Oxypoda (Baeoglena) praecox ERICHSON, 1839

( Figs 1–9 , Maps 1–3 )

Oxypoda praecox ERICHSON, 1839: 148 f.

Type material examined: Holotype: “ Austria. Schüpp / praecox Er. / 5535 / Syntypus Oxypoda praecox Erichson, 1839 , labelled by MNHUB 2018 / Syntypus Oxypoda praecox Erichson , rev. V. Assing 2018” ( MNB).

Comment: The original description is based on an unspecified number of syntypes from “ Austria ” ( ERICHSON 1839). Only a single female syntype was located in the historical collection of MNB. The specimen is conspecific with the previous interpretation of this species.

Oxypoda praecox previously had two junior synonyms, which are now synonyms of O. fusina . For details see the comment in the section on O. fusina .

records (white circles), and selected literature records (grey circles).

Diagnosis: Small wing-dimorphic species. Coloration mostly reddish-yellow, more rarely darker or with a darker abdomen.

: median lobe of aedeagus ( Figs 1–7 ) 0.31–0.34 mm long; ventral process apically truncate in lateral view; internal sac with pair of short apical spines, without filiform apico-ventral structure; apical lobe of paramere ( Fig. 8 ) very long, approximately three-fourths as long as basal portion; basal portion of paramere ( Fig. 8 ) without distinct modifications, without dark structure.

: spermatheca ( Fig. 9 ) with bell-shaped apical cuticular invagination.

Distribution and natural history: In the course of the present revision, male-based records were seen from Finland, Germany, Austria, the Czech Republic, Slovakia, Hungary, and Bulgaria. Additional female-based records from Romania, North Greece, and Siberia are doubtful. In North, Central, and East Europe, the species has – most likely reliably – been reported from Switzerland, Denmark, the Netherlands, Norway, Sweden, Poland, Estonia, Lithuania, and the Russian North and Central European territory ( HORION 1967, SCHÜLKE & SMETANA 2015). The species is not listed for Great Britain in the Palaearctic Catalogue, but was reported from South England by WILLIAMS (1990). For a selection of additional, probably reliable records see BARANOWSKI & SÖRENSSON (1978), BÜCHE (1994), GRUNDMANN (1991), HANSEN (1964), JÖRGER (1924), KOCH (1978), KÖHLER (1988), LOHSE (1967), ROSE (2000), and SMOLEŃSKI (1997).

Previous records from other more southern and western regions must be considered highly doubtful and are most likely based on misidentified material. In Central Europe, O. praecox is not uncommon in the northeast, but becoming increasingly rare towards the west. This, the near absence of records from South Europe, and the records from Siberia (if they in fact refer to O. praecox ) suggest that the species may be a Siberian faunal element. Previous records from East France (exclusive of Corsica) may refer to O. praecox or O. fusina ; those from Southwest France ( TRONQUET 2006) refer to O. fusina . The revised distribution is illustrated in Maps 1–3 .

The species has been collected in a wide range of both moist and dry habitats: in moist debris on shores or banks of standing and running waters, in sand pits, forests, grasslands, urban habitats (dumps, railroad tracks), from leaf litter, nests of mice, rats, moles, and badgers, from ant nests, hollow trees, and straw of field barns ( HORION 1967, KOCH 1978, and material examined). According to LOHSE (1989), O. praecox is regionally common in pine forests in East Germany. It was also observed to be abundant in coastal dune habitats of islands in Northwest Germany ( ROSE 2000).

The examined material with dates specified on the labels was collected practically throughout the year, with a maximum in spring: January (1 record); February (3); March (7); April (15); May (21); June (10); July (5); August (4); September (4); October (4); November (3); December (1).
