World revision of Xenomerus Walker (Hymenoptera: Platygastroidea, Platygastridae)

Abstract

The Old World genus Xenomerus Walker is revised. Thirty one (31) species are recognized based on 879 specimens. Twenty four (24) new species are described: X. armatus (Oriental), X. aureipes (Ethiopian), X. bickeli (Australian), X. comatus (Ethiopian), X. fulleri (Australian), X. gloriosus (Australian), X. guinensis (Australian), X. halteratus (Australian), X. hilleri (Australian), X. feehani (Ethiopian), X. kalocsai (Ethiopian), X. malawi (Ethiopian), X. melikai (Australian), X. melleus (Australian), X. noyesi (Oriental), X. ochraceus (Ethiopian, Oriental), X. orientalis (Oriental), X. parorientalis (Oriental), X. rugifrons (Oriental), X. scutellatus (Ethiopian), X. spinosus (Oriental), X. vanharteni (Ethiopian), X. watshami (Ethiopian) and X. yamagishii (Oriental, Palaearctic). Redescriptions and new combinations for the following species are provided: Xenomerus buccatus (Kononova & Kozlov) from Trimorus; Xenomerus calligetus (Kononova & Kozlov) from Trimorus; X. cornutus (Kononova & Kozlov) from Trimorus. Xenomerus canariensis Huggert, X. ergenna Walker, X. laticeps Dodd and X. varipes Dodd are redescribed. New synonymies are proposed: Trimorus mutator Kononova & Kozlov = X. canariensis Huggert, Trimorus curtum Kononova & Kozlov = X. ergenna Walker, Xenomerus hibernicus Mineo & O’Connor = X. canariensis Huggert. Xenomerus latimetascutum Szabo is transferred to Trimorus. Xenomerus atomus Rajmohana & Narendran, Xenomerus indicus Mukerjee, Xenomerus solox Kozlov et Lé, Xenomerus forax Kozlov et Lé and Xenomerus flavicornis Dodd are considered species of uncertain status (holotypes not aviable). An identification key is provided, and four species groups are proposed.

New species‐group of brachypterous Idris Förster, 1856 s.l. (Hymenoptera: Platygastridae s.l.) from the Oriental region

“…Terminology for morphology follows Masner (1976, 1980), Mikó et al . (2007, 2010), Talamas et al . (2015, 2017), and for sculpturing, Harris (1979).…”

A new species of Phlebiaporus (Hymenoptera: Scelionidae: Telenominae) from India, with first description of the male of the genus

“…Morphological terminology follows Masner (1980) and Mikó et al (2007Mikó et al ( , 2010Mikó et al ( , 2016. All the specimens were collected by yellow pan traps (YPT), pit fall traps (PFT) and sweep netting (SN).…”

“…The following abbreviations are used in the description of the taxa. All the measurements are taken as per Mikó et al (2010). HL = head length; HW = head width; HH = head height; FCI (frontal cephalic index) = HW/HH; LCI (lateral cephalic index) = HH/ HL; A1-A12 = antennomeres 1-12 (A1 = scape, A2 = pedicel); L = length; W = width; H = height; OOL = ocular ocellar line; POL = posterior ocellar line; LOL = lateral ocellar line; IOS = interorbital space; T1-T2 = Metasomal tergites 1 to 2.…”
