Tara? cf anomala (Keyserling, 1882) Ergane? cf cognata L Koch, 1881 Scorpion Mimic

Body length males 3.2mm interesting for a number of features: small size, habitus and behaviour very scorpion like, extreme flatness, bulging femurs leg I, extremely strong-looking "crone-finger" fangs, with bumps and scoops, rather like Ergane cognata, or Tara anomala two slender and pointy apophysis protruberances, one dark, one light, stout pairs of ventral spines tibia and metatarsus, white egg-like shapes in base of palp which is otherwise fairly simple and not greatly unlike Tara anomala, short dark curved embolus. As for teeth, apparently fissident. Val Davies and Marek Zabka remarked that there were some undescribed females and males of a small, flat spider, usually shaken from foliage (as these on this page were) with a similar male palp to that of Tara anomala but without such elongate coxa and trochanter (as is also the case here).

Female from above

This very small Salticid is very flat in the nature of the flat jumping spiders, Holoplatys species. The abdomen is deflated in death, but the spider was found this way, or very close to it, so this older female may have died of natural causes. Body length nearly 2mm. It was collected in Jevons Street Park, Enoggera catchment.
