Type material. Holotype: male, PAPUA NEW GUINEA: Southern Highlands Province: Tualapa, near Wanakipa , 5.283° S, 142.498° E, elev. 1100 m a.s.l., 13–22 July 2008, forest edge, coll. W. Maddison & Luc Fimo Tuki, WPM#08-010 ( UBC-SEM AR00127 ) GoogleMaps . Paratypes: 1 female, PAPUA NEW GUINEA: Southern Highlands Province: Tualapa, near Wanakipa , 5.283° S, 142.498° E, elev. 1100 m a.s.l., 11–22 July 2008, old clearing (former garden), coll. W. Maddison, WPM#08-009 ( UBC-SEM AR00128 ) GoogleMaps ; 1 male, same data as previous GoogleMaps .

Etymology. Named in honour of Merrick and Lorraine Darley, important supporters of Conservation International's efforts to document biodiversity.

Diagnosis. Similar in color pattern and markings to Omoedus brevis , but can be easily distinguished by the long and highly coiled embolus ( Figs 107–108) and the paler legs ( Figs 101–106). Median septum of the epigynum is relatively wide ( Fig. 110), distinct from that in other species.

Description. Male (holotype, UBC-SEM AR00127). Carapace length 1.6 (variation 1.6–1.8, n=2); abdomen length 1.7. Chelicera ( Fig. 109): dark; with two promarginal teeth and one retromarginal tooth. Palp ( Figs 107–108): pale yellow. Retrolateral sperm duct loop about three quarters of bulb width. Embolus long and coiled for more than five circles. Retrolateral tibial apophysis long and gradually narrowed towards the tip. Tibia of first leg with six proventral and three retroventral macrosetae; metatarsus with five proventral and three retroventral macrosetae. Measurements of legs: I 5.8, II 3.6, III 4.1, IV 3.9. Color in alcohol ( Fig. 105): carapace dark brown to red brown, with iridescent scales in front of and behind PLEs; abdomen brown, anterior end light brown, covered with iridescent scales, posterior part with a pair of brownish markings; legs pale yellow without distinct markings.

Female (paratype, UBC-SEM AR00128). Carapace length 1.4; abdomen length 1.8. Chelicera: with two promarginal teeth and one retromarginal tooth. Tibia of first leg with four proventral and three retroventral macrosetae; metatarsus with three pairs of ventral macrosetae. Measurements of legs: I 2.9, II 2.5, III 2.9, IV 3.0. Epigynum ( Figs 110–111): window large; anterior end of median septum relatively wide. Color in alcohol ( Fig. 106): similar to that of male.
