A new species of Aeneolamia (Hemiptera: Cercopidae: Tomaspidinae) from the Neotropical Region

Abstract

Aeneolamia was described by FENNAH (1949) who designated Monecphora semifascia Walker, 1851 as the type-species. Species belonging to Aeneolamia are one of the main pests of sugar cane. The genus includes eight species and 34 subspecies, which have a wide variation in the color pattern on the tegmina. According to FENNAH (1949) there is a considerable variation in color between specimens of Aeneolamia, whether they are from the same localities or are separated in space. It is important to highlight that this polymorphism refers only to the coloration of the tegmina. The characters from male genitalia are conservative within the genus and are reliable to identify the species. Species of the genus have a wide distribution, occurring in Brazil,

More than 80 years without new taxa: analysis of morphological variation among members of Mexican Aeneolamia Fennah (Hemiptera, Cercopidae) support a new species in the genus

“…According to this pattern, our results show that elements of male genitalia easily discriminate males among the Aeneolamia analyzed (Figs 2, 8); despite the tegmen polymorphism found among them (Fig. 1), diagnostic characters of the genital plates, parameres, and aedeagus were found to be the same as in other Aeneolamia species (Paladini and Cavichioli 2013).…”

“…In comparison with the tegmen features of color, those characters of male genitalia have been shown to be conserved and therefore reliable for species identification and delimitation (Paladini andCavichioli 2013, 2015; this study). In species with polymorphic tegminal color patterns, the specimens' series display consistent discrete morphological features in different elements of male genitalia (Paladini and Cavichioli 2013;Paladini et al 2018;Aquino-Borges et al 2020). According to this pattern, our results show that elements of male genitalia easily discriminate males among the Aeneolamia analyzed (Figs 2, 8); despite the tegmen polymorphism found among them (Fig.…”

“…In the compilation of Carvalho and Webb (2005), the six species considered by Fennah were reported together with two additional species, A. albofasciata (Lallemand, 1939) and A. sanguiniplaga (Lallemand, 1938), and more than 30 subspecies. Years later, a new species from Brazil, A. bucca Paladini & Cavichioli, 2013 was proposed within the genus (Paladini and Cavichioli 2013). However, it was later assigned by the same authors to the genus Gervasiella , based on a cladistic analysis of morphological characters .…”

“…albofasciata nueva especie", UCV, deposited in CEAM) for its morphological similarities to A. albofasciata (Armendáriz-Toledano et al 2022). Members of Aeneolamia display intra-and interspecific variation in tegmina color, both within and among localities, placing great importance on male genitalia characters as reliable species identifiers, because they are conservative within the species (Fennah 1949;Paladini and Cavichioli 2013). Thus, we tested the hypothesis that A. aff.…”
