Assing, V., 2007, A new species of Megalogastria BERNHAUER from Israel (Coleoptera: Staphylinidae: Aleocharinae: Aleocharini), Linzer biologische Beiträge 39 (1), pp. 39-43 : 43

Key to the species of Megalogastria

1 Winged species, hind wings fully developed; elytra longer (EL/PL: 0.80-0.90). Whole abdomen blackish. Antennomere V distinctly wider than IV. Pronotum more transverse (PW/PL:>1.40). Abdomen gradually tapering posteriad, i. e. widest at base, and more coarsely punctate. Median lobe of aedeagus as in ASSING (in press b: Figs 10 –13). – Turkey: Bitlis, Erzurum ( Map 1 )................................................................ M. alata ASSING

- Hind wings completely reduced; elytra shorter (EL/PL: <0.70). Abdomen bicoloured, with segments III-IV reddish and the remainder blackish. Antennomere V only slightly wider than IV. Pronotum less transverse (PW/PL: <1.40). Abdomen widest in the middle (segment V) and less coarsely punctate. Morphology of aedeagus different. Species from western Turkey or Israel................................................................................2

2 Abdomen larger and broader in relation to forebody (AW/EW: 1.09-1.20) ( Fig. 1 ). Elytra shorter (EL/PL: 0.55-0.60) and more strongly dilated posteriorly. Antennae longer (AL: 0.76-1.07 mm). Median lobe of aedeagus larger (ML: 0.47-0.50 mm), with apically curved and more acute ventral process, and with pronounced crista apicalis ( Figs 7-9 ). Israel ( Map 1 ) ................................................................ M. crassiventris nov.sp.

- Abdomen less broad (AW/EW: 1.05-1.16). Elytra longer (EL/PL: 0.63-0.70) and less strongly dilated posteriorly. Antennae shorter (AL: 0.76-0.82 mm). Median lobe of aedeagus smaller (ML: 0.38-0.42 mm), with apically straight and less acute ventral process, and with weakly pronounced crista apicalis (ASSING in press a: Figs 132-133). Western and northwestern Turkey ( Map 1 )................................ M. cingulata (EPPELSHEIM)
