[Key locator: Key to Group B species, couplet 16’] Heteragrion valgum: Donnelly 1992: 56–57 (key to species, couplet 5; description and diagnosis of ♁ and ♀ from Panama; comparison with H. mitratum and H. erythrogastrum ; figs. 5.3, 5.8, 5.10, 5.15);— Suhling 1999: 51 (recorded in El Valle, Panama);— Garrison et al. 2010: 88 (list of Heteragrion species);— Molinar et al. 2015: 87 (list of species from Panama);— Stand-Pérez et al. 2019: 92–93, 110 (table of information; key to species, ♁ in couplet 14; remarks; figs. 6d, 11g –i, 20).

Material examined. 1♁ (PARATYPE) PANAMA, Panama, Cerro Azul , 2.vii.1970, (ca. 700m asl), E.S. Morton leg., FAAL ; 1♁ COLOMBIA, Chocó Department, Acandí Municipality, Vereda Rufino, Quebrada Capitancito , 10.xii.2005, (8.5787, -77.3109, 30m asl), C. Botero leg., UARC GoogleMaps ; 5♁♁ same data, but ANDES–E GoogleMaps .

Known distribution. Panama and Northwestern Colombia.

Diagnosis and remarks. This species is assessed as Data Deficient in the IUCN Red List, as it occurs at a limited number of localities and has been collected only once recently ( González-Soriano & Guzmán Ojeda 2021b). In cercus morphology, H. valgum is close to H. chrysops , H. eboratum , H. calendulum and H. alienum , with which it shares the MP ridge bearing only small teeth and not partially covering ML. This species can be separated from these and the remainder of Group B species by the following character combination: ridge above ML consisting of a patch of small denticles, not in a single row ( Figs. 67d–e View FIGURE 67 ); ML apex acute ( Figs. 67d–e View FIGURE 67 ).
