7. Purposes of the project
Corroborate if L. curvipes and L. valgus are synonyms
Assess the variation among populations of L. curvipes
Identify different presumably emerging new species
Support the need of a comprehensive revision of Lachnopus

20. Summary Further studies
Lachnopus curvipes is clearly different from L. valgus
There are at least four different species with more restricted areas of distribution
Further studies
Redescribe Lachnopus curvipes
Describe the different morphotypes as formal species
Incorporate molecular and biogeographical information
