New Sawfly Species in the Hungarian Fauna (Hymenoptera, Symphyta), I V .

by L . Z O M B O R I , Budapest

Abstract — Twelve sawfly species new to the Hungarian fauna are given in brief, of which two are new to science: Fenella arenariae sp. n . and Fenella catenata sp. n. Three species are re-esta­blished : Calameuta punctata(KhVG, 1893), Cephas notât as K O K U J E V , 1910 and Dolerus quadrinotatus B I R O , 1884. A key to the females of the thoracicus-group o f species in European Dolerus JUR. is also presented. W i t h 3 figures.

Cephas variabilis M O C S Á R Y , 1886 par t im Cephas pravei D O V N A R - Z A P O L S K I J , 1926 syn. n .

This species is very closely related to C. haemorrhoidalis ( F A B R I C I U S , 1781) especially as far as the coloration o f the body is concerned. BENSON'S (1968) key to some species of the genus gives a very useful characteristic in the second couplet: " M a x i l l a r y palp wi th 5th segment much shorter than 6th (apical)" (Fig. 1); while in C . haemorrhoidalis these two joints are almost o f equal length (Fig . 2). Some additional features are listed below :

C. haemorrhoidalis

1. Frontal groove very narrow, at most only half diameter o f front ocellus, same wid th over entire length.

2. Mesoscutum wi th large, shining interspaces, medially wi th micropunctures laterally w i t h some larger punctures.

3. Abdomina l tergites 1-8 in 9 black, 5-7 might have tiny, yellow lateral flecks; in çf at most 5-6 wi th a broad, yellow band.

4. Antenna! joints below in $ from 14-15 on­wards at most b rown; in çf from 10 on­wards yellowish brown.

C. punctata

1. Frontal groove very broad, at least as wide as diameter o f front ocellus, somewhat nar­rowing towards antennae.

2. Mesoscutum entirely mat, two kinds of punc­tures, background wi th very dense micro-punctures strewn w i t h some large punctures.

3. Abdominal tergites 1-8 in $ black, 4-8 may be marked medially/dorsally with yel low; in çf at least 4-6 wi th a broad, yellow band.

4. An tenná i joints below in Q f rom 9-10 on­wards orange yellow; i n çf from 6 onwards orange yellow.

Adults have been netted f rom Matricaria chamomilla in Galatello-Quercetum roboris association, also in Peucedano-Galatelletum association.

R e m a r k s . — The re-establishment of this specific name seems justified, since the original description given by K L U G (1803, p. 56) best fits the taxon concerned. Some may argue why not one of the other two names: floralis (p. 53) and analis (p. 54) was chosen. The answer is that because the description of the latter two rather corresponds to the one given by F A B R I C I U S for C. haemor­rhoidalis, accordingly, they are considered as synonyms of the latter name. C. punctata on the other hand, has a copiously punctate mescocutum strewn wi th some larger punctures.

For a long time Cephas variabilis M O C S Á R Y , 1886, was regarded as a synonym o f " C haemor­rhoidalis var•. punctata K L U G " . The examination o f the type-series showed that some specimens (ex Herkules fürdő 1 9 ; N a g y v á r a d 2 ") are in fact synonymous wi th C. haemorrhoidalis, while the other type-specimens (ex N a g y v á r a d 1 9 > Herku les fürdő 1 -f ', Tasnád 1 çf ; Sátoral jaújhely 1 çf; T a s n á d -Szán tó 1 9 ) that o f C. punctata. This finding is partly supported also by MOCSÁRY'S (1886, p. 115) original observation when he compared the females o f C. variabilis to C. analis, and the males to C . pallipes. Apparently he himself was in doubt concerning the homogeneity of his type-series.

I suggest C. pravei as a synonym of punctata on the basis o f BENSON'S key, quoted above, and the statement of K L U G : "pa lp i anteriores . . . quinto brevissimo".

The final solution o f this nomenclatorial problem would need the examination o f the holo- or lectotype specimens o f the fol lowing specific or variety names: Tenthredo haemorrhoidalis F A B R I C I U S , 1781; Astatus analis K L U G , 1803; Astatus floralis K L U G , 1803; Astatus punctatus K L U G , 1803; Cephus atripes STEPHENS, 1835; Cephus quadriguttatus A . COSTA, 1882; Cephus variabilis M O C S Á R Y , 1886; Cephus haemorrhoidalis var. signifer K O N O W , 1896; Cephus pravei D O V N A R - Z A P O L S K I J , 1926. ( H N H M ) .

2. Cephus notatus K O K U J E V , 1910, sp. rev. — BENSON (1968) suggested the synonymy of this species wi th C. pygmaeus (L . ) . I n a work on the Hungarian fauna ( M Ó C Z Á R & Z O M B O R I 1973) I accep­ted his opinion due to lack of comparative material. But since in H o r t o b á g y (Újszentmargi ta , 1974. V . 7-10, leg. DRASKOVITS) a female specimen was collected which much resembled the description of the above species, I compared the two taxa. Besides the colour, since BENSON said it was only a melanic form of pygmaeus, and other minor differences, I found two important features which de­finitely show that the two species are distinct.

I n the female o f C. notatus all an tenná i joints are longer than wide, hind basitarsus long and slender, equalling combined lengths o f 2nd and 3rd tarsal joints (ratio as 28 : 29). N o male specimen was available.

In the females o f C . pygmaeus 12-14th joints quadrate, al l subsequent joints, f rom 15th onward wider than long. I n the males antennae were more slender, st i l l at least one or two joints quadrate or wider than long. H i n d basitarsus shorter than combined lengths o f 2nd and 3rd tarsal joints (ratio as 30 : 36). ( H N H M ) .

3. Cephus runcator K N O W , 1896 — This species much resembles the common C. pygmaeus (L . ) but its wings are heavily infuscated, the hind tibiae are yellow, only around the apex black, pro-and mesonotum mat w i th very dense microsculpture, and only penultimate jo in t o f antenna wider than long.

4. Dolerus quadrinotatus BÍRÓ, 1884, sp. rev. — This species was described on the basis o f two female specimens by the great Hungarian collector LAJOS BÍRÓ. A few years later K O N O W (1891) treat­ed the taxon only as a variety o f D. thoracicus F A L L . (p. 215). Ever since subsequent authors accept­ed this ranking, obviously, no one has taken the trouble to look at the type-specimens concerned.

Since 1 am critically working myself through the sawfly material of the Hungarian museums, in Budapest, I carefully studied the type. I say type and not types, since there is only one type-specimen left in the collection, which was designated as "Lectotypus Ç Dolerus quadrinotatus B Í R Ó , 1884 des. Z O M B O R I , 1977". The other type-specimen, i t is most likely, is w i th D R . W . H E L L É N (Helsinki) who identified in the 1950s long series of sawflies from the Hungarian Natural History Museum, Budapest.

Besides the type from T a s n á d (today Tasnad, Transylvania, Roumania), several other specimens are known from a number o f localities: Szőllőske (today Seleska, Czechoslovakia), N é m e t Bogsán (today Bocsa Vasiovei, Roumania), Borosjenő (today Ineu, Roumania) and Simontornya (Hungary). As far as I am aware this species has not been recorded outside of the Carpathian Basin. The flight period of the 21 available specimens, all females, is between the 25th of March and the 14th o f A p r i l , apparently an early species even among the representatives of the genus Dolerus.

B I R O compared his D. quadrinotatus to D. vulneratus M O C S Á R Y , 1878, described from Siberia, but BIRO'S species clearly differs f rom it in several characteristics.

I n order to find its place in the system of Dolerus the re-established quadrinotatus is included in a key for the species-group of thoracicus. This group of species belongs to BENSON'S (1952) so-called black-group of Dolerus w i th evenly punctured mesopleuron, black abdomen, 1st and 2nd abdominal tergites "always wi th some transverse surface sculpture", etc. This particular group may be sepa­rated f rom the rest of the black-group by their thorax being at least partly orange yellow (except the melanic race of sanguinicollis K L . ) and their entirely black legs at least as far as the females are concerned.

Front ocellus recieved in a semicircular depression. Triangular area below frons excavated, inverted gut t i form in shape, lowermost part surrounded by a blunt elevation, bottom of this basin without distinct deep furrow, uppermost part o f basin broken through towards front ocellus, thus, strongly elevated frons channelled connecting semicircular depression and triangular area.

6. Fenella catenata sp. n .

9 . — Black. H e a d black, only palpi b rown and mandibles reddish brown. Clypeus entire, malar space about half diameter o f front ocellus. Antenna dark brown wi th semi-erect fuscous hairs; 3rd a n t e n n á i j o in t much longer than 4th (ratio as 1.6 : 1). F ron t ocellus quite free-standing, frons ele­vated, triangular area below frons evenly convex w i t h a shallow median depression, lowermost part surrounded by a blunt ridge ; median depression broadening towards front ocellus, thus rather cigar-shaped. Surface shining, without distinct sculpture. Postocellar groove continuing i n front as a shal­low furrow only, thus, frons not appearing as much elevated. P O L < O O L . — T h o r a x black wi th weak alutaceous surface sculpture on lateral lobes o f mesonotum. — W i n g s brownish i n -fuscate, vein M strongly bent at basal one-quarter, appearing almost angular, then almost entirely straight. — - L e g s black, only apical quarter o f femur, tibia and tarsus light brownish yellow. H i n d basitarsus longer than fol lowing two joints together. — A b d o m e n black, shining wi th hardly visible surface sculpture. Lateral setae of sawsheath straight, short, enclosing about 45° w i t h side of sawsheath. — Le n g t h : 3 m m ; alar expanse : 7 m m . — çf and host plant unknown.

The holotype and the two paratypes are deposited in the Hungarian Natura l History Museum, Budapest.

The new species belongs to the nigrita-group o f species. I t m a y , however , at once be separated f r o m the other congeners o f this species-group by the pecul iar cigar-shaped depression i n the t r i angu la r area be low the frons. Th i s feature d i s tan t ly resembles that one o f E. excavata Z O M B O R I , 1978 since the depression is in tac t a l l r o u n d , i t does n o t open i n any d i r ec t ion , b u t the shape i n excavata is large and p h y l l i f o r m .

7. Fenella nigrita W E S T W O O D , 1840 — Apparently, this is the commonest species of the genus Fenella i n Europe, since most faunal lists make reference to this name. I t is a small mining sawfly de­veloping in Agrimonia eupatoria, Potentilla reptans.

8. Metallus albipes ( C A M E R O N , 1875) — This is again a small, black, mining sawfly species, larvae feeding in the leaves o f Rubus idaeus and R.fruticosus. BENSON (1952) made reference to this species as being a local pest in some counties o f England. I t is very unlikely that the species is as common as that in Hungary, since so far only one specimen has been collected: Tihany, Csúcshegy, 1967. V I . 22, leg. M Ó C Z Á R , 1 Q .

BENSON said legs are entirely white, the Hungarian specimen has all its coxae and about basal half o f fore and mid femora light brown. ( H N H M ) .

9. Profenusa thomsoni ( K O N O W , 1886) — There is only one specimen o f this small, though ro­bust, leaf-mining species f rom Csesznek, 1976. V I I I . 20, leg. Z O M B O R I , 1 9 •

BENSON (1952) wrote that "abdominal tergites smooth" i n fact, under higher magnification it has a weak alutaceous surface sculpture. Furthermore, mesopleuron w i t h sparse pubescence, while meso-sternum not entirely smooth but wi th a very few scattered hairs. First cubital cross-vein quite clearly indicated, but this feature is also present in some specimens o f P. pygmaea K L . A n a l cell of h ind wing closed (not open), as is the case in most specimens o f P. pygmaea. But there are some specimens o f the latter species in which the apex of the anal cell is partly faded or partly broken, i.e. the vein is discon­tinuous. A very good differentiating characteristic o f P. thomsoni is the darkly infumated basal two-thirds of fore wing while the apical th i rd is very light. ( H N H M ) .

10. Scolioneura betuleti ( K L U G , 1814) — This is the first occasion that this species is recorded f rom Hungary. The larvae are mining in various species o f Betula. Larvae were collected f rom Betula pubescens at Nagykovács i , on the the 30th o f May , 1976 and kept in jars where they continued to feed i n the mines for a few more days. Then they emerged from the mine and entered the soil for pupation. On the 23rd o f A p r i l , 1977 four females and three males, and on the 26th o f the same month two more females emerged. According to my rearing the species has only one generation and not two as reported elsewhere i n various papers. ( H N H M ) .

11. Sterigmos ventralis (PANZER, 1799) — This very interesting species was recently revised along wi th its European relatives ( Z O M B O R I 1977).

One small-sized (5.5 mm) female specimen was found mixed up wi th the representatives o f Mo-nophadnus spinolae K L . (det. H E L L É N ) . The Hungarian locality is "P i l i s -Maró t C S Í K I " . ( H N H M ) .

12. Stethomostus funereus ( K L U G , 1814) — I t is a rather elusive species, rarely collected. The first Hungarian locality is at " T á k o s Bockereki e. ( rdő) 1966. V I . 8, leg. S Ó L Y M O S N É " 1 ( H N H M ) .
