Netelia thoracica (Woldstedt, 1880)

= syn. Netelia ahngeri (Kokujev, 1906)

This species belongs to the subgenus Paropheltes : the occipital carina is absent, the scutellum has the lateral carina absent or weak, the areolet is usually closed by vein 3rs-m and the male has longer parameres, lacking curved ‘brace’ across internal surface (BROAD, 2012). N. thoracica has many black markings: the head with the stemmaticum, the mesoscutum (except for the central part) and the lower part of the mesopleuron are black. Its apical tergites are also blackish. The hind tarsi are white. Its temples are slightly narrowed behind the eyes (DELRIO, 1975). This is a genuinely rare species, which could be partly coastal. Orthosia incerta (Hufnagel, 1766) ( Lepidoptera : Noctuidae ) is the only known host ( MEYER, 1929).

First report for the Netherlands; unreported in Belgium.
