Please note that all of the attached images are "general idealized" maps since I have no idea of the landforms of Nuelan. To be more specific with these maps, I would need to know where the mountain ranges are, and their topographic and geopspatial ranges. For good examples of how mountain ranges can affect these "general idealized" maps, look to the Himalayan and Andean ranges here on Earth.
Also, the world's axial tilt will play a large role on how the climate and atmospheric flow zones will shift north and south as the world revolves around the primary (sun) and the seasons change. The maps I created below are based on an axial tilt like Earth (23° 26' 16" or 23.438°) and a revolution period like Earth.
I also added 60° latitude lines (red) on all the maps (explained below).
As before, the white arrows show the direction of rotation.

These images have the red lines showing the 60° latitudes. I added these because the "general idealized" atmospheric flow will be in regions 0° to 30°, 30° to 60°, and 60° to 90° (the poles) in both north and south latitudinal regions. As mentioned before, I had the 70° latitudes to show where the primary polar climates will be.
This is a nice tutorial made by jbgibson of how the General Atmospheric Flow can develop on a world.

Again, remember that this is a "general idealized" map. It should give you a good idea on how the climates will be around Nuelan. If not, then ask and I or others here will be glad to answer.
Region of Interest
And to answer your question. The region of interest (ROI) in question will actually have varied biomes. Along the equator, the equatorial region of the ROI will be tropical rainforest/tropical deciduous forest. As you go northward and southward towards the subtropical highs, the biomes will phase through tropical deciduous forest to troical scrub to tropical savannah to semi-arid and arid desert.

This map shows the general idealized climate zones and the ROI. Hope this is the ultimate helper.
And as always, if I made any serious errors, the kind folk here will correct me, please.
