Pseudolanurgus minutissimus ( Schedl, 1961) , combination in Jordal, 2021b

Type material. Holotype, female: Madagascar, Scierie à Périnet, 16.xi.1952, Dr K.E. Schedl [ MNHN] . Paratypes (2): Betsatsakry prés Périnet 17.xi.1952 [2, NHMW] .

Diagnosis. Length 1.3 mm, 2.6 × as long as wide. Female frons lightly concave with a distinct transverse crest of short setae along the upper margin of concavity; female scapus triangularly elongated with dorsal tuft of setae almost as long as the eye.

Distribution and biology. Madagascar. Known from the areas of Andasibe (Périnet), Ambila and Montagne d’Ambre ( Schedl 1977). Breeds in Eugenia (Myrtaceae) and Leptolaena pauciflora (Sarcolaenaceae) .

Remarks. This species could be mistaken for Lanurgus given the less inflated elytral apex compared to other Pseudolanurgus species. However, the apical tergite is truncated, the elytral apex is more extended than for the consistently non-inflated Lanurgus , and all interstrial setae are in uniseriate rows.
