Zemacrosaldula, a new genus of Saldidae (Hemiptera: Heteroptera) from New Zealand: taxonomy, geographic distribution, and biology

Abstract

Zemacrosaldula, new genus, is described with Salda australis White, 1876, as type species, resulting in the following new combination Zemacrosaldula australis (White, 1876). Three new species are described: Zemacrosaldula kapekape new species, Z. whakarunga new species, Z. pangare new species. A revision of the taxonomy of all taxa is presented. Species are keyed. Morphological descriptions are provided together with illustrations emphasising the most significant diagnostic features of external morphology and male genitalia. Information is given on synonymy, type specimens, material examined, geographic distribution and biology.

Aoteasalda and Kiwisaldula, two new genera of Saldidae (Hemiptera: Heteroptera), with a key to New Zealand genera and a new synonymy in Zemacrosaldula

“…Environmental factors also seem to be at play, cooler temperatures and/or higher humidity generally shifting the eunomic series towards the dark side of the sequence while the reverse produces lighter forms. These trends were also noted and briefly discussed by Larivière & Larochelle (2015) for species of the genus Zemacrosaldula. All species and most populations of Kiwisaldula will harbour a few very dark individuals with reduced hemelytral markings and very narrowly pale to almost completely dark lateral margins of pronotum.…”

“…The genus Zemacrosaldula was erected by Larivière & Larochelle (2015) to accommodate Saldula australis (White, 1876) and three new species. A key to Zemacrosaldula species was provided as well as detailed information on geographic distribution and biology.…”

Kiwisaldula waiho and K. hurunui, two new species of Saldidae (Hemiptera: Heteroptera) from the South Island of New Zealand, with redescriptions of K. butleri (White) and K. laelaps (White)

“…Terms particular to Saldidae morphology, including the terminology used to describe the degree of wing development, mostly follow Schuh & Polhemus (2009) except as noted by Larivière & Larochelle (2015.…”

“…The male genitalia of representatives of as many populations as possible were dissected and examined in the manner described by Larivière & Larochelle (2015).…”

“…Larivière & Larochelle (2015) erected the genus Zemacrosaldula which occurs on both main islands of New Zealand and contains four species. Subsequently, these workers (Larivière & Larochelle 2016) studied the North Island and nearby offshore islands saldids, and the type series of two South Island species.…”
