Youre welcome. I think i have thought that it looks similar to Araneus stella, but again the spines are weird

Has anyone seen and identified these large (~10mm) male araneids before? Longitudinal fovea, shoulder horns and stout tibia II with a distal pair of spines.

Not many araneids have large males so that narrows down quite a bit. Specimens found in Singapore.
I do have a male specimen from Java. It looks like it "might" be similar to Araneus s.s., but the way the spines look (esp. what appears to be the mating spine) made me wonder if this is just superficial and instead closer to australasian backobourkines

Just realized how smaller it is so probably not D. gigas but something with similar coloration
Just identified this observation as Serendib, a rather rare ant-mimicking corinnid spider. This particular one seem to be mimicking D. gigas, but with its abdomen as the head

Any spider people out there recognize this palp? Theridiid (presumably) from corners of walls etc. Inside houses, Colombo, Sri Lanka. A small sketch in a stack of old drawings, 1980s. Must surely be a well known & widely distributed synanthropic spider. Sorry, no habitus sketch or other info.
Absolute unit of a wolf spider. Large lycosids seem to be not as common in Southeast Asia as they are elsewhere. Perhaps in competition with ctenids?
Undescribed Katya from Bali. The genus is (so far) endemic to Indonesia, found on the mountains of Java to Lesser Sundas

"The genus Titanidiops in South-east Asia" by Schwendinger, Huber & Hongpadharakiree (2024)"

The family Idiopidae is now formally recorded in Indonesia with Titanidiops insularis (but might in fact be a separate, cryptic species from the Thai holotype)

The genus Titanidiops in South-east Asia (Arachnida: Araneae: Idiopidae)
Five Titanidiops species are described: T. birmanicus Schwendinger & Huber, sp. nov. (♂♀) and T. tenuis Schwendinger, sp. nov. (♂♀) from Myanmar, T. sayamensis Schwendinger & Hongpadharakiree, sp. nov...

There are 4 well-known species here: Nephila pilipes, Macracantha arcuata, Platythomisus octomaculatus, and Argiope catenulata (missidentified as Nephila antipodiana)
