo 2000, Hattori & Tanaka 2007) fit this description, but were not compared with type material. The aedeagus (Fig. 25) was first examined and illustrated by Hattori & Tanaka (2007), taken from a specimen collected from Kashmir.

Synonym: Buprestis impressicollis Kerremans, 1892; Descarpentries, 1965 (synonym of costipennis)—TL: India. The following characters were clearly mentioned in original description (Kerremans 1892): pronotum with longitudinal median sulcus; each elytron with 4 carinae, not counting the sutural one. Only a holotype was known which was not examined in the later works. Obenberger (1941) noticed the following differences between Buprestis impressicollis and B. costipennis in their original descriptions: color of ventral surface of entire body cupreous and long-haired in costipennis but more shining than on dorsal surface and golden in impressicollis; pronotum narrower than elytra in costipennis but hardly narrower than elytra in impressicollis; intervals between carinae on elytra densely rugose in costipennis but finely granulate in impressicollis; costipennis found in Kashmir whilst impressicollis probably found in East India. However such differences were not found by a comparison between type specimens. Kubáň (2006) and Bellamy (2008) listed impressicollis as a synonym of costipennis.

Synonym: Buprestis kashmirensis Stebbing, 1914; Kubáň, 2006 (synonym of costipennis)—TL: Kalatope, Chamba, North-West Himalaya. In the original description (Stebbing 1914), the authorship of Buprestis kashmirensis was given to Fairmaire who never published this name. The following characters are mentioned in original description: pronotum with “a median longitudinal channel not reaching to base”; elytra each with “six longitudinal and very prominent carinae”, apparently counting the elevated suture; “first abdominal segment with a broad longitudinal furrow medially”. The holotype was illustrated as a colour drawing. Kubáň (2006) synonymised this name with costipennis officially.

2) Buprestis mirabilis Kurosawa, 1969—TL: Tachien, Taiwan. General distribution: Taiwan (Kubáň 2006, Bellamy 2008). This species was originally described from Tachien at the western side of the central mountains of Taiwan, with holotype photographed and figured in colour. Hattori (2001) reported more specimens from some new localities at the eastern side of central mountains of Taiwan, and discussed the individual variations of elytral markings. Hattori & Tanaka (2007) examined and illustrated the aedeagus (Fig. 26) of a male specimen from

396 · Zootaxa 4007 (3) © 2015 Magnolia Press HUANG & PAN central Taiwan. The following diagnostic characters were found in holotype and the additional specimens (Kurosawa 1969, 1988;Hattori 2001; Hattori & Tanaka 2007): pronotum with groove along midline; first abdominal ventrite not sulcate between metacoxae; each elytron with 5 carinae, not counting the elevated suture; elytra with red markings reaching lateral margins of elytra.

3) Buprestis lebisi Descarpentries, 1956—TL: N Yunnan, SW China. General distribution: China (Yunnan), Nepal (Kubáň 2006, Bellamy 2008). This species was originally described on a single female specimen from Yunnan, with exact locality unknown. The holotype was re-described, photographed and figured by Hattori & Tanaka (2007). The following characters are known for the holotype: pronotum with groove along midline; first abdominal ventrite not sulcate between metacoxae; each elytron with 5 carinae, not counting the elevated suture; elytra with red markings extending to apex of elytra.

4) Buprestis samanthae (Hattori & Tanaka, 2007)—TL: Chudu-Razi, N Myanmar. One male holotype and 13 female paratypes are known. Characterized by the following characters: pronotum with a carina along midline; first abdominal sternite not sulcate between metacoxae; each elytron with 5 carinae, not counting the elevated suture; elytra without red markings; metasternum with a short sulcus. The aedeagus (Fig. 24) of holotype was illustrated in the original description.

5) Buprestis intercostata sp. n.—TL: Chayu, SE Tibet. Only the male holotype is known which is characterized by the presence of eight longitudinal carinae on each elytron.
