Diagnosis. Differs from E. minor as follows: male palp with a large ventral conductor process, a basally angled and apically elongated embolus, and a large RDTA; epigynal fossa indistinctly divided by a weak median ridge and lateral fossa margins extended inwards as thin “flanges”.

Description

Male (holotype). BL 6.65, CL 3.22 (range 3.10–3.39), CW 2.33, CapW 1.22, EGW 0.88, LL 0.43, LW 0.43, SL 1.59, SW 1.35. Legs: 1423 (I: 15.58; II: 13.17; III: 11.58; IV: 14.25); ratio tibia I length:CW = 1:0.66. Male palp ( Fig. 16a,b View Fig ). Bulb with a reduced, indistinct TL, with a tightly looped sperm duct visible retrolaterally. Embolus a long, curved spine, thick and strongly angled basally just before entering the conductor groove, then tapering and slender distally. Prolateral limb of conductor wide with a triangular flange; retrolateral limb extended as a long, translucent, curved spine supporting the elongate embolus and making a loose loop around the ventral conductor process.VCP very large with a thickened base. TW basal. MA surrounded by a collar-like membraneous area. RDTA a robust, ventrally concave, tapering process.

Female (KS57656). BL 8.37, CL 4.00 (range 3.22–4.00), CW 2.53, CapW 1.88, EGW 1.16, LL 0.61, LW 0.59, SL 1.80, SW 1.51. Legs: 1423 (I: 14.33; II: 12.25; III: 10.58; IV: 13.00); ratio tibia I length:CW = 1:0.69. Epigynum ( Fig. 16c–e View Fig ). Fossa longer than wide, weakly divided by a median ridge; anterolateral fossa margins extended as thin, flangelike laminae (“fl” in Fig. 16c View Fig ) over the anterolateral fossa floor and copulatory openings (these flanges may be broken off— Fig. 16d View Fig ); posterior fossa floor with a pair of adjacent “socket-like” recesses. Copulatory duct openings anterolateral, widely separated. Internal genitalia. Copulatory ducts very short, of moderate width; spermathecae small.

Distribution. Known only from Eungella NP area, mideastern Queensland.

Etymology. The species name refers to the large size of the male palpal ventral conductor process.
