Diagnosis. This is a typical Stackelbergiella ( Jaschhof & Jaschhof 2013: 355f.), distinguished from both S. hordei and S. rickebasta in that the gonocoxal synsclerite has a small, U-shaped emargination ventrally, which is flanked by inconspicuous, microtrichose protrusions ( Fig. 16 View FIGURES 16–17 , ↓ 1). As another distinction, the base of the aedeagal apodeme is just slightly thickened, not T-shaped ( Fig. 17 View FIGURES 16–17 , ↓ 2). Females and preimaginal stages of the new species are unknown.
Other male characters. Body size 1.2 mm. Head. Flagellomeres 15. Neck of fourth flagellomere 0.8 times the length of node. Palpus short, 2 setose segments; basal segment globular, half as long as napiform apical segment. Wing slightly longer than body, 2.8 times longer than wide. Legs. Claws thin, sickle-shaped, with single large tooth basally. Genitalia. Gonocoxae with sparse setae ventrally; pointed ventroposteriorly; with faint, dark pigmentation around the emargination ( Fig. 16 View FIGURES 16–17 ). Gonostylus twice as long as broad, slightly bent, pointed apically; no apical spine ( Fig. 16 View FIGURES 16–17 ). Aedeagus including apodeme almost as long as gonocoxae; apex truncate or slightly concave ( Fig. 17 View FIGURES 16–17 ). A single pair of long, sclerotized parameres whose pointed apices are bent ventrally ( Fig. 17 View FIGURES 16–17 ).
Etymology. This new species is named after Tomáš Sikora, Ostrava ( Czech Republic), who in recent years exhibited his talents as a successful collector and careful student of mycophagous Cecidomyiidae , with a special focus on the fauna of the Czech and Slovak Republics. The Estonian specimen studied here of S. sikorai was detected by Tomáš and correctly identified as a new Stackelbergiella .
