Trichrysis chamchuensis Wiśniowski & Nguyen in Wiśniowski et al., 2020

( Fig. 1 )

Material examined. 1♀, VIETNAM; Cao Bang, Nguyen Binh, Quang Thanh / Hoai Khao , Phia Oac-Phia Den NP / 879 m a.s.l.; 10.v.2021 / 22°36′39″N 105°54′40″E / [leg.] NTPL, NQC, TTN ( IEBR).

Remarks. In our previous article, Trichrysis chamchuensis was described based on type specimens from Cham Chu NR, Ham Yen, Tuyen Quang, Vietnam, but mentioned that 'all sterna in both the holotype and paratype are partly destroyed ventrally, and therefore black spots cannot be described ’ ( Wiśniowski et al. 2020). During the present study, an intact female of this species was collected and their black spots on S2 were studied: they are almost triangle-shaped and fused medially ( Fig. 1 ).
