The Asilidae are voracious predatory flies, popularly known as assassin flies, robber flies, among other names (Fisher, 2009). There are 14 subfamilies, 560 genera and 7,531 valid species in the world (Dikow, 2009; Pape et al., 2011). The Neotropical region holds 11 subfamilies, 217 genera and 1,576 species (Papavero, 2009). In Brazil, 101 genera and 466 valid species were recorded (Lamas & Camargo, 2023), of which only three species are reported in the state of Tocantins, namely Cerozodus ayalai Camargo, Vieira & Rafael, 2022 by Camargo et al. (2022), Mallophora atra Macquart, 1834 by Artigas & Angulo (1980) and Ommatius exilis Curran, 1928 by Papavero (2009).

Cerozodus Bigot, 1857 is allocated in subfamily Asilinae. The genus was proposed as a monotypic for Asilus nodicornis Wiedemann, 1828. Then, a new species was described, Cerozodus brachylobusVieira, Rafael & Limeira-de-Oliveira, 2013. The genus was recently reviewed by Camargo et al. (2022), who presented in detail the taxonomic history, redescription and photographs of the holotype, as well as the description of two new species, Cerozodus ayalai Camargo, Vieira & Rafael, 2022 and Cerozodus platylobus Camargo, Vieira & Rafael, 2022. At the moment, only four species are known and the genus has not been registered outside Brazil. There are records of occurrence for the Northeast (Maranhão), North (Tocantins), Midwest (Goiás, Mato Grosso, Mato Grosso do Sul) and Southeast (São Paulo) Regions. Here, we describe a new species of Cerozodus for Brazil, present the second record of the genus for the North Region of Brazil, and provide the first occurrence records of five genera and 12 species for the State of Tocantins and an updated list of records.

MATERIAL AND METHODS

Origin of material and deposit. The specimens analyzed were obtained by examining the material deposited in the Coleção de Entomologia da Universidade Federal do Tocantins, Porto Nacional, Tocantins (CEUFT), and were collected in eight municipalities in the State of Tocantins, namely: Araguaína, Brejinho de Nazaré, Monte do Carmo, Novo Acordo, Palmas, Pium, Porto Nacional and Wanderlândia (Fig. 1). All specimens are deposited in CEUFT, with the exception of the holotype and one paratype of Cerozodus inesperatus sp. nov. deposited at Instituto Nacional de Pesquisas da Amazônia, Manaus, Amazonas (INPA).

Identification. To identify the species, papers with original descriptions, keys and reviews were consulted (Carrera, 1945, 1959; Artigas & Angulo, 1980; Pamplona & Aires, 1999; Scarbrough, 2003, 2008; Papavero et al., 2009; Vieira et al., 2010, 2012, 2013; Castro et al., 2016), in addition to photos of type material from the Museum für Naturkunde, Berlin, Germany (MfN), and the Museu de Zoologia da Universidade de São Paulo, São Paulo, Brazil (MZUSP). The dissection of the terminalia followed the protocol of Vieira & Rafael (2014). Terminology follows Cumming & Wood (2017).

Image acquisition and data presentation. Images were obtained using a LEICA MC120 HD digital camera coupled to a LEICA M165 C stereomicroscope. Photographs of the body (dorsal and lateral habitus) and head (frontal and lateral views) were taken for each species. Photos were edited with Adobe Photoshop CS6 software, version 22.0.0.35. The plates were elaborated using Adobe Illustrator 2021 software, version 25.2.1.236.

The information contained in the labels was written in full in the material examined. There was the use of commas to isolate different information. Data presented in square brackets is additional information that is not present on the labels. Slashes (/) were also used for data from the same specimen with separate labels. An asterisk indicates new distribution records.

Here, the Asilinae was divided into groups of genera as proposed by Artigas & Papavero (1997), namely: Asilus group; Efferia group; Eicherax group; Glaphyropyga group; Lecania group; Mallophora group and Proctacanthus group. These groups are commonly used to simplify species identification. Furthermore, The New World species of Ommatius (Ommatiinae) are divided into eight species groups [ampliatus and holosericeus (holosericeus complex), costatus, hanebrinki, lucidatus, normus, pumilus and tibialis] (Scarbrough, 1990, 1993, 2000, 2002, 2008; Scarbrough & Perez-Gelabert, 2006).

Etymology. inesperatus from Latin, refers to something unexpected.

Distribution. State of Tocantins, Brazil.

Biology/phenology. The specimens were collected in the district of Taquaruçu, a tourist region of Palmas, capital of Tocantins. It is a mountainous region, with valleys, plains and cliffs with elevations ranging from 34 to 960 m (Seplan, 2003). This area has a rich vegetation, with typical cerrado, gallery forest and riparian forest. The climate is semi-humid tropical, with seasonally well-defined rainfall periods, with a hot and dry winter (May to September) and a rainy season (October to April) (Marcuzzo & Goularte, 2013). The specimens were found in riparian forests of an Environmental Protection Area called Serra do Lajeado, being captured with a Malaise trap both in the dry and rainy seasons. The data obtained here corroborate the information presented by Camargo et al. (2022), in relation to the distribution patterns of the other species of the genus.

Type material. Holotype ♂, BRASIL, TO[CANTINS], Palmas, Taquaruçu, Faz[enda] Encantada, 10°14’41.79”S; 48°7’22.79”W, 15-22.IV.2012, Malaise, Krolow, T. K. & Lima, I. L. H. (INPA) / Holotype Cerozodus inesperatus det. Montanuci, P. S.B, 2021. Paratypes. Same data as holotype except: 26.X-02.XI.2012 (♂ CEUFT / 004816); 03-10.VIII.2012 (♀ INPA); 07-14.IX.2012 (♀ CEUFT / 004819).

Discussion. Cerozodus was recently reviewed by Camargo et al. (2022) and currently has four valid species. Cerozodus inesperatus sp. nov. runs to step 2 of the key by Camargo et al. (2022), from this point it can be easily distinguished from the other species by presenting the hypandrium with a straight margin, without projection (Fig. 15), and its conspicuous tongue-shaped projection in this species is found on the sternite 8 (Figs 12, 17) and not on the hypandrium as in other species of the genus.

Eraxasilus pruinosus is very close to E. acuminatusCarrera, 1959, but they can be distinguished by the shape of the hypandrium. In E. pruinosus the hypandrium is not acuminate, but curved and smooth, while in E. acuminatus the hypandrium has a small acuminate projection covered with small setae (Carrera, 1959).

This species is very close to Glaphyropyga himantocera (Wiedemann, 1828), from which it is distinguished by the patterns of tomentum on the scutum and pleura, the absence of setae on the scutellum and the dark brown spot on the wings. This species is characterized by having a yellow scape and pedicel, a scape longer than pedicel (Figs 38, 39), a short stylus with a small sensorial element at the apex; pleura with a dark vertical spot on the anterior part and yellow wings with a dark spot on the subcostal cell (Figs 36, 37), which does not extend to R₄ (Carrera, 1945).
