Summary: | There is an ambiguity about the taxonomic status of
Morimus
asper funereus
(Mulsant, 1862),
a saproxylic longhorn beetle, widespread in Bulgaria and other Balkan countries. It is a protected species under the Habitats Directive (Annex II) and under the Bulgarian Biodiversity Act. A recent molecular study, based on the cytochrome C oxidase subunit I (COI) and the second internal transcribed spacer (ITS2) gene sequences, found that all European and Turkish populations of
Morimus
should be referred to
M. asper
(Sulzer, 1776) (Solano et al. 2013). The territory of Bulgaria and some other Balkan countries remain as an unstudied gap in that research. Here we present preliminary results on the genetic divergence and diversity of
Morimus
populations on the Balkans based on COI gene sequences using material from Bulgaria and Albania and the haplotypes’ sequences of Solano et al. (2013) obtained from GenBank. The material collected from Bulgaria аnd two localities in Albania was identified based on morphology characteristics as
M. asper funereus
(44 samples),
M. verecundus bulgaricus
Danilevski et all., 2016 (1 sample from the type locality),
Morimus orientalis
Reitter, 1894 (1 sample from Strandzha Mts.) and
Lamia textor
(Linnaeus, 1758) (1 sample) used as an outgroup. All obtained sequences were analyzed and haplotype diversity was estimated. The results show that Bulgarian populations of
Morimus
demonstrate relatively high haplotype diversity in correspondence to the diversity of the other European populations. Also, a phylogeographical hypothesis of the linkage between Bulgarian and other Balkan populations was developed. Four main lineages of divergence were identified. In addition, our results support the assumption that
M. verucundus
is a tentative subspecies of the morphologically and genetically variable
M. asper. |
