Aedeagi, lateral view, (i) of Bohumiljania; (ii) of Hor- niiis; (iii) oiStenomela (from Verma & Jolivet 2004). The aedeagal structure in spilopyrines in general is primitive, as discussed by Verma & Jolivet (2004). But in Hornius, Stenomela and Bohumuljania it is even more primitive; the primitive features of their aedeagi include: (i) Poor differentiation of the basal hood and the aedeagus proper (Fig. 3)

The aedeagal structure in spilopyrines in general is primitive, as discussed by Verma & Jolivet (2004). But in Hornius, Stenomela and Bohumuljania it is even more primitive; the primitive features of their aedeagi include: (i) Poor differentiation of the basal hood and the aedeagus proper (Fig. 3). (ii) Only moderate ventral curvature of the aedeagus, spread throughout the length of the organ, and not confined to the basal part of the aedeagus proper. In Stenomela, however the curvature is more marked in the basal part of the aedeagus proper. (iii) The ventrally directed basal orifice of the aedeagus is relatively restricted anteroposteriorly. In contrast: (i) In Spilopyra, Macrolema, Cheiloxena and Richmondia the differentiation of the basal hood and the aedeagus proper is somewhat better marked than in the S. American and New Caledonian forms; (ii) In Richmondia, Cheiloxena and to some extent in Spi- lopyra the ventral curvature of the aedeagal tube is more marked than in S. American and New Caledonian spi- lopyrines, and in Richmondia and Cheiloxena this cur- vature is almost as strong as in higher Eumolpinae; and (iii) the anteroposterior extent of the basal orifice is large, specially in Macrolema, Cheiloxena and Rich- mondia (For differences between typical eumolpine and spilopyrin aedeagi see Verma & Jolivet 2004). Thus the aedeagal structure in Hornius, Stenomela and Bohumiljania is more primitive than in the remaining spilopyrines, and almost of the chrysomeline type (For features of the chrysomeline type of aedeagus see Verma 1996).
