Ectopsocus coyae sp. nov.

Figures 108–11

Material examined. Holotype: Tasmania, Rocky Cape National Park, Sisters Beach Road , wet scrub, 25 Oct 1986.

Description of female. Coloration (after ca 7 years in alcohol). Head brown with the following dark brown: markings dorsal to eyes, along back of vertex and on each side of black median epicranial suture; broad patch on frons, between ocelli and dark epistomal suture; postclypeal striae and labrum. Eyes black. Anteclypeus colourless. Fore wing (fig. 108), hind wing (fig. 108), thorax and legs brown, thoracic sutures dark brown. Abdomen buff, terminal segments brown.

Morphology. IO:D = 3.5. Median epicranial suture not distinct on anterior half of vertex. Ocelli absent. Distal margin of labrum with 5 sensilla. Distinct row of 6 trichoid sensilla on anterior margin of outer surface of labrum, each lateral sensillum much smaller than the four median sensilla. Epistomal suture present, clypeal shelf absent. Lacinia apically bifid, apex of outer projection bidentate. Vertex with vague suggestion of being sculptured with large polygonal-shaped cells. Flagellar segments with two placoids near base of f 1, one at apices of f 4, f 6 and f 10; placoids of f 6 and f 10 with a long slender filament. Fore wing and hind wing (fig. 108) as small setose rudimentary flaps, a small spiculate dome located on apical half of fore wing and a few setae on posterior margin of hind wing. Epiproct (fig. 109): basally sclerotised, bearing setae each side of median line; posterior margin bearing 2 large setae (one missing in preparation) and a row of minute setae. Paraproct (fig. 109) with 3–4 trichobothria and 1 seta not in rosette. Posterior margin bearing group of setae and a single spine, median region bearing a row of long setae. Subgenital plate (fig. 110): pair of apical sclerotised lobes, each bearing 7 setae; small median region between lobes not sclerotised; well developed row of preapical setae; pigment band not divided into anteriorly diverging arms. Gonapophyses (fig. 111): external valve well sclerotised, setose over apical third; dorsal valve broad, membranous, with spiculate apex; ventral valve sclerotised, apex spiculate. Spermathecal plate (fig. 111) membranous, rounded, containing numerous granules.

Male. Unknown.

Remarks. This species is similar to Ectopsocus edwardsi (below) in details of coloration and genitalia. The lobes of the subgenital plate are somewhat angular, and the apices bluntly pointed compared to the shallow rounded lobes of E. edwardsi . The setae are more numerous on the external valve of the gonapophyses of E. coyae . The wings of the two species differ considerably. The small spiculate dome on the fore wing and the setae on the hind wing (fig. 108) are absent in E. edwardsi .

Etymology. Named for Dr Robyn Coy, in recognition of her contribution to the knowledge of Tasmanian rainforest invertebrates.
