DNA Barcoding is one of the emerging tools in molecular identification of faunal diversity, specifically insect fauna. The Surinam cockroach, Pycnoscelus surinamensis is the only known roach to be obligatorily parthenogenetic, with reported haplotypes. P. surinamensis is well established in Indomalayan, tropical and subtropical regions and substantially documented from India with a phenetic approach. Herewith we report the first set of mt DNA barcode from a vouchered collection for the species from southern Western Ghats India. Discussions are made on the identity of two sequences each of Blatteria species and Pycnoscelus species reported from USA.

Nigrobaetis klugei sp. nov. is described based on nymphs from the Sastha falls of Western Ghats, Southern India. The nymph of Nigrobaetis klugei sp. nov. can be distinguished from other Oriental species of Nigrobaetis by the following combination of characters: (i) dorsal surface of the labrum with 1+3 long simple stout setae on the distal half; (ii) paraproct distally not expanded, with a reduced number of spines on distal margin (three large and two small spines); (iii) paraglossae slender, approximately as wide as glossae; (iv) absence of medioproximal spots in the abdominal tergites and (v) long and pointed triangular spines at the distal margin of abdominal tergites.

This catalogue lists 46 valid species included in 7 genera and two subfamilies of the family Hydraenidae (Coleoptera), recorded from India. The subfamily Hydraeninae accommodates 24 species (5 genera), and Ochthebiinae 22 species (2 genera). We include synonyms, type localities, type depositories, and distribution of the species. The Himalayan region supports the maximum diversity (31 species), followed by Deccan Peninsula (5 species), Western-Ghats (5 species), Northeast (4 species), Gangetic Plains (4 species), Semi-Arid (2 species), and Islands (one species).

Aim: Climate and weather conditions play a crucial role in the dynamics and distribution of ticks and tick-borne diseases. In this study, we explored the influence of a heavy rainfall (flood) occurrence on the seasonal activity and density of host-seeking Haemaphysalis tick vectors in Wayanad district, Kerala, India. Methodology: Wayanad district in Kerala state was selected as the study area. Ticks were collected from December 2017 to May 2019, monthly for five consecutive days by dragging method. Tick density was analyzed with climate data obtained from the meteorological station. Results: The total number of ticks collected post-flood decreased to 59% in Kurichiyad (site 1) and 63% in Muthanga (site 2), and the seasonal nymphal peak density was shifted. A seasonal peak of tick activity was normally observed from December to February. This peak occurrence was missing after flood in the study areas created with waterlogging and vegetation overgrowth. Interpretation: The present study revealed the effect of flood events in the study sites with significant differences in the abundance of five Haemaphysalis tick species during pre and post-flood periods and forest and wildlife habitats. This difference in the changing climatic conditions and increasing annual flood seasons in the Western Ghats may shift this region's ticks questing activity and tick-borne disease ecology.

ABSTRACT. The effect of change in orientation and surface roughness of terrain on the daytime up slope flow is investigated using a 2-dimensional mesoscale model. A realistic orography profile of western ghat is chosen for the purpose. Twelve hour of integrations are performed starting from sunrise. The numerical simulation have shown that the intensity of up slope flows remained practically unaffected by change of orientation of terrain. However, increase in roughness length decreases the intensity of developed flows. For comparison purposes, the results of previous investigators are verified with a change in slope angles.
