Drepanocerus arrowi Balthasar, 1932

Drepanocerus Arrowi Balthasar, 1932: 64 , Figs. on p. 66.

Five syntypes are deposited in NMPC (ex coll. V. Balthasar):

SYNTYPES (5 unsexed specimens): ‘Giufu-Shan / Szechuan / Em. Reitter [p] // Typus [hw, red label] // Det. Dr. Balthasar [p] / D. Arrowi m. [hw]’.

Current status. Junior subjective synonym of Sinodrepanus rex (Boucomont, 1912) , see JANSSENS (1953), SIMONIS (1985) and BEZDĚK & KRELL (2006).

Remark. The above mentioned synonymy was first proposed by JANSSENS (1953) as a result of revisionary study of the holotype of Drepanocerus rex Boucomont, 1912 and a single syntype of D. arrowi , both deposited in Muséum national d’Histoire naturele, Paris, France. Based on Balthasar’s description, SIMONIS (1985) however indicated, that the syntype series of D. arrowi (now in NMPC) could be a mixture of two different species, both belonging to his new genus Sinodrepanus Simonis, 1985 . Unfortunately, he was not able to study the complete syntype series of this species, nor did he designate a lectotype. The current status of S. arrowi is thus not fully resolved, BEZDĚK & KRELL (2006) provisionally accepted JANS- SENS’ s (1953) conclusions. The complete syntype series of S. arrowi is currently under study by E. Barbero and his coworkers (E. BARBERO, pers comm. 2011).
