PAPUA NEW GUINEA: Enga Province: Kai-ingri , 5.579° S, 143.053° E, elev. 3240 m a.s.l., 7–9 July 2008, coll. W. Maddison & Manisé Kulé, WPM#08-005 .

Etymology. Named for George Meyer, an important supporter of Conservation International's efforts in Papua New Guinea.

Diagnosis. Similar in body form to Omoedus omundseni , but differs in the presence of dark patches on the dorsum of abdomen ( Figs 112–119); the narrower bulb and embolic spiral of the male palp ( Figs 120–121); and the narrower window of the epigynum ( Fig. 123). This species can be distinguished from O. papuanus by the presence of guanine deposits in the eye area ( Figs 118–119); the markings on the abdomen ( Figs 118–119); the thinner and more coiled embolus ( Figs 120–121; four circles in O. meyeri ; three circles in O. papuanus ); and the wider median septum of the epigynum ( Fig. 123).

Description. Male (holotype, UBC-SEM AR00125). Carapace length 1.8 (variation 1.8–2.2, n=7); abdomen length 2.3. Chelicera ( Fig. 122): dark; with one bicuspid promarginal tooth and one retromarginal tooth. Palp ( Figs 120–121): tibia and cymbium dark brown, other segments pale yellow. Retrolateral sperm duct loop about two thirds of tegulum width. Embolus long, coiled for more than four circles. Retrolateral tibial apophysis relatively thin. Measurements of legs: I 4.8, II 3.9, III 4.1, IV 4.1. Color in alcohol ( Fig. 118): eye area with guanine deposit, carapace dark brown, with a medial light yellow brown stripe behind fovea, lateral margins light yellow brown; abdomen brown, with brownish markings and a pair of large dark patches near the center; legs light brown with dark borwn annuli. Some specimens darker in color ( Figs 115–116).

Female (paratype, UBC-SEM AR00126). Carapace length 1.7; abdomen length 2.5. Chelicera: with one tooth on promargin and retromargin each. Measurements of legs: I 3.5, II 3.2, III 3.8, IV 4.1. Epigynum ( Figs 123–124): window large, with opening to copulatory duct close to its posterior end. Color in alcohol ( Fig. 119): similar to that of male except carapace and abdomen a bit darker in color.

Natural history. Specimens were found beating trees at forest edge and grassland bushes, at high elevation.
