ABSTRACT
Lelo, S. Variation of saccus shape in the population of Leptidea sinapis Linnaeus, 1758 (Lepidoptera, Pieridae, Dismorphiinae) from wider area of Sarajevo. The saccus size and shape represents an important taxonomic character in males of genus Leptidea. In spite of that, the more commonly used character for the identification of species is morphometry of the saccus, while the analysis of saccus is scarcely done. This paper deals with detailed analysis of the shape of the saccus in the local population of Leptidea sinapis (Linnaeus, 1758) species form the Sarajevo wider area. Through analysis, there were four different phenotypes identified, with detailed records and subsequent statistical analysis of the complete sample and subsample which were defined by above see level height of regions where these butterflies were captured.
Key words: Leptidea, sinapis, reali, saccus, variability, variation.

SUMMARY
In the study of relationships between insect’s taxa, great attention is being payed to a qualitative, as well as quantitative characters of its genital apparatus, because it is often taken as a disciriminative systematic character. So, in order to determine male of genus Leptidea Billberg, 1820, quite often are being used morphometric characters: aedeagus and saccus length. These are very important attributes for a differentiation of species L. reali Reissinger and L. sinapis Linnaeus on the european soil, and, on the other hand, of species L. lactea Lorković and L. sinapis Linnaeus i L. morse Fenton in Asia.
However, there was none scientific paper, recovered among an accessible literature data, that would contain precise analysis of variability level for chosen character, as well as level of its changes over generation, in distinct population. Therefore, it has been decided to take a detailed investigation of such character’s variability in the extent of one population, in order to get precise insight into the variability level. of this character. This was done for the most abundant species of named genus in Bosnia and Herzegovina and in its whole areal.
Detailed analysis of saccus length on 288 males of species L. sinapis Linnaeus caught in Sarajevo surroundings has shown that mentioned attribute varies in ranges: 0,53-0,67-0,83 mm (I – 0,58-0,70-0,83, II – 0,53-0,65-0,76, III – 0,56-0,64-0,69). Range of variation can be perceived on behalf of three conditionally characterized phenotypes: (1) short saccus (0,529-0,625 mm), (2) middle long saccus (0,626-0,721 mm) and (3) long saccus (0,721-1,825 mm). It has been noticed that, according to the given categorization, middle long saccus is in all generations the most abundant variante of phenotype, while first and second phenotype have shown relative increase of abundancy, third phenotypes variante has shown relative decline of abundancy in later generations. Analogous, it has been detected that average values are smaller in second generation, having very constant variability coefficient – on the population level 8,19 (in generations: I – 7,49; II – 7,28; III – 6,56). In the end, by means of statistical analysis it has been determined that it doesn’t exist statistically significant difference between compared categories, noticed values have slightly wider range of variation than in earlier published data.
