Introduction
The genus Leptoglossus Guérin-Méneville, 1831 consists of 62 species and is one of
the most diverse and complex taxa of the tribe Anisoscelini within the Coreidae in the
western hemisphere. It is cosmopolitan, mainly widely distributed in the Nearctic and in
the Neotropical region (Brailovsky and Barrera 2004; Brailovsky 2014; van der Heyden and
Gamboa Hidalgo 2014; Faúndez and Carvajal 2016; CoreoideaSF Team 2019). The genus
Leptoglossus in Guatemala is commented. First and new records of species within the genus
Leptoglossus from Guatemala are reported. A revised key to the known species of the genus
from Guatemala is provided.

... Collected insects were first identified to the family level using identification keys adapted to insects from tropical zones [12,[40][41][42][43][44][45][46][47]. Specimens were identified to the species level by referring to descriptions and figures available in appropriate keys for Coleoptera [47,[48][49][50][51][52][53][54][55], key for Diptera [56], keys for Hemiptera [43,[57][58][59], keys for Lepidoptera [45,46,60,61], keys for Coreidae [62] and keys for Orthoptera [63][64][65][66]. Identification of species was confirmed by referring to illustrated catalogs and check lists [44,55]. ...

Some of the known leaf-footed bugs of the family Coreidae are being considered as invasive species. The authors collected and identified adults of seven species on orange var. Valencia, in the town of Cuauchichinola, Mazatepec, Morelos. Of these three species Leptoglossus zonatus had greater relevance in the collections, followed by two species (Narnia sp y, Leptoglossus concolor). To date, there were no records of incidence of these bugs on the citrus zone in Morelos state, specifically on orange var. Valencia, so it must be monitored and valued as potentially dangerous pests associated with damage and fruit drop in the citrus areas of the state, as well as their possible economic impact

The invasive alien leaf‐footed bug Leptoglossus gonagra (Fabricius 1775), native to the Americas, is herein recorded from South Korea for the first time. Forty nymphs and adults were collected on 22 September 2016 from arable lands of two separate sites. These individuals were identified based on the analysis of morphological characters and cytochrome oxidase c subunit 1 sequences. A neighbor‐joining tree indicated the existence of two clades: Group A from Brazil, and Group B from Asia and Oceania. Mean genetic distance between clades was 8.11%, range 7.60–8.57%. Within clades, mean genetic distance was 0.42% (0.17–0.83%) in Group A and, 0.45% (0.00–0.83%) in Group B. Colonies of 2nd‐final instar nymphs and adults were found, on top of leaves, flowers, fruits, and between the stems of pumpkins (Cucurbita moschata). Nymphs and adults damaged host plants by sucking their leaves, stems, fruits, and buds. After the first discovery in 2016, we were unable to find the bugs again (in 2017–2019). Therefore, the invasion of this species seems to have occurred only temporarily, during the warm season. We suggest that the species may have failed to overwinter as it is normally distributed in regions warmer than Korea. Nevertheless, possible appearances of this species must be continuously monitored as it is a potential pest of various plants cultivated in South Korea.

Background Coreidae bugs are mostly sap-sucking insects feeding on a variety of plants. Despite their abundance and economic importance in Honduras there is little information on the species, their distribution and affected crops. Since knowledge of pest species allows for better management of crops, we aimed to document the diversity of this economically important group. Specimens from four entomological collections in Honduras were studied and an exhaustive search of all available literature was conducted. New information A total of 2,036 insects were examined. The fauna of Honduran coreids is now composed of 68 species. Nineteen species are recorded for the country for the first time and 17 species were found only in literature. Little is known about the biology and economic importance of most of the species.

The relationship between Leptoglossus chilensis and L. concaviusculus is studied. It is concluded that L. concaviusculus deserves full species rank. Figures of both species are included with emphasis on male genitalia. The V nymph of L. concaviusculus is described.
