Abstract

Clinodiplosis cecropiae Proença & Maia a new species of Cecidomyiidae (Insecta: Diptera) is described and illustrated herein (larva, pupal exuviae, male and female). Samples of gall and host plant were collected in Amazon Rainforest areas, in Monte Negro municipality, Rondônia state, Brazil. The galler was obtained by rearing in laboratory. The specimens were mounted on microscope slides. The type material is deposited in the Cecidomyiidae collection of Museu Nacional/Universidade Federal do Rio de Janeiro. The new species induces globoid galls on stems of Cecropia sp. (Urticaceae). This is the first record of a Clinodiplosis species inducing galls on Urticaceae plants.

Highlights

Clinodiplosis Kieffer, 1894 (Cecidomyiidi: Clinodiplosini) is a cosmopolitan genus, with 107 species described so far, most part being mycophagous, but some with phytophagous and galling inducer habits

In the Neotropical region most Clinodiplosis species are responsible for complex galls

Summary

Introduction

Clinodiplosis Kieffer, 1894 (Cecidomyiidi: Clinodiplosini) is a cosmopolitan genus, with 107 species described so far, most part being mycophagous, but some with phytophagous and galling inducer habits. In Brazil, there are 17 described species, the majority being gallers, mostly attacking the leaves of Amaranthacea, Asteraceae, Erythroxylaceae, Euphorbiaceae, Lamiaceae, Malpighiaceae, Melastomataceae, Moraceae, Myrtaceae, Rubiaceae, Sapindaceae and Verbenaceae (Gagné & Jaschhof, 2017; Toma & Maia, 2012). The new species described here induces galls (Fig. 1) on leaves petioles of an unidentified species of Cecropia Loefl. In Brazil, this plant is commonly known as “embaúba” and can be found in all phytogeographical domains: Amazon rainforest, Caatinga (dry forest), Cerrado, Atlantic forest and Pantanal, except Pampa (Flora do Brasil, 2019)
