A cytotaxonomical investigation on spiders (arachnida: Araneae)

Abstract

Cytological studies on three species of spiders from Turkey (Araneae:Lycosidae, Theraphosidae) were studied. Adult and sub adult forms were used as a material. In the study, it has been determined that in Lycosidae family, diploid chromosome number is 12, in ovaries taken from sub adult female Arctosa perita (Latreille, 1799) and diploid chromosome number is 18, in testis taken from sub adult male Lycosa narborensis (Walkenaer, 1806). On the other hand; this value was determined as 2n = 16 from Theraphosidae family in sub adult female Chaetopelma anatolicum (Schmidt, Smith, 1995). But, the total length of chromosomes is less than 2 μm. So the measurements of morphometric characters were not made. © 2005 Taylor and Francis Group, LLC.
