Lycosidae (family)

The eye arrangement is wrong to be a member of the jumping spider family.

Patterning might change or be a variation of another genus, but I thought patterning, particularly on the abdomen (but also the rest of it too), best matched Artoriopsis sp out of the Lycosidae spiders I could find (which I think it falls under from it's posture eyes, and general shape). The link above says "Their body size ranges from 3 to 11 mm, with males smaller than females.", indicating it is within size range. Then it says "They appear to prefer open, vegetated or sandy areas of moderate humidity." which matches Jerra Wetlands. The individual in the images in the link also appear to be quite similar to this one. It's suggested there that they are either A. expolita or A. melissae: "Artoriopsis expolita comb. nov. is a common spider in open, moderately moist environments and can frequently be found near creeks and rivers, in fore dunes, on pasture and suburban lawns. Artoriopsis melissae appears to occupy similar habitats as A. expolita i.e. open areas such as lawns, grassland and pasture. Some specimens have also been found in open woodlands and near creeks." Both of which are possible, and other species under Artoriopsis could fit too.
Also, looking at the 2017 version of Robert Whyte and Anderson's book, it says under Artoriopsis sp. on page 172 that "the black diamond shape bisected by a pale stripe on the abdomen helps distinguish this genus" and this individual does have a diamond-shaped black segment towards the front of the abdomen which is bisected by a white/cream stripe.

Another possibility, I think, it Artoria sp which seems to have a pale stripe down the abdomen too, but I believe that this one is Artoriopsis sp since it does have the diamond-shaped black pattern and it's similar to images I have found of it, whereas Artoria sp seems to have more features that differentiate from this one.

Yumi - Artoriopsis does look like a good bet. Too bad we don't have more (and closer) shots.

Thanks Yumi and Kim

Wow thanks for all the effort you went to apologies for my poor photography
