Tribe Acalyptaini (<i>Hemiptera: Tingidae</i>: Tinginae) Revisited: Can Apomorphies in Secondary and Tertiary Structures of <i>18S rRNA</i> Length-Variable Regions (LVRs) Support Tribe Validity?

Description
Summary:The lace bug tribe Acalyptaini (Tingidae: Tinginae) includes five genera, <i>Acalypta</i>, <i>Derephysia</i>, <i>Dictyonota</i>, <i>Kalama,</i> and <i>Recaredus,</i> and it was recently resurrected based on morphological and karyological characters. We aimed to validate the distinctiveness of this tribe using <i>18S rDNA</i> sequences, which have not been used in previous Tingidae phylogenomic studies. Our results confirmed the monophyly of the tribe. Moreover, the monophyly of the subfamily Cantacaderinae and its basal position within the family Tingidae were indicated, as well as the position of the tribe Litadeini as sister to all other Tinginae. In addition, we attempted to determine the apomorphic morpho-molecular characters in the secondary and tertiary structures of length-variable regions of the <i>18S rRNA</i> sequences of the analysed species. The results showed that two LVRs (LVR X and LVR L) of the hypervariable region V4 exhibited significant variability in the number of nucleotides and could be considered for apomorphic recognition.
