palpal

The specific name is derived from the bulbous lobe of the palpal organ.

Sound is generated when the spider rubs these ridges up and down against the palpal teeth.

It is the only member of the subfamily Spartaeinae with a well-developed palpal conductor.

The genus appears to be allied to Thiodina, but differs in the shape of the palpal organ.

The primary function of the epigyne is to receive and direct the palpal organ of the male during copulation.

The cymbium is a spoon-shaped structure located at the end of the spider pedipalp that supports the palpal organ.

Palpal claw denticulate.

Indicates that despite the similarity of the two genera in male palpal structure, this group of species does not belong in Cytaea.

The palpal tibia of the males are modified in a way that distinguishes them from other mygalomorph spiders of North America.

They also have a paired receptaculum (unpaired in other liphistiids), and have a conductor in their palpal organ.

They have two very long pedipalps with palpal chelae (pincers) that strongly resemble the pincers found on a scorpion.

The genus name is from Latin flex "curved", and crur "leg", and refers to the inner turned palpal tibia of the male.

The specimen's labial palps were still relatively small but also had 6 large palpal setae, and its postocular lobe was rather bilobed.

The epitheton palmatus is Latin for "webbed" and refers to the webbed palpal tibia in dorsal view.

Functional aspects of the male palpal organ in Dolomedes tenebrosus, with notes on the mating behavior (Araneae, Pisauridae).

Specimens from the pubens clade bear yellowish scales on the chelicerae in both sexes, and long palpal tibia in males.

The genus Opopaea, for example, exhibits an expanded palpal patella while male Ischnothyreus are characterized by completely sclerotized, pitch-black pedipalps.

Males have a slender, long embolus originating from the basal half of the tegulum, similar to the embolus of the pubens clade, but a short palpal tibia.

Morphology and homologous features in the male palpal organ in Pisauridae and other spider families, with notes on the taxonomy of Pisauridae (Arachnida: Araneae).

Male spiders of this species possess a stridulatory apparatus which consists of several long bristles on the palpal femur and a series of horizontal ridges on the outer side of the chelicerae.

While the widened palpal tarsus of Filistata hibernalis (Filistatidae) only forms a kind of bulb containing the coiled blind duct, members of the genus Argiope have a highly complex structure.

Larva: The larva has a labial mask short,flat, palps narrow, palpal setae present, premental setae variable, median lobe shallowly cleft; caudal gills saccoid to triquetral, strongly nodate.

The verecunda clade shows sexual dimorphism: males bear rows of long white bristles on the chelicerae and have short palpal tibia, while females have few bristles, but dense white hairs on the clypeus.

Mating ovulation were recorded and the researchers found that males that gave a nuptial gift had better mating success, longer copulations, and longer palpal insertions than those who did not give an nuptial gift.
