Plexippus rubroclypeatus (Lessert, 1927) comb. n.

Figures 4Q , 7P

Habrocestum rubroclypeatum Lessert, 1927: 435 , f. 19 (Dmf).

Habrocestum rubroclypeatum Prószyński, 1976: 155 , f. 279 (m) (copy of Lessert's drawing for comparison).

Documentation studied. Summary of world's literature provided by "Monograph of Salticidae ( Araneae ) of the World 1995-2016. Part I & 2" by Prószyński (2016 a, b) and current literature.

Comments. Enigmatic species of unclear position. Palp disagrees with genus Habrocestum Simon, 1876 , its shape of bulbus and embolus resemble atypical Plexippus , like P. kondarensis , without swelling of embolar basis and lateral, sclerotized, serrated edge. Of the other hand, external appearance of body, especially abdominal pattern and carapace not narrowing anteriorly, differ from Plexippus .

Habrocestum rubroclypeatum Dyal, 1935: 229 (junior synonym, preoccupied by Lessert, 1927) is nomen dubium because cannot be recognized from its original description and type specimen is lost. Its renaming by Roewer as Habrocestum dyali Roewer, 1955c: 1119 is not mandated. Therefore:

Habrocestum rubroclypeatum Lessert, 1927 = Plexippus rubroclypeatus (Lessert, 1927) (tentative transfer based on palp appearance)

Habrocestum rubroclypeatum Dyal, 1935: 229 (not Lessert, 1927) = nomen dubium.

Habrocestum dyali Roewer, 1955c: 1119 (not mandated replacement of a nomen dubium).
