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.

Resin bees of genus , subgenera and (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 (three species), and in (one species). One new species is described, Chatthanabun and Warrit, The replacement name Chatthanabun, Warrit and Ascher, , is proposed for Wu (not Schrottky), which is recorded for the first time outside China.

Two new species of the Southeast Asian Dwarf tarantula genus Phlogiellus Pocock, 1887 (Theraphosidae, Selenocosmiinae) and a discussion on the taxonomic problem of the genus: Addendum.

Sivayyapram et al. (2020) omitted to note the full type deposition of Phlogiellus daweiensis and Phlogiellus raveni; that is corrected herein.

Two new species of the Southeast Asian Dwarf tarantula genus Phlogiellus Pocock, 1887 (Theraphosidae, Selenocosmiinae) and a discussion on the taxonomic problem of the genus.

Phlogiellus is one of the least studied theraphosid genera; there is only one recent revision on the genus. However, the "revision" only provided several taxonomic problems in the genus by giving unclear diagnostic characters of the genus and its species, using third party information in their descriptions and many of their examined specimens of are inaccessible. Here, we discuss the taxonomic problems of the genus, and provide a new genus description and diagnostic characters of Phlogiellus by combining information from previous studies with our examinations.

Records and redescription of a mygalomorph spider genus ignored for over 100 years with a new species: the genus Atmetochilus Simon, 1887 (Araneae, Nemesiidae) in Thailand.

The wishbone spider of genus Atmetochilus Simon, 1887 (Nemesiidae: Bemmerinae) containing six species and is known from Asia. We describe a new Thai species, Atmetochilus songsangchotei sp. nov.

The arctic and alpine bumblebees of the subgenus Alpinobombus revised from integrative assessment of species' gene coalescents and morphology (Hymenoptera, Apidae, Bombus).

The bumblebees of the subgenus Alpinobombus of the genus Bombus are unusual among bees for specialising in many of the most northerly vegetated arctic habitats on Earth. Most named taxa in this group (37 available names from a total of 67 names) were described originally from differences in the colour patterns of the hair. Previous revisions have shown unusually little agreement, recognising a range of 6‒9 species, in part because of pronounced intraspecific variation in both skeletal morphology and in the colour patterns of the hair.
