Tergite 1 metallic blue-green but yellow laterally; tergites 2–4 mostly yellow, but brown anteriorly along basal third and distal sixth, and with faint brown dorsal stripe dorsally; tergites 5–8 mostly dark brown with metallic reflections; hypopygium ( Figs 11, 12) mostly dark brown including cercus, but surstylus yellow; epandrium subrectangular; hypandrium with short hypandrial hood and long left lateral arm; surstylus elongate and curved with only fine setae; cercus basally with setose digitiform lateral projection, and divided into broad C-shape with dorsal arm curved and bearing lateral hairs and apical seta, and with ventral arm curved and blade-like and directed medially to meet ventral arm of other cercus along midline.

Female. Unknown.

Holotype: ♂ Papua New Guinea: Morobe Province, Mt Kaindi, nr Wau , 7.24°S 146.44°E, 1550– 2300 m, 14–29.x.1992, ex Caldchuria, Y. Basset ( BPBM). GoogleMaps

Remarks: Amblypsilopus kaindi is known only from the Mt Kaindi rainforest locality between 1150–2300 m near Wau, Morobe Province, Papua New Guinea. Males have an elongate tibia I and basitarsus I ( Fig. 10), and leg I tarsomere 4 has an ivory colored surface, while tarsomere 5 is modified into a black pinnate flag. The cercus is broadly C-shaped with setose dorsal arm and curved blade-like ventral arm directed medially to meet ventral arm of adjacent cercus along midline. This species has a rather long abdomen, about twice the combined length of the head and thorax together.
