Schwendinger (MHNG and CD). <i>Diagnosis</i>.— This species resembles <i>Sesieutes schwendingeri.</i> It is distinguishable by the smaller size, the absence of a round thoracic pit, the presence of an interrupted white ring around the abdomen, the different pattern of the venter and the larger distal tibial apophysis. <i>Description.</i> — MALE. Total length 4.70 mm. Carapace length 2.30 mm, width 1.90 mm, height at coxae II 0.70 mm, head width 1.20 mm, width eye group 0.80 mm; abdomen 2.50 mm long, 1.40 mm wide. Leg lengths: leg I 6.70 mm (2.10-2.20-1.70-0.70) leg II 6.25 mm (1.75-2.25-1.35-0.90), leg III 5.35 mm (1.50-1.75-1.30-0.80), leg IV 7.70 mm (2.10-2.60-2.15-0.85), palp 0.75-0.25-0.35- 0.85 mm. Carapace dark chestnut, with scabrous surface with darker radiating streaks, sternum orange, legs I and II dark, tibiae with yellow distal band, base and tip of metatarsi and tarsi yellow; femora III and IV dark, other leg segments yellow, patellae and tibiae with dark bands. Abdomen dorsally with scutum over half the length and width, halfway a white transverse band, interrupted in the middle, and a white area above the spinnerets; ventral surface predominantly dark, with one large post-genital white V, laterally a light oval spot at level of dorsal white band. Thoracic groove obsolete. Both eye rows faintly recurved when viewed from above, AER procurved when seen from front, AME half their d apart, connivent to laterals, PME slightly smaller, oval, separated by their d, more from laterals. Leg spination: femur I with 2-3 strong prolateral spines distally, other femora spineless, ventral surface of tibiae I and II flattened, with 8-9 pro- and 7 retroventral strong spines in leg I, 7 pro- and 6 retroventral spines in leg II, tibia III and IV with l-2v or 2-2v, 1 rl and an additional apical ventral pair in leg IV; metatarsus I with 5 pairs of ventral spines, metatarsus II with 4 pairs, metatarsus III with 2v and 1 pv, metatarsus IV with 1-1 <i>v</i> and 1 rl. Dorsal abdominal scutum as in fig. 767, ventral scutum (fig. 768) with short, non-grooved collar. Palp as in figs 769-770, embolus looping back on dorsal side of tegulum over 3/4 its length. FEMALE.
