Habitus as in Fig. 1View FIGURES 1–2.

Head moderately large ( Fig. 15View FIGURES 15–35), 1.5–1.7 times as wide as long; middle portion slightly elevated, usually with two indistinct transverse impressions between eyes, with distinct, deep, short grooves in front of ocelli, and with narrow irregular impression between ocelli; postocular ridge distinct, acute, with surface between postocular ridge and posterior margin of eye as long as the two or three nearest combined ommatidia; anterior portion between antennal insertion and anterior margin of eye with small, distinct semicircular notch. Eyes large, convex. Ocelli large, situated at about level of postocular ridges; distance between ocelli slightly longer than distance between ocellus and posterior margin of eye. Labrum with widely rounded latero-apical portions, deep medioapical emargination, and with elongate basolateral projections ( Fig. 3View FIGURES 3–14). Mandibles moderately short and wide, with small tooth near apex of right mandible ( Fig. 6View FIGURES 3–14). Submentum and labium narrow, with markedly transverse preapical labial palpomeres ( Fig. 12View FIGURES 3–14). Apical segment of maxillary palpus more than twice as long as preceding segment; galea widened in apical portion; lacinia moderately short, with several preapical teeth ( Fig. 9View FIGURES 3–14). Gular sutures with shortest distance slightly behind level of posterior margins of eyes ( Fig. 15View FIGURES 15–35). Antenna moderately short, exceeding apical fourth of elytra when reclined; length × width of antennomeres (holotype): 1: 0.13 × 0.06; 2: 0.11 × 0.03; 3: 0.11 × 0.02; 4: 0.11 × 0.03; 5–6: 0.11 × 0.04; 7: 0.11 × 0.05; 8: 0.09 × 0.05; 9: 0.09 × 0.06; 10: 0.08 × 0.06; 11: 0.15 × 0.07.

Pronotum transverse, about twice or slightly more than twice as wide as long, 1.5 times as wide as head, widest slightly anterior to, or at about middle, slightly more narrowed posteriad than anteriad; apical margin markedly rounded, distinctly narrower than posterior margin; anterior angles widely rounded, indistinctly protruded anteriad; posterior angles more or less obtuse; lateral edges of pronotum with indistinct flattened crenulation; pronotum with very wide elevated middle portion, with indistinct short longitudinal impression at medioapical third (invisible in some paratypes), with small, indistinct to distinct semioval impression on mediobasal third; lateral portions moderately wide, slightly explanate, each with small deep pit approximately in the middle. Prothorax ( Fig. 18View FIGURES 15–35) with long, narrow intercoxal process and strongly protruded mesosternal processes. Mesothorax ( Fig. 27View FIGURES 15–35) with acute, long intercoxal process, reaching posterior margin of mesocoxae. Scutellum ( Fig. 21View FIGURES 15–35) with widely rounded apex. Metathorax as in Fig. 30View FIGURES 15–35. Metendosternite as in Fig. 33View FIGURES 15–35.

Elytra convex, slightly longer than wide, markedly more than twice as long as pronotum, slightly widened in middle, reaching apical margin of abdominal tergites IV to VI, with widely rounded apical margins, truncate at suture; shoulders of elytra rounded, not protruding anteriad ( Fig. 24View FIGURES 15–35); lateral portions of elytra narrow, slightly explanate, latero-apical margins with indistinct, small, irregular crenulation; surface of each elytron without elevations, but some paratypes with very indistinct longitudinal elevations between punctures in middle. Wings fully developed.

Legs moderately long and slender; mesotibiae covered by elongate setae; metatarsus short, markedly more than twice as long as metatibia.

Abdomen markedly narrower than elytra, with a pair of small transverse tomentose wing-folding spots in middle of tergite V; apical margin of abdominal tergite VII with fine palisade fringe.

Male. Protarsomeres 1–4 distinctly widened. Apical margins of abdominal tergite VIII ( Fig. 36View FIGURES 36–47) and sternite VIII ( Fig. 39View FIGURES 36–47) slightly sinuate. Aedeagus ( Fig. 51View FIGURES 51–54) moderately wide, with widely truncate apex; parameres narrow, curved in apical portion, distinctly exceeding apex of median lobe, with two long apical setae; internal sac wide and moderately long, spirally rolled in basal portion. Aedeagus laterally as in Fig. 52View FIGURES 51–54.

Female. Protarsomeres 1–4 narrow. Apical margin of abdominal tergite VIII ( Fig. 42View FIGURES 36–47) straight. Apical margin of abdominal sternite VIII ( Fig. 45View FIGURES 36–47) widely rounded. Genital segment as in Fig. 48View FIGURES 48–50.

Comparative notes. Based on the coloration, general shape of the elytra and aedeagus, A. consanguineum  sp.n. is similar to Himalayan A. jaegeri  sp.n., from which it differs by the markedly wider pronotum and details of both internal and external characters of the aedeagus.

Distribution. The species is known from several localities in the Gaoligong Shan and Diancang Shan ranges in Yunnan, China ( Fig. 55View FIGURE 55).

Bionomics. Specimens were collected at elevations from 3000 to 3400 m a.s.l. The specimens were taken by sifting litter, mosses, and debris in broadleaved bushes, forests with Rhododendron  ; some specimens were taken by sifting from leaf litter, moss and various debris under rhododendron  and various broadleaved shrubs near small creeks and snowfields (locality: C169). Ten specimens (locality: CH 07-24) were collected together with A. latissimum Shavrin & Smetana, 2018  (for a photograph of the type locality of this species see in Shavrin & Smetana (2018: Fig. 73View FIGURES 73–77)); 14 specimens (locality: CH 07-21) were collected together with A. splendidulum Shavrin & Smetana, 2018  (for a photograph of the type locality of this species see in Shavrin & Smetana (2018: Fig. 93)); two specimens (locality: C 2005-16) were collected together with Mannerheimia grandilobata Shavrin, 2018  (for a photograph of the type locality of this species see in Shavrin (2018: Fig. 11View FIGURES 3–14).

Etymology. The specific epithet (Latin adjective: related) refers to the similarity of this species to A. jaegeri  sp.n.
