Type locality. China ( Hainan Island: Qiongzhong) .

Examined specimens. CHINA: 1 ♂ ( holotype); Hainan, Qiongzhong ; 20 May 1963; Io Chou leg . ( CAU). 1 ♂; Hainan, Ledong , Jianfengling Mt .; 18.74391°N, 108.84336°E; 981 m;

15 May 2009; Xin-Lei Huang leg. ( IZCAS). 1 ♂; Hainan, Ledong, Jianfengling Mt .; 18.73346° N, 108.83850°E; 800 m; 5 May 2008; Qi-Fei Liu leg. ( CCW).

Male measurements (mm). Body length: 20.40–20.45; length of pronotum: 2.15–2.19; length of fore femora: 3.25–3.30; length of middle femora: 5.25–5.30; length of hind femora: 5.80–5.85; length of tegmina: 17.10–17.20; length of cerci: 2.40–2.45; head width: 4.55–4.58.

Notes. Generally,the genitalia and overall appearance of A. hainana are very similar to those of A. chinensis ( Figure 3 View Figure 3 (c)). Amorphoscelis hainana differs from A. chinensis by its smaller size and paler colouration and by the morphology of the male genitalia ( Yang 2002). According to the descriptions of Yang (2002) and Roy (2011), the male genitalia of this species bears a sharp lateral extension of the apical process of the left phallomere and a small peak on the extension. However,we did not observe this feature after dissecting two topotypic specimens from Hainan ( Figure 5 View Figure 5 (h)). Examination of more A. hainana topotypes is necessary to clarify the variation of the male genitalia and its relationship with other congeners.

Distribution. China ( Hainan Island).
