ABSTRACT The genus Labena Cresson is composed of parasitoid wasps that attack wood-boring Coleoptera. In Chile, two species have been recorded, and neither fits into any known Neotropical species-group. We propose two new species-groups: the canelensis group, to include L. canelensis Porter, and the pucon group, to include L. pucon Porter and the newly described L. barrigai sp. nov. In addition, a taxonomic key for all Chilean species is provided.

Abstract A new sand fly species of the genus Trichophoromyia Barretto, 1962, from the state of Amapá, Brazil is described based on both male and female morphology. The new species belongs to the subgenus Trichophoromyia s. str. and the specimens were collected using CDC-type light traps.

ABSTRACT The Phanaeus splendidulus species group comprises five valid species, distributed from the eastern slopes of the Andes through the Brazilian Atlantic Forest to Northeastern Argentina. New distribution records of Phanaeus splendidulus (Fabricius, 1781) have been reported, interpreted by some authors as relictual populations of this species. In this study, we describe a new species of the Phanaeus splendidulus species group, collected in the Northeastern Atlantic Forest and in the Brejos de Altitude of Brazil. The description is based on external morphology of males and females, male genitalia and geographic distribution. We also provide photographic plates of Phanaeus nordestinus sp. nov., a distribution map of the species and a revised identification key for the Phanaeus splendidulus species group.

ABSTRACT Angelabella tecomae Vargas & Parra, 2005, is a leaf-mining micromoth inhabiting xerophytic environments along the western slopes of the Andes in northern Chile and southern Peru, where it is associated with plants of the genus Tecoma Jussieu. Its hypermetamorphic development includes two larval forms: a sap-feeding form during the first four instars, and a spinning form in the final instar. Recent evidence suggests the existence of cryptic diversity within Angelabella Vargas & Parra, 2005 across its geographic range, indicating that the genus may comprise several candidate species that remain unrecognized under current taxonomy. To contribute to the accurate identification of A. tecomae, we provide a detailed redescription of its immature stages based on current standards of descriptive morphology. The sap-feeding and spinning larvae, as well as the pupa, are described in detail using scanning electron microscopy images and illustrated with detailed chaetotaxal maps. In addition, histological sections of leaflets of Tecoma fulva (Cavanilles) D. Don (Bignoniaceae), were examined to characterize the leaf damage produced by the sap-feeding instars and to assess their ontogenetic relationship with changes in mandibular morphology.

ABSTRACT Lopesia rondoniensis Proença & Maia sp.nov., Lopesia tonteleae Proença & Maia sp.nov., and Lopesia matogrossensis Proença & Maia sp.nov., three new species of Cecidomyiidae (Insecta: Diptera) that induce fusiform galls on leaves of Swartzia sp. (Fabaceae), conical galls on leaves of Tontelea sp. (Celastraceae), and lenticular galls on Protium sp. (Burseraceae), respectively, are described and illustrated based on material from Rondônia and Mato Grosso states, Brazil.

ABSTRACT We report three new country records of the genera Hydronema Martynov 1914, Hydropsyche Pictet, 1834, and Macrostemum Kolenati, 1859 in India based on newly collected specimens. Hydropsyche diktynna Malicky and Chantaramongkol, 2000 is reported from Badasgam–B, Jammu and Kashmir; Hydronema persica Martynov, 1914 is reported from Leh, Ladakh (new record of the genus for India) and Macrostemum fenestratumAlbarda, 1887, from Andaman and Nicobar Islands, India. Macrostemum floridum Navás, 1929, a species already known in India, is redescribed based on specimens collected from Andaman and Nicobar Islands, significantly extending the known range of the genus. Two species Macrostemum fenestratum and Macrostemum floridum were subjected to morphological examination and DNA barcoding using the mitochondrial COI gene, because the identification of both species is challenging, due to cryptic morphology. This study presents the first preliminary molecular investigation of Hydropsychidae in India. With these additions, the family Hydropsychidae is now represented in India by 246 species and 16 genera.

ABSTRACT Recent studies have underscored the presence of substantial levels of cryptic diversity among Neotropical species of Drosophilidae. Zygothrica is among the Neotropical Drosophilidae genera whose diversity seems to be severely underestimated. In this study, we describe a new species of Zygothrica, which is externally cryptic and sympatric with Z. vittimaculosa in much of its distribution. To this aim, we compared the sister species and identified differences in the morphology of the phalli and spermathecae that can now be used as diagnostic traits to discriminate between the two species.
