Parahelpis Gardzinska & Zabka, 2010
Parahelpis has two Australian species: P. abnormis and P. smithae. The genus is part of an Australasian clade (Maddison et al 2008) including the Australian genera Adoxotoma, Arasia, Astia, Astilodes, Helpis, Jacksonoides, Megaloastia, Sondra and Tauala. Genera from Indonesia (Katya) and the Philippines (Orthrus) may also be part of this group (Maddison 2015). Further information on the genus and described species can be found in Richardson and Żabka (2017).
Known only from male specimens, Parahelpis spp. are medium to large-sized, slender spiders, body length 10 to 15 mm, with an elongate-ovate abdomen. The head, viewed from above, is pear-shaped, widest well behind the posterior lateral eyes. The cephalothorax is high, with a gentle thoracic slope starting immediately behind the posterior lateral eyes. Chelicera are long and have five or more (plurident) retromarginal teeth and four or more promarginal teeth. The first legs are very long and slender with four pairs of ventrolateral spines. The third legs are the shortest.
The male’s palpal tibia has a short or long, broad, bifurcate retro-lateral tibial apophysis. The tegulum is long, with a large proximal lobe. The seminal duct runs up the centre of the tegulum. The embolus is short.
The structure of the epigyne is unknown.
Specimens of this genus have been found in rainforest and woodland under rocks.
Parahelpis has been collected in New South Wales and Queensland.
