- Ambrosiophilus atratus Hulcr, Jiri, 2009, Zootaxa 2204: 22-23.
Description
Compared to (unspecified) “ type ” in BMNH.
Diagnosis
Diagnosis: Superficially resembles some Anisandrus spp., but has no pronotal tuft, and the antennae are not flat and type1, but oblique, type3. Conspicuous punctures on pronotum. It differs from most other Ambrosiophilus by having a less steep elytral declivity with virtually no tubercles, but the declivital stria 1 is impressed as in most Ambrosiophilus. Length: 3.0– 3.2 mm.
Discussion
Discussion. In a Bayesian multi-gene phylogeny (Cognato et al., in prep.) the species falls within the Ambrosiophilus clade with 100 % posterior probability. Superficially it resembles Ambrosiodmus, but it has key Ambrosiophilus characters. The species is transferred to the latter genus based on the absence of pronotal discal asperities and the overall shape of pronotum, which is not globular but has a flat disc.
Biology and Ecology
Biology: The species is native to temperate and subtropical East Asia and has been recently introduced to North America (Rabaglia et al.2006). The species does not parasitize other ambrosia beetle fungal gardens; each individual female creates her own independent gallery.
