Pseudanostirus tigrinus (Fall, 1901) comb. nov.

Distribution.

Native to North America. Previously known only from the United States, where the species is known from areas near Lake Tahoe in California ( Fall 1901). CNC has additional specimens collected in northern Oregon and near Lake Tahoe in Nevada.

Canadian record

(DNA barcoded specimen). British Columbia: Gulf Islands National Park Reserve, 30-May-2014 to 08-Jun-2014 (1 ex, CBG).

Additional Canadian record.

British Columbia: Parksville, 11-Apr-2018 (1 ex, CNC).

Diagnostic information

(based on Brown 1936). Body length 9.0-11.2 mm. Antennae with antennomeres 3 and 5 of equal length. Pronotum black, with pubescence pale except for two to circular patches of dark setae on each side. Elytra red-brown with pale setae, with band of darker setae surrounding scutellar shield and three angulate transverse bands of dark setae extending from suture to epipleura.

Bionomic notes.

Pseudanostirus tigrinus has been collected by beating Pseudotsuga Carrière on a grassy hillside with Quercus garryana Douglas ex Hook. trees. Other specimens have been collected in Malaise and funnel traps also in semi-open woodland with Arbutus L. and Pseudotsuga trees in warm-summer Mediterranean climate areas. The barcoded specimen was collected with a Malaise trap in a coastal mixed forest.

Comments.

This species was described as Corymbites tigrinus Fall, 1901. Brown (1936) placed this species in Ludius Berthold, 1827 as Ludius tigrinus (Fall, 1901), part of the L. triundulatus species group. Lane (1948) found that Ludius Eschscholtz, 1829 was a synonym of Elater Linnaeus, 1758 and transferred all North American Ludius to Ctenicera Latreille, 1829. Johnson (2002) indicated that all species of Brown’s triundulatus group should be transferred to Pseudanostirus but did not formally present any new combinations. This combination has not been used previously in the scientific literature. Therefore the resulting combination Pseudanostirus tigrinus (Fall, 1901) is used here for the first time.

Pseudanostirus tigrinus is similar to P. nebraskensis (Bland, 1863). Its independent placement in a separate BIN cluster supports the validity of P. tigrinus .
