The region’s climate is of the equatorial hot and humid Am type, according to the current Köppen climate classification... with two well-defined climatic seasons (a rainy season between November and June, and a dry season between July and October) and average annual rainfall ranging from 2200 to 2400mm"

Sampling comments: "Samples were collected on the banks of each stream during two different periods... from November to December 2010 (rainy season) and June to July 2011 (dry season)... Each site was sampled twice for 90 min, on average, by two collectors... Adults were collected according to the protocol of De Marco (1998), which involves sweeping a set area (a 100 m stretch on each bank of the stream and divided into five segments of 20m) with an entomological hand-net"
