RESUMO
An assessment was performed regarding the accuracy of various types of data deposited in the Barcode of Life Data system (BOLD) related to the true bug family Cydnidae (Hemiptera: Heteroptera). Taxonomic nomenclature and classification, identification reliability, and the correctness of the data provided in the "Taxon description" were analyzed and commented on with respect to both available versions of the BOLD system, i.e. version 3 and beta version 4. Numerous mistakes in taxonomy, the relevance of the taxa names, and species misidentifications in BOLD version 3 were found and, more importantly, similar errors were detected in BOLD version 4 as well. We suggest that if the BOLD system is presumed to be taxonomically trustworthy, it can't exist without an adequate a priori identification of barcoded specimens. Otherwise, the erroneous data deposited onto the BOLD platform will have a negative impact on studies in which molecular data imported from BOLD are utilized.

Ochetostethomorpha secunda sp. nov. from Namibia, the second species of the South African endemic genus is described, illustrated, and compared with O. nollothensis Schumacher, 1913. The new species is the third of the subfamily Sehirinae known from Namibia. Moreover, a DNA barcode sequence was generated for this new species (827 bp of cytochrome oxidase I) and was deposited in GenBank.

The genus Aethus in Cambodia is known only from a single species collected in the 1950s that was originally identified as A. indicus. However, what was regarded as A. indicus in the Oriental and Australian regions appeared to consist of three sibling species, recognizable only on the basis of male genital structures, i.e., A. philippinensis, A. pseudindicus, and true A. indicus. To date, the lack of males representing this genus from Cambodia made it impossible to verify which species actually occur in this country. The present study, based on eight males collected at the same locality in Cambodia where the specimens were originally identified as A. indicus more than 50 years ago (i.e., Siem Reap), confirmed the occurrence of A. pseudindicus, not A. indicus, as previously reported. Male genitalia, i.e. the paramere, the opening of genital capsule, and the apex of aedeagus, are described and their photographs are provided for both species.
