Anaglyptus zhangjunqii sp. nov. （张ȐṘỘẌƑ牛）

( Figures 9–16 , 19–20, 23–24 )

Description. Male: Length 11.0 mm, humeral width 2.6 mm. Body elongate, finely punctate (except pronotum with coarse reticulate punctation on both sides), reddish-brown to black, clothed with gray and black pubescence. Head mostly reddish-brown, clothed with grayish-white pubescence, denser between antennal insertions, gena clothed with sparse setae on posteroinferior side; back of head, apex of mandible, apical edge of maxillary and labial palpi black. Antennae mostly dull reddish-brown, each antennomere slightly light at base and dark at apex; scape clothed with well-marked grayish-white pubescence, antennomeres I–V fringed with sparse setae below. Pronotum black, evenly clothed with gray pubescence, and several long setae on both sides. Scutellum black, clothed with grayishwhite pubescence. Elytra mostly reddish-brown, clothed with grayish-white and black pubescence, decorated with four black transverse bands: first band on elytral base, flexuose; second band near the middle, relatively wide, interrupted on sides by a small grayish-white spot, anterior margin extending forward to lateral edge of elytra, posterior margin reaching outward to elytral middle; third band at apical fourth, both ends slightly extending backward to lateral edge of elytra; fourth band before apex, reaching to lateral edge of elytra; another nearly unbroken black longitudinal stripe behind the humerus, almost extending backward to elytral apex. Sterna mostly black-brown to black, clothed with gray pubescence, remarkably sparser on middle of prosternum, pro- and mesosternal process yellowish-brown. Sternites I–III black-brown, clothed with grayish-white pubescence, glabrous on posterior margin and with a glabrous spot on each side; sternites IV–V mostly reddish-brown, grayish-white pubescence sparser. Legs mostly reddish-brown, coxae, enlarged part of femora, extreme apex of tibiae and most of tarsi black-brown, grayish-white pubescence and setae on femora and tibiae relatively sparse.

Frons transverse, not convex. Eyes shallowly emarginate at inner edge, upper lobe quite small. Antennae obviously longer than body, exceeding the elytral apex by two segments; antennal insertions elevated, widely separated, inner sides angularly protruded; scape stout, densely and finely punctate; pedicel shortest, antennomere VII longest, ratios of relative lengths of antennomeres I–XI as follow: 6.61;1.74;8.71;7.53;9.12;9.98;10.05;9.93; 8.70;7.77;10.01. Pronotum slightly longer than wide, anterior margin about as wide as posterior margin, both sides slightly expanded on middle; disc convex, lateral margin nearly vertical downward, surface relatively flattened on center, with weak edges formed by reticulate punctures on both sides and a fine longitudinal middle ridged line on posterior half. Scutellum triangular, finely punctate. Elytra convex, elongated, length (from base to end of marginal angle) about 2.65 times as long as humeral width (maximum width), both sides slightly narrow behind humeri, then slightly expanding outward behind middle and then narrow towards apices; apex transversely truncated, marginal angle long spined, sutural angle rounded; base of each elytron provided with a short longitudinal lump at middle. Legs moderate long, femora distinctly claviform, tibiae slightly expanded apically, metafemur about as long as metatibia, not reaching elytral apex; metatarsomere I about as long as metatarsomere II and III combined. Distal abdominal segment with tergite exposed, ventrite nearly straight apically.

Female. Length 12.8 mm, humeral width 3.5 mm. Similar to male, but antennae distinctly shorter than body, ratios of relative lengths of antennomeres I–XI as follow: 4.80;1.63;7.25;6.26;7.45;7.86;7.00;5.97; 5.41;4.50;4.73. Pronotal disc with lateral margins remarkably vertical downward and more distinctly edged, without middle ridged line; distal abdominal ventrite relatively long.

Material examined. Holotype (male), China: Sichuan province, Miyi county, Dachang valley , alt. 3100m, July 18, 2014, coll. by Mengsheng Wang . Paratype: one female, the same data as the holotype. The holotype is deposited in the Enotomological Museum of Yangtze University, and the paratype is deposited at Chen Mu’s private collection .

Distribution. China: Sichuan.

Etymology. The new species is dedicated to Junqi Zhang, a friend of Mr. Chen Mu.

Comments. The new species should be placed into the subgenus Aglaophis Thomson according to antennomeres III–V without distinct apical spines. The new species belongs to A. fasciatus Thomson, 1857 species group characterized by the dark transverse fascia near the middle of elytra, partially or completely broken by a light spot, which includes A. fasciatus Thomson, 1857 , A. longispinis Gardner, 1939 , A. abieticola Holzschuh, 2003 , A. graphellus Holzschuh, 2011 , A. arcanus Miroshnikov, Bi & Lin, 2014 , A. qijuni Viktora & Liu, 2018 . Although the fascia near the middle of elytra vary in those species, A. decemmaculatus ( Gressitt, 1935) , A. ulmiphilus ( Holzschuh, 1982) , A. ambiguus Holzschuh, 1992 and A. kontumensis Viktora, 2019 may also belong to this group.

By the coloration of the body, antennae and legs, the pattern on the middle of the elytra, and the structure of the femora, the new species looks most similar to A. graphellus Holzschuh and A. arcanus Miroshnikov, Bi & Lin in appearance. It differs A. graphellus Holzschuh by the distal abdominal segment exposed, the male elytral apices distinctly clothed with grayish-white decumbent pubescence and the marginal spine shorter (figures 23–24), the elytra with the narrower basal band and the middle fascia with anterior edge clearly extending forward (figures 9, 11), and the different pronotal shape (figures 19–20). It is different from A. arcanus Miroshnikov, Bi & Lin by the antennomeres III–IV nearly without obvious apical spine, antennomeres VII–VIII only clothed with thin grayishwhite pubescence on basal half to three quarters, elytral apices not whole dark, with a distinct grayish-white apical fascia, and more elongated and different shape of pronotum, more rounded humeral angles and different middle fascia on elytra.
