Holotype of Ps alluaudi . ♂: ‘ Madagascar | Su[???]ieville’ [blue label, Grouvelle’s hand], ‘Type’ [red label], ‘MUSEUM PARIS | 1917 | Coll. GROUVELLE’ [blue label], ‘ Psammoecus | alluaudi | G. Grouv’ [Grouvelle’s hand] ( MNHN).

Remarks

Pal (1985) gave a redescription of Ps. trimaculatus based on material from Motschulsky’s collection (Museum Moscow) that he accepted as type material. He did not designate a lectotype. The material consisted of five specimens mounted on a single label (Pal 1996, personal communication).

It was not possible for the present author to see this material, but he had the opportunity to study a single, female specimen from Motschulsky’s collection (ZMUM). This specimen is not assumed to be a type, while the material mentioned by Pal may be discovered again.

Pal (1985) provided detailed figures of Ps. trimaculatus , including the male genitalia, and gives an overview on the taxonomy. He states that it occurs in India, Nepal, Bhutan, Sri Lanka, Myanmar, Malaysia, Australia, Japan, and Madagascar. Recently, it has also been recorded as being established in Brasil ( Thomas & Yamamoto 2007).

Both Ps. excellens Grouvelle and Ps. alluaudi Grouvelle are conspecific and have to be synonymised with Ps. trimaculatus Motschulsky.
