Type material. Holotype female: Mostyn Hardy Cave (Old Tourist Cave) (L-4), Loongana karst, Tasmania, Australia, dark zone, 41°25'S, 146°00'E, 22.II.1969, A. & T. Goede ( AMS KS72935 ). GoogleMaps

Etymology. The specific epithet is a noun in apposition, taken from the type locality.

Diagnosis. Females of Epigastrina loongana can be distinguished from all other described congeners by the presence of only six reduced eyes ( Fig. 64B View Figure 64 ). Males are unknown.

Description. Holotype female: Total length 1.10. Carapace 0.49 long, 0.40 wide. Abdomen 0.69 long, 0.49 wide. Leg I femur 0.41. Cephalothorax, legs very pale tanyellow; 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. Six reduced eyes present on anterior margin of pars cephalica; AME absent; PME separated by twice their own diameter. Chelicerae without bulging anterior projections; promargin without peg teeth. Legs relatively short (leg I femur-carapace ratio 0.84); 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. 64C View Figure 64 ); spermathecae globular, connecting to parallel, filiform insemination and fertilisation ducts ( Fig. 63D View Figure 63 ).

Distribution. Known only from Mostyn Hardy Cave in the Loongana karst of north-central Tasmania (Fig. 213).

Remarks. Epigastrina loongana is a troglomorphic species with reduced eyes, otherwise very similar to E. fulva and E. typhlops .
