description: <i>Anomala siamensis</i> (NONFRIED, 1891) (Figs 20, 46–49) <b>Distribution:</b> Thailand; China (<b>new country record</b>): Yunnan; Laos (<b>new country record</b>). <b>Type material</b>: Syntypes [?]. 1  (MFNB), Coll. Nonfried. Siam / Aprosterna siamensis Type Nonfr. [Ohaus’s handwriting] / Anomala siamensis Bang-Pain Type A. F. Nonfried [possibly Nonfried’s handwriting]; 1  (MFNB), Siam Nonfried / Heteroplia n. sp. / Aprosterna siamensis Cotype Nonfr. [Ohaus’s handwriting]. <b>Note</b>: It is not entirely certain that these two specimens from Ohaus’s collection are real syntypes of <i>Aprosterna siamensis</i> NONFRIED, 1891 because they do not bear Nonfried’s type label (compare with the label shown in HORN et al. 1990). <b>Other specimens examined:</b> <b>CHINA: Yunnan</b>: 1  (FLWC), Menglun, Xishuangbanna, 15.IV.2019, Zi-Chun Xiong leg.; <b>LAOS</b>: 1  (CZGG), Laos NW, Nam Tha NPA, 65 km nw Luang Nam Tha, 1050 m, 8-15.IV.2010, S. Murzin leg.; 1  (PPPC), LAOS centr 27.IV.-1.V. 1997. 70 km NE Vientiane, Ban Phabat env., 150 m N 18°16.1'E 103°10.9'E. Jendek &amp; O.

April 2004, 182 m, 14°26.178'N 105°16.631E, Sites &amp; Vitheepradit leg.; 3 , 1  (CZGG), NW Thailand, Mae Hong Son, Pan Huai Po, 1600 m, 9-16.V.1991, leg. P. Pachlátko; 1  (CZGG), NW Thailand, Chom Thong, 24-27.IV.1991, leg. Pacholátko. <b>Remarks</b>: PAULIAN (1959) misidentified <i>Anomala anguliceps</i> as <i>A. siamensis</i>, but later ZORN et al. (2017) corrected this identification based on the male genitalia illustrated in PAULIAN (1959). Also, YANG (1989) misidentified <i>A. anguliceps</i> as <i>A. siamensis</i> when reporting this species from Guizhou, China. Both species mentioned above were also confused by LIN (1987, 1992, 2002b), who consequently described <i>A. corneola</i> LIN, 2002, which was subsequently synonymized with <i>A. anguliceps</i> by PROKOFIEV (2014). In fact, <i>Anomala siamensis</i> is similar to <i>A. bilobata</i> ARROw, 1912 and <i>A. fissilabris</i> ARROw, 1912 rather than <i>A. anguliceps</i>. Both <i>A. bilobata</i> and <i>A. fissilabris</i> have a bilobed clypeus in males, which is the same in males of <i>A. siamensis</i>, while the clypeal front margin is straight in <i>A. anguliceps</i>. <i>Anomala siamensis</i> was previously known only from Thailand, here this species is newly recorded from China and Laos.
