Graphosoma lineatum (Linnaeus 1758)

( Figure 4 )

Spermathecal bulb is semi-oblong ( Figs. 4 .a,b). Apical region of spermathecal bulb has multiple pores, but there are no pores in the remainder ( Figs. 4 .b,c). Distal and proximal flanges are of equal diameter ( Fig. 4 .b). Pumping region with distal and proximal flanges smooth ( Figs. 4 .b,d,e). Length of distal spermathecal duct about one third that of proximal ( Fig. 4 .a). Distal and proximal spermathecal duct is a muscular structure ( Figs. 4 .f,h). Median portion of spermathecal duct dilated with thin muscular walls. Its muscular walls regularly textured ( Figs. 4 .g,h). Within median spermathecal dilation, sclerotized rod dilated at posterior portion ( Fig. 4 .a). Proximal spermathecal duct is made up of tranverse muscular fibers ( Fig. 4 .h). Two sclerites near opening of spermathecal duct; one circular and the other V shaped. Two ring sclerites at both lateral sides of genital chamber with opening of proximal duct ( Figs. 4 .a, ı, i).
