RESUMEN

Mexican species of three pimpline genera, Neotheronia Krieger (24 species), Nomosphecia Gupta (two species) and Xanthopimpla Saussure (one species) are reviewed. Five species of Neotheronia are described as new to science: N. altacima sp. nov., N. bonita sp. nov., N. juanitae sp. nov., N. tequila sp. nov. and N. zaldivari sp. nov. Neotheronia septemtrionalis Krieger, 1905 is found to be a junior synonym of N. nigrolineata (Brullé, 1846) (syn. nov.). Seven species of Neotheronia are new records from Mexico: N. bostrandae Gauld, N. charli Gauld, N. donovani Gauld, N. hespenheidei Gauld, N. lizzae Gauld, N. lloydi Gauld and N. matamorosi (Brullé). Moreover, Neotheronia concolor Krieger, N. lineata (Fabricius), N. mellosa (Cresson) and N. nigrolineata (Brullé) are recorded for the first time from Honduras, and N. rosai Gauld is recorder for the first time from Guatemala. South American species Neotheronia cristata Krieger is excluded from the Mexican fauna. Identification keys to species of Neotheronia and Nomosphecia occurring in Mexico are provided.

RESUMEN

Five new species of Tersilochinae (Ichneumonidae) are described from Mexico: Meggoleus hidalgoensis sp. nov., M. whartoni Khalaim, sp. nov., Phradis belovi Khalaim, sp. nov., Stethantyx covida sp. nov., and St. oaxacana sp. nov. Meggoleus whartoni Khalaim, sp. nov. is also recorded from Panama, and St. covida sp. nov. from Guatemala. The species recently described from Mexico Probles contrerasi Khalaim & Ruíz-Cancino is transferred to the genus Gelanes Horstmann, comb. nov. A partial key to the species of Meggoleus with small propodeal spiracles and a key to Mexican species of Phradis are provided.

ResumenSe describen cinco especies nuevas de Tersilochinae (Ichneumonidae) para México: Meggoleus hidalgoensis sp. nov., M. whartoni Khalaim, sp. nov., Phradis belovi Khalaim, sp. nov., Stethantyx covida sp. nov. y St. oaxacana sp. nov. Meggoleus whartoni Khalaim, sp. nov. se registra también para Panamá y St. covida sp. nov. para Guatemala. Probles contrerasi, una especie recientemente descrita para México, se transfiere al género Gelanes Horstmann, comb. nov. Se elaboró una clave parcial de las especies de Meggoleus con espiráculos propodeales pequeños y una clave para las especies mexicanas de Phradis.

RESUMEN

We present a synthesis of the insects reported associated with plants of the genus Agave L. (Asparagaceae) in Mexico, through a detailed review of published records. This work includes two checklists: the first include the species of insects collected in Agave, name of their hosts, their geographical distribution, notes on their biology and, references. Natural enemies of the insects associated with agaves are included in the second checklist with their geographical distribution, insect species host and, references. We found 273 species of insects collected in different Agave species. These species belong to 63 families and 7 orders. The orders of insects with the highest number of species are Coleoptera with 118 species and, Hemiptera with 65. The natural enemies of insects collected in agaves were 98 species from 18 families and 6 orders. The genera Aphytis and Encarsia (Hymenoptera: Aphelinidae) grouped the largest number of natural enemies of insects that were recorded in Agave with 15 and 10 species, respectively. Insects were collected from 42 species of Agave, of which 25 are endemic to Mexico. This study provides biological information on Mexican insects captured in Agave and, their natural enemies. The need for the conservation of these plants and associated insects is highlighted.

RESUMEN

Two new species of the tryphonine genus Exenterus from Mexico, E. durangensis Khalaim & Ruíz-Cancino, sp. nov. and E. sehuerachicus Khalaim & Ruíz-Cancino, sp. nov., are described. Both species belong to the group of Exenterus species characterized by the unusually short, depressed tarsi. Exenterus durangensis was reared from the sawfly Zadiprion falsus Smith and E. sehuerachicus from Neodiprion autumnalis Smith (Hymenoptera: Diprionidae). This is the first record of the genus Exenterus as a parasitoid of these hosts. An identification key to separate the two Mexican species of Exenterus is provided.

RESUMEN

A new genus of Metopiinae, Ojuelos Khalaim, gen. n., with a single species, Ojuelos juachicus Khalaim & Ruíz-Cancino, sp. n., is described from Jalisco Province in central Mexico. Ojuelos belongs to the group of three genera (Cubus Townes & Townes, Colpotrochia Holmgren and Triclistus Förster) having a high lamella separating the antennal sockets and reaching the median ocellus (this lamella possesses a dorsal groove in it, just below the median ocellus), but differs from these genera primarily by 1) face and clypeus not convex in lateral view, 2) face separated from clypeus by a shallow transverse impression, 3) mandible with lower tooth very strongly reduced, 4) flagellomeres of antenna strongly transverse, and 5) dorsal carinae of propodeum reduced. A portion of the key to the genera of Metopiinae is provided to distinguish the new genus.
