Abstract
We present a list of grasshoppers of two families from Ghyalchok, Gorkha district with four new species records for Nepal. The checklist of species is given to provide basic information on the grasshopper diversity of that region. With detailed information of all species recorded and plates with photos from different angles of each species, the present work shall contribute towards a better understanding of grasshoppers of Nepal's Ghyalchok, Gorkha region. This study contributes to future revisionary works on grasshopper diversity and distribution in Nepal. We surveyed 13 different localities of Ghyalchok for three years from 2019–2022, following visual count, while the specimens were collected by using a sweep net or by handpicking where feasible. We recorded 29 species of grasshoppers, of which 26 species belong to Acrididae and 3 species to Pyrgomorphidae. Four grasshopper species, Phlaeoba antennata antennata Brunner von Wattenwyl, 1893; Bibracte burmana burmana Ramme, 1941; Caryanda cachara (Kirby, 1914) and Gonista bicolor (Haan, 1942) are recorded for the first time from Nepal.

Abstract
This paper provides the first occurrence report of Pisaura novicia (L. Koch, 1878) from India, based on male and female specimens collected from the ecozone area of the Great Himalayan National Park Conservation Area, Himachal Pradesh. The distribution of the species ranges from the Mediterranean to Central Asia. The previous Indian records of the genus are only from the coastal belts of Andhra Pradesh and Gujarat, thereby the current study extends the range of Indian Pisaura spp. northwards to the Western Himalayas.

Abstract
This paper reports a new addition to the national bumblebee fauna of the Indian Himalayas. The newly recorded species viz., Bombus cryptarum (Fabricius, 1775) (Hymenoptera, Apidae) is fully described from the Gurez Valley (Jammu and Kashmir) and Panamik (Ladakh) in the Western Himalayan range. Males of the B. cryptarum have thoracic dorsum and T2 lemon yellow without black hairs. Gonostylus with the anterior apical process with long hairs and penis valve greatly broadened and flared outwards. With the addition of a new record, the Indian Himalayan region is now represented by 57 species of bumblebees. The species diagnosis, current distributional range, and host plants of this species are also provided.

Abstract
Baetiella muchei (Braasch, 1978) is recorded for the first time from the Neeru stream of Jammu and Kashmir, India. The variability in larval characters such as size, the shape of the labrum, and the number of the sub-marginal arc of setae in the labrum differs from 12 to 22, degree of fusion of the mandibular incisors, spines on the distal margin of the tergites, distal margin of the paraproct, and the length of cerci are observed from the Indian population when compared to the type specimens. The species number of Baetiella Uéno, 1931 has now increased to six in India. A distributional map of this species is also provided.

Abstract
An updated checklist of the hoverflies including distribution and seasonal occurence data of known species in Nepal is presented. The list is based on all available published literature on taxonomy, biodiversity, ecology, and biological aspects of the syrphid fauna of Nepal up to 2023. A total of 205 species from three subfamilies and 63 genera are known to occur in Nepal. Among the three subfamilies, Eristalinae shares maximum species (111 species, 54%), followed by Syrphinae (90 species, 44%), and Microdontinae (four species, 2%). is presented. Among these, 48 (23%) species are recorded in Nepal only. The distribution of known hoverfly species in the country is not uniform, with the Bagmati (82 species) and Koshi (75 species) provinces having the greatest number of species, while the Madhesh (four species) and Lumbini (one species) provinces having the lowest records. The highest number of species are recorded in May (51 species), followed by July (50 species) and June (48 species). Winter season records are relatively low, and distribution data are still incomplete for some sites. Based on the present review, comprehensive and systematic sampling across the entire country is necessary for further exploration of Nepal's hoverfly fauna.

Abstract
One new species and three new records of Tomocerus have been reported for the first time from India. The new species Tomocerus sikkimensis sp. nov. discovered from Gangtok, Sikkim (India) has been illustrated and described here. The new species differs from others in dental spine number, arrangement and mucro teeth number. Tomocerus (Ocreatomurus) qinae Yu, Yan & Liu, 2016, Tomocerus (Tomocerus) minor (Lubbock, 1862) and Tomocerus (Ocreatomurus) paraspinulus Gong, Qin & Yu, 2018 are the first time reported from the Indian states Arunachal Pradesh and West Bengal respectively. A key to the Indian species of Tomocerus has also been provided.
