Prodorsum with prominent median crista; lateral carinae reach sinus; posterior furrows distinct; median sigillar field long, narrow, slightly broadened anteriorly longer than laterals; sensilli long filiform, rough, without head; interlamellar and lamellar setae long, robust, covered with small spines in distal end, similar in shape to notogastral setae; rostral setae short, spiniform, rough, directed inward, exobothridial setae of medium length; ss> in> le> ex> ro. Notogaster with two median cristae along the dorsal part; setae of medium length (c 1> c 1 -d 1), robust setae covered with small spines in distal end, only setae c 3 are whole ciliated, setae c 1 located far from anterior border, setae c 2 remote, setae c 3 near the border. Ventral region; arrangement of genital setae: 4: 5; anoadanal plate with 5 pairs of rough setae, four of setae arranged at paraxial border of plate and small setae ad 3 remote from border, setae ad 2 thickest and longest. Chaetome of legs complete; setae d on femora I curved and slightly remote from distal end of article.
