Holotype male: Kubla Khan (MC-1), Mole Creek karst, Tasmania , Australia , from sheet web with vertical stay lines in cracks of wall above pool, near lower entrance (dark zone), 41°33'12"S , 146°16'52"E , 24.X.1990 , S. Eberhard ( AMS KS29793 ). Paratypes : Allotype female, same data as holotype ( QVM 13 : 12765) . Etymology . The specific epithet is derived from the Greek ‘typhlos’, meaning ‘blind’ ( Brown 1956 ), and refers to the absence of eyes in this species. Diagnosis . Males and females of Epigastrina typhlops can be distinguished from all other described congeners by the complete absence of eyes ( Fig. 65C ). Description . Holotype male : Total length 1.18. Carapace 0.53 long, 0.39 wide. Abdomen 0.70 long, 0.47 wide. Leg I femur 0.48. Cephalothorax, legs very pale tan-yellow; abdomen pale cream. Carapace raised anteriorly, not fused to sternum except around petiole; dorsal surface of pars cephalica slightly convex in lateral view. Eyes absent. Chelicerae each with large, bulging anterior projection; promargin with three peg teeth. Legs relatively short (leg I femur-carapace ratio 0.91); distal, prolateral macroseta present on tibia I. Abdomen oval, covered with hair-like setae; dorsal scute large, indistinct, covering most of dorsal surface of abdomen; lateral sclerotic strips absent. Pedipalpal patella with retrolaterally-directed, hooked lRPA and ornate, ridged cuticular microstructure; tegulum large, bulging posteriorly, with excavate ETR and very large, divergent, fleshy medial conductor bearing rod-like prolateral process and massive, fleshy retrolateral process; embolus short (length <5× width), spur-like, distally hooked, situated between divergent processes of conductor ( Fig. 66 ). Allotype female : Total length 1.12. Carapace 0.49 long, 0.40 wide. Abdomen 0.76 long, 0.55 wide. Leg I femur 0.43. Cephalothorax, legs very pale tan-yellow; abdomen pale cream, with darker tan-yellow epigyne. Carapace raised anteriorly, not fused to sternum except around petiole; dorsal surface of pars cephalica slightly convex in lateral view. Eyes absent. Chelicerae without bulging anterior projections; promargin without peg teeth. Legs relatively short (leg I femur-carapace ratio 0.88); macrosetae absent. Abdomen oval, covered with hair-like setae; dorsal scute and lateral sclerotic strips absent. Pedipalp entire, five-segmented. Epigyne heavily sclerotised externally, with distinctive, wedge-shaped epigastric plate ( Fig. 65D ); spermathecae globular, connecting to parallel, filiform insemination and fertilisation ducts ( Fig. 63E ). Distribution . Known only from the cave Kubla Khan in the Mole Creek karst of north-central Tasmania (Fig. 213). Remarks. Epigastrina typhlops is a highly troglomorphic and completely blind species, otherwise very similar to E. fulva and E. loongana .
