Type material. Holotype: male, PAPUA NEW GUINEA: National Capital District: Port Moresby, 9.443° S, 147.179° E, elev. 75 m a.s.l., 3–4 July 2008, coll. W. Maddison WPM#08-002 ( UBC-SEM AR00120 ) GoogleMaps . Paratypes: 1 female, same data as holotype ( UBC-SEM AR00121 ) GoogleMaps ; 2 females and 1 male in three vials, same data as holotype GoogleMaps .

Etymology. In honor of Kristin Swift and John Swift, who have generously supported Conservation International's work in New Guinea.

Diagnosis. Distinguished from other species by the light colored longitudinal stripes on the body ( Figs 147–152), the narrow embolic spiral of the male palp ( Figs 153–154) and the shape of the epigynal window ( Fig. 157).

Description. Male (holotype, UBC-SEM AR00120). Carapace length 1.8 (variation 1.8–2.0, n=2); abdomen length 2.1. Chelicera ( Figs 155–156): red brown; with one bicuspid promarginal tooth and one retromarginal tooth; inner margin concaved; front surface with a longitudinal ridge and a small process. Palp ( Figs 153–154): brown. Retrolateral sperm duct loop almost as wide as bulb. Embolus long and coiled for more than two circles with narrow spirals. Retrolateral tibial apophysis very thin. Measurements of legs: I 4.0, II 3.5, III 3.8, IV 4.2. Color in alcohol ( Fig. 151): eye area dark, other region of carapace red brown, with a medial stripe behind PLEs and two lateral stripes composed of white scales; abdomen dark brown, margins sandy yellow, with a wide medial light yellow longitudinal stripe containing a brown marking in the middle; ventral abdomen pale yellow with gray brown longitudinal markings; first pair of legs reddish brown to gray brown, other legs cream to gray brown.

Female (paratype, UBC-SEM AR00121). Carapace length 2.0 (variation 1.8–2.0, n=3); abdomen length 3.0. Chelicera: also with one bicuspid promarginal tooth and one retromarginal tooth. Measurements of legs: I 3.7, II 3.3, III 3.8, IV 4.3. Epigynum ( Figs 157–158): window large; median septum almost triangular; opening to the copulatory duct at posterior end of window. Color in alcohol ( Fig. 152): similar to that of male except the brownish marking in the middle of light yellow stripe on dorsal abdomen not obvious and legs cream lacking obvious markings.
