NOTA CIENTÍFICA
A teratological case in Eurydema eckerleini Josifov,
1961 (Hemiptera, Heteroptera, Pentatomidae)
Un caso teratológico en Eurydema eckerleini Josifov, 1961
(Hemiptera, Heteroptera, Pentatomidae)
Teratology is defined as the study of structural abnormalities (ASIAIN &
MÁRQUEZ, 2009). CARVAJAL et al. (2019) stated that antennal anomalies
are among the most common in heteropterans.
Eurydema eckerleini Josifov, 1961 had been considered to be endemic
to the Greek island of Crete and the Peloponnese (with an isolated report in
Turkey), but was found on the Greek Cyclades islands of Syros and Tinos,
too (SIMOGLOU & DIOLI, 2017). Recent photographic records confirm
that the species has colonized other Greek islands as well (INATURALIST,
2019).
Although there is a great number of specimens with structural and mor-
phological anomalies in heteropterological collections (ŠTEPÁNEK, 1927),
specific cases concerning this suborder of the Hemiptera are not published very
often. Thus, a teratological case in E. eckerleini is reported in this note:
On 07.08.2015, the author was able to take a photo of a specimen
of E. eckerleini in Pitsidia, a small village on Crete. The specimen
shows teratological malformations – specifically of the pronotum and a
hemelytron (Fig. 1). Nearly 50 % of the pronotum are deformed or even
missing. The affected hemelytron shows a loss of colouration, while its
texture does not seem to be affected. It seems that parts of the head are
also deformed. However, based on the photo, more details cannot be
described precisely.
This seems to be the first reported record of a teratological case in E.
eckerleini. In principle, anomalies of the pronotum and/or the hemelytra
seem to occur less often than antennal anomalies.

New teratological examples in Neotropical Staphylinidae (Insecta: Coleoptera), with a compilation of previous teratological records
Article
Full-text available
Teratology is the study of malformations that affect various organisms and may cause taxonomic confusion. The goal of this work is to compile the previously published information about malformations in species of Staphylinidae, to describe 10 teratological cases that have not been previously recorded in neotropical species of this family, and to point out the high frequency of these malformations in the studied specimens. The previously recorded cases were obtained from review of 13 papers, and the studied specimens were obtained on loan from several collections. In total, 43 teratological cases were compiled for Staphylinidae, belonging to 39 species from 8 subfamilies. Ten teratological cases are described for specimens from Belomtchus, Agrodes and Plochionocems. One of them occurs in B. apiciventris, 2 in A. elegans, 3 in P. hameralis, 3 in P.fulgens and 1 in P. splendens. Most of the anomalies affect the antennae (7 cases), but teratologies that affect mandibles (1 case), midlegs (1 case) and pronotum (1 case) are also presented.
