“…The first author of this note had observed antennal bifurcations in Carabus hortensis L. and Carabus problematicus Herbst, leg bifurcation in Nebria brevicollis (Fabricius), and duplication of ungues in Pterostichus niger (Schaller) (unpublished data). Trifurcations have been also described, for example in the middle leg of Phyllophaga glaberrima (Blanchard) (9) or in the antenna of Eucymatodera parva Schenkling (10). Other multiplications of body parts concern, for example, supernumerary ocelli (11).…”

Background and purpose: Teratological cases in insects can be of different characteristic, quite often they are bifurcations, for example of antennal segments or parts of the legs. The aim of this paper is to report a remarkable case of leg duplication in Carabus violaceus L. Materials and methods: In the context of an interdisciplinary monitoring in the frame of a conservation project on the European bison (Bison bonasus (L.)) in Poland the carabid fauna (Carabidae) on areas grazed by this species was studied using pitfall traps in the Pszczyna forest, located in Silesia Province, to the south of the town Tychy. The traps were located inside a mixed fresh coniferous forest, with domination of Scots pine (Pinus sylvestris L.). Results: Among the carabids gathered a remarkable teratological female specimen of the species Carabus violaceus L. with repeated anatomical duplications on the right front leg was collected. Conclusions: The repeated incident of bifurcation suggest a genetic base of the teratology. An increased rate of teratological cases may have potential as bioindicator.

“…Teratology has long been documented and studied in the field of arachnology (Kaston 1982, Jimenez andLlinas 2002). It is the science that deals with the causes and patterns of deformities, abnormalities and defects in the physical development of animals (Balazuc 1948, Ujhazy et al 2012, Burke et al 2018. Reporting teratological cases is important because they may indicate the effect a particular environmental condition may play during development and may be of general interest (Burke et al 2018).…”

Teratology is the science that deals with the causes and patterns of deformities, abnormalities and defects in the physical development of animals. Teratological occurrences can be due to genetic or environmental conditions. Ocular teratologies are common in hypogean spiders. This communication reports on the occurrence of ocular teratologies of the South African endemic spider family, Stasimopidae.Various museum collections resulting in 181 spiders were examined for cases of ocular teratologies. Six females and one male were found to display some form of teratology. The species found to exhibit these were, Stasimopus patersonae, S. robertsi, S. insculptus peddiensis, S. griswoldi, and three unidentified specimens.The teratologies range from reduced eye size to numerous additional eyes. The exact cause of the teratologies is unknown. They could, however, be linked to embryonic trauma or developmental issues, juvenile injury, or unusual environmental conditions during embryonal development. The spiders all survived to adulthood as in hypogeal spiders, eye sight is not the most relied on sense. Understanding the causes of teratologies is important as it may enable researches to predict the effect of increasing chemical use and global climate change on the embryology of spiders.
