Hyères (leg. Yersin). Unspecified number of Ƌ and ♀.

Four Ƌ and ten ♀, all syntypes. A card-mounted Ƌ with labels: “Ƌ Hyères, France, colln. Yersin” [handwritten on ruled white card]; “ Arachnocephalus Yersini Sss. ” [handwritten on pale blue paper]; “ Syntypus ” [printed on red paper]. The specimen is mounted on its back; the right antenna, the last tarsal segment of the right front leg, both the middle legs and the cerci are missing. Two Ƌ on the same card mount with labels: “Ƌ Hyères, France, colln. Yersin” [handwritten on ruled white card]; “ Arachnocephalus Yersini Sss. ” [handwritten on pale blue paper]; “ Syntypus ” [printed on red paper]. The specimen on the left lacks most of the right antenna, all three right legs and the cerci. The specimen on the right lacks the left antenna, left front leg, both middle legs, the right hind leg and the cerci. A ♀ with labels: “ ♀ Hyères, France, colln. Yersin” [handwritten on ruled white card]; “ Arachnocephalus Yersini Sss. ” [handwritten on pale blue paper]; “ Syntypus ” [printed on red paper]. The left antenna, the left front and middle legs and the cerci are lost. Five ♀ on the same card mount with labels: “ ♀ Hyères, France, colln. Yersin” [handwritten on ruled white card]; “ Arachnocephalus Yersini Sss. ” [handwritten on pale blue paper]; “ Syntypus ” [printed on red paper]. The leftmost specimen lacks the left antenna and the right middle and hind legs. The next specimen has lost the right middle leg, the left hind leg and the cerci. The middle specimen lacks most of both antennae and the right middle and hind legs. The next specimen has lost most of both antennae, the right front and middle legs and the cerci. The rightmost specimen lacks both middle legs, the ovipositor is broken towards the tip and the cerci are missing. One Ƌ and four ♀ on the same card mount with labels: “ ♀ [sic] Hyères , France, colln. Yersin ” [handwritten on ruled white card]; “ Arachnocephalus Yersini Sss. ” [handwritten on pale blue paper]; “ Syntypus ” [printed on red paper]. The leftmost specimen has lost the left antenna, the left front leg, the right middle leg and the cerci. The next specimen, the Ƌ, lacks the right middle leg and left cercus. The middle specimen lacks both antennae, the left front leg and the right middle leg. The next specimen has lost the right antenna, right front leg and left cercus. The rightmost specimen lacks both cerci; the left middle leg is detached and glued underneath the thorax.
