Two new records of the genus Lepidostoma Rambur are reported from India. These include L. diespiter (Malicky & Sangpradub, 2001) and L. kamba (Mosely, 1939b) collected from Himachal Pradesh and Uttarakhand in India. With these new additions, the genus Lepidostoma Rambur is represented by 51 valid species from India. Complete redescriptions of these two species with illustrations are also provided. Also, L. sonomax (Mosely, 1939) is reported from Uttarakhand for the first time. Potential threats to these species and other freshwater biota are noted.
据报道，印度新记录了两例Lepidostoma Rambur属。其中包括从印度喜马偕尔邦和北阿坎德邦采集的 L. diespiter (Malicky & Sangpradub, 2001) 和 L. kamba (Mosely, 1939b)。随着这些新种的加入，印度的 Lepidostoma Rambur 属共有 51 个有效种。本文还对这两个物种进行了完整的重新描述，并附有插图。此外，L. sonomax（Mosely，1939 年）也是首次被报告来自北阿坎德邦。报告指出了这些物种和其他淡水生物群面临的潜在威胁。

Orthotrichia is the most species rich of the hydroptilid genera found in Australia, and is postulated to be a relatively recent arrival from the Oriental Region. The genus has an almost worldwide but patchy distribution, represented by close to 280 species among which the Australian fauna of 55 species represents around 20%. In an attempt to understand the radiation of the genus in Australia, this paper explores the morphology and biology of Australian species and discusses a number of contrasts with reports on the biology of congeners in the Northern Hemisphere. The possible significance of these differences in Australian representatives of the genus is suggested to have played a role in the ‘success’ of the genus in the region. The value of life history studies to our understanding of biodiversity and biogeography is emphasized.

Comparative study of sensory structures on maxillary and labial palps in 71 species from 14 families by scanning electron microscopy and light microscopy revealed significant diversity of sensory structures. Seven principal types of sensory structures were found: pointed trichoid, blunt chaetoid, campaniform, thin basiconic, thick basiconic, petaloid, and pseudoplacoid sensilla. Pointed trichoid and blunt chaetoid sensilla occur on every palp segment. First and, especially, second segments of maxillary palps have bunches of very large blunt chaetoid sensilla on medial surfaces. Campaniform sensilla were found only on basal segments. Pseudoplacoid sensilla are common on the terminal segments of both labial and maxillary palps except for Ptilocolepidae and Hydroptilidae. The petaloid sensilla forming the sensory fields are found in groups surrounded by the soft cuticle, generally in depressions, on the apical segments either on maxillary and labial palps in Hydrobiosidae and Rhyacophilidae, only on labial palps in other studied Integripalpia, or on apical labial palp segment and third and fourth maxillary palp segments in Annulipalpia. The pointed tips of both maxillary and labial palps in lower families have apical sensory complexes looking like small conical outgrowths without microtrichia, each with one large thick basiconic sensilla on its tip and several shorter thick basiconic sensilla on lateral surfaces. We consider these seven types of sensilla along with the apical sensory complex and the assemblage of the petaloid sensilla as a part of Trichoptera ground plan. This primitive diversity changes in evolution so the apical sensory complex, the fields of petaloid sensilla, the groups of very long blunt trichoid sensilla of basal segments, and the pseudoplacoid sensilla disappear in some advanced instances, more often on the maxillary palps. Interspecific variations of sensilla might be important for species discrimination, while the distribution of certain sensory structures is important for higher taxonomy.

We studied the types of sensilla on the pectinated antennae of Ctenoceratoda species (Noctuinae, Hadenini) using scanning electron microscopy. These ultrastructures are described, illustrated and analysed in four distinct species groups of the genus. The group features distinguishing the four lineages of the genus and their taxonomic importance are discussed.

Within the genus Hylaeus subgenus Deranchylaeus, from sub-Saharan Africa, a distinctive new subgroup of species is established. The females of this subgroup share a striking character: the orange-coloured lower face, previously known only in H. xanthostoma. The inter-specific differences are cryptic in both sexes. Seven species are newly described: Hylaeus (Deranchylaeus) aurantiacussp. nov. ♀♂, H. (D.) burundissp. nov. ♂, H. (D.) lyriformissp. nov. ♂, H. (D.) sambiensissp. nov. ♂, H. (D.) portokaliussp. nov. ♂♀, H. (D.) diastictussp. nov. ♂ and H. (D.) jemeniticussp. nov. ♀. This subgroup also includes H. (D.) promontorii (Meade-Waldo, 1923) and H. (D.) venustus Dathe, 2014, whose females are described for the first time. From Cameroon, the male of a second species of the subgenus Pumilaeus is described as new: H. (Pumilaeus) soukontouaisp. nov. New records of species of the genus Hylaeus F. in sub-Saharan Africa are added and a revised identification key to the subgenus Deranchylaeus is presented, to include the new species.

During the 20th and 21st century, two species of Trichoptera have colonised Iceland. One species is Potamophylax cingulatus and the other is Micropterna sequax. Potamophylax cingulatus was not found in several extensive surveys before 1942, conducted by several entomologists. During a survey in streams in 1974–1978, the species was found to be common in east and north-east Iceland, but the Trichoptera species Apatania zonella was absent, where it was common before 1942. Searching collections of unidentified Trichoptera, a single specimen was found in east Iceland on 30 July 1959. The survey was repeated in 2004–2006 and the species had colonised most streams and rivers in Iceland and A. zonella had disappeared from many of them. Potamophylax cingulatus was first recorded in two light traps in south Iceland in 1997 with two specimens. The catch has increased continuously to 267 in 2022. Micropterna sequax was found in a single light trap at Mógilsá near Reykjavik in 2008. The annual catch has since grown from two specimens to 144. The species was found at Hvanneyri, 40 km north of the original site it was recorded from in 2018 (8 specimens) and, in 2021, it was found in Kjós, 11 km from the original site (one specimen based on a photograph). The dispersal rate for P. cingulatus was about 7–9 km/year, but the dispersal rate for the more recent settler M. sequax was found to be 4 km/year.

We provide first records for 108 weevils species sensu lato (Curculionoidea) to the fauna of Montenegro. During a field trip 203 weevil species were recorded and are listed here. The records of Archarius anatoliensis Voss, 1962 are the first ones from the Balkans and document a further spreading of this species towards Northwest. Echinodera bryneri spec. nov. is described and compared with the sympatrically occurring, morphologically similar species E. romanboroveci Stüben, 1998. The lectotypes of Sciaphobus paliuri Apfelbeck, 1908, and S. polydrosinus Apfelbeck, 1922 conserved in the Georg Frey collection are designated, and illustrated comments on their differentiation are provided. For Leiosoma komovicum Pedroni, 2018 habitat, images of both sexes, a description of the female genitalia, and the presumable host plants are presented.

Five species of Geostiba Thomson, 1858 from the Kakheti region, Northeast Georgia, are described and illustrated: Geostiba (Tropogastrosipalia) angularis spec. nov. (region to the north of Lechuri); G. (Sibiota) tbatanana spec. nov. (Tbatana Range) and G. (S.) gomborica spec. nov. (Gombori Range) of the G. bituberculata group; G. (Sibiota) bulbosa spec. nov. (Gombori Range) and G. (S.) effeminata spec. nov. (region to the south of Abano pass) of the G. carinicollis group. The distribution of Geostiba (Sipalotricha) cingulata (Eppelsheim, 1878) is revised and illustrated; a previous record from Azerbaijan is regarded as probably incorrect (result of mislabeled material). The distributions of the species of the subgenus Sibiota Casey, 1906 recorded from Georgia east of South Ossetia are mapped. Additional records of nine species are reported. The Geostiba fauna of the Caucasus region sensu lato is now represented by a total of 55 named species, 34 of which belong to the subgenus Sibiota. Twenty-six species have been recorded from Georgia.
