The present study provides some novelty about the ground beetle (Coleoptera, Carabidae) fauna of Bulgaria and the distribution of the species across the country. It is based on various field observations during the period 1950-2015, and contains data of 200 (out of 753) Bulgarian carabid species from 25 tribes (out of 37 in Bul-garia). Collected species represent 27 % of all known Bulgarian carabids. Of all species in the list, 47 (23.5 %) are recorded for the first time in different regions in Bulgaria. Harpalus fuscipalpis Sturm, 1818 and Lionychus fleischeri Reitter, 1908 are new records for the Bulgarian carabid fauna. New altitude ranges are given for 11 species, as eight species experience an upward shift, and new lower altitude limits were found for three species.
A population of Neurergus crocatus Cope, 1862 from Ba & scedil;aran village (& Scedil;& imath;rnak, T & uuml;rkiye), originally reported in 2009 and not studied further since, was re-evaluated during fieldwork conducted in May 2025, providing the first data on oviposition and detailed morphology from this locality. Morphometric analysis revealed pronounced sexual size dimorphism, with females (mean total length: 156.8 mm) being larger than males (140.7 mm). Sexual dichromatism and cloacal dimorphism were consistent with previous descriptions of the species. Oviposition was documented, with eggs deposited in adhesive gelatinous capsules beneath submerged substrates. Despite its Vulnerable status on the IUCN Red List, N. crocatus remains poorly studied.
The species Pterotopteryx akha sp. nov. is described from the Chiang Rai region (northern Thailand) and figured. With this species this family and genus is for the first time recorded from Thailand. The female holotype is figured and a photo of a living specimen on the screen is also attached. The new species differs from P. nigrifasciata (Byun & Park, 2007) in the wing markings as well as in the structures of the genitalia. The biotope at the light trap is a natural rainforest on the hillside beside the village Akha Hill.
Currently, pollinators and particularly bees are highly threatened by habitat loss and fragmentation or even the introduction of invasive species as well as intensive use of pesticides, among others. In Colombia, nine species of bumblebees have been reported. Yet, information about their genetic diversity and structure in Colombia remains scarce. Based on a comparative phylogeographic approach, we aim to assess the genetic variation and potential presence of biogeographical patterns for five montane species across the three Colombian mountain ranges, and discuss the possible drivers of such patterns in light of the evolutionary and biogeography history of each species. Partial sequences of the mitochondrial genes cytochrome c oxidase subunit I (coxI), and the 16S rRNA and of the nuclear gene phosphoenolpyruvate carboxykinase (PEPCK) were amplified from specimens of Bombus rubicundus, B. robustus, B. pauloensis, B. funebris and B. hortulanus. Our maximum parsimony haplotype network analyses showed that only B. pauloensis has a clear genetic structure for all molecular markers. For B. funebris, B. robustus, and B. rubi cundus the structure was incipient, mostly driven by the coxI fragment. In B. hortu lanus, no spatial pattern was detected. We hypothesize that mountain ranges, which act as barriers, along with climatic variations, most probably influenced the patterns observed for B. pauloensis 16S and PEPCK, as has been reported for many other Andean taxa. In contrast, the weak or absent genetic structure observed in B. hortu lanus, B. robustus, B. rubicundus and B. funebris indicates the presence of gene flow, probably aided by the existence of passages within and across the mountain ranges which maintained p & aacute;ramo connectivity during glacial periods. Our results contribute to the estimation of the actual biodiversity and the distribution of the genetic variability of bumblebees in Colombia, much needed for the generation of policies oriented to the protection of pollinators.
One new species of Dampfiellidae (Oribatida)-Dampfiella phyllosetosa sp. nov. - is described, based on adults collected from forest litter in central Vietnam. The new species is characterized by the medium-sized body, a long, lanceolate-fusiform bothridial seta, narrowly lanceolate notogastral setae lm, lp, h1, h2, p1-p3, one pair of long notogastral cristae, striate-foveolate subcapitular mentum, and three pairs of genital and adanal setae. The following taxonomic combinations are suggested: Beckiella ambigua (Perez-Inigo, 1976) comb. nov., Beckiella dubia (Hammer, 1971) comb. nov., and Dampfiella opposita (Mahunka, 1982) comb. nov. The initial generic placement of Beckiella paratina Mahunka, 1983 is supported. An identification key to the known species of Dampfiella is provided.
