Abraxini and Semiothisini Species from Mongolia (Lepidoptera, Geometridae : Ennominae)*

Abstract — Eleven species of the tribes Abrax in i and Semiothisini are shown from Mongolia; Tephrina kaszabi sp. n. , and Tephrina arenacearia mongolica ssp. n . are described. — 2 figures.

Eleven species of the tribes Abraxin i and Semiothisini have been found i n Dr . Z. K A S Z A B ' S collections f rom Mongolia. The number of specimens, w i t h special regard to some species inhabiting sztyeps, is occasionally significantly high, permit t ing the clarifi­cation of some subspecific problems and the description of new taxa.

The size o f the subspecies described f rom the dshungarian A l a - T a u and the Sayan Range is ha rd ly smaller t h a n t h a t o f the nominate subspecies, indeed, the females are occasionally o f equal dimensions. However , some features o f the colo­r a t i on and p a t t e r n are essentially d i f ferent : the ye l low is no t v i v i d b u t pale and f l a t , the black pa t t e rn reduced, the composite p ic ture o f the w i n g thus ra the r washed-out.

On the forewings o f the imagos representing the subspecies ranging p r i n c i p a l l y i n the A m u r and Ussuri areas, as wel l as i n China and Japan, the median str ipe is usual ly broken in to three sections. This feature holds for on ly one specimen collec­ted b y K A S Z A B i n Mongol ia , whi le i n the other exemplars the str ipe is s t rong ly constr ic ted.

The species, ranging f rom West Europe to the Fa r East, was h i the r to un ­k n o w n f rom Mongol ia . The single specimen available is insufficient to c lar i fy sub-specific problems, bu t , on the basis o f mater ia l collected i n the area o f the species, S. artesiaria is apparent ly not inc l ined to fo rm geographical races.

I t s m a i n feature against the nominate subspecies is the near ly or ac tua l ly meet ing t h i r d and f o u r t h transverse stripes o f the forewing, the second and f o u r t h transverse stripes being usual ly broader t h a n the f i rs t and the t h i r d ones, and the basal f ie ld showing a brownish suffusion.

6. Semiothisa saburraria kenteata S T A U D I N G E R

D t . ent Z. I r is , 1896, 9 : 273.

I n view of the confusion and uncertainties concerning the separation of the diverse fo r i us, I t h ink i t justified to submit a detailed description of the subspecies on the basis of the unparalleled series now available from Mongolia.

The subspecies i n question was cited by S T A U D I N G E R in 1896 (loc. cit.) as "Macaria Intermaculata S T G R . var. Kenteata S T G R . " This statement preceded the publication of the actual description of "Intermaculata S T G R . " (D. ent. Z. I r is , 1897, 10:41), but, in any case, the specific name given by S T A U D I N G E R is a junior subjective synonym (saburraria E V E R S M A N N , 1881 = intermaculata S T A U D I N G E R , 1897). Incidentally, S T A U D I N G E R h im­self wrote about saburraria Ev . (D. ent. Z. Ir is , 1897, 10:65), but relegated i t to the genus Thamnonoma, remarking, however, that the species is unkown to h im ("Mir ist diese von E V E R S M A N N nach Stücken von I rkutsk beschriebene A r t in natura unbekannt.. .").

A r t e n erkennen läßt — zu einer dissymmetrischen S t r u k t u r führt, die 1. du rch die Spezialisation bzw. R e d u k t i o n der Harpen , 2. durch die Verlängerung der „Exten­sion o f sacculus" auf einer Seite oder beiderseits, 3. durch die K o m b i n a t i o n beider Vorgänge zustande k o m m e n kann . B e i einigen Gat tungen ist f re i l i ch auch eine Redukt ionstendenz vorhanden, die sich du rch eine Abschwächung der Sklerotisa-t i o n der Harpen , durch den Schwund des Sacculusfortsatzes bzw. i n einzelnen Fäl­len auch du rch die R e d u k t i o n des Cucullus bzw. der Corona erkennen läßt. U n t e r jenen Gat tungen, die hier an dem Anfang des Systems der Hadeninen gestellt s ind u n d zweifellos zu einer monophylet ischen Gruppe v o n nächster Verwandschaft gehören, ist diese ursprüngliche, noch z ieml ich genau symmetrische S t r u k t u r vor­handen: so i n den Genera Cardiestra u n d Aglossestra, die du rch wenige, geographisch z iemlich streng isolierte allopatrische A r t e n i m paläarktischen E r e m i a l ver t re ten sind. A u c h die Genera Saragossa, die schon eine gewisse Redukt ionstendenz auf­weist bzw. Gardepia, die du rch eine spezialisierte dissymmetrische Ausb i ldung des Sacculusfortsatzes gekennzeichnet ist ( B O U R S I N " verwechselt diesen spezialisierten Sacculusfortsatz m i t der Harpe! — v g l . Zschr. Wiener E n t . Ges. 4 7 : 160), s ind — als i m Raupens tad ium au f H a l o p h y t e n lebende Tiere — einerseits auch zu eremialen Bio topen , andererseits aber an mar i t ime , halophile Pflanzengemein­schaften gebunden.

Die i m Grundp lan der Gen i t a l a rmatur der G a t t u n g Cardiestra noch ziemlich nahestehenden Genera Thargelia (vg l . Th. distincta C H R I S T , u n d fissilis C H R I S T .

bzw. Th. arenicola S C H T S C H B T K I N ) bzw. Odontelia, die aber wie i n den äußeren morphologischen Merkmalen (Flügelform- bzw. Muster , klauenförmige T ib i en -fortsätze, Fühlerstruktur) als auch i n der Geni ta lmorphologie (eine ausgeprägte Tendenz zur Dissymmetr ie bei mehreren Thargelia-Arten, durch eine dissymmet-rische plattenförmige Ausb i ldung der Harpen , die auch du rch eine entsprechende U m b i l d u n g der Va lven fo rm m i t verlängerter „Extension o f sacculus" begleitet is t , v g l . S U K H A R E V A 1972) eine ganze Reihe v o n Spezialisationen aufweisen, gelten auch als Eremia l fo rmen der zentralasiatischen-turanischen Ausbrei tungszentren. Die Ga t tung Thargelia läßt sich sonst — aufgrund ihrer Gen i t a l s t ruk tu r v o n Ha-dula n u r z iemlich schwer u n d sub jek t iv trennen, obwohl die E x t r e m f o r m e n beider Genera — besonders hab i tue l l — ziemlich wei t voneinander entfernt s ind.* D ie artenreiche G a t t u n g Hadula zeigt z. T . ähnliche Spezialisation i n der Geni ta l s t ruk­tu r , wie Thargelia: eine Verlängerung der "Ex tens ion o f sacculus", die oft nach außen gebogen, zugespitzt oder sogar am Ende fein sägezähnig ist (offenbar m i t einer „Harpen-Funktion" bei der Paarung), aber ohne einer dissymmetrischen plattenförmiger Ausb i ldung der rechten Harpe , die bei E x t r e m f o r m e n einiger Thargelia-Arten vorhanden ist . A u c h i n der anderen, und m i t Hadula offensicht­l i ch i n sehr enger Verwandschaft stehenden, artenreichen G a t t u n g Discestra läßt sich eine m i t hochgradiger Spezialisation verbundene Formenmannigfa l t igke i t beobachten, besonders i n der „Extension o f sacculus", die bei einigen A r t e n (hoplites S T G R . , mendica S T G R . , mendax S T G R . , loeffleri R E I S S E R ) beiderseits lang ausgezogen ist u n d eine ähnliche F o r m besitzt, wie jener For tsa tz gewisser Hadula-Artein, während die A r t e n der dianihi T A U S C H . - , armata S T G R . - , furca E v . - Gruppe eine, i n dieser H ins i ch t stark dissymmetrische A r m a t u r haben. A n dieser Stelle sei be­merk t , daß die G a t t u n g Discestra. aufgrund der A u s b i l d u n g des Sacculusfortsatzes auch m i t Gardepia i n Verwandtschaf t zu stehen scheint.
