Pyrnus insularis , new species Figures 399, 400

Hemicloea plumea (misidentification): Rainbow, 1920: 234.

Rebilus fulvus (misidentification): Gray, 1974: 51.

NOTE: No evidence was supplied by Gray (1974) for the generic synonymy implied by his use of the combination Rebilus fulvus .

TYPE: Female holotype taken in forest bracts at location 14H on Lord Howe Island, 31 ° 33 ̍ S, 159 ° 05 ̍ E, deposited in AMS (KS44016).

ETYMOLOGY: The specific name refers to the distribution.

DIAGNOSIS: The epigynum resembles that of Pyrnus fulvus but has pronounced lateral margins (fig. 399).

MALE: Unknown.

FEMALE: Total length 15. Carapace light reddish brown; abdominal dorsum pale gray with wide dark gray marks at cardiac area and at about two­thirds of length, sides dark gray, venter white; legs light reddish brown, leg I darkest, anterior femora with morphologically ventral surfaces darkened, Leg spination: femora: I d1­1­0; II–IV d2­1­0; tibiae: I v4­3­3; III v2­2­0; metatarsi: I, II v2­ 0­0. Posterior median spinnerets with about 12 cylindrical gland spigots in each row. Epigynum with long, narrow, longitudinally divided atrium bordered by squared, u­shaped posterior and lateral margins, posterior margin situated at about one­fourth of epigynal length (fig. 399); median ducts long, translucent, separated for most of their length by attenuated triangular sclerite, spermathecae anteriorly with sharp bend, thumb­shaped (fig. 400).

OTHER MATERIAL EXAMINED: Lord Howe Island : no specific locality, 31 ° 33 ̍ S, 159 ° 05 ̍ E, Dec. 1915 – Jan. 1916 (A. Lea, SAM N1981/245), 1♀, (A.

DIAGNOSIS: The only other species of Pyrnus for which males are known is P. magnet , from which these males can easily be distinguished by the longer retrolateral tibial apophysis (fig. 450) and the longer embolus (fig. 449). Females can be recognized by the triangular epigynal atrium including a horseshoe­shaped median septum (fig. 451).

MALE: Total length 10. Carapace light brown; abdominal dorsum dark gray with two paramedian, longitudinal light gray stripes, venter pale white; legs light brown. Leg spination: femora I–IV d1­0­0; tibiae: I, II v3­4­1p; III, IV v1p­0­0; metatarsi: I, II v2­2­0; III v2­0­0. Palpal tibia and retrola­ teral tibial apophysis long, narrow (fig. 450); embolus long, narrow, s­shaped, distal portion carried in groove of translucent portion of ventral prong of median apophysis (fig. 449).

FEMALE: Total length 10. Coloration as in male. Leg spination: femora I–IV d1­0­0; tibiae I,II v3­4­1p; metatarsi: I, II v2­2­0; III v2­0­0. Posterior median spinnerets with five cylindrical gland spigots in each row. Epigynal atrium triangular, with v­shaped posterior margin and horseshoe­shaped median septum (fig. 451); spermathecae separated by wide translucent sclerite (fig. 452).
