2.) Male paralectotypes (8d): Similar to the female lectotype. Body 2.8-3 mm long. Antenna with 22 (5d) and 23 (Id) antennomeres (2d with damaged antennae). Head slightly less transverse, 1.7-1.76 times as broad as long. Taxonomic remark

— 1.) Triaspis caudatus may be unambiguously identified with the help of the keys presented by Snoflák (1953: 292-298) and by Tobias (1986: 167-172). 2. ) In 1990 Stadlhoffer (Wien), as referred before, identified the female lectotype of T. arcticus as T. semilissus Snoflák, i.e. he placed (in litt, and indicated it with his label attached to the lectotype specimen of T. arcticus) in synonymy the name arcticus with semilissus. T. arcticus, however, is not conspecific with T. semilissus and, together with T. striatulus (Nees) and T. obscurellus (Nees), the four species are well differentiated from each other, see the key-couplets 22 (31) - 51 (52) in Tobias's key (I.e.). In the key Tobias included T. arcticus as a valid species (cf. couplet 30[25]) which species is differentiated from T. caudatus by a single feature, i.e. by the length of the ovipositor sheath: in T. arcticus it is as long as body, in T. caudatus "significantly" longer than body. On the basis of the examination of several specimens the length of the ovipositor sheath in T. caudatus varies from almost as long as body to more or less longer than body. 3. ) In dorsal view the temple of T. caudatus varies from receded to moderately rounded forms (Fig. 1: a-d). The size and shape of this variation shows a geographical distribution: the receded to strongly rounded temples (Fig. 1 : a-b) restricted rather to Central Europe, the clearly to moderately rounded temple (Fig. 1 : c-d) to the rest of Europe. 4. ) Triaspis caudatus (Nees) is nearest to T. striatulus (Nees, 1816) considering their long ovipositor sheath (i.e. as long as to clearly longer than body), the two species are distinct by a few features keyed: 1 (2) Clypeus 3-3.3 times as wide as high medially, its lower margin truncate and medially with a very small tubercule (Fig. 2). Carapace globose exceptionally somewhat less globose and with strong striation, second tergite about twice as wide behind as long medially (Fig. 3). 9d: (2.5—)3—

3.5 mm T. caudatus (Nees, 1816) 2 (1) Clypeus 2.5 times as wide below as high medially, its lower margin rather weakly biconcave (Fig. 8). Carapace clearly oval and with strong striation; second tergite 1.6-1.7 times as wide behind as long medially (Fig. 11). 9d: (1.4-)2-3 mm T. striatulus (Nees, 1816) Triaspis flavofacies sp. n. 9 (Figs 4-7, 12-13) Material examined (19) — Female holotype: Italy, Piemonte, Castelnuovo DB-AT, 250 m a.s.l., June 1973, leg. D. Gianasso. - Holotype is deposited in the Hungarian Natural History Museum (Department of Zoology), Budapest, Hym. Typ. No. 7872. Etymology — The species name "flavofacies" refers to the yellow face. Description of the female holotype — Body 2.8 mm. Antenna as long as head, mesosoma and two-thirds of carapace combined, with 25 antennomeres. Flagellomeres 1 and 2 equal in length, first and second flagellomeres four times as long as broad apically, further flagellomeres gradually shortening and slightly thickening along flagellomeres 10-14 (these flagellomeres just transverse), flagellomeres 15-22 cubic and attenuating
