Diagnosis. Body large and elongate, greyish-black, basal 3/4 of femora reddish.Antennae long, reaching apical 2/7 of elytra; elytra striate, with aspect ratio over 1.9 in male, and over 1.7 in female; protibiae thickened, strongly curved in apical third, metatibiae strongly recurved; leaf shaped apical lobes of sternite VIII. Description of male. Male ( Fig. 29A, C ). Color greyish-black, antennae, mouthparts, basal 3/4 of femora, apical portions of tibiae, and tarsi reddish brown, shagreened. Body slender, length 22.3–26.3 mm , width 7.6–8.6 mm , moderately convex, noticeably constricted between pronotum and elytra. Head ( Fig. 31E, J ) transversely subquadrate, densely and markedly punctate, with outer margin strongly notched between genae and clypeus; clypeus transversely hexagonal, gently bent downwards in front, with anterior margin straight, clypeal transverse impression short, marked to absent; frontoclypeal suture deeply grooved, becoming weaker laterally, widely U-shaped; genae strongly raised, depressed before eyes, strongly and roundly produced anterolaterally; frons broad, anterior part gradually sloping forwards, vertexal lateral impressions narrow, distinct to vague, extending backward and curved oppositely, forming a U-shaped impressions; eyes transversely reniform, strongly convex laterally; inner ocular sulci shallowly depressed along inner margins, becoming broader posteriad; tempora slightly convex, punctures as those on frons. OI = 44.0–49.5. Antennae ( Fig. 32E ) slender, reaching basal 2/7 of elytra, with antennomeres weakly thickened to apices; relative lengths of antennomeres: 0.92: 0.41: 1.53: 1.36: 1.53: 1.48: 1.36: 1.34: 1.26: 1.14: 1.22. Mentum ( Fig. 31J ) inversely trapezoidal, lateral margins straight; medial surface coarsely punctate, with several large pores bearing long setae; gradually rising from base to apex, depressed along each side. Pronotum ( Fig. 31O ) quadrate, PW/PL = 0.93–1.02, widest slightly before anterior third, anterior margin weakly rounded, anterior marginal border thin, vague; lateral margins weakly rounded, lateral marginal borders thin, visible in dorsal view along anterior half; posterior margin weakly rounded, emarginate in middle, posterior marginal border marked; anterior angles rounded, posterior angles obtuse; disc moderately convex, shagreened, finely and sparsely punctate. Scutellum widely triangular, glossy, finely punctate. Elytra elongate ovate, widest near middle, EL/EW = 1.90–1.99; strongly convex, highest near middle; with 9 continuous furrowed striae, 1 st branching, and 8 th ending in apical seventh of elytra; 1 st , 2 th , 3 rd , 7 th , and 8 th converged at ends, 4 th , 5 th , and 6 th converging in apical seventh, 2 nd and 3 rd converging at fore-ends; intervals strongly convex, glossy, coarsely wrinkled on apical seventh, sparsely and finely punctate. Prosternum ( Fig. 31T ) shagreened, finely and sparsely punctate; prosternal process almost vertically declivous behind coxae, pointed at apex; hypomeron moderately rugulose, shagreened. Metasternum smooth, metaventral anterior process finely wrinkled. Abdomen depressed, somewhat wrinkled, densely and finely punctate, sternites III and IV sulcate on sides. Legs slender. Protibiae ( Fig. 32S ) thick, strongly curved in apical third, more than apical half of inner margins emarginate and pubescent; mesotibiae ( Fig. 32T ) weakly curved in apical fourth, apical half of inner margins emarginate and pubescent; metatibiae ( Fig. 32U ) strongly curved in middle, apical 3/5 of inner margins pubescent, outer margins depressed before apices. Aedeagus ( Fig. 33E ) elongated, curved in lateral view; parameres slender, 0.21 as long as the total length, with ovoid apex. Sternite VIII ( Fig. 33K ) strongly sclerotized, with leaf shaped apical lobes in lateral view, constricted at each base, produced posteriorly, apex pointed. Female ( Fig. 29B, D ). Wider than male, length 24.3–26.5 mm . OI = 44.6–47.1, PW/PL = 1.08–1.10.Elytra more convex, highest in middle, EL/EW = 1.68–1.90; abdomen straight in lateral view. Ovipositor ( Fig. 31Y ) elongate, sclerotized and acinaciform, apex of gonocoxite acute. Comparative notes. Morphostenophanes lincangensis looks like a longer M . atavus . Its strongly elongate and less convex elytra, thicker tibiae, curved metatibiae, and shape of apical lobes of sternite VIII are shared with M . birmanicus , M . bannaensis and M . vietnamicus . M . lincangensis can be distinguished from M . birmanicus by the latter possessing more elongate antennae reaching apical third of elytra, greenish colored pronotum widest in anterior 2/5, much wider elytra with bronze metallic luster. M . lincangensis can be distinguished from M . bannaensis by the latter having tubercules of different sizes along each elytral interval. M . lincangensis can be distinguished from M . vietnamicus by the latter having bronzy color, male pro- and mesotibiae bugled in apical 2/5. Distribution. ( Map 1 ) CHINA : Yunnan . Etymology. The new species is named after its type locality, Lincang City.
