Host Unknown. Male Described by Heinrich (1962 b, p. 730) in the original description, based on a single male that he designated as allotype. The other two known male specimens of the species are from Newfoundland and Labrador, recorded by Heinrich (1975, p. 774).

discussion
Comments Platylabus opaculus Thomson, 1888, is split in two subspecies, one with European distribution (the nominotypical subspecies), and the other occurring in the Nearctic (Heinrich 1962 b, p. 730). According to Heinrich (1962 b, p. 730), the only difference between the two is the colour of the legs, which are entirely black in Platylabus opaculus opaculus and rufous in Platylabus opaculus americanus. The records from Massachusetts are from BugGuide and identified by Carlson (2010 b) as Platylabus opaculus. However, these have not been recorded in any paper or catalogue (see Yu et al. 2016). The new record for North Carolina is based on a female specimen found at the FSCA that Townes identified as Platylabus opaculus americanus in 1967, which DDP double checked, confirming Townes’ identification. The record has never been reported in any paper or catalogue (cf. Yu et al. 2016), and apparently Heinrich (1975) was not aware of it since no mention of it appears in his paper. The record of Platylabus opaculus americanus for North Carolina also marks the southernmost distributional record for the subspecies and the first for the south-eastern United States (Figure 22 b).
