Diagnosis

This is the only Eusparassus species in Eurasia with AME strikingly larger than the other eyes (1.5 times larger than ALE) ( Figure 15A View Figure 15 ). E. oculatus can also be recognizable by ET short and pointed proximo-ventrad ( Figure 15E View Figure 15 ) (larger and stouter than in E. kronebergi stat. nov.); vRTA broad and not well developed ( Figure 15C,D View Figure 15 ) (in contrast, that of E. potanini enlarged and prominent); in contrast to other species female, EFB absent and AMLL not developed around MS laterally ( Figure 16A,B View Figure 16 ).

Colouration [in ethanol]. Pale cream, dorsal opisthosoma with a patch and a series of small chevron-like patterns and additional dots, ventral opisthosoma pale.

Known geographical distribution

Central Asia including Afghanistan, Uzbekistan, Tajikistan, Turkmenistan and China: Xinjiang Uyghur.

Remarks

The type material was collected during the “Scientific Expedition to Turkestan” conducted by Alexis Fedtschenko to central Asia, Samarkand. After its original description by Kroneberg (1875) from Uzbekistan, it was recorded again by Denis (1958) from Afghanistan. Here we present further new records from Tajikistan and Turkmenistan based on material deposited in SZMN.
