Diagnosis: May be differentiated from other Protus by the combination of the following features: lateral margins of DS with a yellow stripe going from carapace to area IV in abdomen, but without invading mesotergum ( Fig. 40A ); coxa IV with one yellow dot in lateral side ( Fig. 40B ); distal border of VP of the penis convex without median cleft and stylus with distal wattle not going to the base ( Fig. 41A–C ). Distribution: Solimões-Japurá moist forest in Amazonas department of Colombia , Southwest Amazon moist forest and Japurá-Solimões-Negro moist forest in Amazonas state of Brazil ( Fig. 30 ). Description of male ICN-Ao-381 (with extra figures from other specimens): Measurements: CL: 1.70, CW: 2.58, AL: 3.05, AW: 4.35, IOD: 0.72, FeIV: 14.62. Dorsum ( Fig. 40 ). DS beta-type and lenticular in lateral view, without remarkable ornamentation, only low, coloured tubercles in areas I and III. Anterior edge of dorsal scutum with protoglyphs slightly concave with lateral triangular borders. Ocularium low and with a few granules near the eyes. Mesotergum convex, higher at level of area II, scutal areas I and III armed with a pair of rounded tubercles, other areas unarmed. Posterior border and free tergites each containing a transverse row of minute granules, anal operculum with scattered granules. Venter. Coxae I–III triangular, transverse to main body axis, each with a longitudinal row of granules. Coxae II–IV connected by tubercular bridges. Coxa IV pentagonal, greatly developed, oriented obliquely, but almost parallel to the body axis. Stigmatic area T-shaped with stigmata large, unconcealed. Free sternites each with a row of granules. Chelicerae ( Fig. 41D, E ). Hand not swollen. Basichelicerite short, with well-marked bulla and uniformly granulated dorsally. Mesal margin of bulla with three setiferous tubercles, larger than dorsal ones. Posterior and ectal margins of bulla fringed with many tubercles. Movable finger of cheliceral hand with nine trapezoidal tubercles. Fixed finger with three triangular tubercles of different sizes. Pedipalps ( Fig. 41F–H ). Elongate trochanter, foliaceus femur, convex dorsally, with a dorsal row of seven setiferous tubercles and a ventral row of 14 setiferous tubercles. Tibia only slightly convex in the mesal side, with two ventro-marginal rows of small setae each side, mesal region three equally spaced large setae. Tarsus conical, with scattered dorsal setae and three well-marked ventral rows of subequal setae. Legs ( Fig. 40 ). Long and unarmed legs, femora straight. Coxa IV convex in dorsal view with few apical granules, no clavi inguines. Pectinate claws in legs II and IV in two rows. Tarsal counts: 7(3), 15(3), 11, 12/13 (from Roewer, 1928 ). Colour (in alcohol, Fig. 40 ). DS and coxae dark reddish-brown (44), with numerous two lateral stripes and two paramedian spots brilliant greenish-yellow (98) in each area I and III. Coxa IV with one spot of the same colour than stripes in DS. Trochanters vivid greenish-yellow (97) and the rest of podomeres brilliant yellow-green (116) and dark olive (108). Chelicerae and pedipalps deep orange (51) mottled in dark brown (59) Penis ( Fig. 41A–C ). Ventral plate rectangular elongate, with apical corners rounded, distal margin convex. Sub-distal lateral margin of VP with two pairs of MS-C, large, slender and conical. Two pairs of MS-D located in apical half of VP, MS-D1 twice longer than MS-D2 and closer to MS-C2, both MS-D straight and conical. One pair of MS-A basally in VP, straight, conical and as long as MS-D1. Two pairs of MS-E in apical portion of lateroventral surface and one pair of MS-B in the basal portion of ventral surface of VP. Ventral surface glabrous apically, two wide basal regions with microsetae type 1 (T1) near MS-B and invading truncus. Glans with dorsal process thin and acuminate, stylus with a reduced distal wattle with serrate part and without stylar barbs.
