See Microgaster archboldensis  above for details on how these two species are distinct from each other and from all other known Microgaster  in North America.


Female. Head and mesosoma black; metasoma with T1-3 reddish-orange, T4+ and hypopygium orange-yellow; all legs mostly reddish-orange (except for posterior 0.2-0.1 of metatibia, metatibial spurs and metatarsus which are dark brown to black); wings strongly infumated, pterostigma and veins dark brown to black. Flagellomere with three rows of placodes. Scutoscutellar sulcus usually with 7-8 costulae (rarely with 5-6). Hypopygium pleated. Tarsal claws pectinate. Body measurements (mm). Body L: 4.6 (4.6-5.2); fore wing L: 4.9 (4.8-5.3); ovipositor sheaths L: 0.85 (0.86-0.94); metafemur L/W: 1.56/0.46 (1.50 –1.63/0.50– 0.54); metatibia L: 1.82 (1.82-1.98); metatibia inner/outer spurs L: 0.66/0.41 (0.70 –0.78/0.46– 0.50); first metatarsus segment L: 0.83 (0.80-0.98); F1/2/3/14/15/16: 0.40/0.40/0.40/0.19/0.18/0.20 (0.38 –0.43/0.39–0.45/0.40–0.44/0.19–0.20/0.16/0.19– 0.20).

Male. As female.

Molecular data.

Two sequences, one of them barcode-compliant, representing BIN BOLD:AAZ7881 in BOLD.


United States: FL, GA. Only known from two localities in Florida and one in Georgia.


Derived from Greek, ‘syntopic’ meaning 'from the same place’, a term used in Zoology to reference two or more related species which can occupy the same locality/habitat, and could possibly hybridize or even be sister species (see explanation of the concept in Rivas 1964). The name refers to this species being syntopic with Microgaster archboldensis  (at least around Archbold Biological Station, where both species were collected, sometimes on the same date and by the same Malaise trap).


See Notes above (under Diolcogaster ichiroi  ) for more details on the conservation value of these species.
