Pyrnus baehri , new species Figures 457, 458 ; Map 36

TYPE: Male holotype from Mary River , 115 km E Darwin, 12 ° 33 ̍ S, 131 ° 41 ̍ E, Northern Territory (Aug. 29–30, 1995; M. Baehr), deposited in QMB .

ETYMOLOGY: The specific name is a patronym of in honor of Dr. Martin Baehr, collector of the holotype and many other gnaphosoids.

DIAGNOSIS: This appears to be the sister species of P. magnet , resembling it closely in both palpal morphology and coloration, but differing in the simple, triangular shape of the retrolateral tibial apophysis (fig. 458). The affinities with P. magnet make it extremely unlikely that the holotype could rep­ resent the male of P. fulvus or any of the island species.

MALE: Total length 6. Carapace light brown, abdominal coloration as in P. fulvus , legs yellow. Leg spination: femur I d1­1­0; tibiae: I v3­2­2; II v2­2­2; metatarsi I–III v2­ 0­0. Retrolateral tibial apophysis relatively short, triangular, with slightly sinuous tip (fig. 458); embolus shorter than in P. planus , distal portion carried in groove of translucent portion of ventral prong of median apophysis (fig. 457).

FEMALE: Unknown.

OTHER MATERIAL EXAMINED: None.

DISTRIBUTION: Known only from the Northern Territory (map 36).

Pyrnus pins , new species Figures 459, 460

TYPE: Female holotype from the ˆle ı des Pins, New Caledonia (Feb. 25–27, 1977; J. Balogh), deposited in HNHM .

ETYMOLOGY: The specific name is a noun in apposition taken from the type locality.

DIAGNOSIS: The female epigynum resembles that of P. planus but the epigynal atrium is shorter (fig. 459) and the spermathecae are larger (fig. 460).

MALE: Unknown

FEMALE: Total length 15. Coloration as in P. insularis . Leg spination: femora I–IV d1­ 1­0; tibiae: I, II v4­4­3; III v2­2­1p; IV v1p­ 0­0; metatarsi: I v3­2­0; II, III v2­2­0. Posterior median spinnerets each with two offset rows of six large cylindrical gland spigots. Epigynum with large triangular atrium restricted to anterior half of epigynum, with median septum occupying almost entire width of atrium (fig. 459); spermathecae wide, oriented transversely (fig. 460).

OTHER MATERIAL EXAMINED: New Caledonia: ˆle ı des Pins: Feb. 25–27, 1977 (J. Balogh, HNHM), 1♀, Oct. 1, 1977 (J. Balogh, HNHM, AMNH), 3♀, May 21–25, 1987 (J. Balogh, HNHM), 3♀.

DISTRIBUTION: Known only from the ˆle ı des Pins, off the southeast coast of New Caledonia.

Pyrnus numeus , new species Figures 461, 462

TYPE: Female holotype from New Caledonia, ‘‘probably near Noumea’ ’ (1942; Ostendorf), deposited in AMNH .

ETYMOLOGY: The specific name is an arbitrary combination of letters.

DIAGNOSIS: Females can easily be recognized by the short, wide epigynal atrium (fig. 461).

MALE: Unknown.

FEMALE: Total length 11. Coloration as in P. insularis . Leg spination: femora: I d1­1­ 0; II–IV d2­1­0; tibiae: I, II v2­3­2; III v1p­ 0­0; IV v0­0­0; metatarsi: I, II v2­2­0. Posterior median spinnerets each with two offset rows of six large cylindrical gland spigots. Epigynum with short, wide atrium (fig. 461); spermathecae small (fig. 462).

OTHER MATERIAL EXAMINED: One female taken with the holotype (AMNH), and one female from New Caledonia (no further data, QMB S26867 ).

DISTRIBUTION: Known only from New Caledonia.

Pyrnus aoupinie , new species Figures 463, 464 TYPE : Female holotype taken at an elevation of 900 m on Mount Aoupinie´, New Ca­

ledonia (June 18, 1996; M. Moulds), deposited in AMS (KS55342).

ETYMOLOGY: The specific name is a noun in apposition taken from the type locality.

DIAGNOSIS: Females can easily be recognized by the m­shaped posterior margin of the epigynal atrium (fig. 463).

MALE: Unknown.

FEMALE: Total length 18. Carapace dark reddish brown; abdominal dorsum, sides, and venter dark gray; legs dark reddish brown, femora with prolateral and retrolateral lighter, longitudinal stripes. Leg spination: femora I–IV d1­0­1; tibiae: I, II v6­4­4; III v2­ 2­1p; IV v1p­0­0; metatarsi: I v3­2­2; II v2­ 2­2; III v1p­0­0. Posterior median spinnerets with about 10 cylindrical gland spigots in each row. Epigynal atrium short, confined to anterior one­third of epigynum, with mshaped posterior margin (fig. 463); median ducts long, wide (fig. 464).

OTHER MATERIAL EXAMINED: None.

DISTRIBUTION: Known only from New Caledonia.

Pyrnus obscurus (Berland) ,

new combination

Figures 465, 466

Rebilus obscurus Berland, 1924: 188 , fig. 45 (female holotype from Tchalabel, New Caledonia, in NMB, examined).

DIAGNOSIS: Females resemble those of P. aoupinie but have a distinctive anterior epigynal hood (fig. 465).

MALE: Unknown.

FEMALE: Total length 19. Carapace dark reddish brown anteriorly, lighter posteriorly; abdominal dorsum, sides, and venter dark gray, dorsum with wide darker areas along midline; anterior legs dark reddish brown, posterior legs lighter. Leg spination: femora I–IV d1­1­0; tibiae: I, II v3­4­2; III v2­2­0; IV 1p­0­0; metatarsi: I, II v2­2­0; III v2­1p­ 0. Epigynum with wide anterior hood, atrium with double m­shaped posterior margins (fig. 465); lateral epigynal ducts longer than median pair, almost totally obscuring posterior ducts in dorsal view (fig. 466).

MATERIAL EXAMINED: Only the holotype, collected by J. Roux and F. Sarasin on May 5, 1911.

DISTRIBUTION: Known only from New Caledonia.
