| The male palpi are large for the size of the spider, and the palpal organ extends back beyond the tibia. |
| The tibia of the palpal organ has a short, pointed process, extending directly outward from the side. |
| The sperm is then absorbed with the palpal organ, where it is stored until mating. |
| The palpal organ has two appendages at the end, one hard and roughened and the other soft. |
| And if you're more interested in how arachnids do it with palpal specializations than molluscan harpoons, I've got an article on how spiders mate. |
| The male palpi are long, with large tarsi and palpal organs and a long hook on the outer side of the tarsus. |
