Proportional ratios: LSI/HMP—0.92; LSI/WT1_AP—1.93; WT1_AP / WT1_BA—2.81. Genitalia. Aedeagus with rounded apex; parameral spine and digit distinctly surpassing aedeagus apex ( Figs 58, 59 View FIGURES 56–63 ).

Remarks. This species was for a long time confused with Polistes parvulus described by Fabricius (1804). It was recognized as a “ Polybia ” by Bequaert (1944: 287) who considered it a variety of P. occidentalis , i.e. as P. occidentalis var. parvula (Fabricius) . Richards (1951) considered that Bequaert’s variety should be indeed treated as a distinct species, but with authorship still attributed to Fabricius, as Polybia parvula (Fabricius) . However, Richards (1970) reported that Van der Vecht informed him that Fabricius’ species was an Eumeninae. Thus, Richards (1970) created for the social species the new name Polybia parvulina . It has been recorded from Costa Rica, Colombia, Guyana, Venezuela and Brazil (Amazonas, Amapá and Pará; see also Silveira et al. 2019).
There are only two records of nests mentioned by Richards (1978), having three and four combs. We examined only one nest at MPEG, which has a brown main color with some light brown spots; three combs; cell diameter ca. 3 mm; comb with the largest diameter ca. 3.5 cm.
