description: Amphiops mirabilis Sharp, 1890
(Figures 4A–I, and 5C–F)
Amphiops mirabilis Sharp, 1890: 355 (specific rank confirmed by Balfour-Browne 1939: 307). – Type locality: Sri Lanka [“(Ceylon): Kandy”].
Amphiops yunnanensis Pu, 1963: 80. Syn. nov. – Type locality: China (Yunnan: Xiaomengyang).
Type material examined
Amphiops yunnanensis. HOLOTYPE: female (IZCAS: IOZ(E)220509), with two collection data “Xiao Mengyang, 850 m, 4 May 1974, Qiuzhou Liang leg.” (transcript from Chinese), and another label with same data in Russian, with a red label “ HOLOTYPE Amphiops yunnanensis, det. Pu Zhelong ” (handwriting) and a label “ Amphiops yunnanensis ” (handwritten).

Differential diagnosis
Pronotum clearly with a posterolateral angle although strongly rounded (Figure 4D), without wrinkles and elytra without ridges. Elytra with clear large strial punctures and sparse finer small punctures (Figure 4B, E, G–I). Aedeagus with median lobe only slighter shorter than parameres, parameres widened apically (Figure 5C–F).

Taxonomic note
Pu (1963) described Amphiops yunnanensis based on a female. In the original description, he compared A.yunnanensis with A.annamita, A.mater and A.pedestris varians Orchymont, all now considered as synonyms of A.mater. It is probable that Pu (1963)
did not know that A.mirabilis also occurs in China. I have been able to check the type in IZCAS. It is clear that A.yunnanensis is conspecific with A.mirabilis.
Distribution
China (Shandong, Jiangsu, Guangdong, Guangxi, Hainan, Yunnan), Myanmar, Indonesia (Java), Sri Lanka. New for Jiangsu, Guangdong, Guangxi, Hainan.
Key to the Chinese species of Amphiops Erichson
1. Pronotum without distinct posterior angle, posterolateral margin simply continuously rounded (Figures 1F, 2F,I). Elytra at most with a few large punctures forming 2–3 short lateral punctural series basally. Mesocoxae narrowly separated (Figure 2J). Metaventrite not truncate, without anterior transverse ridge. Metafemora smooth and finely punctate. ........................ 2 Pronotum with a posterolateral angle although strongly rounded (Figure 4D). Elytra with 10 clear large punctural striae. Mesocoxae broadly separated (Figure 3A). Metaventrite truncate anteriorly and with anterior transverse ridge (Figure 3A). Metafemora coarsely punctate, pubescent basally ...................................................................................... 3
2. Pronotum and elytra with strong punctures, intervals between punctures about 1.3–1.5 × the diameter of a puncture, systematic punctures as large as ground punctures (Figures 2G, I). Median lobe of the aedeagus narrower, triangular apically, broadly notched behind apex on each side (Figure 5B). .............................................................................. A. coelopunctatus sp. nov. Pronotum and elytra with extremely fine punctures, intervals between punctures at least c.3.5 × the diameter of a puncture, systematic punctures much coarser than ground punctures (Figure 1A, B, E). Median lobe of aedeagus broader, rounded apically, with a small notch behind apex on each side (Figure 5A) .................................................................................. A. coomani
3. Pronotum with some longitudinal wrinkles anteriorly (Figure 2A); elytra with weak ridges on inner portion (Figure 2C), clearly striate laterally and apically (Figure 2C), outer five intervals distinctly elevated (Figure 2B). ........................................................................... A. caristripus Pronotum without wrinkles and elytra without ridges……………………4
4. Elytra with coarser serial punctures and sparse finer small punctures (Figures 4B, E, G–I). Aedeagus with median lobe only slighter shorter than parameres, parameres widened apically (Figure 5C–F). .................... A. mirabilis Elytra with smaller serial punctures and denser and coarser small punctures laterally (Figure 3B–E). Aedeagus with median lobe distinctly shorter than parameres, parameres not widened apically (Figure 5G, H)………………………………………………………… A. mater
