(Figures 1 K, 3 I, 9 A–C) <i>Type material</i> <i>Holotype.</i> &amp;male;, Thailand, Krabi Province, Khao Panom Bencha National Park, near Huay To Waterfalls, 220 m, rainforest, 22 July 2005. leg. P.J. Schwendinger (MHNG, TH–05 <i>/</i> 10). <i>Paratype.</i> One &amp;male;, data as holotype (MHNG, TH–05 <i>/</i> 10). <i>Diagnosis</i> <i>Sesieutes aberrans</i> sp. nov. is recognized by the very broad base of the conductor (Figure 9B,C), a feature that easily distinguishes it from its congeners. <i>Etymology</i> The specific epithet is a Latinized adjective in relation to the peculiar morphology of the male palp, which greatly deviates from other members of the genus. <i>Description</i> <i>Male</i> (holotype). Total length 5.68; prosoma 2.64 long, 1.84 wide; opisthosoma 3.00 long, 1.62 wide. Leg measurements: leg I 7.26 (1.98, 2.64, 1.52, 1.12); II 6.20 (1.66, 2.24, 1.30, 1.00); III 5.26 (1.52, 1.50, 1.32, 0.90); IV 8.06 (2.12, 2.50, 2.24, 1.18). Leg spination. Leg I: Fe p–1, Ti v–2–2 –2–2–2–2, Mt v–2–2 –2–2–2; leg II: Ti v–2–2 –2–2– 2–2–2, Mt v–2–2 –2–2; leg III: Ti p–1 v–1–1 –1–1 r–1, Mt p–1 v–1–1 r–1; leg IV: Fe d–1, Ti v–2–1 –1–2 r–1, Mt p–1, v–1–21 –1, r–1–1. <i>Pattern and coloration</i> (Figure 1K). Carapace brown; in profile highest mid distance between PME and fovea; integument smooth and shiny, with few nodules situated along peripheral margin; fovea indistinct, replaced by large, circular depression; chelicerae, labium and gnathocoxae brown; sternum dark brown; legs bicolored, coxae to femora orange, patellae to tibia yellow, metatarsi and tarsi pale yellow. Opisthosoma elongate-ovoid, relatively narrowed; dorsum entirely covered with dorsal scutum; venter pale; dorsal scutum ovoid, heavily sclerotized, occupying entire length of opisthosoma; epigastric scutum heavily sclerotized, protruding anteriorly, forming ring collars, tightly fused with dorsal scutum. <i>Palp</i> (Figures 3I, 9 A–C). Palpal tibia with small, triangular prolateral excrescence; proximal RTA truncated, with membranous area situated apically in ventral view, strongly elevated, represented by triangular projection with membranous anterior surface in prolateral view; distal RTA heavily sclerotized, triangular, relatively broad at base, apex slender, sharply pointed; tegulum greatly expanded posteriorly, with deep posterior excavation where embolic base originating; conductor very broad basally, gradually tapering anteriorly, originating on meso-retrolateral side of tegulum; tegular apophysis spiniform, hyaline, originating near base of conductor; embolus ribbon-shaped, gradually tapering distally, apex filiform. <i>Female.</i> Unknown. <i>Natural history</i> Types of <i>S. aberrans</i> sp. nov. were collected in coastal rainforest. <i>Distribution</i> Known only from the type locality in southern Thailand.
