description: 4.2. Hetaerina calverti, a cryptic species
Genetic and morphological data of both females and males suggest that H. calverti is a new species that is reproductively isolated from H. americana. However, although the differences in morphological structures such as the cerci in males and the intersternites in females differentiate the species, it is important to mention that interspecific variation in other characters such as wing-spot and body coloration is practically absent and, as we have already mentioned, this has been one of the biggest problems in the identification of possible new species within “ H. americana ”.
In recent years, the discovery of cryptic species in different groups, including odonates, has been increasing (Damn et al. 2010). However, the causes of morphological stasis in these species remain unknown. Due to this, new questions arise such as: Are we underestimating the diversity of odonates? What is the importance of the reproductive system in cryptic speciation? And, bearing in mind that H. americana is one of the first species of damselflies described in North America (i.e. more than 200 years ago) and one of the best studied, it would not be surprising if this phenomenon is very common in other less studied odonates. It is also important to mention that in the work of Vega-Sánchez et al. (2019) the sampling was mainly in Mexico, hence it is possible that other cryptic species are found in northern and southern parts of the distribution, for example in California, Guatemala, El Salvador, Honduras and Nicaragua.
