Hozman (cVog)  .

C o m m e n t: The original description is based on numerous syntypes from "Anglia mer." collected in " Sphagnum in the spring and autumn" ( SHARP 1915). MUONA (1991) designated a lectotype.

D i a g n o s i s: Wing-polymorphic species.

♂: sternite VIII ( Fig. 18View Figs 18-28) strongly transverse, posterior margin obtusely produced in the middle; median lobe of aedeagus approximately 0.23-0.24 mm long and shaped as in Figs 19-22View Figs 18-28; apical lobe of paramere blackish.

♀: posterior margin of sternite VIII convex, in the middle truncate or weakly concave ( Fig. 23View Figs 18-28); spermatheca comma-shaped, very stout and short ( Figs 24-28View Figs 18-28).

Although very similar in external characters and in the morphology of the aedeagus to M. exilis  , M. exillima  is reliably distinguished by the shape of the male sternite VIII and by the much shorter and stouter spermatheca.

C o n f i r m e d d i s t r i b u t i o n: South England, Spain, France, Germany. Note that, aside from the type material, MUONA (1991) had seen only a single specimen from North Germany.

N a t u r a l h i s t o r y: The type material from South England was collected from Sphagnum, where it "though local is by no means rare" ( SHARP 1915). The material listed above was found in sandy Calluna heathlands, partly also in very sparsely vegetated plots, primarily by extracting soil. One specimen was collected in a bog and one was extracted from a mole nest. The ovaries of five dissected females collected in April contained mature eggs.
