Materials & Methods
Specimens were examined from the Canadian National Collection of Insects, Arachnids and Nematodes (CNC, Ottawa, Canada), Michigan State University: A.J. Cook Arthropod Research Collection (MSUC, E. Lansing, Michigan, USA), and the collection of Miloš Kníek, Prague, Czech Republic. Specimens used to generate the key were previously identified by A. Cognato, D. Bright, and M. Kníek. Twenty to 100 specimens per species were examined for all species except for the following, for which only 1 to 10 specimens were available: I. chinensis, I. hauseri, I. longifolia, I. pilifrons thatcheri, I. schmutzenhoferi, I. shangrila, I. stebbingi, I. subelongatus. Sarah Smith and the USA National Museum of Natural History, Smithsonian Institution, Washington, D.C. provided images of the holotype of I. pilifrons thatcheri. Specimens were photographed using a Leica M205c stereoscope and multifocus images assembled using Leica LAS 4.8 software. Pale specimens were favoured for photography to increase visual contrast of spines and punctures against background integument. The key and species descriptions were built using LUCID 3.6 software. Primary type specimens were not examined, so morphological summaries in associated fact sheets should be considered as diagnostic tools only.
