ALVES-PIRES C.*, RAMOS H.C.**, RIBEIRO H.* & EASTON E.R.***

Summary:

The presence of phlebotomine sandflies (Sergentomyia barraudi) in Macau, a Territory in Southern China under Portuguese

administration, is here recorded for the first time.

Nineteen specimens (14 males and 5 females) were examined for the most important features which were shown to agree with known descriptions of the species.

KEY WORDS : phlebotomine sandflies, Sergenlomyia barraudi, Macau, distribution.

résumé : PRÉSENCE DE SERGENTOMYIA BARRAUDI (SINTON, 1929) A MACAO

Les auteurs signalent pour la première fois la présence des phlébotomes à Macao, Territoire du Sud de la Chine sous administration portugaise.

Dix-neuf adultes (14 mâles et 5 femelles) ont été capturés dans une grotte artificielle en septembre 1994. Les caractères observés sont conformes à la description de l'espèce Sergentomyia

barraudi (Sinton, 1929).

MOTS CLÉS : phlébotomes, Sergentomyia barraudi, Macao, distribution.

INTRODUCTION

SBARRAUDI was described by Sinton (1929) and p l a t e r redescribed by Raynal & Gaschen (1934, 1935), from adults caught in India and Vietnam, respectively.

This species has a wide distribution in the Oriental Region (Lewis, 1978).

In Macau, a Territory in Southern China presently under Portuguese administration, phlebotomine sand- flies have not yet been recorded, although S. BARRAUDI and S. INDICA are known in near by Hong Kong (Lewis, 1978; Leng & Zhang, 1993), while more than forty spe- cies are known in China (Leng & Zhang, 1993).

It is presumed that S. BARRAUDI is not responsible for the transmission of leishmaniases (Killick-Kendrick, 1990).

OCCURRENCE OF SERGENTOMYA (PARROTOMYA) BARRAUDI (SINTON, 1 9 2 9 ) IN MACAU

DISCUSSION AND CONCLUSION

F E M A L E S

T

h e p r e s e n c e o f an antennal s e g m e n t A3 longer than A4 + A5, a n d the value o f the ratio bet­

w e e n length a n d width o f the s p e r m a t h e c a e ( 2 . 7 ) w e r e o b s e r v e d b y S i n t o n ( 1 9 2 9 ) , R a y n a l &

G a s c h e n ( 1 9 3 4 ) a n d Cates & Lien ( 1 9 7 0 ) .

W e found about 6 0 cibarial teeth in o u r five females, a little m o r e ( 4 0 - 5 0 ) than o b s e r v e d b y Sinton (op. cit.), Raynal & G a s c h e n ( 1 9 3 4 ) and Parrot & Clastrier ( 1 9 5 2 ) , but similar to the values cited by Lewis ( 1 9 7 8 ) . T h e lamp-glass s h a p e d pharynx a n d a vein R l shorter than R2 + R3 in the wings, are similar to the observations o f Sinton ( 1 9 2 9 ) , Raynal & G a s c h e n ( 1 9 3 4 ) a n d Cates

& Lien ( 1 9 7 0 ) .

The bifid s h a p e o f the p i g m e n t e d patch o f cibarium in the females, characteristic o f this s p e c i e s (Sinton, 1 9 2 9 ) , w a s present in o u r five females.

M A L E S

The style with four apical spines, with length about four times the width, the h o o k e d paramere, and a ciba­

rium with about 16 teeth, as s e e n in o u r 14 males, are also characteristic o f Sergentomyia barraudi (Sinton, 1929; Raynal & G a s c h e n , 1 9 3 4 a n d Cates & Lien, 1 9 7 0 ) .
