A new species and morphometric analysis of Cladonotella (Tetrigidae: Cladonotinae)

Abstract

The genus Cladonotella (Tetrigidae: Cladonotinae) consists of four species of pygmy grasshoppers from Java and New Guinea. A new species of Cladonotella is described from Siargao Island, Philippines: Cladonotella spinulosa sp. nov. This represents the first record of Cladonotella in the Philippines. To quantify differences between species of Cladonotella, we used morphological characters to construct a neighbor-joining tree, and recovered our new species as distinct from congeners. To address the lack of natural history information on Cladonotella, we described habitat and other ecological observations made in Siargao Island on our new species.
