Figures 3–5

Material examined. Holotype: Tasmania, Tahune Forest Reserve, Pine Tk , Lagarostrobos franklanii , 17 Feb 1988. Five paratypes: same data as holotype.

Description of female. Coloration (after ca 5 years in alcohol). Head dark brown. Median epicranial suture black. Antenna brown, maxillary palp brown, apical segment dark brown. Eyes black. Thorax and legs dark brown, tarsi brown. Abdomen dorsally dark brown, cream ventrally, terminal segments dark brown. Freshly killed specimens bright iridescent pink on vertex, dorsal surfaces of thorax and abdomen, and femora. This coloration fades in alcohol.

Morphology. IO:D = 2.3. Eyes ovoid, dorsal margin in line with top of vertex. Antenna complete with 26 flagellar segments (paratype).Distal margin of labrum with anterior row of 5 trichoid sensilla and posterior row of 4 trichoid sensilla. Vertex fairly sharp, postclypeus flattened. Clypeal shelf broad. Lacinia bifid, lateral projection larger than median. Ocelli absent. Apical segment of maxillary palp broad, second segment with large sensillum. Reticulate pattern on vertex and postclypeus barely visible. Head, including eyes, and thorax bearing scattered setae of differing lengths. Tibiae with 2 apical spurs. Hind tibia with 4 (paratype) long fine setae on outer margin, length about 3 to 4 times width of tibia. A single long, fine seta of similar length on middle of mid tibia. Ctenidiobothria absent. Tarsi 3-segmented, claw lacking subapical denticle.Pulvillus fine, apically broadened. Abdomen with tergites well sclerotised, each bearing two incipient rows of long setae. Sternites not sclerotised, bearing dense shorter setae. Epiproct (fig. 3) simple, setose. Paraproct (fig. 3) lacking trichobothria, with strong posterior spine and ventral sclerotised bar. Subgenital plate (fig. 4) simple, setose, with broad triangular pigmented area. Gonapophyses (fig. 5) with large setose external valve, and sclerotised dorsal valve remnant. Spermathecal duct present, parietal glands apparently absent.

Male. Unknown.

Remarks. This rare species, collected only from huon pine in southern Tasmania, differs from all other known species in the genus by the coloration (fresh material). Lepinotus huoni also differs from Lepinotus tasmaniensis and Lepinotus stoneae Smithers (NSW) by the absence of reticulated wings and parietal glands.

Etymology. Named for the French explorer, Jean-Michel Huon de Kermadec.
