ABSTRACT

The Neotropical genus Phylloicus Müller, 1880 has 62 species distributed mainly in Latin America, 27 of which are recorded in Brazil. Larvae of the genus are shredders of organic matter, playing an important role in leaf decomposition in Neotropical streams. They are used in biological and ecological studies. However, only 26% of Phylloicus species have their immature stages described. In order to increase taxonomic knowledge of this genus, we describe and illustrate the larva and pupa of Phylloicus elektoros Prather, 2003. Association of adults of this species with their immature stages was performed through rearing larvae and pupae under laboratory conditions and using the metamorphotype method. The case of P. elektoros has 10–13 leaf fragments. Larvae can be recognized by the reddish-brown color of the head and the hastate-shaped submentum of the genae ventrally. Pupae have almost all of their hook plates with 3–4 pointed, stout hooks.

亚马逊碎石蝇 Phylloicus elektoros Prather,2003(毛翅目:Calamoceratidae):幼虫和蛹的描述

摘要

新热带Phylloicus Müller属,1880有62种,主要分布在拉丁美洲,其中27种记录在巴西。该属的幼虫是有机物的粉碎者,在新热带溪流中的树叶分解中发挥着重要作用。它们用于生物学和生态研究。然而,只有 26% 的Phylloicus物种有其未成熟阶段的描述。为了增加该属的分类学知识,我们描述并说明了Phylloicus elektoros Prather, 2003 的幼虫和蛹。该物种的成虫与其未成熟阶段的关联是通过在实验室条件下饲养幼虫和蛹并使用变态方法来进行的。P. elektoros的案例有 10-13 个叶碎片。幼虫可以通过头部的红棕色和腹侧的齿状下基部来识别。蛹几乎所有的钩板都有 3-4 个尖的、粗壮的钩。
