Type material.

Holotype: male, specimen in RBINS, with data PAPUA NEW GUINEA: Madang Province, Oromongu, 5.73S, 142.53E. 700 m a.s.l. 26 January 2014. Maurice Leponce leg. #P5097. Mixed lowland forest Mixed evergreen forest of foothills and mountains, beating. Paratypes: 3 males, 3 females, with same data (from collecting events: males: #P5088, #P5103, #P5110, females: #P5082, #P5071, #P5106).

Etymology.

From the Greek "all giving" or "all gifted", referring primarily to the gifts given us by the Levis, most memorably the 1254 species that Herb described, and the wonderfully abundant Thanksgiving celebration dinners that Lorna put on for their students each year. It is also the name of the dog Lorna had when Herb and Lorna were married.

Diagnosis.

Distinct in having the thoracic hump higher than the ocular area in both sexes (Figs 84, 87, 89). Males can be recognized by the shape of the RTA, with dorsal branch shorter than in P. omhifosga and twisted, and a very short ventral flange (Fig. 80). Females can be recognized by the lack of anterior pocket, the relatively large spermathecae (Fig. 81), and the long lateral extension of the sclerotized ducts near the posterior margin (Fig. 82).

Description.

Male (holotype). Carapace length 1.52; abdomen length 1.41. Carapace (Figs 83-85): Thoracic slope with a large hump which is higher than the flat ocular area (Fig. 84). Ocular quadrangle with rugose integument (Fig. 85), approximately as long as wide, occupying half of the carapace (0.75 long). Clypeus extremely narrow (Fig. 83). Chelicera (Figs 83, 84): Excavated medially, with an ectal spur on the paturon. Palp (Figs 78-80): cymbium with 3-4 macroseta on the apical part, bulb round, embolus looped twice around it, with a twist on the prolateral side of the bulb (black arrow Fig. 78) and a slight bend at the end. Ventral flange of RTA small, a slight hump; dorsal lobe well developed, with an elongated “S” shape. Legs: Leg I robust, each segment is at least twice as wide as other legs. Other legs slender. Abdomen: pear shaped, with a slight constriction at the anterior fourth/third. Colour (Figs 85-87 in alcohol): Body dark brown with a transverse pale band in the middle of the carapace and abdomen. Coxa I, leg II, proximal half of coxa IV, patella III-IV, metatarsus III, and all tarsi pale yellow. Trochanter and femur I dark brown, patella and metatarsus I dark yellow with a dark ventral side. Leg III-IV black except the pale yellow segments mentioned earlier (Figs 85-87).

Female: (paratype, from collecting event #P5013). Carapace length 1.41; abdomen length 1.54. Carapace (Figs 88, 89): As in male. Chelicera: unmodified. Legs similar to male except for the less robust first leg. Epigyne (Figs 81, 82): Spermathecae large, touching each other. Sclerotized ducts of spermathecal complex oriented laterally at back margin before proceeding anterior to the fertilization duct. Colour (Figs 88, 89): As in male.
