New insight into the systematic position of the endemic Madagascan genus Amberiana (Hemiptera: Heteroptera: Dinidoridae) using 12S rDNA sequences

Abstract

The systematic position of the endemic Madagascan genus Amberiana Dist. is studied using DNA sequences (the mitochondrial 12S rDNA subunit) for the first time. The phylogenetic relationships within the superfamily Pentatomoidea were computed using neighbor-joining, maximum parsimony, minimum evolution, and maximum likelihood methods, as well as Bayesian estimation. All results based on the mtDNA analyses stand in contrast with previous morphological data. The mtDNA analysis showed close relationships of the genus Amberiana to the genus Sehirus (Cydnidae: Sehirinae) and to species of the family Parastrachiidae, whereas the morphology indicated that the genus was a typical representative of the family Dinidoridae. A new tribe, Amberianini trib. nov., is proposed for the genus Amberiana. Furthermore, a key to all tribes of the subfamily Dinidoridae is provided with their diagnostic characters and included genera.

A revision of Sagriva (Hemiptera: Heteroptera: Dinidoridae)

“…The dinidorid genus Sagriva Spinola, 1850 has remained monotypic since its original description, only including the South and Southeast Asian species S. vittata Spinola, 1850. In the currently accepted higher classifi cation of Dinidoridae, proposed by DURAI (1987) and modifi ed by KOCOREK & LIS (2000) and LIS et al (2012LIS et al ( , 2015, Sagriva was placed into the subfamily Dinidorinae, tribe Dinidorini. Pterygopolymorphism (the occurrence of specimens with differently developed wings within a given species) is unusual in all families of Pentatomoidea; Sagriva is apparently the only genus of Dinidoridae in which distinctly brachypterous individuals occur, though the holotype of a member of Cyclopelta Amyot & Serville, 1843, C. robusta Lis & Lis, 2001, has somewhat shortened fore wings with reduced membrane, cf.…”
