Issini
Issini is a tribe of small planthoppers within the family Issidae, characterized by stocky, usually brownish bodies measuring 5–20 mm. Members possess hemispherical body shapes and often exhibit reduced flight capability despite having developed wings, preferring crawling and jumping in vegetation. The tribe is distributed across the Oriental realm, with significant diversity in southern China. Issini includes four subtribes: Hemisphaeriini, Parahiraciini, Issini, and Colpopterini.
Trogloneta
spurred orb-weavers
Trogloneta is a genus of minute spurred orb-weavers in the family Mysmenidae, described by Eugène Louis Simon in 1922. The genus currently comprises twelve described species distributed across Europe, East Asia, and the Americas. These spiders are among the smallest known spiders, with some species measuring less than 2 mm in body length. Several species exhibit cave-adapted characteristics and restricted distributions, with some Chinese species showing extreme population genetic divergence due to geographic isolation in karst cave systems.
