INTRODUCTION
Artigas, Papavero & Serra (1991) proposed the genus Cyphomyiactia to include an undescribed Brazilian species, Cyphomyiactia costai Artigas, Papavero & Serra, 1991, because of its singular morphology.The generic description was based on a single female specimen collected in Goiás state.
Cyphomyiactia costai possesses a relatively wide face and an evenly convex, first flagellomere prolonged into a filiform process; the abdomen is very wide; short, and cup-shaped.Due to the overall coloration, the body being blackish with blue reflections and with a golden tomentose occiput, these robber-flies resemble stratiomyids of the genus Cyphomyia Wiedemann (Artigas, Papavero & Serra, 1991).
In this work, the male of Cyphomyiactia costai Artigas, Papavero & Serra, 1991 is described and illustrated for the first time.New records are provided from Bahia and Maranhão states, Brazil.The holotype is illustrated, as well as structures of male and female terminalia.

MATERIALS AND METHODS
In the present study, we examined specimens housed at INPA -Instituto Nacional de Pesquisas da Amazônia, CEIOC -Coleção Entomológica do Instituto Oswaldo Cruz, and CZMA -Coleção Zoológica do Maranhão, Universidade Estadual do Maranhão, Caxias, Maranhão, Brasil, as well as the holotype of C. costai housed in the Museu de Zoologia da Universidade de São Paulo (MZUSP) collection.
Dissected terminalia were treated in hot 10% KOH for varying periods of time, washed in water, subsequently treated in acetic acid and finally examined in excavated slides in glycerin.Illustrations of the terminalia were prepared using Adobe Illustrator CS5 software.After examination and illustration, the detached parts were placed in microvials containing glycerin and the vials were pinned with their respective specimens.Images were taken with a ZEISS AxioCam Mrc5 digital camera attached to a Zeiss Discovery V20 Stereomicroscope, using the lighting methods described by Kerr et al. (2008).Focus stacks of photos of asilid specimens were combined using CombineZP (Hadley, 2010).
Label data is cited in full, with the original spellings, punctuations, and dates.Information presented within square brackets -"[ ]" -is complementary data not included on the labels.Data for the same specimen but from different labels are separated by slashes ().

Remarks:
The specimen deposited in MZUSP did not bear an explicit label clarifying its name-bearing status.Apart from the original specimen label, there was only a handwritten identification label that read "Cyphomyiactia cyphomyioides gen.n. sp.n.Artigas, Papavero & Serra".Given that the morphology and sampling data of this specimen agree with those cited by the authors in the original description, and that there was no other specimen mentioned for the species in the original work, it is sensible to assume that "C.cyphomyioides" is an unavailable manuscript name and that this specimen is indeed the holotype of C. costai (N.Papavero, pers. comm.).
Although Cyphomyiactia's singular compactness cannot be identified in any other group within the Atomosiini, its spermathecal disposal greatly resembles that of Hybozelodes lucidus (Hermann, 1912), as well as the shape of antennae, the bluish reflections of thorax and abdomen, and the length of the lateral lobes of hypoproct of the male.These characters could indicate a closer relationship between the monotypic genus Cyphomyiactia and Hybozelodes Hermann, 1912.BRASIL, xi. 1963, Alvarenga e Werner (1 male CEIOC).Distribution (Fig. 1): BRAZIL (Maranhão, Bahia, Goiás, Mato Grosso).
