| Abstract: The present study elucidates the taxonomic composition, seasonal distribution, and diversity gradients of Hemipteran assemblages within Mokhada Tahsil of Palghar district, a biogeographically transitional zone situated along the eastern escarpment of northern Western Ghats. Employing standardized, stratified field-sampling protocols across pre-monsoon, monsoon and post-monsoon periods (2023-2024), a total of 54 species belonging to three suborders namely Heteroptera, Auchenorrhyncha and Sternorrhyncha, were documented. Heteroptera emerged as the dominant clade, representing 77.8% of species richness, with Pentatomidae alone contributing over 51.9% of the total assemblage. Alpha diversity indices revealed a pronounced seasonal gradient, with monsoon exhibiting peak species richness (S=51), Shannon–Wiener diversity (H’=3.79), and evenness (J’=0.89), indicative of community complexity under resource-replete conditions. Diversity metrics attenuated in post-monsoon (S= 46; H’=3.51) and sharply declined pre- monsoon (S=26; H’=2.68), reflecting habitat contraction and increased dominance by drought-resilient taxa. Beta diversity analysis using Bray–Curti's dissimilarity coefficients delineated compositional turnover across seasons, with the highest dissimilarity observed between monsoon and pre-monsoon (0.627), and the lowest between monsoon and post-monsoon (0.312). This investigation contributes a novel, seasonally stratified baseline inventory of Hemiptera for the Mokhada a region, underrepresented in Indian entomological literature and underscores the functional sensitivity of Hemipteran communities to monsoonal hydroclimatic cycles. |
