D e s c r i p t i o n: Body length 16 mm. Antenna almost filiform, with 43 flagellomeres; 1 st flagellomere 2.1x longer than wide, c.8 th flagellomere square, widest flagellomeres c.0.7x as long as wide; preapical flagellomere 0.8x as long as wide. Temple rather long, slightly narrowed behind eye. OOD 1.5. Occiput with transverse rugae; frons coarsely rugose-punctate. Face densely punctate, rugose-punctate centrally, facial orbit smooth between punctures. Clypeus with scattered punctures, smooth between punctures. Gena wide, 1.2x as wide as eye, with scattered punctures in ventral 1/2. Malar space 1.1x as long as width of mandibular base and 0.9x as long as 1 st flagellomere. Genal carina complete, not interrupted ventrally. Hypostomal carina narrow.

Mesosoma covered with brownish hairs. Mesoscutum densely punctate, smooth and shining between punctures. Mesopleuron coarsely punctate, coarsely striate in ventral 1/2. Metapleuron coarsely rugose-punctate; coxal carina present. Scutellum almost flat, wider than long, with scattered punctures. Area superomedia hexagonal, 1.2x wider than long; costula weakly present. Area petiolaris completely bordered by strong irregular rugae laterally. All coxae with dense long brownish hairs; hind coxa densely punctate and with small dense scopa presenting as a slightly elevated area. Hind femur 3.4x longer than wide, with dense punctures. Hind tibia with c.5 denticular spurs externally. All tarsomeres distinctly widened, 3 rd mid tarsomere c.1.2x longer than wide.

Metasoma semi-amblypygous, hypopygium moderately elongate (about as long as the length between its apical margin and the metasomal apex). Postpetiolus strongly widened, median field with fine regular aciculation. 2 nd tergite 0.68x as long as wide. Gastrocoelus impressed, with several ridges; thyridium slightly oblique, c.0.75x as wide as the interval. 2 nd and 3 rd tergites with fine dense punctures, 2 nd tergite not rugose medially. Ovipositor sheath slightly extending behind metasomal apex.

Color: Black. Antenna reddish basally and darkened in apical 1/3, with yellowish rings on flagellomeres 7-13. Scutellum and wide spots on 6 th and 7 th tergites yellow. 2 nd and 3 rd tergites reddish, with yellowish tint in apical parts; 3 rd tergite with black basal band. Coxae and trochanters black; legs otherwise red; all tibiae yellowish externally; hind tarsus blackish in apical 1/2. Wings with slight yellowish tint, pterostigma yellow.

Males unknown.

T a x o n o m i c a l r e m a r k The species belongs to group E 1 sensu HILPERT

(1992) and is characterized by the color pattern of 2 nd and 3 rd tergites, strongly enlarged tarsomeres and the semi-amblypygous metasoma with moderately elongate hypopygium.
