Squamosa brevisunca brevisunca Wu & Fang, 2009, Acta Zootaxonimica Sinica 34 (2): 237. Type locality China: Hainan. Holotype (by original designation): ♂ (IZCAS) [examined].

Squamosa svetlanae = Squamosa svetlanae Solovyev & Witt, 2009, syn. nov., Entomofauna, suppl. 16: 186. Type locality Nord-Vietnam: Mt. Fan-si-pan. Holotype (by original designation): ♂ (MWM/ ZSM) [examined].

Specimen examined.

1♂, China, Prov. Yunnan, Lvchun County, Mt. Huanglian, 27-31.VII.2018, leg. HL. Han, J. Wu, MR. Li, genit. prep. WuJ-091-1 (NEFU).

Diagnosis.

The nominate subspecies cannot be distinguished from S. brevisunca yunnanensis Wu & Fang, 2009 (Fig. 6 View Figures 1–12 ) externally but the morphology of male genitalia is diagnostic. In the male genitalia, the left process of juxta is long and the right process is finger-shaped apically in S. brevisunca brevisunca (Figs 17 View Figures 13–24 , 18 View Figures 13–24 ), whereas the left process of juxta is short and the right process is blunt apically, without the finger-shaped apex in S. brevisunca yunnanensis (Fig. 15 View Figures 13–24 ).

Distribution.

China (Hainan, Guangxi, Yunnan), Vietnam (Fig. 25 View Figure 25 ).

Bionomics.

We collected a single specimen in July at altitude about 1945 m a.s.l., with a light trap close to a broad-leaved forest with ferns and shrubs.

Remarks.

By examining the holotypes of S. brevisunca brevisunca (China: Hainan) and S. svetlanae (Vietnam: Mt. Fan-si-pan), we found that there are no significant differences in either the external appearance or the morphology of the male genitalia between them. In addition, we also collected a male specimen of the nominate subspecies from southern Yunnan, China, an area extremely close to the type locality of S. svetlanae , on the basis of which we establish the synonymy S. brevisunca brevisunca Wu & Fang, 2009 = S. svetlanae Solovyev & Witt, 2009 syn. nov. here.
