Abstract
A cytological study of samples of Exochomus "lituratus" and E. "uropygialis" received from Indian and Pakistan has revealed the existence of previously unsuspectec species. Altogether they differ in chromosome number (2n = 16 and 18 due to chromosome fusion), morphology (acrocentric vs. metacentric autosomes), and type of Y sex-determining chromosome (again acrocentric vs. metacentric). In 2 entities supernumerary chromosomes are present.This publication has 6 references indexed in Scilit:
