Differential diagnosis. Both O. melanopus and O. duftschmidi share longer body (4.7–6.2 mm), elytra (3.2–4.1 mm), antennae (2.4–3.1 mm), longer antennomeres IV–VII (particularly noticeable in antennomeres V and VII where the length/width ratios are always more than 2.0) and length/width ratio of protarsomere I (at least 1.65), and these characters separate them from the other three European species as well. The respective measurements for O. rufocyanea , O. mauroi sp. nov. and O. verae sp. nov. do not exceed 4.6 mm (body length), 3.1 mm (length of elytra), 2.5 mm (length of antennae), up to 2.0 (length/width ratio of antennomere V), up to 1.8 (length/width ratio of antennomere VII) and up to 1.65 (length/width ratio of protarsomere I). Oulema rufocyanea and O. mauroi sp. nov. have also distinctly wider elytra (elytral length/width ratio 1.69–1.87) compared to the longer elytra in O. melanopus and O. duftschmidi (elytral length/width ratio 1.87–2.05).

Oulema duftschmidi is extremely similar to O. melanopus . Both species differ in the shape of flagellum (shorter and more robust in O. melanopus , longer and thinner in O. duftschmidi , cf. Figs 16–18 ) and in the junction of ductus spermathecae and bursa copulatrix (short and abruptly connected to finger-like process of bursa copulatrix in O. melanopus , long and gradually extended in O. duftschmidi (cf. Figs 26, 27 ).

(PETITPIERRE 2000), Sweden ( SILFVERBERG 2004, 2010), Switzerland ( KIENER 1995, present paper), United Kingdom ( COX 1995, 2007, present paper), Ukraine ( SERGEEV 2011). North Africa: Algeria ( BERTI 1989, present paper), Canary Islands ( BERTI 1989, present paper), Madeira ( BERTI 1989, present paper), Morocco ( BERTI 1989, present paper), Tunisia ( BERTI 1989, present paper). Asia: Afghanistan ( LOPATIN 1967, as O. melanopus ; present paper), Armenia ( NESTEROVA & LOPATIN 2002, present paper), Azerbaijan (present paper), China: Xinjiang ( NESTEROVA & LOPATIN 2002), Cyprus (present paper), Iran ( BERTI 1989, present paper), Israel ( BERTI 1989, present paper), Jordan (present paper), Kazakhstan (present paper), Kyrgyzstan ( NESTEROVA & LOPATIN 2002), Lebanon (present paper), Syria ( BERTI 1989, present paper), Tajikistan ( NESTEROVA & LOPATIN 2002, present paper), Turkey ( ÖZDIKMEN & ÖZBEK 2014, present paper), Turkmenistan ( NESTEROVA & LOPATIN 2002, present paper), Uzbekistan ( NESTEROVA & LOPATIN 2002).

LOPATIN (1967) published a series of O. melanopus from Afghanistan, but the voucher specimens deposited in MMBC proved to be O. duftschmidi . We do not know the original data on occurrence of O. duftschmidi in Albania and Andorra as listed by SCHMITT (2010) but due to the confirmed occurrence in adjacent countries we consider the occurrence highly probable.

Comments. Lema cyanipennis Duftschmid, 1825 was described from Vienna and its true identity cannot be recognized from the original description. Duftschmidʼs collection is deposited in the Linz museum. Unfortunately, the specimens are dispersed in the historical collection and their labels were removed, thus it is impossible to recognize the true Duftschmidʼs specimens (cf. GUSENLEITNER 1984).

Lema cyanipennis Duftschmid, 1825 is a junior primary homonym of Lema cyanipennis Fabricius, 1801: 472 (described from Sumatra). REDTENBACHER (1874) explicitly proposed Lema duftschmidi as a new substitute name. The identity of both Lema cyanipennis Duftschmid, 1825 and Lema duftschmidi was fixed by a neotype designation for Lema duftschmidi Redtenbacher, 1874 by BERTI (1989).
