Type Material. Holotype male: QUEENSLAND: Mt Glorious Road, -27.3355873, 152.7702610, Mt Glorious, 5th of February 2023, E. Yeoman. Paratype female: QUEENSLAND: Mt Glorious Road, -27.3357743, 152.7701547, Mt Glorious, 28th of October 2022, E. Yeoman.
Diagnosis. Males are most like A. personata Ledoux, 2004 (Fig. 4A; Ledoux, 2004) in the structure of the RTA, which is triangular and splayed distally. Easily distinguished from such by the PA, which is more basally situated and proximally directed, and by the RTA, which is projected more distally from the palpal tibia and cymbium. Females are most like A. andersoni sp. nov. in the general structure of the epigyne, distinguished by the insemination ducts which join to the spermathecae laterally (opposed to more anteriorly in A. andersoni) and lack a distinct bend in the posterior portion.
Description. Holotype male. Measurements.TL: 1.44. AL 0.81, AW 0.61; CL 0.67, CW 0.57; SL 0.42, SW 0.41; LL 0.10, LW 0.12; ML 0.18, MW 0.18; AMS 0.12 (0.12), ALS 0.17 (0.17), PLS 0.21 (0.20). Eye sizes and interdistances: AME 0.03, PME 0.04, ALE 0.04, PLE 0.04; AME-AME 0.03, AME-ALE 0.01, ALE-PLE 0.01, PME-PME 0.05, PME-PLE 0.03; AERW: 0.20; PERW: 0.24. Cephalothorax chocolate brown, row of long setae projecting from foveal region to eye group. Eyes all with dark borders; in dorsal aspect, PER appears slightly procurved, AER appears straight. Abdomen dorsally dark brownish with pale chevrons beginning at anterior edge and descending to spinnerets; ventrally brownish with paler central marking, spinnerets whitish, basal segment of ALS brown. Sternum broadly shield-shaped, concolorous with labium and maxillae; anterior edge of maxillae with keel comprised of small denticles, inner anterior edge with serrula. Chelicerae concolorous with cephalothorax, retromargin and promargin each with 2 triangular teeth. Pedipalp: Cymbium unmodified. Tegulum simple, circular. Embolus, short, emerges prolaterally and terminates retrolaterally, apex supported by ovoid median apophysis. Spermduct circumvents tegulum, emerges promedially. RTA conspicuous in ventral aspect, fin-like, splayed retrolaterally at ca. 30° angle; in retrolateral aspect, triangular, tapers to rounded apex. Palpal tibia with large basally situated retro-ventral to -lateral, bulge. PA proximally directed, somewhat triangular in shape, with small subapical notch or tooth in ventral aspect.
Paratype female. Measurements. TL 2.00. AL 1.19, AW 0.90; CL 0.71, CW 0.62; SL 0.42, SW 0.42; LL 0.10, LW 0.12; ML 0.18, MW 0.18; AMS 0.11 (0.16), ALS 0.20 (0.22), PLS 0.32 (0.28). Eye sizes and interdistances: AME 0.03, PME 0.06, ALE 0.05, PLE 0.05; AME-AME 0.03, AME-ALE 0.01, ALE-PLE 0.01, PME-PME 0.06, PME-PLE 0.03. AERW: 0.23; PERW: 0.27. Cephalothorax, abdomen, sternum, labium, and maxillae as in male. Chelicerae, retromargin with 2 teeth, promargin with 1 tooth. Epigyne: very small and simple, insemination ducts short, join to small spheroid spermathecae, fertilisation ducts short, curved; small accessory structure (reduced secondary spermathecae receptacle?) located on insemination ducts, situated just before ID joins with spermathecae.
