Revision of the Palaearctic brood parasitic genus Nipponodipogon Ishikawa, 1965 of spider wasps (Hymenoptera: Pompilidae: Pepsinae)

Abstract

The systematics and bionomics of the Palaearctic brood parasitic genus Nipponodipogon Ishikawa, 1965 are revised. Seven species are listed. A new species N. sudai Shimizu, sp. nov. (Japan, Honshu) and the hitherto unknown males of N. iwatai (Ishikawa, 1965) and N. nagasei (Ishikawa, 1965) are described and illustrated. Six species from Japan and the Russian Far East are redescribed. A key to species is provided.

First record of the genus Nipponodipogon Ishikawa, 1965 (Hymenoptera: Pompilidae) from India with description of a new species

“…The new species belongs to the genus Nipponodipogon Ishikawa, 1965 based on the female having the following set of characters: the maxillary cardo with a few thin, light brown bristles, the apex of those not extending beyond the maxillary lacinia; the antenna short, stout, and thickened toward the middle of the flagellum (fusiform); flagellomere 1 length less than 3.0 × its width; the supra-antennal area of the frons produced anteriorly into a frontal ledge overhanging the antennal radicle (Shimizu et al 2015).…”

“…10, 12 -specimen from Japan, Fukui Pref. ; 11 -holotype (from: Shimizu et al, 2015). 10, 11 -head, frontal view; 12mesosoma, dorsal view.…”

“…The genus is known from East Asia, both Palaearctic and Oriental parts. The revision of the seven East Palaearctic species of this genus, with data on their taxonomy, distribution, and biology was given by Shimizu et al (2015). Later, three species were discovered from the Oriental Region for the first time (Loktionov et al, 2017;Loktionov & Lelej, 2018).…”

To the knowledge of genus Nipponodipogon Ishikawa, 1965 (Hymenoptera: Pompilidae, Pepsinae) from Laos

“…The East Asian genus Nipponodipogon Ishikawa, 1965 (Pompilidae: Pepsinae, Deuterageniini) is distributed from the south of the Russian Far East (Amur Prov., Primorskij Terr., Kuril Islands: Kunashir) and Hokkaido in the north (Shimizu et al, 2015;Kochetkov, 2017; to China (Yunnan and Hainan) and Kyushu in the south (Shimizu et al, 2015;. Currently the genus consists of ten species, including new one described below from Laos.…”

“…Currently the genus consists of ten species, including new one described below from Laos. The revision, biology and distribution of the species were given in Shimizu et al (2015) and descriptions of two species from China see . Here Nipponodipogon is newly recorded from Laos.…”
