Allotrichoma strandi Duda, 1942: 7–9 ; type-locality: „bei Nidden am Strande des Kurischen Haffs” [ Lithuania]; lectotype ♂, des. by Papp [1979] ( Germany, Berlin, Museum für Naturkunde der Humboldt-Universität [ Papp, 1979])

LECTOTYPE EXAMINED: (1) “ Nidden / 7.6.40”; (2) “ A. Strandi / [illegible signs]”; (3) “ Typus ”; (4) “ Lectotypus ”; (5) “Zool. Mus. / Berlin ”; (6) “Hypopyg. / gen. 9.5.91”; (7) “ Allotrichoma / filiforme / Beck. ♂ / det. / M. Krivosheina, 1994” . Lectotype is deposited in ZMHB. The type is double pinned and in an acceptable state. Abdomen was removed, macerated and dissected but was dried out. I placed the remains of the abdomen in a microvial filled with gylcerine .

ADDITIONAL MATERIAL EXAMINED: GERMANY: 1♂, 23.v.2015, Brandenburg, Talsperre Spremberg [51.653°N 14,381°E]; 1♂, 23.vii.2015, Mecklenburg-Vorpommern, beach Mönkebude [53.773°N 13,969°E] .

TAXONOMIC REMARK: Examination of the lectotype of A. strandi confirmed the interpretation of the species given in Stuke [2011] that had been based only on a paralectotype. Allotrichoma strandi is a rare species, but has probably been widely overlooked.

DISTRIBUTION: Besides the two records presented here the species is known from the type material which originated from „bei Nidden am Strande des Kurischen Haffs” ( Lithuania). Zatwarnicki and Hollmann-Schirrmacher [1997] report the species from Berlin ( Germany) and, without any sources, from Poland, Hungary and Macedonia. Therefore , the species is hitherto only confirmed from Lithuania and Germany ( Fig. 30 ) .
