Background

The genus Mannerheimia Mäklin, 1880 comprises several species found in the Himalayan region.
Accurate taxonomic and faunistic data are crucial for understanding insect biodiversity and distribution.

Purpose Of The Study

To present taxonomic and faunistic data for four Himalayan species within the genus Mannerheimia.
To redescribe and illustrate three species: M. cachemirica, M. emodensa, and M. obscura.
To establish a new synonymy and document the distribution of Mannerheimia obscura.

Main Methods

Morphological redescription and illustration of selected Mannerheimia species.
Taxonomic comparison to establish synonymy.
Faunistic data collection and mapping of distribution.

Main Results

Three species, Mannerheimia cachemirica, M. emodensa, and M. obscura, are redescribed and illustrated.
A new synonymy is established: M. cachemirica = M. vicina syn. n.
Mannerheimia obscura is newly recorded from Himachal Pradesh, India, and Nepal, with a distributional map provided.

Conclusions

The study enhances the taxonomic understanding of the genus Mannerheimia in the Himalayas.
New distributional data for M. obscura contribute to conservation and further research efforts.
The established synonymy clarifies the species composition within the genus.
