These numbers do not conform to those reported by SUZUKI (1954) where the diploid number in male was interpreted as 44 (42+X-1X-2). The disharmony in chromosome number between the two results may be attributable to the possible miscounting in SUZUKI{\textquoteright}S observation. Unlike previous reports on chromosomes of Agelena and most of other genera of spiders, A. limbata was shown to have some pairs of meta- or submetacentrics in its karyotype.},

	abstract = {Most spiders exhibit a multiple sex chromosome system, X1X20, whose origin has not been satisfactorily explained. Examination of the sex chromosome systems in the spider genus Malthonica (Agelenidae) revealed considerable diversity in sex chromosome constitution within this group. Besides modes X1X20 (M. silvestris) and X1X2X30 (M. campestris), a neo-X1X2X3X4X5Y system in M. ferruginea was found. Ultrastructural analysis of spread pachytene spermatocytes revealed that the X1X20 and X1X2X30 systems include a pair of homomorphic sex chromosomes. Multiple X chromosomes and the pair exhibit an end-to-end pairing, being connected by attachment plaques. The X1X2X3X4X5Y system of M. ferruginea arose by rearrangement between the homomorphic sex chromosome pair and an autosome. Multiple X chromosomes and the sex chromosome pair do not differ from autosomes in a pattern of constitutive heterochromatin. Ultrastructural data on sex chromosome pairing in other spiders indicate that the homomorphic sex chromosome pair forms an integral part of the spider sex chromosome systems. It is suggested that this pair represents ancestral sex chromosomes of spiders, which generated multiple X chromosomes by non-disjunctions. Structural differentiation of newly formed X chromosomes has been facilitated by heterochromatinization of sex chromosome bivalents observed in prophase I of spider females.},

	abstract = {An ultrastructural study was performed on the sex chromosomes (.male. X1X2X3O) during the spermatogenesis of T. domestica (Arachnida, Agelenidae). This study was carried out using random and serially cut sections. During pachytene and diplotene the 3 X chromosomes are longitudinally paired. Each of these consists of a central core of condensed chromatin, surrounded by a field of dense chromatin projections through which the chromosomes are in contact with one another. These projections may be responsible for the recognition and pairing of the sex chromosomes and in some way participate in their non-disjunction during anaphase I. A study of the structure and behavior of the sex chromosomes during spermatogenesis is also presented. The available information on non-synaptonemal complex-mediated chromosome pairing and a systematization of sex chromosome structure in spiders are discussed.},
