Pleura with mixed silvery-white and golden-brown tomentum in some areas. Antepronotum predominantly golden tomentose with a brownish-black stripe on the anterior border and yellow hairs.

Head: Eyes greenish; occiput silvery-golden-pollinose on ventral 1/4. Thorax: Postpronotum with mixed brownish-golden and silvery-white tomentum, setae brown and white ( Fig. 2C ); anepisternum with mixed silvery-white and golden-brown tomentum; 3 long and strong anepisternal macrosetae, among others; anepimeron dark-brown; 3 postalar setae (not 1 postalar + 3 on “posterior callus”). Wing ( Fig. 2F ): Cell c wide; r₅ closed, with short stalk; m₃ widening posteriorly; cu p with short stalk; anal lobe wide. Legs ( Figs. 2 A-2C, 2E): Entirely dark-brown, with dark-brown setae; tarsi with golden vestiture. Label transcript: “Campinas, Goyaz [ Goiás ], Borgmeier et. S.

Cezar, 2014.” Holotype condition: Pinned; well preserved; lacking right antenna, anepisternal and postalar setae on the left side, and left wing. Female, additional specimen: Total length, excluding antenna, 9.2 mm ; length of wing, 7.1 mm ; greatest width of abdomen, 3.2 mm . Female terminalia, additional specimen ( Figs. 3 A-3C): Anterior margin of sternite VII sinuous ( Fig. 3A ); hypogynium almost hemispherical, with hypogynial valves continuous with lateral margins of the sclerite ( Fig. 3C ); smooth median protrusion between hypogynial valves ( Fig. 3C ); smooth retraction on anterior margin ( Fig. 3C ); hypogynium softly setate posteriorly. Three spermathecae ( Fig. 3B ), occupying abdominal segments 4-8; reservoirs cylindrical, disposed from a wider elliptical spiral going to an inner round and more sclerotized spiral distally ( Fig. 3B ); spermathecal ducts opening independently at the bursa; genital fork U-shaped, arms anteriorly thick, posteriorly truncate, divergent ( Fig. 3B ). Eggs brown and oval. Male ( Figs. 3 D-3I): Total length, excluding antenna, 10.6 mm ; length of wing, 7.6 mm ; greatest width of abdomen, 3.2 mm . Similar to female except for: postalar callus with 4 macrosetae; antepronotum predominantly with dark-brown setae; anepimeron with white and brown tomentum. Male Terminalia: Hypopygium inconspicuous in both dorsal and lateral views, hidden under a strongly-convex cup-shaped abdomen. Hypandrium subtriangular, wider than long, with blunt posterior margin, and a median concavity on anterior margin ( Fig. 3D ). Gonocoxites free, with setae near median margin basally ( Fig. 3D ); gonocoxal prolongations blunt, smoothly curved inwards, with strong medially-directed setae near apex; gonostyli reduced, round, attached to the dorsal base of gonocoxites ( Fig. 3D ). Lateral lobes of hypoproct subquadratic (abruptly blunt and parallel-sided), in dorsal view; lateral lobes long, extending beyond the apex of gonocoxal prolongation, and diverging posteriorly. Cerci free, subtriangular, slightly longer than wide, distant from each other ( Figs. 3E, 3F ). Phallus strongly arched laterally (towards gonocoxal apodemes), protruded mediodorsally, in lateral view ( Fig. 3G ); moderate dilation proximal to the prongs ( Fig. 3G ); apex of phallus with three short prongs ( Fig. 3H ); lateral ejaculatory processes wide ( Fig. 3I ).

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. ).
