Subgenus Parapolybothrus Jeekel, 1963

In 1934 Verhoeff used the name Parapolybothrus for a subgenus including E. electrinus (Verhoeff, 1934) , E. herzegowinensis (Verhoeff, 1900) , E. obrovensis (Verhoeff, 1930) , and E. elongatus (Newport, 1849) . As no type-species was designated the name Parapolybothrus Verhoeff is an unavailable name. By designating E. electrinus as type in 1963 I va lidated the name.

The subgenus is characterized by the absence of a VCm spine and the presence of a VCa spine on the 15th leg, which has a single claw. Projections are present in the 6th, 7th, 9th, 11th and 13th tergites. Ventral spinulation of the 15th leg: 0, 1, 3, 3, 1-2. Male gonopods short, two-jointed, the genital sternite scarcely or not emargmate.

The species referable to this subgenus can be arranged in three categories.

I. The prefemur of the 15th leg of the male inflated just proximad of the middle on the caudal (medial) side. Here belong E. electrinus , E. electrinus ssp. paulianus (Manfredi, 1956) , E. vulcanius (Verhoeff, 1942) , E. frederici (Manfredi, 1947) , and probably, although the male is not known, E. imperialis (Meinert, 1872) . All these species came from Italy; paulianus was described from a cave.

II. The prefemur of the 15th leg of the male with a conical protuberance just proximad of the middle on the caudal (medial) side.

Here belongs only one cavernicolous species from northwestern Jugoslavia, E. obrovensis .

III. Prefemur of the 15th leg of the male without inflation or protuberance.

Here only E. herzegowinensis , from Jugoslavia.

The distinction between the species of the first category is hardly possible, and it seems likely that only one species is actually involved.
