FIGURES 2 in Molecular phylogeny of the weevil genus Kyklioacalles Stüben, with descriptions of a new subgenus Glaberacalles and two new species (Curculionidae: Cryptorhynchinae)
FIGURES 2. Distribution of Kyklioacalles punctaticollis meteoricus (marked in blue) and Kyklioacalles punctaticollis punctaticollis (marked in red). ․ Material used for sequencing; ˔ Morphological determination according to the structure of the internal sac of aedeagus (endophallus)—224 specimens from 81 localities are considered (position on map generalised); ․_․_․ Hybridisation zone (blue-red).
FIGURE 1. Bayesian 50 in Molecular phylogeny of the weevil genus Kyklioacalles Stüben, with descriptions of a new subgenus Glaberacalles and two new species (Curculionidae: Cryptorhynchinae)
FIGURE 1. Bayesian 50% majority rule consensus built from mitochondrial CO1 and 16S data. Numbers next to nodes indicate posterior probabilities. The scale shows the expected nucleotide substitutions per site and the bars next to the tree denote subfamily assignment. Taxonomic changes are indicated (new subgeneric placement only through subgenus bars). Numbers behind taxon names correspond to the DNA voucher. In combination with Appendix 1, they can be used to identify individual specimens (only given where informative).—Photos on right side: The only reliable morphological determination aid is the structure of the internal sac of the aedeagus. Here some characteristical endophalli of the respectice group or subgenus (see Stüben 2003a: Fig. KYKIS). Left side: above K. bupleuri on Bupleurum spinosum (Tunisia) and below the same species (= almadensis syn.) on Euphorbia nicaeensis (Spain). As all other Kyklioacalles also this species is nocturnal and climbs its host plant when the humidity is high enough at night.
