The second paper from the current issue of the Journal of the International Heteropterists’ Society:

Hisasue Y. & Souma J.: "First Report on the Seasonal Occurrence of True Bugs (Hemiptera: Heteroptera) Endemic to Oceanic Islands: Case Studies on Chichijima Island, the Ogasawara Archipelago, Japan"

The seasonal occurrence of adults and nymphs of endemic heteropteran species, including semi-aquatic predators, terrestrial herbivores, and predators on the subtropical island of Chichijima, the Ogasawara Archipelago, Japan, is described. Year-round occurrence was observed for Xiphovelia boninensis Esaki and Miyamoto (Veliidae), Microvelia yoshitomii Watanabe (Veliidae), Micracanthia boninana (Drake) (Saldidae), Omoplax desecta (Horváth) (Tingidae), Kitocoris omura Herring (Anthocoridae), and an undescribed species in the genus Pachygrontha Germar (Pachygronthidae), suggesting prolonged reproductive periods and multivoltinism. In contrast, nymphs and adults of Lygocorias boninensis (Yasunaga) exhibited a distinct seasonal absence. Data for Gardena boninensis Ishikawa and Nesoproxius kishimotoi Shimamoto and Nagashima were not adequate to determine any seasonal pattern. Species seasonal occurrence patterns differed between habitats and are possibly associated with habitat suitability, wing morph frequency, and host plant phenology. This study is the first to compare the year-round seasonal occurrence of adults and nymphs among multiple endemic heteropteran families on an oceanic island and provides the first information on the seasonal occurrence and voltinism for the family Pachygronthidae.

Dear fellow heteropterists,

We are pleased to announce that the fourth issue in the third volume of our quarterly Journal of the International Heteropterists’ Society (JIHS) is now available!

The first published paper:

Sites R.W. & Suputa: "A New Species of the Saucer Bug Genus Idiocarus Montandon, 1897 (Hemiptera: Heteroptera: Naucoridae) from Mountain Streams in West Papua, Indonesian New Guinea"

The saucer bug genus Idiocarus (Naucoridae: Naucorinae: Tanycricini) is endemic to the island of New Guinea and is represented by six species. Diagnostic features by which to identify species include conditions of the profemur, male left paramere, and female subgenital plate. Herein is described Idiocarus clypealis n. sp., which can be recognized by an elongated anteclypeus, tuberculate profemur, shape of the male left paramere, slender golden bristles on the female subgenital plate, and overall body length. The new species is known from eight mountain streams in the Vogelkop Peninsula of West Papua Province, Indonesian New Guinea.

New paper!

Leiva-Espinoza S.T. et al.: "First report of Monalonion velezangeli (Hemiptera: Miridae) damaging avocado (Persea americana) in Peru".

Avocado (Persea americana Mill.) is an economically important fruit crop whose expansion has been accompanied by the emergence of new insect pests affecting yield and fruit quality. During field surveys conducted in avocado plantations in the Amazonas region of northern Peru, severe damage associated with a mirid bug was observed on young fruits and vegetative shoots. This study aimed to identify the causal insect and characterize the associated damage through morphological and molecular analyses. Adult and nymph specimens were collected from five plantations and identified using diagnostic morphological traits and taxonomic keys. Molecular confirmation was performed using mitochondrial cytochrome c oxidase subunit I (COI) sequences and phylogenetic analysis based on the Maximum Likelihood method. Both morphological and molecular evidence confirmed the species as Monalonion velezangeli. Field observations showed that the insect primarily attacks young fruits and shoots, causing necrotic lesions and punctures that reduce fruit commercial quality. This study represents the first confirmed report of M. velezangeli affecting avocado in Peru.
