Note.

When Lallemand (1950) described Locris bipunctata atra , he described it as a variety, which according to the article 45.6.4 of the International Code of Zoological Nomenclature ( ICZN 1999) should now be considered as a subspecies. Therefore, Locris bipunctata now contains two subspecies, easily distinguished from each other by the colouration of their tegmina, red for L. b. bipunctata (Fig. 1 ) and nearly completely black for L. b. atra (Fig. 2 ), the latter appearing as a strong melanisation. Geographically, the two subspecies are clearly separated (Fig. 3E ) but from the material examined, no difference can be observed in the male terminalia between the two subspecies. For this reason, we decided to keep them as subspecies and illustrate here only the male terminalia of the paratype specimen of the subspecies L. bipunctata atra (Fig. 3A-D ).

Distribution.

Madagascar (Fig. 3E ), L. bipunctata bipunctata in northern Madagascar, L. bipunctata atra in western Madagascar.

Description of the male terminalia

(Fig. 3A-D ). Pygofer (Fig. 3A ), in lateral view almost trapezoidal with posterior margin being the longest side and slightly cut out in its first dorsal third. Aedeagus consists of two parts, first basal part, representing 2/3 of total length, tubular and almost same thickness over its entire length, curving regularly down then dorsally, and bearing on its apical dorsal part a small hump directed dorso-anteriorly; second part, hanging from first, narrowing in its middle then developing posteriorly a pair of pointed processes and finishing in a smooth and flattened apex slightly digit shaped ventro-posteriorly (Fig. 3B ). Parameres smoothly widening from pygofer’s attachment and finishing posteriorly by a curved spine (Fig. 3C ). Subgenital plates large at base, narrowing quickly in a long and fine structure curving gently dorsally on its apical half (Fig. 3D ).

Body length: 7.5-10 mm.
