Material examined. 1♁ MEXICO, Oaxaca, mountain road to Tuxtepec , 27.viii.1959, (545 m asl), G.H. & A.F. Beatty leg., ABMM ; 1♁ Veracruz, stream near Playa Escondida , 9–13.viii.1982, (18.5666, -95.0666), R.W. Garrison leg., ABMM (head missing) GoogleMaps ; 1♁ COSTA RICA, Horquetas , 28.v.2013, (10.2836, -84.0468, 764m asl), A.C. Rivera leg., ECOEVO GoogleMaps .
Known distribution. Costa Rica and Mexico.
Diagnosis and remarks. Robust and remarkable species, mainly for the male head coloration ( Fig. 8a View FIGURE 8 ), which is paler than in any other species of the genus. According to Paulson (1981) and CBS (personal observation), the abdomen is entirey red, except for some yellowish on S1–2, as do some H. chrysops ( Williamson 1919) . Heteragrion albifrons can be separated from the remainder of Group B species by the following character combination: BP with a nearly straight margin ( Figs. 8c–e View FIGURE 8 ); portions of cercus all subequal in size ( Fig. 8d View FIGURE 8 ); ridge above ML straight, partially covering ML in dorsal and dorsolateral views, its apex forming a narrow tip ( Figs. 8c–e View FIGURE 8 ); ML quite broad, its apex rounded ( Fig. 8e View FIGURE 8 ); mouthparts and frons largely pale ( Fig. 8a View FIGURE 8 ). Morphologically close to H. tricellulare .
