Lectotype â™€ [designated by LaBerge, in Webb 1980: 116]. USA, Illinois, Carlinville, 21 July 1891, by C. Robertson [INHS no. 11111]
Halictus cephalotes Dalla Torre, 1896: 57. [new name for H. cephalicus Robertson]
This is the type species for the genus-group Paralictus.
The DNA Barcode Index Number (BIN) for this species has not been assigned.
â™€ body length: 4.76–4.88 mm; head length: 1.44–1.73 mm; head width: 1.82–1.85 mm; forewing length: 3.90–4.03 mm
â™‚ body length: 5.80 mm; head length: 1.38–1.58 mm; head width: 1.49–1.70 mm; forewing length: 4.03 mm
This species is a social parasite, and hosts include other Dialictus; it has been found at nesting sites of Lasioglossum zephyrum (Robertson 1901, 1926). The Ontario records for this species reported by MacKay and Knerer (1979) were misidentifed specimens of L. lionotum (Gibbs 2010), another social parasite. Thus, no Canadian specimens of L. cephalotes are known, but because it has been found in adjacent arease of the United States, and because presumed host species, L. zephyrum, is widespread in Canada it is likely that it occurs in southern Ontario.
