CF392644B26958BF9A70CEDBFDB6C084.taxon	distribution	Distribution and biology. Heterischnus huardi is the most widely distributed North American Heterischnus species. It ranges from the eastern US and throughout Canada to western North America, where it extends north to Alaska, centrally south through the Rocky Mountains, and south along the Pacific Coast through the Sierra Nevada and outer California Coast Ranges. In the California Coast Ranges, it is associated with mixed hardwood forests in the north near Inverness and coastal woodland near Nojoqui Falls Park and Montecito in the south (Kuechler 1978). Bragg (1970) reared five H. huardi specimens from the plume moth, Amblyptilia pica (Walsingham) (Pterophoridae) on Pelargonium (Geraniaceae). Females oviposited into fourth instar prepupae (Bragg 1970). Additionally, two specimens from the CNCI were reared from pterophorids. The first was reared from a Platyptilia pupa collected from Abies (Pinaceae) in British Columbia. The second record was from an unidentified pterophorid pupa collected from Salix (Salicaceae) in Seebe, Alberta.	en	Claridge, Brandon (2021): Revision of Nearctic Heterischnus Wesmael, 1859 (Hymenoptera, Ichneumonidae, Ichneumoninae, Phaeogenini).

Heterischnus mexicanus sp. nov. can be distinguished from all congeners by a combination of the following: 1) flagellomeres 7 / 8 - 11 / 12 dorsally white in female; 2) propodeum densely and coarsely punctate; and 3) longitudinal carinae of propodeum reduced or obsolete with at least lateral longitudinal carina posteriorly obsolete.	en	Claridge, Brandon (2021): Revision of Nearctic Heterischnus Wesmael, 1859 (Hymenoptera, Ichneumonidae, Ichneumoninae, Phaeogenini).

Head black, except following areas white: mandible except for brown apex, venterolateral corners of clypeus, and small ovoid adjacent to eye in supra-antennal area; clypeus varying from black to brownish-red; supraclypeal area brown in one specimen; flagellum brown, flagellomeres 7 / 8 - 11 / 12 with ventral surfaces white. Mesosoma overall brownish-red; anterior margin of pronotal collar, dorsal margin of lateral area of pronotum, subalar prominence, and tegula, white; following areas can be dark brown to fuscous: dorsal 0.5 of propleuron, more or less all of remaining non-white areas of pronotum, dorsal region of mesopleuron immediately below tegula, posterior margin of mesoscutum, metanotum, dorsal division of metapleuron, and propodeum. Fore and middle legs with coxae, trochanters, and trochantelli white except for: basal 0.5 - 0.7 of coxae brownish-red ventrally; femora and tibia brownish-red; tarsomeres light brown to brown. Hind leg brownish-red except for: narrow white apical margin of trochanter; tibia dorsally with irregular light brown maculations; and brown tarsomeres. Metasoma varying from completely brown to dark brown, to having median section of T 1, and lateral margins of remaining tergites, brownish-red and remaining areas dark brown. Wing: membrane clear; basal 0.2 of wing with veins white, remaining vein sections brown. Head.

C5531ABE6EA55DFD9C53BB08541A4A08.taxon	distribution	Distribution and biology. Heterischnus mexicanus sp. nov. is the southernmost ranging Heterischnus species in the New World. Its range spans from the southern border of the USA in Arizona and Texas south to central Mexico in Tehuacan (Fig. 11). Records indicate that adults are active from late July to October and are likely active later in the year in the southern portion of its range as the latter date is from Tehuacan, Mexico. No host records are known for H. mexicanus.	en	Claridge, Brandon (2021): Revision of Nearctic Heterischnus Wesmael, 1859 (Hymenoptera, Ichneumonidae, Ichneumoninae, Phaeogenini).
