Abstract

We report on the results of a chromosomal study of the big-eyed true bug Geocoris dispar Waga, 1839 (Heteroptera: Geocoridae) aimed at obtaining data on its telomeres. Using fluorescence in situ hybridization (FISH), we have shown, that G. dispar has a non-canonical 10-bp telomeric motif TTAGGGGTGG. This is the first evidence of telomere structure in the family Geocoridae and the first finding of the telomeric sequence (TTAGGGGTGG)n in the large superfamily Lygaeoidea (infraorder Pentatomomorpha).
