description: Genus <i>Pua</i> Forster, 1959 <i>Pua</i> Forster, 1959: 299. Type species by original designation <i>Pua novaezealandiae</i> Forster, 1959. Brignoli, 1983: 374. Platnick, 2009. <b>Affinities.</b> The genus <i>Pua</i> appears to be the sister-lineage to <i>Micropholcomma</i> from Australia (Fig. 4). <b>Diagnosis.</b> <i>Pua novaezealandiae</i> can be distinguished from all other Micropholcommatini by the presence of a short (length &lt;5× width), hooked embolus situated distally on a rotated bulb (Figs 29 A–C). Other diagnostic characters include the loss of the AME (Fig. 25B), the presence of very large, globular spermathecae (Fig. 15F), and the presence of a dorsal scute on the female abdomen (Fig. 24B). <b>Description.</b> Very small, entelegyne Araneoidea; total length 0.80 to 1.00. <i>Cephalothorax</i>: Carapace without glandular depressions above maxillae (Fig. 26D); cuticle without glandular pits (Fig. 26E); margins fused to sternum via pleural sclerites. Six eyes present on anterior margin of pars cephalica (Fig. 25B); AME absent. Chelicerae without bulging anterior projections in males; promargin with true teeth, a pair of fused setal sockets adjacent to base of fang and single peg tooth in males (Fig. 27F). <i>Legs and female pedipalp</i>: Legs three-clawed (Fig. 28D), covered with smooth or serrate hair-like setae. Trichobothria present on legs; tibiae each with two (legs I–III) or three (leg IV) trichobothria (Fig. 28C); metatarsi without trichobothria. Female pedipalp four-segmented, with fused tibia-tarsus; claw absent (Figs 27 C–D). <i>Abdomen</i>: Abdomen oval-globose; anterior sclerite present around epigastric region and petiole; large dorsal scute present on males and females (Figs 24 A–B); lateral sclerotic strips present on males; posterior sclerotic ring surrounding spinnerets and colulus. Six spinnerets situated posterior to fleshy colulus (Figs 23 C–D); PMS without AC gland spigots; PLS with complete triad. Anterior tracheal system well-developed, with relatively large lateral atria and multiple radiating tracheae; second tracheal tubes on each side looping mesally and extending through petiole into cephalothorax; posterior tracheal spiracle absent. <i>Genitalia</i>: Male pedipalp (Fig. 29) relatively simple; patella with distally-directed, hooked ligulate retrolateral apophysis; bulb rotated 180 degrees, with embolus inserting distally relative to cymbium; tegulum smooth, with straight, evaginated tegular ridge; embolus exposed, short (length &lt;5× width) and hooked; conductor absent. Female genitalia (Fig. 15F) with pair of separate, very large, globular anterior spermathecae; insemination ducts short, barely visible in dorsal view; fertilisation ducts simple, curved. <b>Distribution.</b> New Zealand. <b>Composition.</b> Only the type species <i>Pua novaezealandiae</i> Forster, 1959.
