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) .

Amphiops mirabilis View in CoL . Not examined.

Differential diagnosis

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

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 View in CoL

1. Pronotum without distinct posterior angle, posterolateral margin simply continuously rounded ( Figures 1F View Figure 1 , 2F,I View Figure 2 ). Elytra at most with a few large punctures forming 2–3 short lateral punctural series basally. Mesocoxae narrowly separated ( Figure 2J View Figure 2 ). Metaventrite not truncate, without anterior transverse ridge. Metafemora smooth and finely punctate. ........................ 2 Pronotum with a posterolateral angle although strongly rounded ( Figure 4D View Figure 4 ). Elytra with 10 clear large punctural striae. Mesocoxae broadly separated ( Figure 3A View Figure 3 ). Metaventrite truncate anteriorly and with anterior transverse ridge ( Figure 3A View Figure 3 ). 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 View Figure 2 ). Median lobe of the aedeagus narrower, triangular apically, broadly notched behind apex on each side ( Figure 5B View Figure 5 ). .............................................................................. A. coelopunctatus View in CoL 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 View Figure 1 ). Median lobe of aedeagus broader, rounded apically, with a small notch behind apex on each side ( Figure 5A View Figure 5 ) .................................................................................. A. coomani View in CoL

3. Pronotum with some longitudinal wrinkles anteriorly ( Figure 2A View Figure 2 ); elytra with weak ridges on inner portion ( Figure 2C View Figure 2 ), clearly striate laterally and apically ( Figure 2C View Figure 2 ), outer five intervals distinctly elevated ( Figure 2B View Figure 2 ). ........................................................................... A. caristripus Pronotum View in CoL without wrinkles and elytra without ridges……………………4

4. Elytra with coarser serial punctures and sparse finer small punctures ( Figures 4B, E, G–I View Figure 4 ). Aedeagus with median lobe only slighter shorter than parameres, parameres widened apically ( Figure 5C–F View Figure 5 ). .................... A. mirabilis Elytra View in CoL with smaller serial punctures and denser and coarser small punctures laterally ( Figure 3B–E View Figure 3 ). Aedeagus with median lobe distinctly shorter than parameres, parameres not widened apically ( Figure 5G, H View Figure 5 )………………………………………………………… A. mater View in CoL
