Miturgopelma echidna sp. nov.

Figs 2d, 3d, e, 28–30

Diagnosis. Males differ from those of all other species by the large lateral lobe on the RTA and the shape of median apophysis (Figs 29a, 30a). Female unknown.

Etymology. The species epithet is a noun in apposition from the Australian monotreme with sharp spines on its back, like the spines dorsally on the male cymbium (Figs 29b, 30b).

Colour: carapace yellow brown with 2 dark brown sashes from and including PLE to caput edge for length of carapace; margins with dark borders widest on posterior corner. Opisthosoma dorsally dark brown with 2 large subcircular patches anteriorly and 2 predistally; centrally a dark zigzag band with 2 small pallid areas laterally then breaking into wide chevrons separated by thin white bands; venter pallid with uniform brown flecking of 30–40 small spots. Femora yellow brown lightly mottled and with dark hair. Carapace: Uniform dense cover of black hairs in sash and pale brown hairs in intervening zone.

Eyes: Eight in 2 recurved rows; front edge of ALE in base of back edge of AME, back row +-2 rows. PME>AME=PLE>ALE. Group front width: back width: length, 40:49:34. Eye sizes: AME, 11; ALE, 7; PME 9; PLE 10. Interspaces: AME–AME 5; AME–ALE 1, PME–PME 5, PME–PLE 8. Chelicerae: Promargin with 3 teeth, retromargin with 2. Sternum: centrally directed hairs from submargin weak and not dense.

Legs. Trochanteral notches ca. x 1.5 wider than deep. STC with 3 long wide teeth. Scopula: Thin in 2 lateral bands for 3/4 of metatarsi I–IV; denser but still thin on tarsi I–IV, all divided by band of 2–4 setae; pseudotufts small.

Spines: I: fe pv1p1d2r1; pa 0; ti p2v2.2.2 me p1r1v2.1. II: fe pv1p2d3r3; pa 0; ti p2v2.2.2; me p2.1v2.1. III: fe pv1p3d3r4; pa 0; ti p2d2.1r2v2.2.2; me p1.2.1r2.2.1v2.1.1.1.

Spinnerets: PLS and ALS long cylindrical; PLS ca. 0.5 x diameter of ALS and slightly longer with conical apical article; PMS smaller cylinders.

Palp: Tibia short. RTA bipartite; ventrally with deep thick V- shaped retrolateral process longer than tibia, outer lobe lightly sclerotised, glabrous thick with broad rounded upturned apex, inner lobe more sclerotised conical; dorsal of two lobes a crescentic process, inner edge rounded, outer sharply pointed sclerotised the two parts joined by trough, a narrow sclerotised fold on distal edge unsclerotised deep on ectal edge. Cymbium with light ovoid scopulate area in distal third; light hairs mixed with many thick spine-like bristles longest basally. Apical cone short pointed with 10–15 short thick bristles apically. Lateral margins all narrow. Median apophysis a short claw-like hook with low longitudinal ridge off prolateral edge and fold retrolaterally joining with long base fitting notch in tegulum; fused prolaterally to embolus. Embolus with narrow central origin widening quickly and recurving back to median apophysis where small conical conductor cradles its tip. Tegulum gourd-shaped for full length retrolaterally. Subtegulum large G-shaped with basal lobe.

Distribution. Known from Victoria, South Australia, Queensland, and New South Wales.
