ABSTRACT
Dolichomitus is a moderately large genus comprising 87 known species, 21 of which occur in the Neotropical region. Here, eight new species from Peru are described and figured: D. chetsorr Inga & Alvarado, sp. nov., D. illa Inga & Alvarado, sp. nov., D. maquinaccasa Inga & Alvarado, sp. nov., D. puka Inga & Alvarado, sp. nov., D. quellue Inga & Alvarado, sp. nov., D. yanasiki Inga & Alvarado, sp. nov., D. urqu Inga & Alvarado, sp. nov., and D. willapi Inga & Alvarado, sp. nov.. Dolichomitus annulicornis (Cameron) and D. meii Di Giovanni & Sääksjärvi are recorded from Peru for first time. Furthermore, Umanella tricoloripes Herrera-Florez is transferred to Dolichomitus, and D. pimmi Araujo & Pádua is synonymized with D. tricoloripes (Herrera-Florez, 2018); and a key to Neotropical species is provided.
ABSTRACT
Apechoneura nigriventris is removed from synonymy and re-instated as a valid species and included in the nigricornis species-group. Apechoneura seminigra is considered a new synonymy of A. nigriventris. Apechoneura pictiventris is included in the carinifrons species-group.

Resumen Se determinó la riqueza y composición de especies de avispas parasitoides nocturnas de la subfamilia Ophioninae en el departamento de Arequipa. Se evaluaron 16 localidades, a lo largo de un gradiente altitudinal que va desde el nivel del mar hasta los 4300 m; en cada localidad se realizaron colectas en los meses de marzo y mayo del 2018. Para la evaluación se emplearon trampas de luz. Se registraron 8 especies y 15 morfoespecies correspondientes a los géneros: Alophophion, Enicospilus, Eremotylus y Ophion. La mayor riqueza de Ophioninae se encontró a 3300 m (S = 8). Los géneros Alophophion y Ophion fueron más abundantes en las localidades sobre los 2000 m, Enicospilus fue más abundante en las localidades que se encontraban por debajo de los 1000 m, y Eremotylus solo se registró en una localidad a los 2300 m.
Abstract The species richness and composition of nocturnal parasitoid wasps Ophioninae subfamily in the Arequipa department was determined. Sixteen localities were evaluated along an altitude gradient that goes from sea level up to 4300 m; in each locality, collections were done in March and May 2018. Light traps were used for the evaluation. A total of 15 morphospecies and 8 species corresponding to the genera: Alophophion, Enicospilus, Eremotylus, and Ophion were registered. The highest richness of Ophioninae was found at 3300 m (S = 8). The genera Alophophion and Ophion were more abundant at medium to high elevations, Enicospilus was more abundant at low altitude localities, and Eremotylus was only recorded in a medium altitude locality.
ABSTRACT
The genus Eremotylus Forster currently comprises 16 described species, two of them occurring in the Neotropical region. The genus is recorded for the first time in Peru and Eremotylus pukayana sp. nov. is described. A key for the Neotropical species is also presented.

Mnioes Townes is a predominantly Neotropical genus of the family Ichneumonidae, mainly documented from Central America and, until now, with no described species from South America. In this paper, ten new species are described from Peru: Mnioes attenboroughi sp. nov., M. huk sp. nov., M. iskay sp. nov., M. kinsa sp. nov., M. pisqa sp. nov., M. poncei sp. nov., M. pusaq sp. nov., M. qanchis sp. nov., M. soqta sp. nov., and M. tawa sp. nov. A key to the Peruvian species and maps of their geographical distribution are also presented.

We describe and figure a distinctive new species of the bee genus Andinopanurgus Gonzalez and Engel (Andrenidae, Protandrenini) from Apurímac and Cusco in southern Peru. Andinopanurgus vargasllosai Gonzalez and Alvarado, n. sp., occurs at elevations above 4000 m in the Central Andes and is the second species of this genus in Peru. The new species possesses terga with semi-translucent distal margins, a unique feature among Andinopanurgus, and it combines morphological features of the two species groups previously recognized in the genus. To facilitate its recognition, we provide an updated key to species of Andinopanurgus.
Describimos e ilustramos una especie nueva del género Andinopanurgus Gonzalez y Engel (Andrenidae, Protandrenini) procedentes de Apurímac y Cusco, al sur de Perú. Andinopanurgus vargasllosai Gonzalez y Alvarado, n. sp., se encuentra en alturas superiores a los 4000 m en los Andes centrales y es la segunda especie del género registrada para el Perú. La especie nueva posee tergos metasomales con las márgenes distales semi-translúcidas, una característica única dentro de Andinopanurgus, y combina características morfológicas de los dos grupos de especies hasta ahora reconocidos en el género. Con el fin de facilitar la identificación, presentamos una clave actualizada para las especies de Andinopanurgus.
ABSTRACT
A fossil palpigrade is described and figured from mid-Cretaceous (Cenomanian) amber from northern Myanmar. Electrokoenenia yaksha Engel and Huang, gen. n. et sp. n., is the first Mesozoic fossil of its order and the only one known as an inclusion in amber, the only other fossil being a series of individuals encased in Pliocene onyx marble and 94-97 million years younger than E. yaksha. The genus is distinguished from other members of the order but is remarkably consistent in observable morphological details when compared to extant relatives, likely reflecting a consistent microhabitat and biological preferences over the last 100 million years.

The ichneumonid genus Habronyx is recorded for the first time from Peru and Ecuador, and three new species are described and figured-Habronyx (Camposcopus) flavus Alvarado, new species, H. (Habronyx) nigrofasciata Alvarado, new species, and H. (H.) saqsaywaman Alvarado, new species. Hadronyx (H.) punensis is recorded for the first time in Peru. Habronyx (H.) nigrofasciata was reared from Paracles tapina (Dyar, 1913) (Erebidae: Arctiinae). In addition, the distribution of P. tapina is expanded and figures of its larvae, pupae, and adult female and male are provided.
