clade. The analysis showed that one of the three studied specimens genetically differed from the other two. The genetic distance between these specimens was 1.7% for 18S sequence fragments and 6.2% for both 16S and CO1 fragments. Two other specimens did not differ genetically and had no substitutions in any of the studied sequences. These results may be indicative of an unrecognized complex of cryptic sympatric species.
