Description of holotype ( Fig. 11, 12, 15-20)

General appearance. – Body length: 15.5 mm, width: 8.0mm.

Body elongate ovoid, convex in profile.

Color . – Head metallic green and coppery, antennal club brown, footstalks yellow. Pronotum mostly yellow, with two disjoint, broad metallic green longitudinal bands. Scutellum brown, sides darker. Anterior 1/3 of elytra yellow, a broad, zigzag black band from median sides to suture, behind black band with a wiggly transverse yellow band from sides to sutural, posterior 1/3 of elytra dark brown. Pygidium yellow with weak metallic green luster, each side with metallic green broad patch, anterior corners yellow. Ventral surface dark mostly metallic green and coppery, anterior 1/2 of abdominal ventrite 1 yellow, each side of abdominal ventrites 2-4 and propygidium with yellow spots, posterior margin of propygidium yellow. Metasternum blackish-green, with a large yellow spot laterally, metacoxa yellow. Tarsus, protibia, mesotibia (partly), metatibia, and all the joints of legs dark green, all femurs yellow.

Head. – Clypeus approximatively semicircular, width more than twice as length, anterior corners broad rounded, anterior margin slightly reflexed, surface densely rugo-punctate. Fronto-clypeal suture slightly arcuate backward. Frons densely punctate, punctures coalescent posterior of fronto-clypeal suture, interocular distance equals 0.63 times the maximum transverse head width. Vertex with dense, weak punctures. Antennal club shorter than footstalks.

Pronotum. – Wide trapezoid, sides convergent before middle. Anterior marginal line complete, posterior marginal line weak. Anterior angles acute, posterior angles obtuse, rounded. Surface densely and finely punctate, sparer on the side.

Scutellum . – 0.70 times as long as wide, surface densely punctate.

Elytra . – Surface with regular striae, intervals raised distinctly, rather weak anteriorly, interval beside sutural interval board. Surface with dense punctures, epipleuron narrow, disappear on posterior 1/3 of lateral margin.

1, 2 & 5 - 9. Holotype, ♂. 3, 4 & 10. Paratype, ♀. 1 -4. Habitus. 5-8. ♂ genitalia. 9. Pygidium . 10. Vaginal palps. 1, 3 & 5. Dorsal view. 2, 4 & 6. Ventral view. 7. Lateral view from left. 8. Lateral view from right.

Pygidium . – Weakly convex in profile, area before apex angle raised. Surface densely transverse striae, forming a striolation which is arranged concentrically around the bulge, apex with yellow setae.

Abdominal ventrites. – Surface with dense, shallow transverse punctures, posterior margin smooth, each ventrite with a transverse row of long yellow setae, setae on ventrites 2-3 rather spare.

Protibia bidentate, terminal tooth prolonged, basal tooth acute. Mesotibia and metatibia fusiform, inner surface with a row of long setae. Protarsal and mesotarsal outer claw clefted.

Genitalia. – As in Fig. 16-19.

Female ( Fig. 13 & 14). – Pronotum more convex in profile, the lateral margins of pronotum more rounded. Terminal tooth of protibia wider, last joint of protarsal slenderer.

Measurement. – Male: body length 15.5 mm, width 8.0 mm. Female: body length 15.5-16.6 mm, width 7.8-8.5 mm.

Diagnosis. – Depending on male genitalia, Anomala semiserrata sp. nov. is similar to six species ( Lin 1999, 2002; Ohaus 1914; Prokofiev 2013; Zorn 2005):

- A. flavofasciata Arrow, 1912 ( Bhutan, India, Nepal)

- A. spilopteroides Ohaus, 1914 ( China: Guangxi, Vietnam)

- A. transversa Lin, 1999 ( China: Yunnan)

- A. projecta Lin, 2002 ( China: Hainan)

- A. accincta Prokofiev, 2013 ( Vietnam)

- A. bulbicaula Prokofiev, 2013 ( Vietnam)

Species above show common characteristics as:

- Body color brown or dark brown;

- Elytra always with wiggly transverse band, sometimes discrete; several parts of parameres have wrinkled membranes (surface only wrinkled in A. spilopteroides) ( Fig. 16-19, 44-55);

- Left paramere has an elongated ossific branch, and sometimes the branch is encysted in the wrinkled membrane (A. flavofasciata).

The new species can be distinguished from all the species above by head with stronger metallic green luster, pronotum with two disjoint, broad metallic green longitudinal bands ( Fig. 11, 13 & 14), pygidium predominantly yellow, and apex of the branch of left paramere rather broad, only left margin with successive saw-teeth ( Fig. 16).

Etymology. – The specific epithet refers to the right margin of the left paramere (in dorsal view) bearing successive saw-teeth.

Distribution (Fig. 61). – China: Yunnan (Fugong, Lancang, Puer, and Baoshan).
