«Taxonomic Revision, Molecular Phylogeny and Zoogeography of the huntsman spider genus Eusparassus (Araneae: Sparassidae) Dissertation for attaining ...»

-- [ Page 8 ] --

Remarks. The type specimens were collected during ―the 3rd Danish Expedition to Central Asia‖ in Afghanistan conducted by K. Paludan (South and East) and N. Haarløv (North, West and Centre) from May to August 1948. The specimens, two females and one juvenile, were deposited in ZMUC and described later by Denis in 1958. Knut Lindberg (1892–1962) from Lund, Sweden, conducted an expedition to Afghanistan between 1957 and 1960. Later on, Roewer (1962) found one female and one male in the collection of Knut Lindberg (MZLU) and described the male for the first time. Unfortunately, this material could not be traced.

Fortunately, an important and rich collection of spiders from Jalal-Abad, Afghanistan exists in MMB which was included in the present study; several females and one male of E.

fuscimanus are properly described here.

Known geographical distribution and habitat preferences. Eusparassus fuscimanus is recorded from a dry wooded valley in Wama, Nuristan (1500 m) to higher elevation in the Baba Mountain range, central Afghanistan (3500 m). Spiders were found under stones.

Epigyne/vulva. As in diagnosis with EF longer than wide, AMLL well developed anteriorly but not encircling MS entirely, EFB distinctly separated from AMLL (Figure 17F); glandular pores located on a globular process of vulva (Figure 17G).

Colouration [in ethanol]. cream to dark yellow, ventral opisthosoma pale.

Remarks. The description and illustration of E. nanjiangensis (sub Heteropoda nanjiangensis) by Hu and Fu (1985), as well as examination of the type series, match the male holotype of E. potanini. Additional females (along with sympatric males) examined from around the type locality, revealed conspecifity of them with the holotype female of E.

nanjiangensis. Herewith, this species is proposed as a junior synonym of E. potanini.

Known geographical distribution. Autonomous region in Xinjiang Uyghur, China, the most northeastern distribution range of Eusparassus species.

kronebergi stat. nov. has two small and separated glandular parts; It can also be distinguished
