Tres casos teratológicos en Ligeidos (Heteroptera: Lygaeoidea) chilenos

Abstract

ResumenSe describen tres casos teratológicos en ejemplares de Lygaeidae de Chile. El primer caso corresponde a una hemiteria pronotal en Syzygitis poecilus (Spinola, 1852); el segundo caso corresponde a una oligomeria simple en la antena derecha de un ejemplar de S. poecilus; finalmente el tercer caso corresponde a una atrofia con anartrogénesis en Lygaeus alboornatus Blanchard, 1852. Se comentan y discuten las posibles causas de estas malformaciones.

The first case belongs to a pronotal hemitery in Syzygitis poecilus (Spinola, 1852). The second case belongs to a simple oligomery in the right antenna of a S. poecilus specimen. The third case belongs to an antennal atrophy with anarthrogenesis in Lygaeus alboornatus Blanchard, 1852. The possible causes of these teratosis are commented and discussed.

Teratological cases of the antennae in the family Aradidae (Hemiptera: Heteroptera)

“…Recently, there have been many new reports on teratology cases in South American Heteroptera (e.g. 17,18 ) including reports of the first malformation in the family Idiostolidae 19 . In addition to Heteroptera, the antennal malformations in other Hemiptera have only been well studied in the dwarfish males of the aphid genus Stomaphis Walker, 1870 20 .…”
