AE76878F855C797CFF51FCE2FE9FFBF2.taxon	diagnosis	Diagnosis. Based on the long antennal club, elytra densely and evenly covered with setae, bidentate protibia, apical portion of pygidium not narrowed but more or less rounded, short mesometasternal process, plump lateral maculation of dense white setae on abdominal segments 1 – 5, and symmetrical parameres, this new species is similar to the three species in phupanensis species group from China, Indochina, and India (Gupta et al. 2023; Li et al. 2010): M. phupanensis Keith, 2008 (China: Yunnan; Laos, Vietnam); M. arunachalensis Gupta, Keith, Bhunia, Das, Ghosh & Chandra, 2023 (India), and M. lachungensis Gupta, Keith, Bhunia, Das, Ghosh & Chandra, 2023 (India). We can distinguish this new species from M. phupanensis by the shorter antennal club (Fig. 4) (antennal club rather long in M. phupanensis, Fig. 25), posterior angles of pronotum sub-right-angle, less extended (posterior angles of pronotum acute, rather prolonged in M. phupanensis, Fig. 25), and parameres with narrower apical process (with rounded apical process in M. phupanensis, from fig. 16 in Keith 2008), from M. lachungensis by the protibia strongly bidentate (proximal tooth protibia rather weak in M. lachungensis, from fig. 39 in Gupta et al. 2023), scutellum densely and finely punctate (scutellum sparely punctate in M. lachungensis, from fig. 36 in Gupta et al. 2023), lateral patches of abdominal segments (Fig. 7) white, propygidium with elongated white band laterally (lateral patches of abdominal segments yellow, propygidium without white band laterally in M. lachungensis, from fig. 40 in Gupta et al. 2023), and apical process (Fig. 9) of right parameres larger (apical process same sized in M. lachungensis, from fig. 44 in Gupta et al. 2023). Melolontha daliensis new species is rather similar to M. arunachalensis in external characteristics, but the elytra 1.47 – 1.50 times as long as wide in dorsal view and sides more parallel (1.28 times as long as wide in M. arunachalensis, from fig. 3 in Gupta et al. 2023), proximal tooth (Fig. 5) of protibia acute and slightly prolonged (proximal tooth of protibia sub-right-angle, not prolonged in M. arunachalensis, from fig. 29 in Gupta et al. 2023), lateral patches of abdominal segment 4 larger and more plump (lateral patches of abdominal segment 4 weak in M. arunachalensis, from fig. 32 in Gupta et al. 2023), and dorsal process of parameres different in size, outer side of each parameres strongly ridged (parameres symmetric, outer side of each paramere weakly and rounded bulged in M. arunachalensis, from figs 43, 55 in Gupta et al. 2023).	en	Wang, Fa-Lei, Wang, Zhen, Xiong, Zi-Chun, Qiu, Jian-Yue (2025): Two new species and one new record of the genus Melolontha Fabricius, 1775 from China (Coleoptera: Scarabaeidae: Melolonthinae).

Melolontha tricostata Brenske, 1903 from Kuku-nor (Tibet) is a junior synonym of M. costipennis according to Petrovitz (1969). Nowadays, Kuku-nor is the Qinghai Lake of Qinghai province.	en	Wang, Fa-Lei, Wang, Zhen, Xiong, Zi-Chun, Qiu, Jian-Yue (2025): Two new species and one new record of the genus Melolontha Fabricius, 1775 from China (Coleoptera: Scarabaeidae: Melolonthinae).

AE76878F85577975FF51FC18FB48FD4A.taxon	discussion	Remarks. Ren et al. (2019) recorded the nominate subspecies M. frater frater Arrow, 1913 (type locality: Japan) from Ningxia which is close to the type locality of M. frater gobiensis. Whether the species recorded by Ren et al. (2019) from northern China is really M. frater frater is not yet clear and requires further study.	en	Wang, Fa-Lei, Wang, Zhen, Xiong, Zi-Chun, Qiu, Jian-Yue (2025): Two new species and one new record of the genus Melolontha Fabricius, 1775 from China (Coleoptera: Scarabaeidae: Melolonthinae).

AE76878F85577975FF51FC18FB48FD4A.taxon	discussion	Remarks. Melolontha japonica was originally described from Japan and also recorded from northeastern China in the checklist of Bezborodov (2018). These specimens and records from Chinese mainland were not checked and verified in this study. Depending on the distribution of the other members of this group (similar appearance and genitalia), all of them were collected on the islands of eastern Asia (Li et al. 2010): Japan or Taiwan. Significantly, Melolontha frater (see remark on M. frater gobiensis) was recorded from Japan and Chinese mainland. Additionally, M. insulana (Moser, 1918) was recorded from Taiwan before (Li et al. 2010), but one male from Zhejiang (new distribution record: 1 male, China, Zhangjiang, Qingan county, VII. 2024, Su-Tong Zhang leg.) was examined by us. Whether the distribution from northeastern China published by Bezborodov (2018) is based on true Melolontha japonica is not yet clear and requires additional study.	en	Wang, Fa-Lei, Wang, Zhen, Xiong, Zi-Chun, Qiu, Jian-Yue (2025): Two new species and one new record of the genus Melolontha Fabricius, 1775 from China (Coleoptera: Scarabaeidae: Melolonthinae).

AE76878F85577975FF51FC18FB48FD4A.taxon	discussion	Remarks. Liu et al. (1997) recorded M. hippocastani mongolica from most of the northern provinces of China and also illustrated the male genitalia (compare with Kryzhanovsky 1978: figs 21 – 23) which completely differ from the nominate subspecies M. hippocastani hippocastani Fabricius, 1801. Ren et al. (2019) also done the same work but only illustrated the dorsal habitus. All records by Liu et al. (1997) and Ren et al. (2019) within northern China need to be verified.	en	Wang, Fa-Lei, Wang, Zhen, Xiong, Zi-Chun, Qiu, Jian-Yue (2025): Two new species and one new record of the genus Melolontha Fabricius, 1775 from China (Coleoptera: Scarabaeidae: Melolonthinae).
