Notes. Coeliccia yamasakii was originally described from Chonburi Province of Thailand based on male specimens ( Asahina 1984) and later was recorded from Phu Quoc Island of Vietnam ( Bui 2007) and southwestern Cambodia ( Kosterin & Holden 2011). We describe the female of C. yamasakii although photos of the female (habitus in nature) were previously provided by Bui (2007: p. 15), Kompier (2017) and Kosterin & Holden (2011: Fig. 4 View FIGURE 4 ).

Postclypeus entirely black. Top of first and second segments of antennae yellowish, remainder black.
