A small lateral process bends backward on the retrolateral side of the embolic region (fig. 50A, B, E). The female epigynal region is equally simple, and consists of a small triangular extention pointing anteriorly and positioned at the base of a long convoluted duct (figs. 49I, 50F).  MALE (PBI_OON 5883, figs. 49A–C, G– H, 50A–E). Total length 1.63. CEPHALO- THORAX: Carapaceorange-brown, broadly 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, 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 oval; posterior eye row straight from above; ALE touching, ALE- PLE touching. Sternumlonger than wide, pale orange, uniform; setae dark, evenly scattered. Labium and endites dark red brown, chelicerae pale. Chelicerae slightly divergent, anterior face unmodified; promargin with one or two slightly larger denticles; fang shape normal, without prominent basal process; 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 anteromedian tip with one strong, toothlike projection, much more heavily sclerotized than sternum. AB- DOMEN: Ovoid; dorsum soft portions white. Book lung covers elliptical. Dorsal scutum pale orange, covering 1/2 to 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 2/3 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 p0-2-0; 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 one to two times as long as trochanter; patella about as long as femur; cymbium dark red-brown; bulb dark red-brown, 1 to 1.5 times as long as cymbium, stout; embolic region stout, broad, obtusely bent, small lateral process bent backward on retrolateral side (fig. 50A, B, E). FEMALE (PBI_OON 00005854, figs. 49D– F, I, 50F). Total length 1.90. CEPHALO- THORAX: Carapacepale orange, pars cephalica slightly elevated in lateral view, surface of elevated portion of pars cephalica finely reticulate. Clypeusstraight in front view. Chelicerae, endites, and labium pale orange. ABDOMEN: Dorsal scutum between 1/4 and 1/2 abdomen width. Postepigastric scutum widely hexagonal, only around epigastric furrow. LEGS: Leg spination: femora: I p0-1-1; II p0-2-0; tibiae: I, II p2-2-0; v2-2-0; metatarsi: I, II p1-1-0; v1-1-0. GENITALIA: Ventral view: epigynal region simple, epigynal atrium not clearly visible but with slight depression, posterior portion of depression with small triangular extention pointing anteriorly; convoluted duct thicker than apodemes, long (figs. 49I, 50F).  Fig. 49.  Ischnothyreus eacham, sp. nov.Holotype male (PBI_OON 00005883): A.habitus, dorsal view; B.habitus, ventral view; C.habitus, lateral view; G.carapace, anterior view; H.sternum, ventral view.
