A new species of pincer wasps of Deinodryinus Perkins (Hymenoptera, Dryinidae) from oceanic archipelago of Fernando de Noronha, Brazil

. The first record of the genus Deinodryinus Perkins and the description of a new species Deinodryinus noronhensis sp. nov. from oceanic archipelago of Fernando de Noronha (Brazil) are performed. Additionally, an illustration of the new species and a modified key are presented together with a discussion on the Deinodryinus records for the northeastern region of Brazil.

The Dryinidae fauna of Brazil was neglected for many years, making many regions still unexplored: one of them is the archipelago of Fernando de Noronha.Recently the Hexapoda fauna of the Fernando de Noronha archipelago was studied by Rafael et al. (2020) and listed 453 terrestrial species and morphospecies.In this study about 50 specimens of Dryinidae were collected and identify in family level and reported the first record of this taxon from archipelago (Rafael et al., 2020).Two specimen of Dryinidae belonging to Deinodryinus genus and recognized as a new species.Here is presented the first records of Dryinidae species and described of new species for science.
In the descriptions, the following abbreviations are used: POL, refers to the minimum distance between the inner edges of the lateral ocelli; OL, refers to the minimum distance between the inner edges of the lateral ocellus and the median ocellus; OOL, refers to the minimum distance from the outer edge of a lateral ocellus to the eye inner margin; OPL, refers to the minimum distance from the posterior edge of a lateral ocellus to the occipital carina; TL, refers to the minimum distance from the posterior edge of an eye to the occipital carina.
Label information was transcribed as follows: a backslash (\) indicates different lines on the label.
Colour images were obtained using a LEICA® DFC295 digital camera attached to the stereoscopic microscope Leica M125 and processed with Zerene Stacker software (1.04 version build).Scanning electron photomicrographs (SEM VEGA3 TESCAN) were made in the Center of Electron Microscopy of the Universidade Federal do Paraná.Figures were prepared using Adobe Photoshop (version 11.0).

Etymology:
The name noronhensis is a Latinized word meaning 'from Archipelago Fernando de Noronha' , where this species has been collected.
Remarks: Among the Neotropical species of Deinodryinus, D. noronhensis sp.nov. is close to D. diaphanus Olmi (1984) by the body totally testaceous, at most with petiole black, head granulated, without areolae or carina, notauli almost reaching posterior margin of mesoscutum.However, the new species differs from it by the following characters: head with face with little pilosity; vertex granulate, except ocellar triangle smooth (in D. diaphanus, head with vertex punctate, unsculptured among punctures); fore wing with two dark tranversal bands (in D. diaphanus fore wing hyaline); stigmal vein of fore wing with 2r-rs shorter than 3Rs&4Rs (in D. diaphanus with 2r-rs longer than 3Rs&4Rs).

DISCUSSION
Deinodryinus species are recorded in several South American countries including several Brazilian states (Olmi & Virla, 2014;Martins, 2015;Martins & Olmi, 2021).In Brazil, specifically for the Northeast region, nine species are known and distributed in four different states (Table 1): five of them recorded for Bahia, two for Pernambuco, one for Ceará and one for Maranhão (Olmi & Virla, 2014).
Little knowledge of the distribution of Dryinidae species in Brazil is due to the fact that there has never been a specialist in this group of wasps for this country and most of the known species were sent abroad and studied by Dr. Massimo Olmi.
The discovery of D. noronhensis sp.nov.shows how much effort is needed to expand the knowledge of the Dryinidae fauna in almost regions from Brazil.The description of the first species of Dryinidae for the Fernando de Noronha Archipelago and the new records of other Hexapoda presented by Rafael et al. (2020) shows how important knowledge about the invertebrate fauna is to maintain this conservation area so that more species of Dryinidae and other insects in this area can be recognized.
