Comments. Latineosus sigillatus can be characterized by the relatively large size (male body ca. 4 mm, female ca. 5 mm); with characteristic blackish marks on abdominal terga, presence of vestiges of posterolateral projections on abdominal segments IV–VI, male subgenital plate broadly emarginated posteriorly, ratio of forceps length/ subbasal width 8.9 (adapted from Molineri 2014). Variations related to color pattern were observed in specimens from Rondônia. It was observed that the pronotum does not present a medial T-shaped black mark, abdomen without blackish median marks on terga VII–IX, and head without paired sublateral black marks near hind margin.
