Triatoma bassolsae sp. n. from Mexico with a key to species of
"phyllosoma" complex{/B} - According to the descriptions of five
closely related species of the genus Triatoma Laporte, 1832: T.
phyllosoma (Burmeister, 1835), T. pallidipennis (Stal, 1872), T.
picturata Usinger, 1939, T. longipennis Usinger, 1939 and T. mazzottii
Usinger, 1941 and further published studies, these species could be
included in a "specific complex" named as the species formerly
described. All these species are typical from Mexico and another
species was found in the same country, in the State of Puebla: Triatoma
bassolsae sp. n. This species was morphologically compared with the
other five of the "phyllosoma" complex, including the external male
genitalia. The most important characters used to separate T. bassolsae
from T. phyllosoma (which is the most similar to the other species) are
the morphometric relationships on the head, with a longer anteocular
region and a significant longer second rostral segment, a long and
conspicuous pilosity in different areas of the body and specially on
the head, and the characters of the anterolateral, lateral and discal
tubercles of the pronotum, very long and sharp in the new species. The
male genitalia has several differences between T. bassolsae and T.
phyllosoma specially significant on the surface of the endosome process
and on the branches of the phallosome support, separated at the apex in
the new species. Types and paratypes are incorporated in the respective
institutions in Mexico DF and Rio de Janeiro
