Thorelliola Strand, 1942


Genus Thorelliola Strand, 1942

Small to medium sized spiders. Carapace is usually high. Males of some species have setae enlarged into “horns” on the clypeus and some of them have a truncus for the “horns” on the clypeus ( Gardziṅska & Patoleta 1997; Szű ts & De

Bakker 2004). Chelicera has a fissident retromarginal tooth. Many species have a process distally on the front surface of the male chelicera. Epigynum has a big window without median septum. Some species have a pair of secondary spermathecae in addition to the primary spermathecae. Male palp of many species has prominent macrosetae on the tibia and also on the femur in some species; tegulum lacks proximal lobe; embolus is long or short.

In total, 12 species have been reported from Southeast Asia, Papua New Guinea and the Pacific Islands ( Platnick 2012). Some of the new species described here are not congruent with the described species in the appearance and in that males only have ordinary setae rather than robust “horns” on the clypeus. However, unpublished molecular data indicate that they fall into a clade with the typical Thorelliola species including the type species Thorelliola ensifera (Thorell) . Thorelliola mahunkai Szű ts has “horns” not robust but more like ordinary setae (Szű ts 2002). Thus, using the “horns” on the male clypeus to define the genus Thorelliola may be too restricting. Here we expand the delimitation of the genus Thorelliola (see above) to comprise more species and to avoid erecting more new genera for jumping spiders.
