Zimmermann @ Received 14 October 2020 # Accepted 27 November 2020 @ Published 5 January 2021 Abstract The world species of the microgastrine genus Paroplitis (Hymenoptera: Braconidae) are revised. Three new species are described, P. horticola Fuyie & Fernandez-Triana, sp. nov. and P. japonicus Fujie & Fernandez-Triana, sp. nov. from Japan and P. kakhetiensis Fuyie, Japoshvili & Fernandez-Triana, sp. nov. from Georgia. P. vietnamensis van Achterberg & Fernandez-Triana, 2013 1s re-de- scribed, based on additional specimens. P. wesmaeli Ruthe, 1860 is recorded from Georgia for the first time. A key to the nine known species (eight described and one undescribed) of the genus 1s provided. Key Words Palaearctic, taxonomic revision, world key, parasitoid wasps, Japan, Georgia Introduction The subfamily Microgastrinae (Hymenoptera: Braconi- dae) is a large group of parasitoid wasps living on the larvae of Lepidoptera (Mason 1981, Fernandez-Triana et al. 2020). The genus Paroplitis Mason, 1981 is a rather infrequently collected taxon in the subfamily which is poorly represented in collections. This genus was erected to accommodate a group of species in the Microgastrin1 sensu Mason (1981) with strongly flattened mesosoma, short antenna, short and robust legs, smooth metanotum and propodeum usually with a transverse carina. It is dis- tributed in the Nearctic, Palaearctic and Oriental Regions, with five described species previous to this publication (Fernandez-Triana et al. 2013, 2020). As a result of studies being carried out by the authors on the Microgastrinae fauna of Georgia (GJ and JFT), new material, representing one additional species of Paroplitis, was discovered. Additionally, until now, no Species were known in the eastern Palaearctic Region; however, ongoing research on the Microgastrinae fauna of Japan (SF and JFT), has revealed two new species for Japan. This paper describes these three new species and provides an updated key to the world species. Materials and methods Specimens of the new species were collected by Malaise traps and yellow pan traps in Japan and Georgia. The ma- terial has been deposited in the repositories listed below.

Morphological terms and measurements follow Mason (1981), Huber and Sharkey (1993), Whitfield (1997), Karlsson and Ronquist (2012) and Fernandez- dez.pensoft.net Triana et al. (2014). The abbreviations F2, F3, F14 and F15 refer to antennal flagellomeres 2, 3, 14 and 15; Tl, T2 and T3 are used for metasomal mediotergites 1, 2 and 3; and L and W refer to length and width, respectively. Abbreviations for standard measurements of distances between compound eye and ocelli are as follows: POL — Posterior Ocellar Line, OOL — Ocular Ocellar Line, OD — Ocellar Diameter (of a posterior ocellus). For every diagnostic description, we state the number of specimens we measured (using “n = number”), which always included the holotype and some, but not all, paratypes. Dtsch. Entomol. Z. 68 (1) 2021, 33-43 Photos of specimens were taken with Keyence VHX- 1000 and VHX-7000 Digital Microscopes, using a lens with a range of 10-130. Multiple images were taken of the structures through the focal plane and then com- bined to produce a single in-focus image using the soft- ware associated with the Keyence System. Plates were prepared using Microsoft PowerPoint 2010 and saved as . TIF files. A map with the distribution of the species was generat- ed using SimpleMappr (Shorthouse 2010). Results and discussion We recognise eight species of Paroplitis worldwide, in- cluding three new species described in the present paper. 39 We are aware of at least one other undescribed species from India (Ahmed 2017) which we could not examine. It is included in the key, based on the description pro- vided by Ahmed (2017). Although the distributions of some species overlap (Fig. 1), they tend to inhabit dif- ferent altitudes and some species seem to have a limited distribution within a biogeographical region. Paroplitis appears to be mostly distributed in temperate zones, but occasionally reaches northern areas of the Oriental Re- gion (Fernandez-Triana et al. 2013). Including the new taxa described below, three species are recorded from the western Palaearctic, two from the eastern Palaearctic, one from the Nearctic and three from the Oriental Re- gion. We anticipate that additional species will be found as more comprehensive collecting and study of world collections advances.

A detailed description and images of the species in Papp (1991) and Fernandez-Triana et al. (2013). Hosts. Gregarious. Hosts: A gregarious parasitoid of scopariine Crambidae feeding in mosses (Shaw 2012); see also Yu et al. (2016). Distribution. Western Palearctic Region: Azerbaijan, Belgium, Finland, France, Georgia, Germany, Hungary, Poland, Romania, Russia (Krasnodar Kray), Sweden, Switzerland, Ukraine and United Kingdom (Fernan- dez-Triana et al. 2013, 2020). Comments. This species has a widespread distribution in the western Palaearctic Region and it also has relatively large morphological variation — for example, propodeum with a transverse carina (commonly) or without a trans- verse carina (rarely); areola size small (commonly) or rel- atively larger (rarely). We suspect that, under the name P. wesmaeli, there could be a complex of species. However, more collecting and study of specimens (throughout the Palaearctic Region), as well as DNA barcoding, will be needed before any attempt to unravel this complex is made. Paroplitis sp.

This species seems to be closely related to P. rugosus and P. japonicus in having mostly entirely dez.pensoft.net Shunpei Fujie et al.: World review Paroplitis sculptured Tl and T2, comparatively large areolet and R1 almost as long as the length of pterostigma. However, it differs by comparatively slender F15, propodeum with longitudinal carina and comparatively slender metafe- mur, according to photographs by Ahmed (2017: his plate 32). These morphological differences are strong enough to consider it as a Separate species. As we have not been able to examine specimens of this species, it shall remain undescribed for the time being.
