The oldest predaceous water bugs (Insecta, Heteroptera, Belostomatidae), with implications for paleolimnology of the Triassic Cow Branch Formation
—A new genus and species of predaceous water bugs, Triassonepa solensis n. gen. n. sp., is described from the Triassic Cow Branch Formation of Virginia and North Carolina (USA) based on ~36 adult specimens and 51 nymphs. This species is the oldest known member of the extant family Belostomatidae. It is placed in a new genus based on the unique structure of the raptorial foreleg, in which the ta...
متن کاملThe significance of cytogenetics for the study of karyotype evolution and taxonomy of water bugs (Heteroptera, Belostomatidae) native to Argentina
Male meiosis behaviour and heterochromatin characterization of three big water bug species were studied. Belostoma dentatum (Mayr, 1863), Belostoma elongatum Montandon, 1908 and Belostoma gestroi Montandon, 1903 possess 2n = 26 + X1X2Y (male). In these species, male meiosis is similar to that previously observed in Belostoma Latreille, 1807. In general, autosomal bivalents show a single chiasma...
متن کاملPheromone Blends of Predaceous Bugs (Heteroptera: Pentatomidae: Podisus spp.)
Male predaceous stink bugs (Pentatom idae: A sopinae) in the genus Podisus release longrange a ttrac tan t pherom ones from a pair o f hypertrophied glands opening underneath the wings. Pherom one com positions are reported for four additional Podisus spp.: two N eotropi cal species (P. connexivus and an undeterm ined Podisus sp.), and two N earctic species (P. placidus and P. mucronatus). M a...
متن کاملSex chromosome differentiation in Belostoma (Insecta: Heteroptera: Belostomatidae).
Belostoma, a genus of the family Belostomatidae, includes species of great ecological importance as biocontrol agents. Few species of these species have been the subject of cytogenetic analyses. Karyotypic evolution in this genus involves agmatoploidy and simploidy; there are also different sex chromosome systems. We examined two Belostoma species (B. dilatatum and B. candidulum) collected from...
متن کاملBarcoding Bugs: DNA-Based Identification of the True Bugs (Insecta: Hemiptera: Heteroptera)
BACKGROUND DNA barcoding, the analysis of sequence variation in the 5' region of the mitochondrial cytochrome c oxidase I (COI) gene, has been shown to provide an efficient method for the identification of species in a wide range of animal taxa. In order to assess the effectiveness of barcodes in the discrimination of Heteroptera, we examined 344 species belonging to 178 genera, drawn from spec...
