Cyphomyiactia costai Artigas, Papavero & Serra, 1991 ( Figs. 2-3 View Figure 2 View Figure 3 )

Cyphomyiactia costai Artigas, Papavero & Serra, 1991: 62 ; Papavero, 2009: 92 (catalogue).

Original description is transcribed below:

“Face densely silvery-white tomentose. Hair of mystax white [ Fig. 2C View Figure 2 ]. Occiput [ Fig. 2D View Figure 2 ] golden tomentose at margins, brownish-black tomentose around foramen, with long, sparse, fine white pile bellow; dorsal occipital bristles yellowish. Scape brown, pedicel brownish-yellow, flagellum red-brown and white pollinose [ Figs. 2C, 2D View Figure 2 ]. Frons golden tomentose with a slender black stripe running from anterior ocellus to base of antennae.Vertex black.

Thorax blackish in ground color, with bluish reflections [ Fig. 2B View Figure 2 ]. 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. Lateral margins of antepronotum silvery-white tomentose. Postpronotum brown- Wings [ Fig. 2F View Figure 2 ] hyaline, slightly fumose along veins. Halteres yellow.

Abdomen [ Figs. 2A, 2B, 2E View Figure 2 ] blackish in ground color,with blue shine. Hairs of abdomen white. Tergites 3-4 silvery-white tomentose spots dorsolaterally [ Fig. 2E View Figure 2 ].

Holotype female. BRAZIL, Goiás, Goiânia (Campinas), 1935 (Borgmeier & Souza Lopes), in the MZUSP.”

Addenda to the holotype female description: Total length, excluding antenna, 10.6 mm; length of wing, 8.8 mm; greatest width of abdomen, 3.4 mm. 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 View Figure 2 ); 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 View Figure 2 ): Cell c wide; r₅ closed, with short stalk; m₃ widening posteriorly; cu p with short stalk; anal lobe wide. Legs ( Figs. 2 View Figure 2 A-2C, 2E): Entirely dark-brown, with dark-brown setae; tarsi with golden vestiture.

Label transcript: “Campinas, Goyaz [Goiás], Borgmeier et. S. Lopes, XII.[1]935 / [handwritten] Cyphomyiactia cyphomyioides , gen.n. sp. n. Artigas, Papavero & Serra / [red label] HOLOTYPE Cyphomyiactia costai , det. L.A. 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 View Figure 3 A-3C): Anterior margin of sternite VII sinuous ( Fig. 3A View Figure 3 ); hypogynium almost hemispherical, with hypogynial valves continuous with lateral margins of the sclerite ( Fig. 3C View Figure 3 ); smooth median protrusion between hypogynial valves ( Fig. 3C View Figure 3 ); smooth retraction on anterior margin ( Fig. 3C View Figure 3 ); hypogynium softly setate posteriorly. Three spermathecae ( Fig. 3B View Figure 3 ), 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 View Figure 3 ); spermathecal ducts opening independently at the bursa; genital fork U-shaped, arms anteriorly thick, posteriorly truncate, divergent ( Fig. 3B View Figure 3 ). Eggs brown and oval.

Male ( Figs. 3 View Figure 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 View Figure 3 ). Gonocoxites free, with setae near median margin basally ( Fig. 3D View Figure 3 ); 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 View Figure 3 ). 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 View Figure 3 ). Phallus strongly arched laterally (towards gonocoxal apodemes), protruded mediodorsally, in lateral view ( Fig. 3G View Figure 3 ); moderate dilation proximal to the prongs ( Fig. 3G View Figure 3 ); apex of phallus with three short prongs ( Fig. 3H View Figure 3 ); lateral ejaculatory processes wide ( Fig. 3I View Figure 3 ).

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.).
