Abstract

A total of 16 genera and 68 species of Chalcididae of Vietnam are taxonomically treated.

The genus Phasgonophora Westwood, 1832 (Hymenoptera, Chalcididae) in Saudi Arabia: re-evaluation of its limits and description of three new species

“…The relevant species included all those described from the New World, the west Palaearctic and the Afrotropical regions, and part of those described from the Oriental region. We used keys and descriptions provided by Narendran (1989), Narendran and van Achterberg (2016) for comparison of species described from Saudi Arabia to the rest of the Oriental species. Table 2.…”

“…Phasgonophorinae are parasitoids of wood-boring beetles belonging to the families Buprestidae, Curculionidae (including Scolytinae), Cerambycidae and Anthribidae (Steffan 1951(Steffan , 1973Burks 1959;Mateu 1972;Bouček 1988Bouček , 1992Narendran 1989;Roscoe 2014;Narendran and van Achterberg 2016).…”

“…Phasgonophora with 38 described species is distributed in arid and temperate zones of Asia (21 species), New World (11 species), Africa (2 species) and Australia (4 species). The genus parasitizes xylophagous beetles of the families Anthribidae, Buprestidae, Cerambycidae and Curculionidae (including Scolytinae) (Waterston 1922;Steffan 1951;Burks 1959;Mateu 1972;Narendran and van Achterberg 2016).…”

First record of the subfamily Epitraninae from Saudi Arabia (Hymenoptera, Chalcidoidea, Chalcididae), with the description of three new species

“…Members of Epitraninae are easily recognized by the following combination of characters: absence of cephalic horns; antennae inserted at lowermost part of face, very near to oral fossa on a protrusion or, most often, on a protruding lobe of frons "frontal lobe" (wrongly named clypeus by some authors), masking clypeus; frontal lobe with its free margin either rounded or denticulate, and may be divided by inter-antennal lamella; frons more or less flat; gena with strong posterior carina that extends into a flange; mesoscutellum simple, strongly convex and rounded at posterior margin; propodeum horizontal, its sculpturing clear and well-marked, areola often present medially; tegula flattened sometimes extends into a flange posteriorly to overlap base of hind wing; marginal vein of fore wing extremely long relative to the short stigmal vein and the reduced or absent postmarginal vein; metafemur with a comb of contiguous small teeth or spaced teeth following a large more or less triangular basal tooth; metatibia ending in a curved tibial spine, with a distinct tarsal scrobe, varying in length, that extends to reach a proximal sub-basal prominence; metasoma with a long narrow, striated petiole, several times as long as wide, or in some cases may be longer than half length of the gaster; gastral body rather small, compressed from side-to-side, and bulging ventrally, first gastral tergite occupying almost the total part of metasoma, thus mostly concealing the remaining tergites Bouček 1982Bouček , 1988Husain and Agarwal 1982;Narendran and van Achterberg 2016;Delvare 2017).…”

“…Hosts are known from only seven Oriental (Bouček 1982(Bouček , 1988Narendran 1989;Narendran and van Achterberg 2016;Noyes 2019), and a single Afrotropical species (Sauphanor et al 1987). All of them parasitizing small lepidopteran moths of the families Crambidae, Pyralidae and Tineidae (Bouček 1982(Bouček , 1988Sauphanor et al 1987;Narendran 1989;Narendran and van Achterberg 2016;Noyes 2019). This is in addition of two records, E. chilkaensis (Mani) reared from a nest of Camponotus compressus (Formicidae) (Narendran 1989) and E. emissicius Steffan that was found as living in subterranean nests of Mastotermes sp.…”
