Wolfniana Cavichioli: Description of a new species and redescription of Wolfniana limbatula (Auchenorrhyncha: Cicadellidae)

ABSTRACT

Wolfniana ancora sp. nov. is described based on specimens collected from the states of Mato Grosso, Acre, and Rondônia, Brazil. Wolfniana viridis is newly recorded from the state of Acre, and Wolfniana limbatula (Osborn, 1926) is redescribed, with its external morphology illustrated for the first time. A revised generic diagnosis, an identification key to males, and an updated distribution map are provided. Distribution patterns are discussed within the context of Amazonian Conservation Units, highlighting their importance for the preservation of these taxa.

INTRODUCTION

The tribe Cicadellini has a cosmopolitan distribution but is highly diverse within the Neotropical region, comprising approximately 1,200 species and 170 genera (Dmitriev 2022, Pecly et al. 2024). Members of this tribe are efficient xylem-feeders with the potential to transmit plant pathogens to economically important crops, making them a group of significant agricultural interest (Pinedo-Escatel and Blanco-Rodríguez 2024).

WolfnianaCavichioli, 2000 was established to accommodate Cicadella limbatula Osborn, 1926, which had previously been placed in Rotigonalia by Young (1977). The erection of the genus was justified by distinct morphological differences between C. limbatula and other species of Rotigonalia, particularly in the shape of the head and the paraphyses (Cavichioli 2000). Notably, C. limbatula lacks the conspicuously inflated clypeus that characterizes Rotigonalia (Cavichioli and Takiya 2012). Although Wolfniana limbatula has been illustrated (Young 1977, Cavichioli 2000) and described (Cavichioli 2000), no photographs of its external morphology have been published to date. Subsequently, Wolfniana viridis Cavichioli & Takiya, 2012 was described based on specimens collected from the state of Amazonas, Brazil. Currently, the genus is known only from the Amazon Basin, with confirmed records from Ecuador, French Guiana, and the Brazilian states of Amazonas, Rondônia, and Mato Grosso do Sul (Cavichioli and Takiya 2012). Previous records from Costa Rica (Young 1977) and southern Brazil (Young 1977, Cavichioli 2000) have since been proven erroneous: the Costa Rican specimen belongs to a different taxon, possibly even a different genus, and the southern Brazilian record resulted from a misinterpretation of the locality, which in fact corresponds to Rondônia rather than Rio Grande do Sul (Cavichioli and Takiya 2012).

Wolfniana is considered part of the Juliaca Melichar, 1926 genus group sensu Young (1977) and can be distinguished from related genera by its predominantly dark green coloration, paraphyses with a pitted, sculptured apex, and a short aedeagal shaft (Cavichioli and Takiya 2012). In this study, we describe a new species of Wolfniana based on specimens from the states of Acre, Mato Grosso, and Rondônia, Brazil, and redescribe W. limbatula, providing the first photographs of its external morphology. We also present a revised diagnosis for the genus, an identification key to males, and an updated distribution map.

MATERIAL AND METHODS

The morphological terminology adopted herein primarily followed Young (1977), except for the facial areas of the head, which followed Mejdalani (1993, 1998). For the female genitalia, terms followed Nielson (1965), with the inclusion of “gonoplac” and “sculpted areas of first ovipositor valvulae” as proposed by Mejdalani (1998). Techniques for genitalia preparation followed Domahovski (2024). Dissected parts were stored in microvials containing glycerin and pinned beneath their respective adult specimens, following Young and Beirne (1958).

Digital habitus images were captured using a Leica MZ12.5 stereomicroscope equipped with an SCMOS 05000KPB digital camera. Image layers were stacked using CombineZ5 software and processed with Adobe Photoshop CS6. The first and second valvulae, along with the gonoplacs, were dissected, mounted on temporary slides with coverslips, and photographed at 40× and 100× magnifications using the same digital camera attached to a Nikon optical microscope.

Examined specimens are deposited in the Coleção Entomológica Pe. Jesus Santiago Moure, Departamento de Zoologia, Universidade Federal do Paraná, Curitiba, Brazil (DZUP). The distribution map was generated using QGIS version 3.16.4 software. Geographic distribution data were gathered from Young (1977), Cavichioli (2000), Cavichioli and Takiya (2012), and information from specimen labels deposited in the DZUP collection.

Distribution. Brazil: Acre, Rondônia and Mato Grosso States.

Etymology. The specific epithet “ancora” is a Latin noun meaning “hook,” and refers to the distinctive shape of the male aedeagus, which presents a hook-like structure.

Remarks. Wolfniana ancora sp. nov. externally resembles W. limbatula due to its green body coloration with distinctive orange markings. However, these species differ in their specific color patterns: W. ancora sp. nov. exhibits a darker green ground color, with orange markings restricted to the lateral margins of the pronotum, whereas in W. limbatula these markings extend along both the anterior and lateral pronotal margins. The male genitalia of W. ancora sp. nov. and W. viridis are similar, but the two taxa can be easily differentiated by the pygofer shape-which in the former exhibits a distinct concavity along its median portion-and by the aedeagus bearing a characteristic hook-shaped process.

Occurrence map

Wolfniana viridis was previously known exclusively from the state of Amazonas but is herein newly recorded from the states of Acre and Rondônia. Wolfniana ancora sp. nov. is documented from the states of Acre, Mato Grosso, and Rondônia, occurring in sympatry with W. viridis at both the Catuaba Experimental Farm and the Antimary State Forest, two localities situated in the state of Acre. No additional distribution records were found for W. limbatula. Despite these new biogeographic data, the known geographic range of Wolfniana remains entirely restricted to the Amazon Basin. The spatial distribution of Wolfniana species (Fig. 6) reveals a substantial overlap with major protected areas in southwestern Amazonia, highlighting the critical role of conservation units in maintaining suitable habitats for these taxa.

DISCUSSION

We recognize the female of W. limbatula from French Guiana described by Young (1977). Although we did not have any female specimens of this taxon at hand, this species can be differentiated from W. ancora sp. nov. by the shape of the posterior margin of sternite VII, which is bluntly angulated in the former and medially excavated in the latter. Cavichioli (2000) included a female specimen from the state of Mato Grosso in the examined material, but its structures were not illustrated, and the female specimen described by Young (1977) was not listed. Due to the lack of available female material in our sample, we were unable to provide a redescription for the female of W. limbatula. Unfortunately, the female of W. viridis remains unknown.

Representatives of Wolfniana exhibit a highly homogeneous external morphology and male genitalic structure across species, with notable exceptions found only in the distribution of orange markings on the crown and pronotum, and in the overall shape of the aedeagus. This structural uniformity reinforces the cohesive nature of the genus despite the relatively small number of described species. Interspecific differentiation relies primarily on aedeagal variations-particularly in W. limbatula, whose aedeagus is conspicuously reduced relative to the anal tube. Nevertheless, these subtle yet consistent external characters remain highly valuable for species identification, especially given the broad geographic overlap observed in their distribution.

In the Brazilian Legal Amazon, where all Wolfniana species are distributed, multiple federal and state Conservation Units together cover a substantial portion of the biome. Protected landscapes account for nearly 22% of the Amazonian territory, with federal units spanning more than 610,000 km² and state-level units covering approximately 563,700 km² (Veríssimo et al. 2011). Several Wolfniana records originate from sites located within or adjacent to these managed boundaries. For instance, specimens of W. viridis and W. ancora sp. nov. were collected near the Rio Gregório Extractive Reserve, in the state of Amazonas. The type locality of W. ancora sp. nov. lies within the Cristalino State Park, in the state of Mato Grosso, while additional records for both species originate from the Antimary State Forest, in the state of Acre. Even smaller protected remnants, such as the Catuaba Experimental Farm in the state of Acre-an 860 ha research unit surrounded by highly fragmented landscapes-continue to provide critical long-term biodiversity data (PPBio 2012). These collective findings highlight the imperative role of protected areas as refugia for Wolfniana populations.

In contrast, Wolfniana limbatula exhibits a wider distribution encompassing the states of Acre, Rondônia, Mato Grosso, and Amazonas, as well as Ecuador and French Guiana. Its range partially overlaps with large-scale conservation initiatives, such as the Amazon Region Protected Areas Program (ARPA), which safeguards more than 59 million hectares of conservation units (Soares-Filho 2009).

Despite this partial intersection with protected lands, the distribution of Wolfniana also extends into zones characterized by intense deforestation, particularly in the states of Rondônia and Mato Grosso. These areas are deeply embedded within the “Arc of Deforestation”, where the expansion of cattle ranching, infrastructure, and intensive soy cultivation has driven catastrophic habitat loss and landscape fragmentation (Leal-Filho et al. 2025). Such anthropogenic pressures may compromise habitat continuity and threaten the long-term viability of these highly specialized insect populations.

The discovery and description of W. ancora sp. nov. from previously unrecorded localities emphasize the urgent importance of continuous, targeted field surveys throughout the Amazon Basin. Comprehensive and standardized sampling across altitudinal and spatial gradients remains vital to accurately assess the true species richness, evolutionary history, and geographic distribution of this endemic Neotropical genus.
