Anoplophora rugicollis Wang, Xie & Wang , sp. nov.

( Figs. 1–10 )

Material examined. Holotype (female): China, Yunnan, Mojiang Hani Autonomous County, 18 August, 2008, Xinyong Huang leg. ; Paratype: 1 female, Vietnam: Lào Cai Province, Sa Pa, July , 2019, local leg .

Distribution. China (Yunnan); Vietnam.

Description. Female. Length 34.0– 35.5 mm, humeral width 12.0– 12.5 mm. Body black, clothed with appressed bright bluish, white to bluish-white pubescence, translucent pubescence and black erect hairs, with metallic green luster.

Color and pubescence: Body blackish, head clothed with inconspicuous bluish pubescence on inner margin of lower eye lobe, lower margin of gena, base of labrum and outside of basal mandible (hardly visible to naked eye), with black erect hairs on antennal tubercles; lower margin of gena and partial mouthpart (especially conspicuous on basal labrum and outside of basal mandible). Antenna with scape clothed with inconspicuous bluish pubescence and the succeeding antennomeres clothed with dense bluish-grey pubescence except at apices (middle of antennomere XI more or less presents black annulation), pubescence color gradually becoming pale towards terminal in some degree; basal antennomeres clothed with sparse black hairs below, hairs on scape more conspicuous and denser; apex of antennomeres III–IV distinctly tufted with black hairs ventrally, tufts on following antennomeres gradually indistinct. Pronotum fringed with dense reddish short hairs and sparse black hairs on anterior margin, scattered with long black hairs before and after lateral spine, and clothed with translucent appressed pubescence below the lateral spine; disc nearly glabrous, either side of middle of anterior half clothed with 20–30 very short bluish setae which are hardly visible to naked eye but can be visible under the anatomical lens. Scutellum clothed with translucent pubescence, sparse laterally and quite dense medially. Each elytron scattered with about 13 irregularly-sized patches of white to bluish-white pubescence, of which 7 patches arranged in a longitudinal row along outer margin, and the largest one at the middle of elytron, transversely extending from center to lateral margin; surface without erect hairs, epipleuron fringed with black short hairs. Ventral surface clothed with bluish pubescence, translucent pubescence and erect black hairs. Prosternum clothed with dense bluish pubescence and sparse black hairs, hairs on prosternal process denser and more conspicuous; mesepisternum, mesepimeron and mesosternum clothed with dense translucent pubescence and sparse black hairs, hairs on mesosternal process denser and more conspicuous; metepisternum and metasternum clothed with dense translucent pubescence, mixed with sparse bluish pubescence on posterior half of metepisternum and completely replaced with dense bluish pubescence on central area of metasternum, whole metepisternum and metasternum scattered with sparse black hairs. Sternites clothed with bluish pubescence and black hairs, both of which are sparser than that on metasternum, distal sternite fringed with short pubescence apically. Legs clothed with dense bluish and translucent pubescence, coxa, trochanter and ventral side of proleg scattered with sparse erect black hairs; femur mostly clothed with bluish pubescence, denser on ventral side; tibia mostly clothed bright blue pubescence, extreme base black and apex clothed with dense black bristle; tarsus clothed bright blue pubescence dorsally.

Structure: Head finish, sparsely micropunctate, deeply depressed between antennal insertions; frons quadrate in shape from anterior perspective. Frons quadrate, slightly bulged, with a distinct median sulcus extending to occiput; vertex rounded, gena somewhat inflated. Eye deeply emarginate, lower lobe taller than wide, slightly shorter than genae. Antennae longer than body, about 1.4 times as long as body, antennal tubercles strongly elevated, scape stout, slightly flat, thickened apically, with a broad cicatrix; antennomere III longest, about 1.7 times as long as scape, antennomeres IV–X successively decreased in length, antennomere XI about as long as V. Pronotum wider than long, disc distinctly depressed and transversely rugous, with relatively flattened surface without lateral calli, provided with a small, quite feeble posteromedian callus and a quite vague longitudinal median sulcus, either side of posterior half equipped with several granular punctures; lateral spine conical with subacute apex, directed laterally. Scutellum tongue-shaped, with slightly rounded apex. Elytra convex, shiny, with strong iridescent copper green sheen, about 2.0 times as long as the width across humeri, apex broadly rounded; surface provided with microreticulations and micropunctations, without granules and erect hairs, a distinct depression presents after scutellum. Mesosternal intercoxal process tuberculate. Apex of terminal ventrite bilobed with strong notch at middle. Legs moderately long, femur slightly clavate.

Female genitalia ( Figs. 8–10 ). Setae on sternites VII–VIII denser than that on tergites, which forming a broad patch separated by a narrow glabrous midline. Spermatheca inserts in the bursa copulatrix at the one-thirds distance from blind end. Spermathecal duct short. Spermathecal capsule membranous and subsemicircular basally, sclerotized and gradually expanded apically, strongly curved and reversed medianly, apex of blind end rounded. Spermathecal gland long, with extreme base strongly constricted and sclerotized.

Remarks. The new species is distinctive due to the pronotum with distinct transverse or nearly transverse wrinkles and antennomeres III–IV with the apices distinctly tufted with black hairs ventrally. It is very similar to A. puxian Wang & He, 2021 by the similar lateral pronotal spine, elytral color and elytral markings color, and elytral humeri without granules. However, it can be easy distinguished from A. puxian by the antennomeres II–XI mostly clothed with dense bluish pubescence, only the apex black, pronotum wholly with distinct transverse or nearly transverse wrinkles on disc, without umbilicated granules, and each elytron with large, prominent, separated sub-oval hair patches (except the middle one, which appears to be two patches merged into one transverse patches).

Etymology. The species is named for the pronotum with transverse wrinkles on disc. The Chinese name is designated as Iḃsĸ牛.
