“…Furthermore, Nascimento et al [ 55 ] also observed similarities between spermathecae morphology from P. lignarius, P. megistus and P. tibiamaculatus comb. nov., and Mello et al [ 56 ] recorded a relationship between exocorial cells in eggs of P. tibiamaculatus comb. nov. with Panstrongylus .…”

Do not judge a book by its cover: would Triatoma tibiamaculata (Pinto, 1926) belong to Triatoma Laporte, 1832, or to Panstrongylus Berg, 1879, with misleading homoplasies?

Background Triatoma tibiamaculata is a species distributed in ten Brazilian states which has epidemiological importance as it has already been found infecting household areas. The taxonomy of this triatomine has been quite unstable: it was initially described as Eutriatoma tibiamaculata. Later, the species was transferred from the genus Eutriatoma to Triatoma. Although included in the genus Triatoma, the phylogenetic position of T. tibiamaculata in relation to other species of this genus has always been uncertain once this triatomine was grouped in all phylogenies with the genus Panstrongylus, rescuing T. tibiamaculata and P. megistus as sister species. Thus, we evaluated the generic status of T. tibiamaculata using phylogenetic and chromosomal analysis. Methods Chromosomal (karyotype) and phylogenetic (with mitochondrial and nuclear markers) analyses were performed to assess the relationship between T. tibiamaculata and Panstrongylus spp. Results The chromosomal and phylogenetic relationship of T. tibiamaculata and Panstrongylus spp. confirms the transfer of the species to Panstrongylus with the new combination: Panstrongylus tibiamaculatus. Conclusions Based on chromosomal and phylogenetic characteristics, we state that P. tibiamaculatus comb. nov. belongs to the genus Panstrongylus and that the morphological features shared with Triatoma spp. represent homoplasies.

“…The descriptions herein are the first available from Mexico on T. rubida and T. mexicana in terms of egg ornamentation, while T. dimidiata eggs have been described for a Veracruz population (Mello et al 2009). It is worth stressing that there is a strong morphological and chromatic variation between populations of this species, and egg morphology is a useful trait given its wide distribution.…”

We describe and compare the morphology and morphometry of the egg exochorion for five species and two morphotypes of Mexican triatomines with scanning electron microscopy. The results show differences in egg ornamentation for each species, including between morphotypes. Polygonal ornamentation was observed in each species, including pentagons, octagons and, in certain cases, a majority of hexagons. We observed small perforations in T. protracta protracta, small spheres on the T. lecticularia polygons, a crown with festoons in T. barberi, and less complex ornamentation in T. mexicana. Through morphometric analysis, significant differences in egg dimensions were determined for the studied species. Journal of Vector Ecology 38 (1): 90-96. 2013.
