Sensilli (110-118) spindle-form, covered by short cilia, with long stalk (45-53), well-developed oblong head (16) and long, flagelliform distal part (49-53).
Diagnosis: This species is distinguished from others by the following combination of characteristics: body size 514-547x282-325; rostrum weakly protruding anteriorly; transcostula present; prodorsal setae smooth; interlamellar setae similar in length to rostral and lamellar setae; sensilli flagelliform, ciliate; 11 pairs of notogastral setae, thin basally and widened medially, smooth; setae lp directed laterally, [h.
Sensilli (168-176) flagelliform, covered by short cilia.
According to these results, the exceptional extensibility of the silk produced by the Flagelliform
gland is more likely due to the highly disordered state of the molecular chains that have no specific dihedral angle constraints--which would be the case in a given secondary structure.
to irregularly awl-shaped, off-white ("pale pinkish cinnamon").
Two of these glands, the flagelliform and aggregate glands, are unique to the araneoids and from these the viscid catching threads are drawn.
The capture silks spun by the araneoids are derived from the flagelliform and aggregate glands and may be homologous in origin to deinopoid silks.
Whipscorpions (Arachnida, Uropygi) are a distinctive group of arachnids characterized by robust, subraptorial pedipalps, a slender first pair of legs and an opisthosoma ending in a long, flagelliform
spigot on a posterior lateral spinneret produces a supporting axial fiber and the two adjacent aggregate spigots coat this fiber with a viscous aqueous solution.

Males of Porrhomma cavernicola retain the triplet, one flagelliform and two aggregate gland spigots necessary for making araneoid sticky silk (Fig.
