Figures 38 –40, 43–44, 60

TYPE MATERIAL: Female holotype ( AM KS129856) and male allotype ( AM KS129856) from Queensland, Thornton Peak, North of Daintree, 16° 10′ S, 145° 22′ E, 610 m. M. Gray, November 1975, rainforest site 39 ( AM). Deposited at AM.

DIAGNOSIS: Females of H. weintrauborum , can be distinguished from H. lipscombae by the absence of the triangular anterior margin protrusion as observed in lateral view (fig. 39B). In males of H. weintrauborum the dorsal cymbial ridge, in lateral view, is less pronounced than that of H. lipscombae (figs. 40F, 43D), the basal conductor sclerite ectal margin is flat (figs. 40F, 43B), in contrast to the projected conductor ectal margin found in H. lipscombae , and basal cymbial apophysis tip blunt (fig. 43E), in contrast to the acute tip found in H. lipscombae .

DESCRIPTION: Female (TEAU017, TEAU050) total length 4.91. Cephalothorax length 1.87, width 1.38. Clypeus height 0.80 AME diameter. Femur I length 3.66. Cephalothorax dark yellow, sternum light brown. Ultrastructure not examined with SEM. Epigynum as in figures: 39B, D, F; 44B, D, G.

Male (TEAU016) as female except as noted. Total length 4.15. Cephalothorax length 1.76, width 1.50. Clypeus 0.91 AME diameter. Femur I length 3.65. Palp as in figures: 40B, D, F, H; 43A–F.

VARIATION: Females (N = 2) total length 4.00– 4.91, cephalothorax length 1.72–1.89, width 1.30–1.31. The size of the triangular epigynal protrusion and the separation between the longitudinal grooves varies (this is best observed in ventral view).

ETYMOLOGY: This species is named by the third author (G.H.) to honor Robert L. and Frances Weintraub, whose endowment to the Department of Biological Sciences at the George Washington University for the study of systematics has led to the discovery of myriad spiders.

DISTRIBUTION: This species can be found in northeastern Queensland, southwest of Cape Tribulation (fig. 60A).
