bupariorbis
sp. nov.
ETYMOLOGY: The specific epithet derived from the Latin bu, par, and orbis, meaning ‘‘pair of large circles’’ ( Brown, 1956), and refers to large paired circles of the female epigynal region.
DIAGNOSIS: This species can be easily distinguished by the elongate lateral process of the male palp, which is bent retrolaterally, ending with a curved, caplike distal tip (fig. 67A, B). Dorsal scute of both sexes small and covering only 1/2–2/3 of the abdomen length (fig. 66A, D). The female epigynum is characterized by a pair of large epigynal atriums positioned posteriorly to a short convoluted duct (figs. 66I, 67F).
MALE (PBI_OON 00021970, figs. 66A–C, G–H, 67A–E). Total length 1.43. CEPHALO- THORAX: Carapacepale orange, broadly Fig. 66. Ischnothyreus bupariorbis, sp. nov.Holotype male (PBI_OON 00021970): A.habitus, dorsal view; B.habitus, ventral view; C.habitus, lateral view; G.carapace, anterior view; H.sternum, ventral view. Allotype female (PBI_OON 00025760): D.habitus, dorsal view; E.habitus, ventral view; F.habitus, lateral view; I.epigynum, ventral view. oval in dorsal view, pars cephalica strongly elevated in lateral view, anteriorly narrowed to 0.49 times its maximum width or less, anterolateral corners without extension or projections, surface of elevated portion of pars cephalica smooth, sides finely reticulate. Clypeusmargin unmodified, straight in front view, low, ALE separated from edge of carapace by less than their radius; setae dark. Eyes:ALE largest, ALE circular, PME oval, PLE oval; posterior eye row straight from above; ALE touching, ALE-PLE touching. Sternumlonger than wide, pale orange, uniform; setae dark, evenly scattered. Chelicerae pale orange, endites, and labium dark red brown. Chelicerae slightly divergent, anterior face unmodified; promargin with one larger denticle; fang shape normal, with small basal process; setae dark. Labium elongated hexagon, not fused to sternum, anterior margin indented at middle, more sclerotized than sternum, with six or more setae on anterior margin. Endites anteromedian tip with one strong, broad toothlike projection, much more heavily sclerotized than sternum. AB- DOMEN: Ovoid; dorsum soft portions white. Book lung covers elliptical. Dorsal scutum pale orange, covering more than 3/4 of abdomen, more than 1/2 to most of abdomen width, middle surface smooth, sides smooth. Epigastric scutum small lateral sclerites present. Postepigastric scutum pale orange, covering about 1/2 of abdominal length. Dorsum, epigastric area, and postepigastric area setae dark. LEGS: Pale orange, without color pattern; patella plus tibia I shorter than carapace. Leg spination: femora: I p0-1-1; II p0-1-0; tibiae: I, II p2-2-0; v2-2-0; metatarsi: I, II p1-1-0; v1-1-0. GENITALIA: Palp proximal segments dark red-brown; embolus dark; femur shorter than trochanter; patella about as long as femur; cymbium dark red-brown; bulb dark red-brown, more than two times as long as cymbium, stout; embolic region with enlarged and complex processes, obtusely bent, lateral process bent retrolaterally, distal tip caplike (fig. 67A, B).

Allotype female (PBI_OON 00025760): F.epigynum, ventral view. Scale lines 5 0.1 mm. Map 12. Map of southern Queensland and northern New South Wales showing recorded distributions of Ischnothyreus bupariorbis()and I. rixi( m). FEMALE (PBI_OON 25760, figs. 66D–F, I, 67F). Total length 1.53. CEPHALOTHO- RAX: Carapacepars cephalica slightly elevated in lateral view. Chelicerae, endites, and labium pale orange. ABDOMEN: Dorsal scutum covering about 1/2 of abdomen, between 1/4 and 1/2 abdomen width. Postepigastric scutum widely hexagonal, covering about 1/3 of the abdominal length. LEGS: Leg spination: femora: I p0-1-1; II p0-1-0; tibiae: I, II p2-2-0; v2-2-0; metatarsi: I, II p1- 1-0; v1-1-0. GENITALIA: Ventral view: epigynal atrium paired, large, circular, sclerotization uniform; convoluted duct very short, thicker than apodemes (figs. 66I, 67F).
