Dinelytron has many problems for identifications of its species, such as types lost, lack
of illustration on the original descriptions as well as succinct descriptions. This difficult the
species identification as well as the establishment of the boundaries between Prisopodini
genera. To solve this, 72 Dinelytron, 28 Damasippus Stål, 1875, 64 Prisopus Fargeau &
Serville, 1828 and 5 de Melophasma Redtenbacher, 1906 specimens, types and non-types
specimens had their morphology studied to propose a phylogenetic hypothesis. Through an
exhaustive search for a maximum parsimony tree, carried out at TNT software, six trees were
founded and a strict consensus between them was made. The strict consensus tree contains
Dinelytron, Damasippus and Prisopus compounding a monophyletic clad as well as showing
that the genera are not congeneric. As taxonomic result five new species were described from
Brazil: Dinelytron betinho sp. n., from Minas Gerais, Viçosa; Dinelytron leukommatos sp. n.,
from Pernambuco, Recife; Dinelytron olive sp. n., from Espírito Santo, Sooretama; Dinelytron
ramusculus sp. n., from Rio de Janeiro, Rio de Janeiro and Dinelytron trimaculatus sp. n.,
from Rio de Janeiro, Itatiaia.The following nomenclatural acts were proposed: Dinelytron
grylloides Gray, 1835, neotype pres. desig.; Dinelytron unilineatus (Redtenbacher, 1906) n.
comb., lectotype and paralectotype pres. desig. and Prisopus villosipes (Redtenbacher, 1906)
n. comb.. A pictorial identification key for Prisopodini genera and Dinelytron species is
presented. Prisopodini resulted in a monophyletic clad, as well as the three genera included,
with the following topology (Prisopus + (Damasippus + Dinelytron)). |
