Allotrichoma trispinum Becker, 1896: 124 ; type-locality: „aus dem Oderwalde bei Maltsch, Schlesien ” [ Poland]; lectotype ♂, des. by Papp [1979] ( Germany, Berlin, Museum für Naturkunde der Humboldt-Universität [ Papp, 1979].

TYPE MATERIAL EXAMINED: Lectotype (♂) of Allotrichoma trispinum Becker, 1896 : (1) “Oderwald / 18/8. 39244.”; (2) “ trispina / Beck.”; (3) “ Lectotypus ”; (4) “Zool. Mus. / Berlin ”; (5) “ Allotrichoma / filiforme / Becker ♂ / det. / M. Krivosheina, 1994”. Lectotype is deposited in ZMHB. The type is double pinned and in an acceptable state. Abdomen had beens removed, strongly macerated and dissected but was dried out. I put the remains of the abdomen in a microvial filled with gylcerine. Sternite 5 is missing.

DISTRIBUTION: As discussed under A. filiforme these two species previously confused with each other and resulted in A. trispinum being ignored by previous authors. Fig. 31 gives an impression of the distribution of A. trispinum based on the records known to the author and the type material from “Oderwald”.
