A new species of Saccharosydne Kirkaldy from Argentina (Hemiptera: Delphacidae)

Saccharosydne is the most diverse genus of the tribe Saccharosydnini. Male, female and nymphal Saccharosydne have been captured in recent collections from garlic (Allium sativum), rye (Secale cereale) and pampas grass (Cortaderia spp.) in Argentina. In this contribution, we describe and illustrate a...

Description
Summary:Saccharosydne is the most diverse genus of the tribe Saccharosydnini. Male, female and nymphal Saccharosydne have been captured in recent collections from garlic (Allium sativum), rye (Secale cereale) and pampas grass (Cortaderia spp.) in Argentina. In this contribution, we describe and illustrate a new species S. subandina sp. nov., adding information on the geographical distribution and host plants. Saccharosydne subandina can be distinguished from its congeners by the following combination of features: uniformly light green-yellowish color with a distinctive rounded black macula on both genae; vertex 1.5x longer than wide, and projecting beyond eyes almost one half of its length; parameres divergent with internal and external angles acute; and dorsolateral angles of pygofer produced caudad. A key for species identification based on male genitalia and external morphology, is provided.
