Tymmophorus suspiciosus ( Brischke 1871, Bassus ) (stat. rev.)

Diagnosis. Fore wing length 3.5–4.5 mm. Antenna of both sexes with 18–19 flagellomeres. Mesoscutum and mesopleuron entirely smooth and shining, mostly unsculptured, sometimes with some weak punctures along anterior margins. Propodeum with a full set of strong carinae enclosing basal, lateral and petiolar areas, the areas with rugose sculpture. Tergite 2 0.9–1.2 times as long as wide. Metasoma in females dorsoventrally depressed and gradually tapered, widest part of metasoma at apex of third or base of fourth segment.

Colouration of females. Antenna usually bright orange, at least ventrally. Head and mesosoma black, face with yellow along inner orbits, yellow or brown on clypeus and mouthparts, yellow on hind corner of pronotum, tegula, and sometimes upper mesepimeron; without yellow shoulder marks, scutellum black. Legs orange, coxae basally black with a yellow apex, fore coxa sometimes entirely yellow, trochanters yellow; femora orange, often dark basally; hind tibia and tarsus orange. Metasoma with orange markings on all of or apex of tergite 2, usually all of tergites 3 and 4, and usually part of 5.

Colouration of males. As in females but with yellow ventrally on antenna, face entirely yellow, yellow marks often on lower propleuron and sometimes anteriorly on mesosternum. Fore and mid coxae all and hind coxa mainly yellow. Metasoma as in female, or with orange colouration extending further back.
