Shimizu, So, 2016, Recognition of the genus Habrocampulum Gauld, 1976 (Hymenoptera: Ichneumonidae: Anomaloninae) from Japan, with a new combination and a key to the species, Zootaxa 4103 (3), pp. 283-288 : 285

Genus Habrocampulum Gauld, 1976

Habronyx (Habrocampulum) Gauld, 1976: 38 . Type-species: Anomalon biguttatum Gravenhorst, 1829: 642 . Habrocampulum Schnee, 1989: 245 . New status, raised to genus from subgenus.

Diagnosis. This genus can be distinguished from other genera of Anomaloninae by the following combination of character states: (1) eyes bare; (2) lower margin of clypeus with a median apical tooth ( Figs 2, 4 ); (3) frons with a median longitudinal carina ( Figs 2, 3 ); (4) occipital carina complete ( Figs 3–5 ); (5) mandible with two distinct teeth ( Fig. 2 ); (6) upper margin of pronotum with a weak longitudinal impression ( Fig. 5 ); (7) antero-ventral corner of pronotum with a tooth ( Fig. 5 ); (8) mesoscutum rounded, and its anterior margin with a weak concavity ( Fig. 5 ); (9) notauli present ( Fig. 5 ); (10) epicnemial carina present, its upper end reaching front margin of mesopleuron at the level of lower end of pronotum ( Fig. 5 ); (11) posterior transverse carina of mesosternum interrupted at the front of mid coxa; (12) scutellum convex ( Fig. 5 ); (13) postscutellum longer than its width ( Fig. 6 ); (14) fore wing with CI=0.8–1.1; (15) 2rs-m on fore wing straight; (16) hind wing with Cu1; (17) fore coxa smooth, without carina or its vestige; and (18) mid tibia with two spurs.

Distribution. Nearctic ( Canada and United States of America) and Palaearctic ( Belgium, Czech Republic, Czechoslovakia, Finland, France, Germany, Latvia, Netherlands, Poland, Russia, Spain, Sweden, and United Kingdom) regions ( Yu et al. 2012). New to Japan.

Bionomics. Two noctuid moths ( Agrotis segetum and Panolis flammea ), four geometer moths ( Bupalus piniarius , Caripeta divisata , Macaria granitata , and M. liturata ), and a single lasiocampid moth ( Dendrolimus pini ) have been reported as hosts of H. biguttatum ( Yu et al. 2012) .

Remarks. This genus is closely related to Aphanistes , Barylypa , and Habronyx based on morphological characteristics ( Gauld 1976). Japanese species of Habrocampulum have previously been misidentified as Aphanistes , because they are closely related and have common characteristics (e.g., anterior margin of mesoscutum with concavity and frons with a median longitudinal carina), but Habrocampulum can be distinguished from Aphanistes and the other Japanese genera of Anomaloninae by the following update key.
