Abstract
Two new records of the Deraeocorinae (Hemiptera: Heteroptera: Miridae) are reported from the Korean Peninsula, Termatophylum hikosanum Miyamoto, 1965 and Fingulus longicornis Miyamoto 1965. With these species, their higher taxa, the tribe Termatophylini and the genus Fingulus are also reported for the first time to the Korean fauna. Morphological and biological information of the species are provided with photographs.
Introduction

Keywords: Miridae, Deraeocorinae, Termatophylini, Fingulus, new record, the Korean Peninsula
The subfamily Deraeocorinae (Hemiptera: Heteroptera: Miridae) have a world-wide distribution and
EP
comprise six tribes up to date: Clivinemini, Deraeocorini, Hyaliodini, Saturniomirini, Surinamellini and Termatophylini (Wheeler 2000; Schuh 2002–2013). These deraeocorine plant bugs are predominantly known as general predators, and some groups (e.g. Clivinematini and Hyaliodini) and/or some species (e.g. Stethoconus
AC C
japonicus and Fingulus longicornis ) are reported as specialized predators for specific insect pests such as lace bugs, thrips and scale insects (Wheeler 2000, 2001). Therefore, deraeocorines are considered important economically on agriculture, forest or ecosystems (Wheeler 2000). In this study, two deraeocorine species, Termatophylum hikosanum Miyamoto, 1965 and Fingulus longicornis Miyamoto, 1965, are recorded from the Korean Peninsula. Based on discoveries of these species, their higher taxa, the tribe Termatophylini and the genera Termatophylum and Fingulus of the subfamily Deraeocorinae are also recorded for the first time from the Korean fauna. The tribe Termatophylini is distributed in all zoogeographical regions, apart from the Nearctic region, and comprises 10 genera and 34 species in the world (Cassis 1995; Cassis and Eyles 2006; Cassis et al 2011). Most members of this group are recognized by anthocorid-like habitus and head form, and are reported as predators for minute arthropods in microhabitats such as bark of woods (Cassis 1995; Schuh and Slater 1995; Nakatani 1997).
ACCEPTED MANUSCRIPT The genus Fingulus Distant, one of the Deraeocorini genera, is easily recognized from other deraeocorines by unique structures: head projected dorsally; neck-like posterior part of head; collar distinctly broad and flattened; cuneal fracture well developed; and unique male genitalia (Stonedahl and Cassis 1991). In addition, in case of the last instar of this group, elongated abdominal segment, one of the unique characters, apparently exhibits thrips-mimicry, which is related with their prey as a thrip predator (Nakatani et al 2000).

Material and methods
Photographs of dorsal habitus of each specimen were taken by Leica M165C microscope. Measurements were taken using a software program of the same microscope. All measurements are given in millimeters (mm). Terminology mainly follows Nakatani (1997). Depository of the type specimen is Entomological Laboratory, Faculty of Agriculture, Kyushu University (ELKU), Fukuoka, Japan. Depository of the examined specimens is
