Holotype male: Splash Pot (JF-10), Junee-Florentine karst, Tasmania , Australia , on moist wall of stream (twilight and dark zones) to c. 40 m depth , 42°43'S , 146°34'E , 28.VIII.1987 , S. Eberhard ( AMS KS97172 ). Paratypes : Allotype female, Cauldron Pot (JF-2), Junee-Florentine karst, Tasmania , Australia , in deep part (dark zone) of cave, 2.IV.1990 , S. Eberhard ( QVM 13 : 13292); 1 male , same data as holotype ( AMNH ) . Etymology . The specific epithet is a noun in apposition, taken from the type locality. Diagnosis . Males and females of Micropholcomma junee can be distinguished from all other described congeners by the presence of only four vestigial eye spots (Figs 16A–B). Description . Holotype male : Total length 0.90. Carapace 0.39 long, 0.32 wide. Abdomen 0.59 long, 0.43 wide. Leg I femur 0.34. Cephalothorax, abdominal sclerites dark tan-brown; legs, abdomen dark tan-yellow. Carapace raised anteriorly, fused to sternum via pleural sclerites; dorsal surface of pars cephalica slightly convex in lateral view. Eyes reduced to four vestigial eye spots on anterior margin of pars cephalica. Chelicerae without bulging anterior projections; promargin with single peg tooth. Legs relatively short (leg I femur-carapace ratio 0.87); macrosetae absent. Abdomen oval, protruding posteriorly, covered with hair-like setae, each seta projecting from small sclerotic spot; dorsal scute large, covering most of dorsal surface of abdomen; lateral sclerotic strips present. Pedipalpal patella with distally-directed, flanged lRPA; tegulum smooth, without processes, with curved ETR; embolus long (length> 5× width), looping once around margin of tegulum (Fig. 17). Allotype female : Total length 0.84. Carapace 0.36 long, 0.30 wide. Abdomen 0.56 long, 0.37 wide. Leg I femur 0.37. Cephalothorax, abdominal sclerites tan-yellow; legs, abdomen pale cream. Carapace raised anteriorly, fused to sternum via pleural sclerites; dorsal surface of pars cephalica slightly convex in lateral view. Eyes reduced to four vestigial eye spots on anterior margin of pars cephalica. Chelicerae without bulging anterior projections; promargin without peg teeth. Legs relatively short (leg I femur-carapace ratio 1.03); macrosetae absent. Abdomen oval, protruding posteriorly, covered with hair-like setae, each seta projecting from small sclerotic spot; dorsal scute and lateral sclerotic strips absent. Pedipalp small, four-segmented, with fused tibia-tarsus. Epigyne with distinctive external morphology (Fig. 16D); spermathecae globular; insemination ducts coiled around arched fertilisation ducts (Fig. 15D). Distribution . Known only from the caves Splash Pot and Cauldron Pot in the Junee-Florentine karst of south-central Tasmania (Fig. 213). Remarks . Micropholcomma junee lives in sympatry with another troglobitic micropholcommatid, Olgania eberhardi sp. n. (see below). Nothing is known of its biology.
