Empidideicus ( Empidideicus) guguy Suárez , sp. nov.

( Fig. 9a–g View FIGURE 9 )

Type-material. Holotype 1♂ (DZUL-50897; pinned) and 6♀ paratypes (DZUL-50904) from SPAIN: Canary Islands, Güigüí , 27.9404ºN, - 15.823ºW, 6.IV.2024, A.J. Pérez, E. Jiménez & D. Lugo leg. GoogleMaps

Diagnosis. Using the key of Evenhuis et al. (2023) this species runs to Empidideicus hackmani François, 1969 but differs from it by having different male genitalia (i.e., epandrium obcordiform in ventral view, aedeagal bulb inverted cup-shaped, and longer and wider gonostylus). The combination of grey mesonotum without markings, yellow scutellum, long fork of veins M 1 -M 2, black abdomen, and greyish halter knob and stem rules out E. hispanus François, 1969 ( Spain), E. carthaginiensis Becker, 1907 ( Algeria, Egypt, Israel, Tunisia, Sudan), E. hungaricus Thalhammer, 1991 ( Hungary, Malta, Corsica, Crimea), and E. insularis Frey, 1958 ( Cape Verde).

Description

Male ( Fig. 9a View FIGURE 9 ). Length: 0.8 mm. Wing: 0.6 mm. Head: length as long as high in lateral view; eyes dichoptic, occiput and postgena black, yellow laterally; vertex black; frons black, with thin yellow margin, face yellow; tip of oral margin black; antennae black; scape short; pedicel subconical; first flagellomere suboval, as long as wide; second flagellomere cylindrical, longer than wide; postmentum yellow; clypeus black, longer than oral margin; proboscis black, 1.3× longer than head length; labrum black, as long as head height; palpus not evident.

Thorax: Mesonotum grey with yellow lateral marks extending from postpronotal lobe to postalar callus; scutellum yellow; mesonotum and dorsum of scutellum with short and yellow hairs; pleura bare, yellow with grey marks to on following: anterior half of anepisternum and katepisternum, basal half of anepimeron, katepisternum, and meron; halter stem and knob greyish.

Legs: Grey except posterior tip of femora yellow.

Wing ( Fig. 9b View FIGURE 9 ): elongate, length 2× width; hyaline; veins dark brown; costa ends slightly beyond end of R 4+5; vein Sc incomplete, ending slightly beyond the origin of Rs; R 4+5 slightly bowed at apical one-third; fork of veins M 1 –M 2 length 4× basal stalk length; vein M 1 curved toward wing margin; M 2 slightly curved downward at wing margin; cell dm open; CuP thin, straight to wing margin; anal cell open at wing margin; fringe of hair on posterior margin of wing homogenous in length, but becoming more sparse towards base.

Abdomen: All tergites black, with a posterior thin yellow margin, yellow hairs.

Terminalia ( Fig. 9c–f View FIGURE 9 ): Epandrium light brown basally, medially, and external median margin, but yellow on internal median margin and subapically, U-shaped in ventral view, darkly sclerotized apically. Epandrium subrectangular in lateral view, without apical process; gonocoxa in ventral view subrhomboidal, with cylindrical hyaline gonostylus, as long as gonocoxa; lateral arms of parameral sheath extending well beyond gonocoxa, slightly shorter than aedeagal bulb, flared apically; aedeagal bulge inverted cup shaped; aedeagal apodeme cylindrical, with two lateral rami as long as aedeagal apodeme.

Female. As in male except tibia yellow; yellow margins of tergites higher laterally, occasionally with black dots. Terminalia ( Fig. 9g View FIGURE 9 ): genital fork thin, U-shaped, lateral arms sinuous, sclerotized; three well developed spermatheca, ovoid, with wide papillate apex on apical one-fourth, sclerotized brown, wider than long, large hole apically; apical spermathecal duct thin and transparent, length subequal to sperm pump; sperm pump near spermathecal reservoir, transparent, not sclerotized apically or basally.

Etymology: The specific epithet is named for the Canarian aboriginal name of the type locality. It is treated as a noun in apposition.

Distribution: Gran Canaria (up to date, restricted to just one single locality).
