The genus Hyrtanella Allen and Edmunds (Ephemeroptera: Ephemerellidae) is distinguished from other Ephemerellinae by larvae that have fully operculate gills and single median spines on the posterior margins of abdominal terga 8 and 9. Eggs have one polar cap and a smooth chorion. Male adults are not known, and female alates cannot be assigned to species, based on present data. The genus probably is endemic to the island of Borneo, and it contains two species: H. christineae and H. pascalae, new species. Hyrtanella pascalae is described based on eggs, larvae, and one male subimago. The larva of H. pascalae is distinguished from H. christineae by its smaller size, blunt genal projections, and smooth forefemora. The male subimago has genital forceps segment 3 elongate.KEY WORDS: Hyrtanella, Ephemeroptera, Ephemerellidae, Ephemerellinae, Hyrtanella christineae, Hyrtanella pascalae, new species, descriptions, Borneo, misidentificationsThe genus Hyrtanella Allen and Edmunds (Ephemeroptera: Ephemerellidae) was described for some distinctive larvae and female adults from the island of Borneo (Allen & Edmunds 1976). The monospecific genus (type species: H. christineae Allen and Edmunds) has been classified in the monogeneric tribe Hyrtanellini (Allen 1980; Allen 1984) of the subfamily Ephemerellinae (McCafferty & Wang 2000). Landa et al. (1982) and Landa and Sold n (1985) provided details about the internal anatomy of Hyrtanella. Edmunds and Polhemus (1990) reported the genus from the Malay Peninsula, northern Thailand, and southern India, but these records probably are based on misidentifications.

AbstractThe Oriental genus Baptista Distant is redescribed and compared with other genera of Old World Microveliinae. The type-species, B. gesiroi Distant, hitherto only known from the type specimens (from Burma), is redescribed and recorded from Thailand. Three new speeies are described: B. femoralis sp. n. (Thailand, West Malaysia), B. digitata sp. n. (Thailand), and B. angulata sp. n. (southern India). These species all live in very cryptic and secluded habitats, like wet litter, small watery holes in rocks, or small cavities under turf along streams. The males of the new species exhibit a remarkable polymorphism in the structure of fore Iegs and pregenital abdomen. A closely related genus, Lathriovelia gen. n., is described with two species, L. capitata sp. n. and L. collaris sp. n., both from West Malaysia. This genus has a head structure which is quite unique within the subfamily.

Klimakodesmus Carl, 1932 is briefly redescribed, rediagnosed, and shown to be an oligotypic genus endemic to southern India and distinct from the particularly similar genus Pyrgodesmus Pocock, 1892, monobasic and endemic to Sri Lanka, by several important features of peripheral and, especially, gonopodal structure. A new species, Klimakodesmus bilobocaudatus sp. nov., is described from Kerala state, India, differing from the sole accepted, and type species K. gravelyi Carl, 1932, from Tamil Nadu state, primarily by the laterally trilobate paraterga, the caudally more deeply bilobate mid-dorsal keel on ring 19, and certain minor details of the gonopodal structure.

The genus Paragolsinda Breuning, 1956 is reviewed. To date, only the type species of the genus, P. fruhstorferi Breuning, 1956 has been known. Two species of the genus Mesoereis Matsushita, 1933, M. tonkinensis Breuning, 1938 and M. obscurus Matsushita, 1933, are transferred to the genus Paragolsinda by the features of external structure judged from the photographs of the type specimen of P. fruhstorferi. A new species, Paragolsinda siamensis sp. nov. from Northern Thailand, is described. The structures of endophallus except for the type species are described with illustrations. The terminology for the structure of endophallus employed in our previous paper is partly modified in accordance with recent references.

A new species of priapiumfish, Phallostethus cuulong, is described based on nine specimens collected from the Vietnam-ese Mekong. This is the third species of the genus, following the type species P. dunckeri (from Malay peninsula) and P.lehi (from northwestern Borneo), and distinguished from them by having: seven serrae on the second ctenactinium in adultmales (vs. five in P. dunckeri and eight in P. lehi); 25–26 caudal vertebrae (vs. 27 in P. dunckeri and 28 in P. lehi); approx-imately 5–19 teeth on paradentary (vs. 15–20 and 28 or more in P. dunckeri and P. lehi, respectively). All six examinedmales are dextral (vs. one and two known males are sinistral and dextral respectively in P. dunckeri, and all four knowmales are sinistral in P. lehi). Sexual dimorphism is also found in the number of precaudal vertebrae, i.e., 13–14 in males and 11–12 in females (vs. sexual dimorphism is not found in number of precaudal vertebrae of P. dunckeri and P. lehi).

The genus Indocloeon Müller-Liebenau 1982 (s. l.) is divided into two subgenera, the subgenus Indocloeon (s. str.) and the subgenus Hindocloeon subgen. n. which differ one from another by certain characters of larvae, winged stages and eggs. The subgenus Indocloeon is distributed in Sri Lanka only and includes two species, Indocloeon (Indocloeon) primum Müller-Liebenau 1982, and Indocloeon (Indocloeon) secundum sp. n., which are described here based on larvae, subimagines, imagines of both sexes and eggs associated by rearing. The subgenus Hindocloeon (type species Indocloeon indonesiae Kluge 2012) is widely distributed in the Oriental region. A new species Indocloeon (Hindocloeon) continentale sp. n. is described from Thailand based on larvae, subimagines, imagines of both sexes and eggs associated by rearing; subimagines presumably placed in this species, are reported from southern India. Some characters of Indocloeon (Hindocloeon) indonesiae Kluge 2012 are illustrated for the first time. The species originally described as Cloeon longistylus Demoulin 1969 is placed in Indocloeon as Indocloeon (Hindocloeon) longistylus comb. n. Subimagines of two unnamed species of Hindocloeon are reported from Vietnam and Java. Keys to known larvae and imagines are given.

AbstractThe Timasius chinai species group is redefined and taxonomically revised. Twelve species are distributed on the Asian mainland from northeastern India to southeastern China and to the Malay Peninsula, on Tioman Island, and on Java. The two earlier described species, T. chinai (Lundblad, 1933) (from Indonesia: Java) and T. miyamotoi Andersen, 1981 (from Thailand and China; first record from Laos), are redescribed. Ten new species are described: Timasius anderseni sp.n. (from Vietnam), T. gracilis sp.n. (from China: Hong Kong), T. indicus sp.n. (from India: Meghalaya), T. laoticus sp.n. (from Laos), T. malayensis sp.n. (from West Malaysia), T. montanus sp.n. (from northern Thailand), T. schuhi sp.n. (from West Malaysia: Tioman Island), T. schwendingeri sp.n. (from northeastern Thailand), T. yangae sp.n. (from West Malaysia: Tioman Island and Selangor), and T. yunnanensis sp.n. (from China: Yunnan). Keys to the species are provided based on external characteristics and on the genitalia of the males.

AbstractThe coroebine genus Coraebosoma Obenberger is revised for the first time with six new species, five described from the Philippine Islands: C. samarense from Samar Is., C. panayense from Panay Is., C. negrosianum from Negros Is., C. sibuyanicum from Romblon and Sibyan Is., C. violaceum from Mindanao Is. and C. indicum, from southern India. The genus is redescribed with the type-species, C. manilense Obenberger, C. carteri Hoscheck and new species diagnostically described. A key to separate the species, illustrations, and a distribution map are presented along with discussion on the generic relationships. The species are cladistically analyzed and supported by an area cladogram.

A taxonomic review of the known Taiwanese taxa of the pericaline Lebiini, this paper includes a key to the genera, keys to species, descriptions, and redescriptions of all species, illustrations, geographic range maps, re-rankings, and new synonymies. In total 34 species are treated, nine of which are described as new. A new genus and new species are as follows:Bellavalentisgen. n., (type speciesDolichoctiskuzugamiiShibata, 1967);Amphimenesabsensacidussp. n.;Amphimenesbeichatiensissp. n.;Amphimenescarinacaulissp. n.; Catascopus(s. str.)asahartisp. n.; Catascopus(s. str.)viridiorchissp. n.; Coptodera (Coptoderina) occultasp. n.;Dolichoctisbadiadorsissp. n.;Dolichoctisdilatatasp. n.;Moctherusobscurabasissp. n.After close examination of the type material of several species, we were able to determine thatCoptoderinachaudoirianguilipennis(Nakane and Okhura) is a junior synonym of Coptodera (Coptoderina) chaudoiri Andrewes,syn. n.andCoptoderanobilisJedlička is also a junior synonym ofC.chaudoiri,syn. n.DolichoctisstriatusformosanusHabu is a junior synonym ofDolichoctisrotundata(Schmidt-Goebel),syn. n.Dolichoctis (Mochtherus) uenoi Habu is a junior synonym ofMochtherusluctuosusPutzeys,syn. n.PericalusformosanusDupuis was recently ranked as a subspecies ofPericalusornatusformosanusDupuis. After consideration of the several consistent taxonomic characteristics and also considering its allopatric distribution with all other species ofPericalus, we believePericalusformosanusDupuis to be a valid species,stat. resurr.The monobasic genusPseudomenarus(type speciesPseudomenarusflavomaculatusShibata, 1964) is established as conspecific with members of the genusFormosiellaJedlička, 1951,comb. n.Species previously recorded from Taiwan that are not present here include:AmphimenespiceolusBates;CatascopusaequatusDejean;Catascopusfacialis(Wiedemann)CoptoderainterruptaSchmidt-GoebelCoptoderaflexuosaSchmidt-Goebel andPeripristusater(Laporte). The pericaline taxa of Taiwan are arranged in 14 genera, five subgenera, and 34 currently known species. Notes on collecting circumstances, habits, and habitat are included when known.

The tribe Polydrepanini is rediagnosed through an elongate, mostly slender, sometimes twisted/helicoid gonofemorite and a more or less thin, mostly flagelliform, suberect, apical or subapical solenomere often forming a conspicuous loop/curve near the base. The tribe presently encompasses seven genera, all redefined, illustrated and keyed: Dasypharkis Attems, 1936, stat. revalid., Delarthrum Attems, 1936, Grammorhabdus Carl, 1932, stat. revalid., Pocockina Jeekel, 1965, Polydrepanum Carl, 1932 (= Gyrodrepanum Carl, 1932 and Hindomorpha Golovatch, 1984, both syn. nov.), Telodrepanum Carl, 1932, and Xiphidiogonus Carl, 1932. The genus Polydrepanum is shown to currently comprise only four described species, all also redefined, depicted and keyed: Polydrepanum tamilum Carl, 1932 (the type species), P. horridum Golovatch, 1984, P. granuliferum (Attems, 1936), comb. nov. ex Hindomorpha, and P. lamprum (Chamberlin, 1920), comb. nov. ex Gyrodrepanum. Grammorhabdus fissus (Sankaran & Sebastian, 2018) is formally transferred from Polydrepanum, comb. nov. Because Polydrepanum implicatum Carl, 1941 shows a strongly shortened gonopodal femorite, coupled with a distal and flagelliform solenomere, this species is considered as not only somewhat intermediate between the tribes Alogolykini and Polydrepanini as redefined here, but it is formally assigned to Alogolykini as the type species of Carlogonopus gen. nov. (masculine), with C. implicatus (Carl, 1941), comb. nov. ex Polydrepanum, as well as a comb. nov. ex Telodrepanum. A somewhat similar situation concerns Manikidesmus suriensis Bhakat, 2021, a still invalid genus and species from West Bengal, eastern India that likewise shows a clearly shortened gonofemorite. However, this being even more important, Manikidesmus suriensis is a “nomen nudum” not available yet for zoological nomenclature. The large and mainly Himalayan genus Delarthrum is briefly reassessed, mainly in connection with a new species, D. anomalans sp. nov., described from Kerala, southern India and placed in a species-group of its own. Some general considerations concerning the diversity and distribution of the subfamily Alogolykinae are presented.
