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 spinulosasp. 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.

Highlights

Introduction covered with humps and lappetsSince the genus is currently known only from the islands of Java and New Guinea (Tumbrinck 2014) (Fig. 1), we can expect species to occur on islands between and/or near these two large islands.Recent orthopteran surveys in Siargao Island in the Philippines revealed numerous species new to science and new locality records for other orthopterans (Tan et al 2019a), including Agraeciini katydids and Mogoplistinae, Eneopterinae and Landrevinae crickets

Summary

Introduction

Introduction covered with humps and lappetsSince the genus is currently known only from the islands of Java and New Guinea (Tumbrinck 2014) (Fig. 1), we can expect species to occur on islands between and/or near these two large islands.Recent orthopteran surveys in Siargao Island in the Philippines revealed numerous species new to science and new locality records for other orthopterans (Tan et al 2019a), including Agraeciini katydids and Mogoplistinae, Eneopterinae and Landrevinae crickets (see Tan et al 2018, 2019b–d, Baroga-Barbecho et al 2019). Since the genus is currently known only from the islands of Java and New Guinea (Tumbrinck 2014) (Fig. 1), we can expect species to occur on islands between and/or near these two large islands. This represents the first record of Cladonotella outside Java and New Guinea. This study aims to (1) clarify the taxonomy of Cladonotella with the use of morphometrics, (2) to describe new species of Cladonotella from Siargao Island, and (3) to perform minor cladistic analysis of the genus, by constructing a neighbor-joining (NJ) tree. Tetrigidae, commonly known as the pygmy grasshoppers, is a speciose group of orthopterans typically characterized by a pronotum that extends to cover part or all of the abdomen (Hancock 1907a, Günther 1935, Blackith 1992). This can be attributed to the lack of clear-cut diagnoses
