Probably a Spiny Assassin Bug nymph (Sinea spinipes) but I can't be certain. Definitely in the Sinea family. There are quite a few of these odd little things lurking in the garden. Bad news for their prey.
36mm + 20 mm extension tubes, handheld, diffused flash.
PP - rotated, cropped, increased saturation on red-yellow, increased contrast, slight dodge/burn on bug, resized, sharpened, added border.
