Parallelomma paridis Hering, 1923
Nomenclature
-
Subfamily: DelininaeGenus: Parallelomma
SUMMARY
According to Collin (1958)[1] the third antennal joint is darkened (clear yellow in P. vittatum) and the terminal bristle on the palps is stronger than the vibrissae (not as strong in P. vittatum). Hackman (1957)[2] illustrates paler markings on the thoracic dorsum which Nelson (1990)[3] confirms were present in his reared specimens, but cautions that teneral P. vittatum also showed similar markings. Nelson (1990)[3] suggests that the most reliable way of distinguishing the two was to measure the terminal bristle on the palps which was 0.38-0.49 mm in P. paridis compared to 0.24-0.38 mm in P. vittatum. Wing length: ♀ 4.4 mm (1).
