(Figs.1 C, D; 3A–H)
Type material. Holotype: ♂, CHINA: Motuo County (N29.33°, E95.34°), Xizang (Tibet) Autonomous Region, alt. 2077m, 11. VII. 2013, light-trapped, Wen-bo YI leg.. Paratypes: 3♂ 5♀, same date as holotype.
Diagnosis. This new species resembles A. carinatus Royer, which can be distinguished from the latter species by the male genitalia (Figs. 3 C–H). Other major characters include the length of the head anterior to the eyes, which is moderately prolonged in A. carinatus, more so than in A. motuoensis, the angle and length of the propleuron inner projection, and larger size and different shape female subgenital plate (Fig. 3 B).
Description. Body large size for genus, form elongate. Coloration dull blackish brown, with head, scutellum and central portion of pronotum darker.
Male. Head. Dark brown, minutely alveolate; eyes black, shining, lateral margins weakly sinuate, not confluent except on most posterior part; interspaces between eyes shiny. Preocular portion of head moderately long, 0.70 times as long as eye length. Antennae yellowish brown; rostrum golden, extending to hind coxae.
Thorax. Pronotum massive, blackish brown, surface shining, lighter brown laterally, darker centrally, surface coarsely rugose with distinctly convex, bearing very short decumbent golden setae, posterior portion expanded, lateral margins coarsely granulate, posterolateral angles obtuse, rounded. Scutellum swollen, surface coarsely rugose, shining, dark brown, lateral margins weakly sinuate; mesoscutum cymbiform, bearing short decumbent setae. Hemelytra dark brown, large, complete and rugose, exceeding tip of abdomen bearing short decumbent setae; these setae longer on embolium; clavus, corium and embolium well defined, membrane lighter brown to white (Fig. 1 C). Prosternum sharply carinate medially, propleurae with inner projections deeply notched, with apex slender (Fig. 3 A); mesosternal plate longitudinally carinate medially, broadly tumescent posteromedially.
Abdomen. Dorsal surface dark brown, coarsely rugose, bearing decumbent dark setae, posterolateral angles of segments III–V prolonged into slender spinose projections, coming to acute points posteriorly.
Ventral surface dark brown or brown, weakly pruinose, sparsely covered with fine decumbent golden setae; abdominal segments III–IV weakly and broadly carinate medially, these carinae forming posteriorly directed protruberances which bearing one short stout setae. Abdomen with segments V–VII extremely asymmetrical; segments III–VII with irregular glabrous pits adjacent to and inward of spiracular rosettes, sternum III–V with small posteromedial protuberance. Spines absent from abdominal sternal midline.
Legs. White to brown, shining, covered with fine decumbent golden setae; anterior trochanter, femur, tibiae and tarsi with thick hair pads on inner faces; anterior, middle and hind coxae with combs of golden setae distally; middle trochanter, femur, tibiae and tarsi with thick pads of golden setae posteriorly; hind tibiae and tarsi with long swimming hairs posteriorly; claws curved, golden, tips dark red.
Genitalia. Left paramere extremely expanded in apical third, truncate apically (Figs. 3 C–E). Apex of right paramere narrowly rounded, both parameres with long hairs subapically (Figs. 3 F–H).
Female. Colour and vestiture generally as in male. Subgenital plate (Fig. 3 B) broadly subtriangular; deeply notched and formed a “V” sharp at apex; lateral margins at about middle with narrow tufts of very long setae and ridges set with long golden setae (Fig. 3 B).
Brachypterous form. Unknown.
Distribution. China (Xizang).
Etymology. Referring to the Motuo County in which the type locality situated.
