Sperchon (Hispidosperchon) senguni Özkan, 1982

Records from Turkey: Erzurum Province—“ Sperchon (Scutosperchon) senguni ” Özkan (1982, 1989).

Remarks. This species has not been recorded since the first description that was based on a single male from Erzurum Province (Özkan 1982, 1989). In the orginal description, Özkan compared Sperchon senguni with S. clupeifer , probably due to the presence of a dorsal shield in the male of both species. However he obviously overlooked in combination with the presence of a large dorsal shield in male, the similarity in palp morphology (palp stout, with inflated P-2 and P-3 distal margins forming strongly developed sheaths flanking base of P-4) with the species from the denticulatus species group. Due to a relatively slender palp Sperchon senguni resembles S. hibernicus Halbert, 1944. Özkan did not mention the presence of a ventral plate between the genital region and posterior margin of the idiosoma, but it is possible that small postgenital platelet (characteristic for S. hibernicus) escaped to the attention of Özkan. The holotype of Sperchon senguni needs to be examined to clarify its taxonomic state.

Distribution: Turkey (Erzurum Province).
