A new species of Vitalius (Araneae: Theraphosidae) from the Brazilian Cerrado

ABSTRACT

A new theraphosid species, Vitalius ornatissimus sp. nov., is described based on one male and one female from Brazil. The new species is distributed in the Brazilian states of Tocantins, Goiás, Distrito Federal, and the western state of Bahia, living in areas of the Cerrado biome. It is closely related to and resembles Vitalius chromatus (Schmidt, 2004) in appearance, with a general black coloration and whitish rings or stripes on the legs and palp in both sexes. With V. chromatus, it shares the presence of a row of spines on the distal-retrolateral edge of palpal tibia of male, but differs by the tibial apophysis and metatarsus I shape. Vitalius ornatissimus sp. nov. is the first species of Vitalius Lucas, Silva Jr & Bertani recorded exclusively in central Cerrado.

INTRODUCTION

To date, 1,114 species of theraphosids are known worldwide (World Spider Catalog 2024). Known popularly as tarantulas, and “aranha-caranguejeira” in Brazil, they are particularly speciose in the Americas (World Spider Catalog 2024). The genus Vitalius Lucas, Silva Júnior & Bertani, 1993 is endemic to Brazil, except for Vitalius paranaensis Bertani, 2001 that also occurs in Northern Argentina (World Spider Catalog 2024). Vitalius was revised by Bertani (2001) and a phylogenomic analysis using molecular data was carried out by Galleti-Lima et al. (2023). The genus has currently ten species: Vitalius sorocabae Mello-Leitão, 1923 (type species), V. australis Galleti-Lima et al., 2023, V. buecherli Bertani, 2001, V. chromatus (Schmidt, 2004), V. dubius (Mello-Leitão, 1923), V. lucasae Bertani, 2001, V. paranaensis (Bertani, 2001), V. restinga Bertani, 2023, V. sapiranga Bertani, 2023, and V. vellutinus (Mello-Leitão, 1923) (World Spider Catalog 2024). Species of the genus Vitalius are among the main large theraphosids in areas of Brazilian Atlantic Forest in the southeastern and southern Brazil (Bertani 2001, Galleti-Lima et al. 2023), and a new species was described recently from the restingas of the coast of the states of Sergipe and Bahia (Bertani 2023a). Two species have been recorded in the peripheric Cerrado biome, Vitalius sorocabae in transition areas with the Brazilian Atlantic Forest in the states of São Paulo and part of Minas Gerais and Paraná (Bertani 2001), and V. chromatus in transition areas with the Amazon and Caatinga biomes in the state of Maranhão (Bertani 2023b).

Herein, we describe the first species of Vitalius recorded exclusively in core Cerrado, a Brazilian savannah-like biome, from the States of Tocantins, Goiás, the Distrito Federal, and the western state of Bahia, Brazil.

MATERIAL AND METHODS

Measurements of large structures, such as appendage articles, carapace, abdomen and chelicera were made with a Mitutoyo digital caliper with an error of 0.005 mm, rounded up to two significant digits. Small structure measurements and images were obtained using a Leica LAS Montage and LAS 3D module mounted on a Leica M205C dissecting microscope with a DFC 450 camera attached. Legs and palp measurements were taken from the dorsal view of the left side. All measurements are in millimeters. Leg spines terminology follows Petrunkevitch (1925) and Bertani (2001). Structures of the left side of the specimens were chosen for descriptions. Male palpal bulb keel terminology follows Bertani (2000). Urticating setae terminology follows Cooke et al. (1972), the position of urticating setae on the dorsum of the spider’s abdomen follows Bertani and Guadanucci (2013).

Specimens from the following institutions were examined: Arachnid Collection, Universidade de Brasilia, Brasilia (DZUB); Instituto Butantan, São Paulo (IBSP).

Geographic coordinates were obtained with Google Earth^TM. The center of the municipality was used when the information on the label of the specimens was unavailable and indicated by square brackets. Original coordinates obtained from labels are indicated by rounded brackets. The species distribution maps were made with SimpleMappr (Shorthouse 2010).

Diagnosis. Females of Vitalius ornatissimus sp. nov. resemble those of V. sapiranga by the broad spermathecae with receptacles as large as spermathecae stalk (Figs 9-14). They differ by the sternum being slightly longer than wide. Males of V. ornatissimus sp. nov. resemble those of V. chromatus by the palpal tibia having a series of spines on the dorso-retrolateral distal edge (Fig. 7) and similar bulb shapes. They differ by the shape of the tibial apophysis with two convergent processes (Fig. 6), metatarsus I roughly straight (Fig. 8), and metatarsus I, when folding, touches the retrolateral side of the retrolateral process. Vitalius chromatus has the tibial apophysis with processes roughly straight, metatarsus I curved on its basal third and touches the apex of the retrolateral process when folded.

Distribution. Brazil, the Distrito Federal and the states of Tocantins, Goiás and part of the western Bahia (Figs 17-18).

Etymology. The specific epithet is from Latin, meaning adorned, decorated, ornate, and refers to the beautiful color pattern of the specimens.

Natural history. Vitalius ornatissimus sp. nov. occurs mainly in open (savannah) habitats, occasionally also in closed vegetation like gallery forest (Fig. 18). The males are found more frequently from November to March, months characterized by the rainy season in Cerrado, indicating the reproductive period.

DISCUSSION

Vitalius ornatissimus sp. nov. shares some characters of the genus Vitalius, as the same set of keels on the male palp bulb, more or less straight metatarsus I of male, shape of male tibial apophysis processes, absence of urticating setae type III in females (Bertani 2001). However, it has a short apical keel on male bulb, whereas all Vitalius and Nhandu Lucas species were known to have a more developed keel (Bertani 2001). More recently, two new species of Vitalius were described also having a short apical keel, which was considered a primitive condition (Bertani 2023a). Finally, a cladistic morphological analysis of the genus Lasiodora Koch included almost all Vitalius species and related genera, and recovered V. ornatissimus sp. nov. (cited as Vitalius sp. 1 in that paper) in a clade with the other Vitalius species (Bertani 2023b). In the topology obtained, V. ornatissimus sp. nov. is a sister species of Vitalius chromatus. This last species was transferred from the genus Nhandu in the same paper (Bertani 2023b). Actually, both species are very similar in appearance, mostly black and with large whitish rings or stripes on the legs and palp and can be easily confused, but they can be differentiated by the male tibial apophysis and the metatarsus shape of leg I.

Additionally, each species has a limited distribution, occurring in distinct and widely distant environments.
