( Figs 10–19 View FIGURES 10 – 15 View FIGURES 16 – 19 )

Type material. Holotype male in UBC – SEM with labels: " PAPUA NEW GUINEA: Southern Highlands Province: Umgé. S 5.3054 E 142.5098 and S 5.3059 E 142.5111. 1400 m a.s.l. 16–17 July 2008. W. Maddison & Aislan Tama Wanakipa Indiaf. WPM#08–014", " Allococalodes madidus Maddison , Holotype " " UBC –– SEM AR 00020". Paratypes: 3 females, 1 male, 9 juveniles with same collecting data.

Etymology. The Latin madidus means wet or moist, referring to the habitat of mossy vines and trunks along a forest stream.

Diagnosis. Tibial apophyses of male palp much smaller than in A. alticeps Wanless and A. cornutus Wanless , not projecting retrolaterally as in those species.

Description. Male (holotype). Carapace length 2.5; abdomen length 2.2. Chelicerae elongate, projecting forward, in life held together ( Fig. 13 View FIGURES 10 – 15 ). Four promarginal and two retromarginal teeth. Intercheliceral sclerite elongated into a horn as in other Allococalodes and Cocalodes . Palpus ( Figs 16–17 View FIGURES 16 – 19 ) with embolus short and accompanied by a conductor and median apophysis, as in the other two species of Allococalodes ( Wanless 1982) . Median apophysis flat, leaf-like. Tibia of first leg with three pairs of ventral macrosetae; first metatarsus with three pairs. Carapace high, with posterior eyes on tubercles and area of fovea concave. PME large. Colour ( Figs 10, 11, 13 View FIGURES 10 – 15 ): carapace and abdomen dark brown except paler longitudinal stripe on thoracic slope and dorsally on abdomen. Recumbent golden-orange setae concentrated near eyes and over heart; white setae over thoracic stripe; black elsewhere. Palpi pale olive yellow except cymbium red-brown. Legs somewhat annulate olive and black.

Female (paratype, UBC – SEM AR 00020). Carapace length 2.9; abdomen length 3.4. Chelicerae: three promarginal and three retromarginal teeth. Palp with tarsal claw. Tibia of first leg with three pairs of ventral macrosetae; first metatarsus with 3 pairs. Epigynum ( Fig. 18 View FIGURES 16 – 19 ) with two small posterior openings. Carapace high, with posterior eyes on tubercles and area of fovea concave. PME large. Colour ( Figs 12, 14, 15 View FIGURES 10 – 15 ): as in male.

Natural history. All specimens were found on moss-covered surfaces within a few metres of a shaded stream in the forest at mid elevation. Most were on moss-covered trunks of small trees and vines ( Fig. 87 View FIGURES 87 – 92 ).
