Systematic studies on the Pompilidae occurring in Japan: Genus Platydialepis Haupt (Hymenoptera: Pompilidae: Pepsinae)

Generic characters of Platydialepis Haupt, 1941 are presented. A new species of the genus, P. amamiensis sp. nov. from the Amami Islands, the Ryukyus, Japan, is described, and another species of the genus, P. ryoheii Ishikawa, 1957, distributed in Honshu, Shikoku and Kyushu, Japan, is redescribed.

Systematic study of the genus Cyphononyx (Hymenoptera: Pompilidae) occurring in Japan

Generic characteristics and phylogenetic relationships of the genus Cyphononyx are presented, together with a brief review of the biology of the genus. It is shown that only one species of the genus, C. fulvognathus (Rohwer), occurs in Japan. This species is distributed also in Taiwan and south China, and has hitherto been recognized under the name of C. dorsalis. In addition, two new combinations are presented: Cyphononyx hirtus (Haupt, 1935) (= Cryptochilus hirtus Haupt) and Cyphononyx plebejus (de Saussure, 1867) (= Agenia plebeja de Saussure), both of which were recorded from the Oriental Region.     

Systematic studies on the Pompilidae occurring in Japan: Genus Agenioideus Ashmead (Hymenoptera), supplement

Two species of the pompilid genus Agenioideus occurring in Japan are described: A . ( Agenioideus ) kokyo and A . ( A .) cinctellus . The former is new to science and the latter is recorded from Japan and Taiwan for the first time. A brief summary of the biology of A. cinctellus , distinguishing characters between A. ( A. ) ishikawai Shimizu, 1989 and its relatives, and a key to all Japanese species of this genus are presented. Psammochares cinctellus f. rufa Haupt, 1938 and A . ( A. ) pacificus Lelej, 1994 are newly synonymized with A. cinctellus . A new combination is proposed: A . ( A .) maculipes (Smith, 1870) (= Pompilus maculipes Smith), which is found in Southeast Asia to South Asia. Agenioideus ishikawai is newly recorded from Korea and China.     

Taxonomic notes on the small resin bees Hypanthidioides subgenus Michanthidium (Hymenoptera, Megachilidae)

As part of ongoing investigations on anthidiine bees, the type of Anthidium albitarse Friese was found to be conspecific with one of the two species of the small resin bees Hypanthidioides subgenus Michanthidium. The new combination, Hypanthidioides (Michanthidium) albitarsis, is the oldest name, resulting in Gnathanthidium sakagamii Urban as a new junior synonym. The previously unknown male of the second species, Hypanthidioides ferrugineus, is described and figured, including the genitalic structure and associated sterna. Males and females of Hypanthidioides ferrugineus have been collected from flowers of Cuphea sp. (Lythraceae).

Brood Parasitism in Two Species of Spider Wasps (Hymenoptera: Pompilidae, Dipogon), with Notes on a Novel Reproductive Strategy

A trap-nesting study provided the first documentation of brood parasitism in Dipogon nagasei and in D. iwatai. Dipogon nagasei was found to brood parasitize D. sperconsus, D. conspersus, D. inconspersus, and D. bifasciatus. Dipogon iwatai brood parasitized D. sperconsus, D. conspersus, D. romankovae, and Auplopus carbonarius. Both brood parasitic species are with the subgenus Nipponodipogon, whereas all five Dipogon hosts are in the subgenus Deuteragenia. Comparison of their ecological features revealed that brood parasitism in D. nagasei is considerably more derived than in D. iwatai. Of particular note is the fact that in D. nagasei the female routinely lays up to five eggs on a single host spider, all of which develop into adult wasps without larval cannibalism; almost all Pompilidae previously studied lay only one egg on a host spider.

Taxonomic studies on the ant genus Cerapachys Smith (Hymenoptera,Formicidae) from India

The Indianspeciesof the ant genus Cerapachys Smith are keyed. Twelve species are recognized of which 6 are described as new. The species are: Cerapachys aitkenii Forel, Cerapachys alii sp. n., Cerapachys anokha sp. n., Cerapachys besucheti Brown, Cerapachys biroi Forel, Cerapachys indicus Brown, Cerapachys longitarsus (Mayr), Cerapachys nayana sp. n., Cerapachys schoedli sp. n., Cerapachys seema sp. n., Cerapachys sulcinodis Emery and Cerapachys wighti sp. n. Geographic distribution and group affinities of the new species are discussed. A revised key to the Indian species is provided. The rare ergatoid queens of Cerapachys nayana, Cerapachys schoedli and Cerapachys seema are reported. Formed in response to selective pressures these ergatoid queens have a significant role in dispersal strategies and contribute much to our understanding of the biology of these ants.

Two species of the genus Latibulus are recognized from Japan including a new species, L. hokkaidensis n. sp. from Polistes reparius Sk. Yamane et S. Yamane and Polistes snelleni (Saussure) (Hymenoptera: Vespidae). They are decribed for the seasonal variation (spring and summer forms).

Male polymorphism in some Old World species of Cryptocheilus Panzer (Hymenoptera: Pompilidae)

The hypothesis that males of certain species of the pompilid genus Cryptocheilus Panzer are polymorphic, first proposed by H. Wolf, is examined critically in the light of modern knowledge of the mating systems of Hymenoptera and the known biology of Cryptocheilus species. Speculations are made as to the likely selection pressures operating to produce this phenomenon; nine Old World species of Cryptocheilus are identified as probable examples. The taxonomic implications of the hypothesis are considered; one new generic and nine new specific synonymies are listed, and lectotypes are designated for three nominal species. Two names are retrieved from synonymy for species here recognized as valid. A key is provided for the extreme forms of the males of these species; more detailed treatment must await full revision of Cryptocheilus.
