Type material

Lectotype: male, AFGHANISTAN: Seistan , Faizabad, 14 February 1949, K. Paludan leg. ( ZMUC 5671 ) ; Paralectotype: 1 female, Afghanistan : Farah Province: Farah, (station 87), 18 June 1948, K. Paludan leg. ( ZMUC 5675 ) .

Other material examined

Diagnosis

Males of E. kronebergi can be distinguished from other congeners by vRTA (compared to that of E. walckenaeri ) not well developed ( Figure 11C,D ) and embolus tip directed retrolateralo-distad, in ventral view ( Figure 11E ); in contrast to E. walckenaeri , epigyne with MS as wide as long, and to E. doriae stat. nov., EF longer than wide ( Figure 11F ); vulva with a distinct crest laterally ( Figure 11G ).

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

Remarks

Morphological evidence allows this species to be withdrawn from the synonymy ( Levy 1989) with E. walckenaeri . Syntypes were collected in Afghanistan during “the 3rd Danish Expedition to Central Asia”. These are one male and one female collected allopatrically. There is the possibility that they are not conspecific. Consequently, to designate a unique bearer of the name of the nominal species (Article 74), we select the male to be the lectotype of E. kronebergi stat. nov. to fix the status of the species. Two other males sampled from Rajastan were found to be conspecific. This is the first record of the species from India

Known geographical distribution

Western Afghanistan; India: Rajastan (new record).
