Item Description of immature forms of two Diadiplosis species (Diptera: Cecidomyiidae) from the Neotropical Region with additional notes about adult morphology(Sociedade Brasileira De Entomologia, 2025-04-11) Ospina-Peñuela, Esau; Balbi, Maria Isabel Protti de Andrade; Urso-Guimarães, Maria VirginiaDiadiplosis is a genus of predatory midges for which the immature stages of most species lack detailed morphological information or remain undescribed. Diadiplosis coccidarum (Cockerell, 1892) and Diadiplosis coccidivora (Felt, 1911) are midges that prey on nymphs of several mealybugs and have been described based on male and female specimens. We describe and illustrate for the first time the third instar larva and pupa of D. coccidarum, collected preying on nymphs of Saccharicoccus sacchari (Hemiptera: Pseudococcidae) on Saccharum officinarum (Poaceae) in an agroecosystem from Colombia, and the pupa of D. coccidivora, collected preying on specimens of Coccus brasiliensis (Hemiptera: Coccidae) on fruits of Coffea canephora (Rubiaceae) in Brazil. In this study, we also provide new morphological data on the adults of D. coccidarum and D. coccidivora.Item The coffee leaf miner, Leucoptera coffeella (Lepidoptera: Lyonetiidae): identification of the larval instars and description of male and female genitalia(Sociedade Brasileira De Entomologia, 2021) Motta, Isabela O.; Dantas, Juliana; Vidal, Leonardo; Bílio, JoãoThe coffee leaf miner Leucoptera coffeella (Guérin-Mèneville & Perrottet) is a key pest in coffee producing countries. During their development, the larvae feed on the palisade parenchyma of the leaves, forming mines and necrotic areas. As a result, the photosynthetic area of the plant decreases, affecting coffee production. Despite the severity of the damage caused by coffee leaf miner (CLM), morphological aspects of the larval development and the adult genitalia remain unknown. This work presents the first morphological description of the four larval instars and the adult genitalia of L. coffeella. In each larval instar, we measured the Mean ± SD (mm) of the cephalic capsules (1st 0,14±0,03; 2nd 0,25±0,04; 3rd 0,32±0,03; 4th 0,42±0,03) and observed the following morphological details: primary setae, prolegs, crochets and ecdysial line of the cephalic capsule. In the adults, we show how to differentiate adult sexing and observed the sexual structures present in both genitalia: male - bulbus ejaculatorius, valva, gnathos and aedeagus, and female - ovipositor, sclerite and corpus bursae.
