Oxypoda (Baeoglena) nova BERNHAUER, 1902: 180 f.

Oxypoda (Mycetodrepa) giachinoi PACE, 2001: 131 f.; syn. nov.

Type material examined: Lectotype [dissected prior to present study], present designation: “ nova Brnh , Türkei, Merkl / Chicago NHMus, M. Bernhauer Collection / Lectotypus Oxypoda nova Bernhauer / Oxypoda nova Bernhauer , det. V. Assing 2018” ( NHMW) . Paralectotypes: 1 ex. [abdomen missing]: “ Saj / nova Brh. Bosnien, Type. / Chicago NHMus, M. Bernhauer Collection ” ( FMNH) ; 1 ex. [abdominal apex missing]: “[locality illegible] / nova Brh. Bosnien, Type. / type / ex coll. Skalitzky / Typus Oxypoda nova M. Bernhauer / Oxypoda nova Bernhauer , det. V. Assing 2018” ( NHMW) ; 1: “Dalmatia, Reitter. / praecox Er ?, nach Smlg Epp / nova Brh Type / Chicago NHMus, M. Bernhauer Collection ” ( FMNH) .

Comment: The original description of O. nova is based on an unspecified number of syntypes from “ Bosnien (... Sarajevo ...), Dalmatien und der Türkei ” and from “ Italien und Spanien ” ( BERNHAUER 1902). Thus, as can be inferred from the revised distributions, the type material includes at least two, possibly even three, or even four species. Four specimens qualifying as syntypes were located in the Bernhauer collection and in the collections of the NHMW. A syntype from Turkey, the only male in fairly good condition among them, is designated as the lectotype.

PACE (2001) described O. giachinoi based on a male holotype and female paratype from “ Grecia, nom. Fthiótida, O. Oxià, str. Gardìki–Gramméni Oxià” and erroneously assigned the species to the subgenus Mycetodrepa THOMSON, 1859 . The illustrations of the aedeagus leave no doubt that O. giachinoi is conspecific with O. nova .

Diagnosis: Winged species of mostly reddish coloration.

: median lobe of aedeagus ( Figs 23–26 ) of distinctive shape, relatively large, approximately 0.45 mm long; ventral process strongly curved in lateral view and apically concave in ventral view; crista apicalis very small; crista basalis very narrow; apical lobe of paramere ( Fig. 27 ) relatively short, barely half as long as basal portion; basal portion of paramere ( Fig. 27 ) with distinctive dark structure and relatively short apical lobe.

: spermatheca ( Fig. 28 ) of variable shape, relatively small, with bell-shaped apical cuticular invagination.

Distribution and natural history: The revised distribution of O. nova is remarkably discontinuous ( Maps 1 , 5 ). In Italy, it is confined to the extreme south (Calabria). This population is separated from the geographically closest populations in the Balkans by the Adriatic and Ionian Seas or by approximately 1000 km on land (North Croatia). In the Balkans, it is distributed in the northwest ( Croatia, Bosnia-Herzegovina, Montenegro) and in the southeast (Northeast Greece, Bulgaria); moreover, there is an enclave in the south of mainland Greece. These regions are separated by the distributional range of O. kuehnelti . From the southeastern Balkans, the record from Morocco).

range continues along North Anatolia eastwards to Gümüşhane and overlaps with that of O. caucasica . The only plausible explanation of this remarkable distribution pattern is interspecific competition with other Baeoglena species ( O. fusina , O. kuehnelti , O. rectacia , possibly also O. caucasica ).

The examined material was mostly sifted from leaf litter and roots in various forest (deciduous, coniferous, mixed) and bush habitats, but was also found in swamps and on stream banks. The altitudes range from 400 to 2070 m. The specimens were found in March (4 records), April (28), May (35), June (12), July (9), and August (3). The respective number of records most likely reflects the collecting activity more than the actual phenology of the species.
