Genus Tetrichina Chang et Chen, 2020

Tetrichina Chang et Chen in CHANG et al. 2020 b: 39 . Type species: Tetrichina trihamulata Chang et Chen, 2020 , by original designation.

Lunatissus Meng, Qin et Wang in ZHANG et al. 2020: 496, syn. n. Type species: Lunatissus brevis Che, Zhang et Wang, 2020, by original designation.

Notes. The presence of the peculiar moon-shaped processes of the dorsolateral lobes of the phallobase and the distinct process below the neck of capitulum of style in the species of Tetrichina and Lunatissus ( CHANG et al. 2020 b, figs 35, 38, ZHANG et al. 2020, figs 222e, 222h, 223e, 223h) leave no doubt about the identity of these genera; therefore, their subjective synonymy is hereby proposed. According to the structure of the phallobase Tetrichina is closely related to the monotypical genus Yangissus Chen, Zhang et Chang, 2014 known from Guizhou ( CHEN et al. 2014), but the latter is well distinguished by the presence of furcate ventral aedeagal hooks ( CHEN et al. 2014, fig. 2-82M). The genus Tetrichina is apparently endemic to Hainan Island.

The date of publication of the work of CHANG et al. (2020 b) is indicated in the first page of the article as 6th August, 2020. Thus, Tetrichina has priority over Lunatissus.

A comparison of the drawings of the male genitalia of Tetrichina and Lunatissus species in the original publications of CHANG et al. (2020 b), WANG et al. (2020), and ZHANG et al. (2020) revealed the synonymies listed below.
