Taxonomic observations
.
Blepharidina partita
can be attributed to the species group including
B. bimbiensis
,
B. carinata
,
B. guttulata
,
B. rudeli
and, probably,
B. sedecimguttata
(
Figs 2, 4, 6
,
16, 19
) (see the paragraph “Taxonomic observations” in
B. bimbiensis
). However,
B. partita
is recognizable by the: elytra black, with numerous subrounded and more or less fused yellow patches; pronotum reddish-brown or pale brown, with irregular yellow patches; third and ninth elytral interstriae entirely yellow (
Fig. 16
). Aedeagus is similar to
B. carinata
(
Figs 41
,
52
), but it is distinguishable because of the apex more triangular in ventral view. Basal part of spermatheca is comparatively shorter about as long as the proximal part of the ductus (
Figs 56, 58, 63–64, 67
). Both males and females are moderately variable in size, but with constant morphometric ratios (see Appendix 2). Females generally show more transverse pronotum, higher LE/LP ratio, and slightly shorter antennae.
