AB  - Telomeric repeats are general and significant structures of eukaryotic 
      chromosomes. However, nothing is known about the molecular structure of telomeres 
      in the enigmatic hemipteran suborder Coleorrhyncha (moss bugs) commonly 
      considered as the sister group to the suborder Heteroptera (true bugs). The true 
      bugs are known to differ from the rest of the Hemiptera in that they display an 
      inverted sequence of sex chromosome divisions in male meiosis, the so-called sex 
      chromosome post-reduction. To date, there has been no information about meiosis 
      in Coleorrhyncha. Here we report a cytogenetic observation of Peloridium 
      pomponorum, a representative of the single extant coleorrhynchan family 
      Peloridiidae, using the standard chromosome staining and fluorescence in situ 
      hybridization (FISH) with a (TTAGG) n telomeric probe. We show that Peloridium 
      pomponorum displays 2n = 31 (30A + X) in males, the classical insect (TTAGG) n 
      telomere organization and sex chromosome post-reduction during spermatocyte 
      meiosis. The plesiomorphic insect-type (TTAGG) n telomeric sequence is suggested 
      to be preserved in Coleorrhyncha and in a basal heteropteran infraorder 
      Nepomorpha, but absent (lost) in the advanced heteropteran lineages Cimicomorpha 
      and Pentatomomorpha. The telomere structure in other true bug infraorders is 
      currently unknown. We consider here the inverted sequence of sex chromosome 
      divisions as a synapomorphy of the group Coleorrhyncha + Heteroptera.
