Phaea quadrimaculata Wappes & Santos-Silva, 2021 ( Fig. 7 )

Phaea quadrimaculata Wappes & Santos-Silva, 2021: 2 .

Remarks: This species was described based on a single female ( Fig. 7F ) from Mexico (Chiapas). We examined a male of the species, which is quite similar to the female in general appearance.It differs from the holotype by the head and most of prothorax ( Fig. 7-E ) yellower (orangish-brown in the holotype),and scape ( Fig.7-E ) black only apically (entirely black in the holotype). Furthermore,the abdominal ventrites 1-4 in male ( Fig. 7C ) are distinctly elevated toward the apex, while they are flattened in the holotype ( Fig. 7F ). Such sexual dimorphism, apparently, has never been reported in Phaea . However,it also occurs in some other species such as in P. lingafelteri Heffern, Santos-Silva & Nascimento, 2018 . The chromatic variation, especially of the scape, also occurs in P. lingafelteri .

Material examined: MEXICO, Oaxaca (new state record): 16 mi. NW Tehuantepec, 1 male, 22. VI.1966, J.B. Karren leg. ( LGBC).
