Four new species, Grouvellinus nigerquadratus sp. nov., G. cruxniger sp. nov., G. luciaensis sp. nov., and G. borneensis sp. nov., are described from Borneo and illustrated in detail. Two additional species of the genus which remain undescribed are briefly diagnosed. The material was collected during Taxon Expeditions\’ field course which involved citizen scientists, students and taxonomists. Specimens were collected at altitudes between 270 m and 750 m above sea level using fine-meshed hand-nets and blacklight traps. The morphological species delimitation based on morphology was supplemented and congruent with mtDNA sequences which are the first DNA barcodes for the genus from Borneo. They were obtained in the field using a newly developed rapid and accurate MinION-based workflow. The inter \– and intraspecific genetic distances and the problems regarding cryptic species delimitation are discussed.

Ten new species of the genus Ancyronyx Erichson, 1847 from Sulawesi are described along with additions to the original description of Ancyronyx raffaelacatharina J\äch, 2004. Ancyronyx vincentarnoldi sp. nov. belongs to the Ancyronyx variegatus (Germar, 1824) species-group; Ancyronyx breviparamerus sp. nov., Ancyronyx hafti sp. nov., Ancyronyx henningi sp. nov., Ancyronyx konjo sp. nov., Ancyronyx longiparamerus sp. nov., Ancyronyx skalei sp. nov., Ancyronyx schoedli sp. nov., Ancyronyx tobada sp. nov. and Ancyronyx toraja sp. nov. belong to the Ancyronyx patrolus Freitag \& J\äch, 2007 species-group. Diagnostic characters are illustrated by photographs of habitus, line drawings of genitalia and by scanning electron micrographs. An updated checklist of all Ancyronyx species including distribution data is provided. Cox1 mitochondrial DNA sequences were amplified for nine of the species listed above and used to construct a haplotype network by the application of statistical parsimony. The molecular data support our morphological species concept except for two taxa that showed little genetic distance, but were distinguishable by the male genitalia.
