Superbus, false summit, 28.23333 °S, 152.46670 °E, 1200 m( 12 Mar–13 June 1990 T.B. Churchill, R.J. Raven), deposited in QM( ³ holotype: QM S16568, PBI_OON 21959; ♀ allotype: QM S16568, PBI_ OON 5609).
ETYMOLOGY: The specific epithet is a noun in apposition.
DIAGNOSIS: This species can be easily recognized by the extremely elongate, obtusely bent embolic region of the male palp (fig. 73A, B) and the basal process of the fang consisting of numerous heavily sclerotized lobes (fig. 73C, D). The female possesses a heavily sclerotized circular epigynal atrium, which appears to be fused to the overhanging process and the horizontal sclerotization anterior to the epigynal atrium is less sclerotized than I. rixi, sp. nov.(figs. 72I, 73E).
MALE (PBI_OON 21959, fig. 72 A–C, G, H; paratype(PBI_OON 05631), fig. 73A–D). Total length 1.73. CEPHALOTHORAX: Carapacebrown, broadly oval in dorsal view, pars cephalica slightly elevated in lateral view, anteriorly narrowed to between 0.5 and 0.75 times its maximum width, anterolateral corners without extension or projections, surface of elevated portion of pars cephalica strongly reticulate, sides strongly reticulate. Clypeusmargin unmodified, curved downward 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 circular; posterior eye row straight from above; ALE touching, ALE-PLE touching. Sternumas long as wide, pale orange, uniform; setae dark, evenly scattered. Chelicerae, endites, and labium pale orange. Chelicerae slightly divergent, anterior face unmodified; promargin with one larger denticle; fang shape normal, basal process consisting of numerous heavily sclerotized lobes, anterior lobe with distal ridges; setae dark. Labium elongated hexagon, not fused to sternum, anterior margin indented at middle, same as sternum in sclerotization; with six or more setae on anterior margin. Endites distally not excavated, anteromedian tip with one strong, toothlike projection, same as sternum in sclerotization. ABDOMEN: Ovoid; dorsum soft portions pale orange. Book lung covers elliptical. Dorsal scutum brown, covering more than 3/4 of abdomen, no soft tissue visible from above, middle surface finely reticulate, sides finely reticulate. Epigastric scutum small lateral sclerites absent. Postepigastric scutum orange-brown, covering about 2/3 of abdominal length. Dorsum, epigastric area, and postepigastric area setae dark. LEGS: Orange-brown, without color pattern; patella plus tibia I shorter than carapace. Leg spination: femora: I p0-2-0; 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 redbrown; bulb dark red-brown, more than two times as long as cymbium, stout; embolic region extremely narrow and elongate, obtusely bent, tip rounded, transparent membranous tissues visible medially (fig. 73A, B). Fig. 72. Ischnothyreus pterodactyl, sp. nov.Holotype male (PBI_OON 00021959): A.habitus, dorsal view; B.habitus, ventral view; C.habitus, lateral view; G.carapace, anterior view; H.sternum, ventral view. Allotype female (PBI_OON 00005609): D.habitus, dorsal view; E.habitus, ventral view; F.habitus, lateral view; I.Epigynum, ventral view. Fig. 73. Ischnothyreus pterodactyl, sp. nov.Paratype male (PBI_OON 00005631): A.left palp, prolateral view; B.left palp, retrolateral view; C.left chelicerae, anterior view; D.left chelicerae, posterior view. Paratype female (PBI_OON 00005639): E.epigynum, ventral view. Scale lines 5 0.1 mm. FEMALE (PBI_OON 5609, fig. 72D–E, I; paratype(PBI_OON 5639), fig. 73E). Total length 1.98. CEPHALOTHORAX: Carapaceanteriorly narrowed to 0.49 times its maximum width or less. ABDOMEN: Dorsal scutum covering 1/2 to 3/4 of abdomen, more than 1/2 to most of abdomen width. Postepigastric scutum widely hexagonal, covering about 1/3 of the abdominal length. LEGS: Leg spination: femora: I p0-2-2; 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: strong horizontal scleriotization anterior to rounded epigynal atrium clearly joins posteriorly directed lateral apodemes; heavy sclerotization around epigynal atrium circular, thick; overhanging process slightly triangular, sides appear fused to postepigastric scutum; convoluted duct thicker than apodemes (figs. 72I, 73E).
