TI  - Presence of the canonical TTAGG insect telomeric repeat in the Tenthredinidae 
      (Symphyta) suggests its ancestral nature in the order Hymenoptera.

AB  - Telomeric repeats in two members of the sawfly family Tenthredinidae 
      (Hymenoptera), namely, Tenthredo omissa (Forster, 1844) and Taxonus agrorum 
      (Fallen, 1808) (both have n = 10), were studied using fluorescence in situ 
      hybridization (FISH). Chromosomes of both species were demonstrated to contain 
      the canonical TTAGG insect telomeric repeat, which constitutes the first report 
      of the (TTAGG)(n) telomeric motif for the Tenthredinidae as well as for the clade 
      Eusymphyta and the suborder Symphyta in general. Taken together with the presence 
      of this repeat in many other Holometabola as well as in the hymenopteran families 
      Formicidae and Apidae from the suborder Apocrita, these results collectively 
      suggest the ancestral nature of the (TTAGG)(n) telomeric motif in the Hymenoptera 
      as well as its subsequent loss within the clade Unicalcarida and independent 
      reappearance in ants and bees. If this is true, the loss of the TTAGG repeat can 
      be considered as a synapomorphy of the corresponding clade.
