Psilota xanthostoma Young  sp. nov.

(Species plate: Fig. 38View FIGURE 38; Map: Fig. 66AView FIGURE 66)

Diagnosis: Face and gena entirely yellowish-orange, frons black. Fore and mid legs entirely yellowish-orange. Thorax black. Abdomen orangeish-brown. Hind leg simple. Body length: 5.1 mm.

Description: MALE: unknown.

FEMALE: Head: Vertex frons and occiput black, face and gena yellowish-orange. Head shining, free of pollinosity. Face and eye sparsely yellow pilose. Vertex yellow pilose. Antenna entirely yellowish-orange. Thorax: Thorax black, shining, pollinosity free. Fore and mid leg entirely yellowish-orange. Hind femur and tibia orangeishbrown, hind tarsomeres yellow. Hind femur unmodified, with only a few weak, black setulae apicoventrally. Thorax entirely yellow pilose. Halter yellow. Calypter pale. Wing colourless, entirely microtrichose.

Etymology: The specific epithet ‘ xanthostoma  ’ consists of xantho, derived from the Latin “xanthous”, meaning “yellow”, and stoma, meaning “hole”, or mouth. This is in reference to the yellow face, gena, and “mouth” area of P. xanthostoma  sp. nov.

Specimens examined: HOLOTYPE: AUSTRALIA: Queensland: Carnarvon National Park, Mount Moffatt summit, 1097m, - 25.059722S 148.043889E, 29.xi.1997, J. Skevington and C. Lambkin, T221267 (1♀, QM).GoogleMaps 

Discussion: This species is known from a single female specimen, collected on Mt. Moffat in Carnarvon National park, Queensland. Although no male has been collected, a fragment of the DNA barcode was successfully obtained from the holotype, so if a male is collected in the future it can be confidently matched to the holotype using DNA evidence. The barcode data extracted from the holotype is publicly available on the BOLD website (Process ID: SYRAU381-18), as detailed above in the Materials and methods section.
