Notes on spermatocyte chromosomes of Neope goschkevitschii (Menetries, 1857) and Neope niphonica niphonica Butler, 1881 (Lepidoptera, Nymphalidae, Satyrinae)

Abstract

The haploid chromosome number in males of Neope goschkevitschii from Iwata-shi and Nobeoka-shi is 46, with a single element which can be distinguished from the rest by its larger size. The chromosome constitutions in two examined males of Neope niphonica niphonica from Chichigatani of Miyagawa-mura (Mie-ken) differ from each other. The male, No.1, has an n, 28-karyotype. In the male, No.2, the haploid chromosomes total 29 in primary spermatocytes and both n, 29- and n, 28-secondary spermatocytes are observed in the second division. The n, 29-spermatocyte retains one B chromosome which is the smallest in the complement.
