A new species of Mouse Spider (Actinopodidae, Missulena) from the Goldfields region of Western Australia

Volker W. Framenau¹,

Danilo Harms²

Abstract: A new species of Mouse Spider (family Actinopodidae Simon, 1892), Missulena harewoodi, is described from near the City of Kalgoorlie-Boulder in the Goldfields region of Western Australia. It differs from all other Missulena species by the unusual light grey colouration of the abdomen in combination with small body size and shiny carapace. A phylogenetic analysis of a fragment (658 bp) of the COI barcoding gene places M. harewoodi sp. n. in a clade with four Missulena species from the Pilbara region of Western … Show more

Actinopus specimens from different localities in Uruguay that did not match any of the previously species present in the country were examined, and four new species are described: A. coboi sp. nov., from Colonia province; A. fernandezi sp. nov., from Salto province; A. simoi sp. nov., from Maldonado province; and A. uruguayense sp. nov., from Colonia and Cerro Largo provinces. The record of the species A. longipalpis for Montevideo is rejected and A. liodon is considered “species inquirenda”. Actinopus coboi has spermathecae with an apical lobe diagonally directed; A. fernandezi is characterized by a stylized copulatory bulb and its greater number of retrolateral thorns on tibia II. Actinopus simoi can be distinguished from A. uruguayense by its carapace with a dark coloration; a reddish coloration in the palpal tibia and the shape of its spermathecae and copulatory bulb. With the presence of the Argentinian species—A. gerschiapelliarum, A. puelche and A. insignis—the number of species known in the country is increased to nine. All new species are diagnosed and illustrated; a dichotomous key to all species of Actinopus from Uruguay is also provided.

Mouse spiders (genus Missulena Walckenaer, 1805) are a lineage of trapdoor spiders with males of many species having a brightly coloured red cephalic region, an abdomen that is tinged metallic blue, and the habit of wandering during the day in search of a mate. A total of 17 species of Missulena have been described in Australia to date but most descriptions are based exclusively on males and always small numbers of specimens. Here, we describe three new species of Missulena from the Pilbara and Goldfields regions of Western Australia based on morphology and genetic data: Missulena davidisp. nov. (male and female), M. iugumsp. nov. (male) and M. manningensissp. nov. (male). One of them is presently known only from its type locality and another one from a small range based on two specimens but M. davidi sp. nov. has a linear range of almost 300 km and is genetically highly structured. We use genetic data for 75 specimens as a foundation to evaluate morphological variability in this species and note substantial variation in several characters commonly used to identify species such as body size, colouration, rastellum shape and eye distances. This variation does not necessarily relate to phylogeographic structure as inferred from the genetic data, but rather seems to reflect natural variability both within and between localised populations. Overall, our results stress the need to evaluate a large series of specimens for mygalomorph taxonomy and provide an interesting example of intraspecific variability in hard-to-collect species that are usually underrepresented in museum collections.
