Paratypes : 17 ♂♂ 15 ♀♀, same data as in holotype ( BMNH , 2 ♂♂ 2 ♀♀ in TARI , 1 ♂ 1 ♀ in NMPC , 1 ♂ 1 ♀ in JBCB ).

Measurements. Males: 4.9–5.1 mm ( holotype 5.1 mm ), females: 4.7–5.4 mm . Dorsal side glabrous, oval, convex. Color metallic bluish-black, abdomen yellowish brown, mouthparts brown to black, labrum metallic with brownish margins, legs black, knees usually dark brown. Male ( holotype , Fig. 86 ). Anterior part of head with setae on anterior margin of clypeus and along lateral margins of nasal keel. Interantennal space 1.15 times as wide as transverse diameter of antennal socket. Interocular space wide, 2.1 times as wide as transverse diameter of eye. Antennae filiform, 0.67 times as long as body, length ratio of antennomeres equals 13-6-7-13-13-12 -13-13-13-13-19. Pronotum lustrous, 1.3 times as broad as long, widest in anterior third, densely covered with fine punctures (punctures of the same density as on elytra, but finer). Anterior margin nearly straight, lateral margins rounded, posterior margin straight in middle, lateral parts rounded. Anterior margin with very fine border, lateral margins with broad border, posterior margin moderately bordered. Anterior angles distinctly swollen, elongate, oblique, with setigerous pore on posterior margin of swelling, posterior angles with small pointed tip with setigerous pore, all pores bearing long pale seta, additional short setae visible on anterior third of lateral margins. Elytra 1.40 times as long as wide and 0.72 times as long as body, widest behind middle. Length ratio of protarsomeres I, II, III and V equals 16-12-9-20 , of metatarsomeres I, II, III and V equals 26- 13-9-20 . Prosternal process thinly visible between procoxae. Posterior margin of last ventrite with two short incisions ( Fig. 115 ). Aedeagus symmetrical, subparallel, slightly convergent basally, apex with triangular process with rounded tip ( Fig. 113 ). Female. Interocular space wider, 2.5 time as wide as transverse diameter of eye. Last ventrite subtriangular with apex rounded ( Fig. 118 ). Pygidium with large shallow semicircular incision ( Fig. 116 ). Sternite VIII ( Fig. 114 ) subtriangular with anterior margin moderately rounded and covered with row of setae, tignum slender twice longer than sternite VIII. Spermatheca: nodulus elongate, slightly wider than cornu, cornu C-shaped with inner angle relatively sharp, proximal spermathecal duct suddenly turn in axis 90° ( Fig. 117 ). Distribution. Taiwan (Hualien county). Biology. Unknown. Etymology. Dedicated to Maxwell V. L. Barclay (BMNH) who kindly allowed us to examine Charaea specimens under his curacy including the series of this newly described species. Differential diagnosis. The body is large and oval ( 4.7–5.4 mm ), and the species is similar to Ch. taiwanum , Ch. mimicum and Ch. kelloggi . All four species can be separated by the shape of the aedeagus (compare Figs 5 , 11 , 76 , 113 ). The pronotum of Charaea mimicum and Ch. kelloggi have double punctuation (fine and large) and the lateral pronotal margins possess wide borders while the pronotum of Ch. maybarclayi sp. nov. is only finely punctate and the lateral pronotal margins are moderately wide. Charaea taiwanum differs in antennomeres II and III short and equal and antennomere IV 2.5 times as long as II and III combined (in Ch. maybarclayi sp. nov. antennomere III slightly longer than II, antennomere IV as long II and III combined).
