“…Collection and research activities in this region were strongly increasing during the last two decades. Consequently, several new genera and subgenera of Baetidae were recently described, and other genera were recorded the first time ( Kaltenbach et al 2020b , 2021 , 2022 , 2023 ; Kluge 2020a , 2020b , 2022 ; Kluge and Suttinun 2020 ; Suttinun et al 2020 ; Phlai-ngam et al 2022a ).…”

Material collected on different islands across South Asia revealed a new genus of Baetidae with a widespread distribution, Arcobaetisgen. nov. The larvae present important similarities with Nigrobaetis, but have paraglossae dorsally with an arc of long, spine-like setae in distal area; long, slightly feathered setae between prostheca and mola of both mandibles; and very slender legs with row of short setae at dorsal margin of femur. The male imago has an extraordinarily small 3rd (apical) segment of gonostylus, which is much narrower than the apex of the 2nd segment. The new genus includes five species: A. sumbawensissp. nov. is described from Sumbawa (Indonesia) based on larvae, A. sumatrensissp. nov. from Sumatra (Indonesia) based on larvae, A. bornensissp. nov. from Borneo (Brunei) based on larvae, and A. sripadaisp. nov. (type species) is described from Sri Lanka based on a reared male imago with its larval and subimaginal exuviae; A. gracilentus (Chang & Yang, 1994), comb. nov. from Taiwan, formerly described in Margobaetis Kang & Yang, 1994, a subgenus of Baetis Leach, 1815, and subsequently transferred to the genus Nigrobaetis Kazlauskas (in Novikova & Kluge), 1987, is transferred to the new genus. A key to the larvae of all species is provided. Morphological similarities and the relationship of the new genus to other genera of Baetidae are discussed.

The taxon Securiops Jacobus, McCafferty & Gattolliat 2006 is treated here as a subgenus of the genus Procloeon Bengtsson 1915; it shares all characters of Procloeon s. l. and besides them, has peculiar autapomorphies in mouthparts structure. Diagnoses of Cloeon/fg1 (or the tribe Cloeonini sensu Kluge 2016), Procloeon/g1 (or the genus Procloeon sensu Kluge 2016) and Securiops are given. Larvae of the South African species Procloeon (Securiops) falcatum (Crass 1947) comb. n. are described for the first time. Based on reared specimens from Zambia, larvae of Procloeon (Securiops) macafertiorum Lugo-Ortiz (in Lugo-Ortiz & McCafferty) 1996 are redescribed; subimagines, imagines and eggs of this species are described for the first time. New larval characters of Procloeon (Securiops) mutadens (Jacobus et al. 2006) comb. n. are reported based on a larva from Gambia. Based on reared specimens from Thailand, larvae of Procloeon (Securiops) primasia (Kaltenbach et al. 2023) comb. n. are redescribed; subimagines, imagines and well-developed eggs of this species are described for the first time. Genitalia of Cheleocloeon excisum (Barnard 1932) are figured for the first time.

Based on material recently collected in northern Thailand, the present study provides an updated of the genus Baetiella, including Gratia. It comprises six species in Thailand, three of them being new species: Baetiella (Gratia) narumonae, Baetiella (Gratia) sororculaenadinae, Baetiella (Baetiella) bispinosa, Baetiella (Baetiella) baeisp. nov., Baetiella (Baetiella) lannaensissp. nov. and Baetiella (Baetiella) bibranchiasp. nov.Baetiella (Baetiella) baeisp. nov. can be distinguished from other species by the reduction of the posteromedian protuberances on abdominal tergites I–III, the asymmetrical coniform terminal segment of labial palp, the distal margin of abdominal sternites VII–X each with a row of long, spatulate setae, the dorsal margin of femur with two long, robust setae distally. Baetiella (Baetiella) lannaensissp. nov. is diagnosed by the posteromedian protuberances present on tergites I–VIII, dorsal margin of femur with a regular row of long, rounded, ciliated setae and body surface covered with numerous, dense, rounded scale-like setae. Baetiella (Baetiella) bibranchiasp. nov. can be separated from other species by coxal gills present at the base of forelegs and midlegs. The molecular study based on the mitochondrial gene COI and a larval key to species of Thai Baetiella are also provided.
