Description 367-369
Cytogenetically, out of 262 species, only three species of
family Platystictidae has been reported worldwide. Present study
has been undertaken to study chromosome complement and its
characterization of more species of this family. Cytogenetic
analyses of Protosticta sanguinostigma Fraser, 1992 and Protosticta
uncata Fraser, 1931 of family Platystictidae, collected from
Andretta, Himachal Pradesh, India have been carried out on the
basis of conventional staining, C-banding and silver nitrate staining.
Both the species possess n=13m as haploid chromosome number
and X0-XX sex determining mechanism. One large bivalent is
present in all the meiotic stages of P. sanguinostigma which is
considered as the species specific character. Chromosome
complement of both the species shows variation in distribution of
C-bands and Nucleolar organizer regions (NORs). Cytologically,
both the species have been described for the first time.
