Ambrosiophilus wilderi (Beeson) comb. nov.

Xyleborus wilderi Beeson, 1929: 235 .

Ambrosiodmus wilderi (Beeson) : Wood & Bright 1992: 681.

Xyleborus upoluensis Schedl, 1951: 152 . Synonymy: Beaver 1976: 542.

Hulcr & Cognato (2009) described the genus Ambrosiophilus for species of Ambrosiodmus Hopkins and Xyleborus Eichhoff that had a flat pronotal disc that lacked asperities, an antennal club type 3 (see Hulcr et al. 2007) that is flattened and rounded, and a steep declivity. Beaver (1976) reports that galleries of this species were closely associated with galleries of Beaverium swezeyi (Beeson) , indicating possible mycocleptoparasitism, an ecological characteristic of Ambrosiophilus ( Hulcr & Cognato 2010) . Wood & Bright (1992) list this species in Ambrosiodmus . The species has the generic characters of Ambrosiophilus and is here transferred to that genus.

Beeson (1929) described X. wilderi based on specimens from Fagasa and Pago Pago on Tutuila. X. upoluensis Schedl (1951a) from Upolu was synonymized with wilderi by Beaver (1976). This species is endemic to the Samoan islands and Fiji.
