Two spiders for ID

First was approx 5mm, found in Bristol, possibly a male Linyphia triangularis?

Second also in Bristol, approx 2-3mm, possibly a female Theridion tinctum?

Any help appreciated

The first one is a Metellina sp., the second one is indeed a Platnickina tincta. It used to be called T. tinctum. It was actually also Keijia tincta for a brief period in between.

According to the checklist on the BAS website it still is Theridion tinctum and it doesn't mention any pseudonyms. Are they out of date?

I caught this on video last year, exhibiting its web plucking behaviour

According to the World Spider Catalog, the official name is Platnickina tincta. Everyone is free to disagree, but I have the impression that most arachnologists adhere to the WSC names...
