NematusabbreviatusHartig, 1837: 205. Lectotype ♀ (GBIF-GISHym3181; here designated) in ZSM, examined. Type locality: Germany. Gymnonychus californicusMarlatt, 1896: 122-123. 11 possible ♀ syntypes (USNMENT00778445) in USNM, not examined. Type locality: Brockport, New York and Sacramento, California, United States. Synonymised with P. abbreviataby Benson (1958).
Similar species. Most easily confused with P. monogyniae, from which it differs by having pale pronotal angles (black in P. monogyniae), black clypeus (pale in P. monogyniae), and the valvula 3 with a distinct dorsoapical projection (absent in P. monogyniae) (Figs 66-67, 71-72). Males, which are extremely rare (we have seen one), are best recognised by examining penis valves (Figs 252, 256). See the Key for more details.
Geneticdata. Based on COI barcode sequences (only one specimen in BOLD), it forms its own BIN cluster (BOLD:ACV9937). The nearest neighbour (BOLD:AAG3540, P. melanocarpa) is 8.43% different. Based on nuclear data (one specimen; NaK), the nearest neighbour is 4.2% different (unidentified specimen DEI-GISHym84983 belonging to the ruficornisgroup).
Host plants. Pyrus communisL. ( Zocchi 1949, as Micronematus abbreviatus) and Pyrus spinosaForsk. ( Schedl and Ritzau 1995).
Distribution and material examined. West Palaearctic, (Nearctic). Specimens studied are from Germany and Greece.
