Udvardya fortis sp. nov.

Figs 37–45 , 48–49 , 52

Type material: Female holotype from Oriomo, G.S., Papua W. District, New Guinea ( Papua New Guinea), 27.X.60, J.L. Gressitt, BISHOP 184.

Etymology. The name is a Latin adjective meaning strong and robust, due to its general appearance.

Diagnosis. Similar to U. elegans by the round, separated spermathecae and abdominal color pattern with oblique narrow lines, but can be recognized by the sclerotized, semicircular rim of copulatory opening. The insertion of the copulatory ducts at the spermathecae is also more posterior ( Figs 15, 17 , 43, 45 , 46, 48 ).

Description. Female (holotype, Figs 37–45 , 48–49 ). Spider about 6 mm long. Carapace dark brown, with longitudinal middle stripe and lateral patches of whitish hairs, located beside PLE and near the posterior margin ( Figs 37, 39, 40 ). Mouth parts and sternum brown. Abdomen grayish with light pattern of transverse and longitudinal stripes and patches, as in Figs 37, 39 , 49, 49 . Venter whitish, bordered by grayish areas ( Fig. 38 ). Spinnerets gray with light tips. Legs I brown, with paler tarsi; II–IV yellow, with brown femora ( Figs 37–40 ). Patellae I with prolateral patch of whitish hairs. Leg I spination: tibia 7+7, metatarsus 3+3 ventral spines. Epigyne: CO, CD, S, AG, FD as in Figs 43‒45 . Dimensions. CL 2.48, CW 2.00, CH 1.50, AEW 1.65, PEW 1.75, EFL 1.30, AL 3.60, AW 1.65, LI: 7.35 (0.80 + 0.60 + 1.50 + 1.05 + 1.70 + 1.20 + 0.50), LII: 4.75 (0.60 + 0.40 + 1.10 + 0.70 + 0.80 + 0.75 + 0.40), LIII: 4.55 (0.50 + 0.40 + 1.15 + 0.65 + 0.70 + 0.75 + 0.40), LIV: 6.10 (0.60 + 0.50 + 1.50 + 0.75 + 1.05 + 1.20 + 0.50).
