Type material. Holotype: male, CHINA, Guangdong province, Qingyuan city, Shimentai National Nature Reserve , altitude 126m, 11-Ⅴ-2021, leg. M. Wang (voucher number “ SCAU HA09 ”) . Paratype: 1 female: with the same data as holotype (voucher number “ SCAU HA10 ”) , 2 male, 1 female: CHINA, Guangdong province, Shaoguan city, Nanling National Nature Reserve , 22- Ⅴ -2021, leg. M. Wang (voucher number “ SCAU HA11 ”, “ SCAU HA12 ”, “ SCAU HA13 ”) , 2 males: CHINA, Hubei province, Shennongjia National Park , 13-VIII-2018 (voucher number “ SCAU HA34 ”, “ SCAU HA35 ”) , 1 female: CHINA, Guangdong province, Shaoguan city, Ruyuan county , altitude 500m, 22-IX-2018, leg. Z.P. Miu & F.H. Wei (voucher number “ SCAU HA15 ”) , 1 female: CHINA, Guizhou province, Tongren city, Shiqian county, Fodingshan Natural Reserve , altitude 617m, 03- Ⅴ -2018 (voucher number “ SCAU HA05 ”) .

Diagnosis. The new species is morphologically resembled H. pseudobutleri , but the wings ground colour is darker; subapical ventral section of valvae semi-membranous (sclerotized in pseudobutleri ); valvae slender (broad in pseudobutleri ); ampullae slender and elongated (short in pseudobutleri ); ductus shorter and thicker (slender in pseudobutleri ); bursa bigger (smaller and rounded in pseudobutleri ). However, the Maximum Likelihood (ML) tree of Hamodes ( Fig. 9 ) shows that the new species is most closely related to H. butleri which is unexpected. Within the genus, nine individuals of H. zhipengi are recovered in a clade with strong support (UFBoot= 98). The pairwise Kimura 2-parameter (K2P) distances between the species in Hamodes range from 4.96% to 9.95%, and the distances between H. zhipengi and relatives, H. hainana , H. pseudobutleri and H. butleri are 5.21%, 5.27% and 6.37%, respectively (Table. 2).

Description. Male ( Fig. 1 ). Length of forewing 11.8 mm.Antennae filiform, dark brown; labial palpus brownish; thorax brown, tegulae brown; abdomen dorsally brown in 1 st- 4 th segments, black in 5 th- 8 th segments. Forewing ground colour fuscous brown, scattered with tiny black scales; outer marginal area darker than inner area; antemedial line blackish-grey straight and irregular, extending from costa to 1A+2A; medial line black and obscure, extending from costa to vein R 5 and followed by a crescent-like reniform stigma; orbicular stigma black, dot-like; postmedial line black and obscure, extending from costa to vein R 4; submarginal line blackish brown defined with fine ochreous-whitish line at inner side. Hindwing ground colour same as forewing, median line black extending from Rs vein to middle of anal margin, defined by ochreous-whitish inner stripe, discal spot fine, bar-shaped, dark grey.

Male genitalia ( Fig. 5 ). Uncus slender and hook-shaped; tegumen narrow; valvae long and narrow, subapical ventral semi-membranous; ampullae slender and hook-shaped, left slightly shorter than right; costa sclerotized; saccus small; aedeagus thick and long, with sclerotized lamellae.

Female ( Fig. 2 ). Wingspan 11.2 mm. Compared with the male adult, the ground colour of the wings is lighter, fasciae and stigmata are dimmer; abdomen dorsally brown.

Female genitalia ( Fig. 6 ). Anal papillae thick and long; anterior and posterior apophyses slender; ductus bursae long, flattened tubular, dilated anteriorly, partly strongly and smoothly sclerotised; appendix bursae membranous, slightly helicoidal; corpus bursae membranous, finely and irregularly scobinate.

Distribution. China: Guangdong, Hubei, Guizhou.

Etymology. This species is named after Mr. Zhipeng Miu in honour of his contribution to the Department of Entomology, South China Agricultural University.
