First record of Telenomus fariai Costa Lima, 1927 (Hymenoptera, Scelionidae, Telenominae) as a parasitoid of Triatoma dimidiata (Latreille, 1811) (Hemiptera, Reduviidae, Triatominae) eggs in Mexico

The egg parasitoid Telenomus fariai Costa Lima (Hymenoptera, Scelionidae), is reported for the first time in Veracruz, Mexico. Telenomus fariai was discovered in 2019 during a field collection of Triatoma dimidiata L. (Hemiptera, Reduviidae), representing the first report of its association with Tr. dimidiata in Mexico. This species is here redescribed and sequencing of a portion of the cytochrome oxidase 1 gene (COI) was performed to facilitate future identifications and to examine host associations between species of Telenomus Haliday and Reduviidae in a broader context.

The Pyrenean species of Chelidura (Dermaptera, Forficulidae)

The Pyrenees are inhabited by scattered populations of earwigs of the genus Chelidura Latreille, 1825. There is some controversy about the specific assignment of these populations: while most authors assign them to C. pyrenaica (Gené, 1832), other consider that C. aptera (Mégerlé, 1825) is also present in the Pyrenees. The main objective of this work was to revise the identity and synonyms of Pyrenean Chelidura. Specimens from recent fieldwork and collections (MNCN-CSIC) were used for morphological and molecular studies (cytochrome oxidase 1). All Pyrenean specimens shared similar cox1 sequences, very divergent from those of Alpine C. aptera. As a consequence, the variability observed in male cerci morphology from the Pyrenees, ranging from long and slightly curved to short and very curved, corresponded to C. pyrenaica, and the presence of C. aptera in the Pyrenees can be rejected. As previously suggested by Maccagno (1933) and Fontana et al. (2021), the revision of the synonymic list uncovered the misplacement of the name F. simplex Germar, 1825 under the synonymy of C. aptera, while it rather represents a synonym of C. pyrenaica (syn. nov.). Forficula simplex has nomenclatural priority over C. pyrenaica, however both names meet the requirements of the article 23.9.1 of the International Code of Zoological Nomenclature to retain the prevailing usage of C. pyrenaica (nomen protectum) over F. simplex (nomen oblitum). Additionally, we discuss the taxonomic status of Chelidura arverna David & Van Herrewege, 1973 stat. nov. from the French Massif Central.

Parasitoids of Chrysopidae Eggs in Sinaloa Mexico

The eggs parasitoids Myartsevaia chrysopae (Crawford) (Hymenoptera: Encyrtidae), Telenomus lobatus Johnson, Telenomus tridentatus Johnson (Hymenoptera: Scelionidae) and Trichogramma atopovirilia Oatman and Platner (Hymenoptera: Trichogrammatidae) are reported for the first time or in new localities in Mexico. Their occurrence was first discovered in 2018 during a survey of parasitism on chrysopid eggs, conducted on Sorghum bicolor L. Moench (Poales: Poaceae) and Zea mays L. (Poales: Poaceae) in different locations in Sinaloa, Mexico. The identity of the parasitoids was determined by morphology and for both species of Telenomus the barcode region of the cytochrome oxidase 1 gene (CO1) was generated to facilitate molecular diagnosis of these species in future studies.

Notes on the distribution and habitat of Ochthebius lobicollis Rey, 1885, a poorly known north-western Mediterranean coastal species (Coleoptera: Hydraenidae)

Ochthebius (Ochthebius) lobiccoastal habitatsollis Rey, 1885 is recorded for the first time from the Iberian Peninsula (Girona) and the island of Corsica; new records are also given for the islands of Menorca and Sardinia. The species is known only from coastal habitats through the Gulf of Lion and the Ligurian and Balearic seas, typically living in rockpools of different salinity or small trickles or freshwater runoffs. Genetic data of the cytochrome oxidase 1 gene from Iberian, Menorcan and Sardinian specimens shows less than 1% divergence, suggesting lack of isolation between populations.
