Diagnosis.

Laccophilus insularum is very closely related to Laccophilus livingstoni , occurring in mainland of Africa. Clear differences in appearance of penis apex show that they are not conspecific, but represent good species (vide diagnosis of Laccophilus livingstoni on p. 250).

Description (Only diagnostic differences from description of Laccophilus livingstoni considered.): Body length 3.0-3.6 mm, width 1.7-2.0 mm. Dorsal, colour pattern uniform; pale spots on elytra may sometimes be in part reduced or expanded (Figs 520-521).

Head: Uniformly pale; posteriorly not darker.

Pronotum: Pale ferrugineous, basally with vague, darker area.

Elytra: Basal, pale markings variable in size; sometimes somewhat extended (Figs 520-521).

Ventral aspect: Apical ventrite (Fig. 198). Stridulatory apparatus distinct; file of ridges quite broad.

Male genitalia: Penis apex distinct; outline rounded and apex expanded both at external and internal edge (Fig. 369).

Female: Apical ventrite (Fig. 199).

Etymology.

The name insularum is a Latin noun in genitive plural form meaning "belonging to the island". It refers to the fact that the new species is only known from Madagascar.

Distribution.

Madagascar (Fig. 578).

Collecting circumstances.

Insufficiently known. At least once collected in a river, in stagnant sites of the water body.
