Unusual Teratology for a Tenebrionid: Antennal Schistomelia inProbaticus granulatus(Allard, 1876) (Coleoptera: Tenebrionidae)

A remarkable teratological case in Carabus violaceus L. (Coleoptera: Carabidae) from Poland

“…As suggested by Ferrer et al (3), in the case of increased rates teratological cases may have potential as bioindicator. For example, Akimoto (20) reported that the proportions of teratological cases and mortality of first instars of gall-forming aphids, derived from the first sexual reproduction after the Fukushima accident, were significantly higher in the Fukushima population than in control populations from noncontaminated areas.…”

“…Bifurcations have been described regularly, for example of antennal segments (e.g. 3,4,5,6), parts of the legs (e.g. 7,5,6) or the thoracic scutum (8).…”

A Remarkable Teratological Case forEucymatodera parvaSchenkling, 1908 (Cleridae: Tillinae) from Namibia

“…Teratology can be defined as the study of the causes producing abnormalities, malformations or defects of the physical development (Ujházy et al 2012). Teratological examples have been described in almost all animal groups, including insects (Ferrer et al 2014). The importance of reporting teratological events in insects has been discussed by Glasgow (1925), Cockayne (1937) and Savini & Furth (2004).…”

“…Balazuc (1948) was the first to describe and classify various teratological cases within Coleoptera and provided a standard nomenclature for these abnormalities. Since the publication of his teratological glossary, numerous forms of teratomorphs in beetles (Carabidae, Cerambycidae, Chrysomelidae, Meloidae, Staphylinidae, Scarabaeidae and Tenebrionidae) have been reported and discussed by various authors, including Balazuc (1948Balazuc ( , 1968, Haget (1949), Green (1952), Winkler (1958), Strand (1959), Delkeskamp (1969), Frank (1981), Gamarra & Outerelo (1986), Osuna (1992), Ortuño & Hernández (1993), Navarrete-Heredia et al (2002), Lays (2003), Savini & Furth (2004), Asiain & Marquez (2009), Clark & Belo Nieto (2010), and Ferrer et al (2014).…”

“…Antennal defects have been regularly recorded for the order Coleoptera, especially in the families Cerambycidae, Carabidae and Staphylinidae (Balazuc 1948;Osuna 1992;Ortuño & Hernández 1993;Asiain & Márquez 2009). According to Ferrer et al (2014), teratomorphs are more frequent in Carabidae, Cerambycidae and Staphylinidae; however, the authors argue that these groups are among the most studied families of Coleoptera, and this bias in reports may be affecting the ratio of published terotological cases.…”
