Resin bees of genus Megachile, subgenera Callomegachile and Carinula (Hymenoptera, Megachilidae) from Thailand with description of a new species

Resin bees of the genus Megachile subgenus Callomegachile sensu lato (Hymenoptera; Megachilidae) from Thailand are reviewed. The 14 species treated include those described or revised in the subgenus Alocanthedon, a junior synonym of Callomegachile (three species), and in Carinula (one species). One new species is described, Megachile chiangmaiensis Chatthanabun and Warrit, sp. nov. The replacement name Megachile parornata Chatthanabun, Warrit and Ascher, nom. nov., is proposed for M. gigas Wu (not Schrottky), which is recorded for the first time outside China. For each species, maps and full label data for the examined material documenting occurrences in Thailand are provided. In addition, global ranges, floral associations, and other life history data are summarized and a key to the Thai species is provided for females

A review of the anthidiine bees (Apoidea, Megachilidae) in Thailand

Bees of the tribe Anthidiini (Apoidea: Megachilidae) are notable pollinators consisting of resin bees, wool-carder bees, and cleptoparasitic bees. Twelve anthidiine species were historically reported in Thailand, though the taxonomic information of the group was needed revising. In this study, 165 (97♀, 68♂) anthidiine bee specimens deposited at the Chulalongkorn University Natural History Museum, Thailand, were examined with material obtained from various museum collections. Specimens were principally collected in Thailand with some from Laos and Myanmar. Here, at least eight genera and 15 species of anthidiine bees are recognized: Anthidiellum (5), Bathanthidium (1), Eoanthidium (1), Euaspis (4), Pachyanthidium (1), Pseudoanthidium (1), Stelis (1), and Trachusa (1). Dianthidium chinensis Wu, 1962, Eoanthidium chinensis (Wu, 1962), Eoanthidium semicarinatum Pasteels, 1972, and Eoanthidium punjabensis Gupta & Sharma, 1953 are relegated as junior synonyms of Eoanthidium (Hemidiellum) riparium (Cockerell, 1929), stat. nov. Both Anthidiellum (Pycnanthidium) latipes (Bingham, 1897) from Phang Nga and Euaspis aff. wegneri Baker, 1995 from Chumphon were identified as new records for Thailand. Trachusa aff. vietnamensis Flaminio & Quaranta, 2021 from Phitsanulok is a new record for the genus found in Thailand, whereas Pseudoanthidium (Pseudoanthidium) orientale (Bingham, 1897) is a new record for Laos. Annotated comments are provided for some taxa and identification keys for the Thai anthidiine bees is provided
