General appearance. – Body length: 15.4 mm, width: 7.9 mm.

Body elongate ovoid, convex in profile.

Color . – Whole body dark brown with dark green metallic luster, weaker on elytra and pygidium ( Fig. 1 & 9).

Head. – Clypeus subtrapezoidal, anterior margin well crooked, moderately reflexed, surface with dense transverse coalescent punctures, each puncture bearing one short yellow setae. Fronto-clypeal suture slightly arcuate forward. Frons with dense punctures which bearing short setae, punctures coalescent anteriorly, interocular distance equals 0.62 times the maximum transverse head width, with several long yellow setae along eyes.

densely punctate, gradually becoming denser transverse punctures to the side, each puncture bearing one short yellow setae; with a weak longitudinal medial line ridged in the posterior half.

Scutellum . – 0.75 times as long as wide, surface with larger punctures than on pronotum, partly transversely confluent.

Elytra . – Surface with regular striae, intervals raised distinctly. Surface densely with transverse punctures, each puncture bearing one short yellow setae. Humeral umbone moderately strong. Lateral margin becoming wider after umbone, epipleuron disappear in posterior 1/3.

Pygidium . – Weakly convex in profile, area slightly protrude before apex.

Surface with reticulate vein,densely covered with yellow setae, longer on apex.

Abdominal ventrites. – Surface with dense transverse punctures in the middle, gradually forming smaller transverse striae to the sides, with several short yellow setae medially, denser and shorter on the sides.

Legs. – Protibia bidentate, apex of terminal tooth rounded, basal tooth sub-right-angle. Mesotibia and metatibia fusiform, surface with dense and coarse longitudinal gullies, inner surface with a row of long setae neatly. Protarsal and mesotarsal outer claw deeply clefted.

Genitalia. – As in Fig. 5-8.

Female ( Fig. 3, 4 & 10). – Body length 15.6 mm, width 8.2 mm. Pronotum more convex in profile. Terminal tooth of protibia longer. Outer margin of vaginal palps rounded, inner margin incurve, surface coarse, densely with long yellow hair.

Measurement. – Male: body length 15.4 mm, width 7.9 mm. Female: body length 14.1-15.3 mm, width 7.5-8.0 mm.

Diagnosis. – So far, twenty one available Anomala species were mentioned in Anomala hirsutula species-group depending on body dorsal surface with dense, fine, short setae ( Keith 2008; Lin 1996; Machatschke 1957; Miyake 1994, 1996; Prokofiev 2021b; Wang 2021c; Wang & Zorn 2021):

- A. yunnana Fairmaire, 1886

- A. hirsutula Nonfried, 1892

- A. pilosella Fairmaire, 1898

- A. lignea Arrow, 1917

- A. itoi Miyake, 1994

- A. iwasei Miyake, 1994

- A. sapa Miyake, 1994

- A. barbellata Lin, 1996

- A. brevihirta Lin, 1996

- A. capillula Lin, 1996

- A. hirsutoides Lin, 1996

- A. montana Lin, 1996

- A. planicauda Lin, 1996 (female holotype) - A. subpilosa Lin, 1996

- A. subtomentella Lin, 1996

- A. subtrinata Lin, 1996

- A. trichophora Lin, 1996

- A. katsurai Miyake, 1996

- A. vietnamica Miyake, 1996

- A. myanmarensis Keith, 2008

- A. dongi Wang, 2021

Most of species in this group show rather similar appearance (except A. yunnana), but we can distinguish them by the shape of male genitalia and female vaginal palps ( Lin 1996).

This new species is related to A. subpilosa ( China: Guizhou, Hubei) and A. vietnamica ( Vietnam) depending on the characteristic of male genitalia by ( Lin 1996; Miyake 1996; Zorn et al., 2017):

- Ventral plate rather short ( Fig. 6 & 40);

- Basal half of parameres broad, anterior half of parameres are slender branch ( Fig. 8, 41 & 43);

- Inner margin of the anterior branches wear short and dense yellow setae ( Fig. 5-8, 39-43).

Anomala yanxui sp. nov. can be distinguished from A. subpilosa and A. vietnamica by the extended branches of two parameres upswept in lateral view and inner margin of two parameres without serration ( Fig. 7, 8, 41 & 43).

Anomala yanxui is different from A. planicauda by the female vaginal palps ( Lin 1996) shorter and surface with denser long yellow hair ( Fig. 10).

Etymology. – The species is named after Mr. Xu Yan, who collected all type specimens.

Distribution (Fig. 61). – China: Yunnan (Maguan).
