Olmi, M.: Dryops kaszabi sp. n. from Hungary (Coleoptera, Dryopidae)

96 M. OLMT Types: holotypus çf and allotypus 9 are labelled "Tabdi, 27. V. 1950, rostálás (= sifting), legit DR KASZAB"; the paratypes are 22 (18 from Tabdi, 2 from Ócsa, 1 from Siófok, 1 from Fünfkirchen). Holotypus, allotypus und 17 paratypes are in the collection of the Hungarian Natural History Museum, Budapest ; 1 paratype is in the collection of the Civic Museum of Natural History of Milano ; 4 paratypes (2 çf'çf, 2 Q Q ) are in my collec­tion. Description — Body length: 4.74-5.11 mm ; antennae ten-segmented; aedeagus (Fig. 1) with internal sac for greater part everted; rod of internal sac present and divided at distal apex into two branches provided with teeth; ever­ted part of internal sac with specks along almost entire rod of internal sac; para­meres with mosaic of polygonal surfaces on their inner side, without papillae; 9 with fully developed ovipositor; ductus spermatecae very short; vagina (Fig. 2) with 2 groups of sclerotized pieces: near apex, where ductus spermatecae and even oviducts originate, there are 3 pieces (1 odd provided with 1 tooth; 2 even provided with 3-4 teeth); near ovipositor, there are 2 sclerotized even pieces ("plates") provided with 2-4 teeth. Notes — D. .kaszabi is a unexpected species because it was found in Hun­gary, the birth-place of REITTER, the famous coleopterist who also studied Dryopo­idea. REITTER, probably collected this species, but mistook it for D. griseus (ERICII­SON). The chief diefferences between the two species are on the inner side of the parameres: in D. griseus no sculpture or structures is present; in D. kaszabi there is a clear mosaic of polygonal surfaces. Also the everted part of the internal sac is different : in D. kaszabi there are no spines ; on the other hand, the spines are pre­sent in D. griseus. In D. kaszabion the everted part of the internal sac besides there is no mosaic sculpture between the region ornamented with specks and the region with spines; this is a characteristic of D. griseus. In the key of Palaearctic Dryops proposed by OLMI (1972) D. kaszabi may be Fig. 2. Dryops kaszabi sp. n. 9 : above, ovipositor, vagina, ductus spermatecae, sperma­thecaand spermathecal gland all in lateral view; below, detail of vagina in ventral views.
