Remarks. Dissomphalus wusheanus was the most abundant species in the collected material, representing 42% of the specimens. D. wusheanus was previously known only in Taiwan , where only three specimens had been recorded ( Terayama 2001 ). As a result of the present study, it has also been identified in Thailand , which might point to a potentially wider scope of distribution encompassing the neighboring countries. Upon visiting South China Agricultural University, the second author found hundreds of specimens of this species collected from Hainan , China , which strengthens the hypothesis postulating a wider area of distribution. Dissomphalus wusheanus is similar to D. ferrurus sp. nov. because of the following characteristics: compact appearance of aedeagal dorsal body with inner lobe widely exposed, wider medially; and basiparamere narrow in dorsal view and wide in ventral view. However, in D. wusheanus , the base of paramere is wider than basiparamere apex; the basivolsella has no projection; the lateral margin of aedeagal dorsal body is slightly sinuous; and the ventral ramus is narrow apically.
