Fomichev, Alexander A., Omelko, Mikhail M. & Marusik, Yuri M., 2024, Pamirosa gen. nov., unexpected record of Artoriinae (Araneae, Lycosidae) from the rooftop of Pamir, Central Asia, Zoosystematics and Evolution 100 (3), pp. 1005-1015 : 1005-1015

Pamirosa gen. nov.

Type species.

Pamirosa kudratbekovi sp. nov.

Etymology.

The generic name is derived from the type locality of the type species, Pamir Mountains, and end with – osa, typical ending for Lycosidae genera. The gender is feminine.

Diagnosis.

The new genus differs from all known genera of Artoriinae by the helicoid tip of embolus in male (vs. straight or smoothly curved) and by screw-shaped membranous copulatory ducts in female. The presence of membranous copulatory ducts is a unique character for Pamirosa gen. nov. which is unknown in all other genera of Lycosidae .

Relationships.

The new genus belongs to Artoriinae to judge from the following features: 1) small subtegulum located at retrolateral half of the bulb, 2) very complex tegular apophysis, 3) transversal course of the sperm duct, 4) absence of palea, 5) presence of tegular outgrowth prolaterally from the tegular apophysis, 6) presence of basoembolic apophysis, 7) lacking cymbial claws (modified macrosetae), 8) posteriorly opened epigynal fovea lacking any septum.

Comments.

Artoriinae are known to occur in the Indo-Malayan, Australasian, Pacific and Neotropical regions ( Framenau 2007; Piacentini and Grismado 2009). The majority of taxa of Artoriinae are located in Australia and New Zealand ( Framenau 2007). Among these are the following genera: Anoteropsis L. Koch, 1878 ; Artoria Thorell, 1877 ; Artoriopsis Framenau, 2007 ; Diahogna Roewer, 1960 ; Kangarosa Framenau, 2010 ; Kochosa Framenau et al., 2023 ; Notocosa Vink, 2002 and Tetralycosa Roewer, 1960 ( WSC 2024). Navira and Lobizon are restricted to the south of the Neotropical Realm ( Piacentini and Grismado 2009). One genus of Artoriinae , Syroloma Simon, 1900 , is known to be endemic to the Hawaiian Islands ( WSC 2024). Species from the poorly known genus Lycosella Thorell, 1890 were described by Simon ( WSC 2024) and Thorell ( WSC 2024) from Hawaiian Islands and from Sumatra Island. There are no published images and redescriptions of Lycosella species. Two species of Artoria described from southern Africa ( Roewer 1960) are most likely misplaced. Several species from this genus are known from the Malay Archipelago, Malay Peninsula and southeast China ( Framenau 2005; Wang et al. 2019; 2021). Finally, the genus Sinartoria Wang, Framenau & Zhang, 2021 , comprising two species, was recently described from the Daming Mountain in the tropical part of China ( Wang et al. 2021). Thus, Pamirosa gen. nov. extends the known range of Artoriinae about 6 ° to the North and 28 ° to the West and is the first record of the subfamily in Central Asia (Fig. 51 ). More reports of Artoriinae in Tibet, the Himalaya and the Karakoram can be expected.
