Holotype ♀ in NMBE, here designated, labelled ‘ RUSSIA Moscow (in Apartment) Stegobium paniceum leg. ix.1995 [print]; chromosomes = 5 strain lab culture e.p. iii.2002 Sitophilus granarius A. Timokhov, Moscow [print]; 1956 Baur [print]; Holotype ♀ Anisopteromalus quinarius sp. n. Gokhman & Baur lab. H.

Diagnosis, female. Head and mesosoma olive-green with slight bronze tinge in places, setae whitish, inconspicuous. Gena compressed, with a short carina near mouth margin ( Fig. 6 C). Flagellum almost filiform, first funicular segment subconical, basally about as broad as third anellus, provided with 1–2 rows of longitudinal sensilla. Scutellum projecting at level of anterior margin of dorsellum, in lateral view weakly curved. Forewing with setae on wing disc dark. Speculum bare, open below but sometimes closed in proximal part ( Fig. 5 B). Anterior plica of propodeum consisting of small deep pits, costula indistinct ( Fig. 6 E). Posterior margin of first gastral tergite curving backwards, not produced medially ( Fig. 5 H). Head breadth 1.24–1.51× metatibia length and 1.48–1.69× eye distance; head height 2.34–2.74× eye breadth; eye height 1.09–1.32× scutellum length; pedicel plus flagellum 1.63–1.97× eye height; mesosoma length 8.11–11.87× OOL; scutellum length 1.38–2.00× stigmal vein; metatibia length 1.67–2.25× marginal vein; gaster length 11.38–16.43× OOL.

Description, female. Antenna with scape testaceous, pedicel light brown, first and second anellus testaceous, rest of flagellum fuscous. Legs with tibiae yellowish testaceous or slightly infuscate in basal half.

Head 1.01–1.25× as broad as mesoscutum. POL 1.71–2.46× OOL. Eyes 1.45–1.64× as high as broad, separated by 1.12–1.35× their height. Malar space 0.40–0.53× eye height. Head in frontal view 1.13–1.26× as broad as high. Antenna with scape 0.68–0.85× as long as eye height. Combined length of pedicel plus flagellum 0.84–0.99× head breadth. First and second anellus strongly transverse, third conspicuous, about as long as or longer than first two anelli (shorter in Fresno strain).

Mesosoma 1.18–1.43× as long as broad. Mesoscutum 1.66–2.17× as broad as long. Hind margin of scutellum broadly rounded. Upper mesepimeron strongly narrowing below, reaching at most basal third of mesopleuron. Basal setal line complete. Costal cell with dorsal surface with a patch of setae in distal half and a single row of setae in proximal half, lower surface with a large patch of setae in distal half and two to three rows of setae in proximal part, costal setal line complete. Forewing disc thickly pilose. Marginal vein 1.09–1.90× as long as stigmal vein. Stigma variable in shape, from subcircular (Fresno strain) to subrectangular (MSU strain), large. Propodeum 0.40–0.52× as long as scutellum. Median carina fine, straight. Median area evenly reticulate with inner corner of anterior plica with slight and evenly reticulate depression. Nucha subglobose, not distinctly separated from rest of propodeum, smooth or weakly alutaceous.

Metasoma: Gaster 1.39–2.86× as long as broad, 1.23–1.67× as long as mesosoma, and 0.61–1.21× as long as mesoscutum. Posterior margin of second and third gastral tergite incised medially.

Etymology. The specific name ‘quinarius’ is derived from Latin and means ‘of five’. It refers to the haploid chromosome number, which is only five in this species. The name ‘quinarius’ is treated as a noun in apposition and does not change with gender.

Biology. Host preferences of this species contrast somewhat with those of A. calandrae . Specifically, it prefers to attack certain Anobiidae, for example Stegobium paniceum or Lasioderma serricorne; however, it can easily be reared (e.g. under laboratory conditions) on Sitophilus spp. (Dryophthoridae; see, e.g., Timokhov & Gokhman, 2003).

Distribution. Cosmopolitan.

Remarks. The females of A. quinarius sp.n. can be recognized by the characters given in the key and diagnosis. For the separation of males from A. calandrae , see ‘Remarks’ in that species description.
