Type material. Holotype, female: Madagascar, Perinet , 23. novembre 1952, ex Harungana madagascariensis, K.E. Schedl , leg. [ MNHN] . Paratype, female: Madagascar, Ambila , 28.xi.1952, K.E. Schedl [ NHMW] . Holotype of Lanurgus cribellus , male: Madagascar, Perinet , 16.xi.1952, K.E. Schedl [ NHMW] .

Diagnosis. Body length 1.3–1.6 mm, 2.3–2.6 × as long as wide; colour black; female frons with a broadly triangular tuft of recumbent setae reaching from vertex to middle of frons; setae on elytral interstriae uniseriate, on disc bristle-like, spatulate on declivity; elytral apex extended, lip-shaped.

Distribution and biology. Known from various locations along the eastern rain forest of Madagascar ( Schedl 1977) where it was collected from Harungana (Hypericaceae) and Eugenia (Myrtaceae) , and in this study also taken in flight intercept traps with ethanol or plant oil lures. Several new collections from a Harungana branch 1 cm in diameter contained always two females per male. Galleries were made in phloem with brood sizes 7 to 18, on average 13.1 per female (n=8). Eggs were laid in distinct pits along longitudinally excavated tunnels.

New records. Madagascar, Fianarantsoa, Ranomafana National Park [GIS: -21.253, 47.421], ex Harungana madagascariensis , 29ix2012, B. Jordal leg (20). Same locality, in FIT baited with EtOH (6); FIT baited with cubeb oil (3); Telytakely trail [GIS: -21.261, 47.421], FIT baited with rosewood oil (1); all deposited in ZMUB . Fianarantsoa, Ranamafana Nat. Park , CASLOT MA02-09B-06, 6.xii.2001, B. Fischer, leg. (1) [ CAS] .

Remarks. The unique holotype of Lanurgus cribrellus is badly preserved but proportions and cuticle structures of this specimen are identical to type specimens of P. harunganae .
