Acrorrhinium inexpectatum ( Josifov, 1978) , new record to China

( Figs. 7 , 11 , 24–27 )

Cinnamus inexpectatus Josifov, 1978: 279

Acrorrhinium inexpectatum Kerzhner, 1988: 72 ; Schuh, 1995: 214 Specimens examined: CHINA: Hebei Province: 2 males, Wulingshan Mountain (40°36'N, 117°29'E), Xinglong County, 28. VIII. 1973, Sheng-li Liu leg..

Diagnosis: Recognized by the ant-mimetic appearance ( Fig. 7 ), the brown coloration of the dorsum with many small irregular spots, the light yellow-brown membrane with its veins distinctly visible, the longitudinal sulcus on the vertex not reaching the posterior margin of the vertex, the elongate spiniform frons with the apex weakly curved and tapering ( Fig. 11 ), the extremely long labium almost reaching the abdominal segment VII, the head and hemelytra covered with sparse, short, sericeous setae and simple setae, the relatively small scutellum with the central part weakly convex, and the male genitalia: vesica strongly sclerotized, twisted, apex with a slender and bifurcate projection, secondary gonopore well developed ( Fig. 24 ); hypophysis of left paramere slender, weakly curved with apex blunt ( Fig. 25 ), right paramere leaflike, lamellate ( Fig. 26 ), phallotheca weakly curved ( Fig. 27 ). It is most similar to A. rhinoceros Distant in coloration and body appearance, but can be separated from the latter by the form of its spiniform frons and the structure of the male genitalia; spiniform frons of A. rhinoceros relatively small, short, and blunt.

Distribution: China (Beijing, Hebei); North Korea.
