Review of the plant bug genus Fingulus Distant in Indochina (Hemiptera: Heteroptera: Miridae: Deraeocorini), with descriptions of two new species

Abstract

The deraeocorine plant bug genus Fingulus Distant from Indochina is reviewed, diagnosed and discussed. Seven species are currently recognized, including two new species described herein: F. angkorensis and F. rubricatus from Cambodia and Thailand. Behavior and habitat of F. angkorensis are documented, which was observed to be associated with two anthocorids and a thrips in leaf margin curl-galls produced by the thrips on a banyan tree Ficus microcarpa. A checklist including two species of the assumed sister genus Angerianus Distant is provided, with available distributional records; images of two Angerianus species are also shown for the first time.

Two new deraeocorine plant bug species from Japan (Heteroptera, Miridae, Deraeocorinae)

“…The present paper documents two new species of the Deraeocorinae, Fingulushenrytomi (tribe Deraeocorini) and Stethoconustakaii (Hyaliodini), which were found in the temperate climate zones of southeastern Japan. Although the majority of the members of Fingulus Distant and Stethoconus Flor are thermophilic and known predominantly from the tropics and subtropics (Nakatani et al 2000, Nakatani and Yasunaga 2001, Schuh 1995, 2002–2014, Stonedahl and Cassis 1991, Yasunaga et al 1997, 2016), the new species extend the range of these genera farther north than expected. The new species are also considered predacious, as species belonging to Fingulus and Stethoconus in other regions are well known as predators (e.g., Henry et al 1986; Neal et al 1991; Wheeler 2001; Yasunaga et al 1997, 2016).…”

Color habitus images of live individuals and scanning electron micrographs are presented for the two new species and their closely related congeners.…”
