Lectotype designation. Brèthes (1916: 141) described Sarcophaga argentina from several specimens, but the author did not mention the number of specimens or their sex. Indeed Brèthes only provided information on date and collector of these specimens: “ En febrero del corriente año, el doctor Pedro Caride Massini trájome varios ejemplares de una mosca...” ( Brethes 1916: 141). We have located ten presumed syntypes (four males, five females, and one specimen of unidentified sex) from Buenos Aires in MACN, whose identity, date, and collector match the original description. One male syntype is hereby designated lectotype of Sarcophaga argentina Brèthes, 1916 in the interests of nomenclatural stability. Lectotype male (MACN): in good condition, pinned. Labels: “B. Aires / II,1916 / Dr. Caride [white label, handwritten] // 11575 [white label, red square, handwritten] // Bs. Aires [green label, black square, printed] Sarcophaga / argentina Br. [white label, handwritten]”. Paralectypes 3 ɗ, 4 Ψand one damaged (sex not recognizable) (MACN): pinned. Labels: “B. Aires / II, 1916 / Dr. Caride [white label, handwritten] // Sarcophaga / argentina Br. [white label, handwritten]”. Paralectotype 1 Ψ(MACN): pinned. Labels: “ Sarcophaga / argentina Brethes / Bs Aires II-1916 / Dr. Caride / Type o Cotype !! [white label, handwritten]”.

Other material studied: Buenos Aires: 3 ɗ, 2 Ψ Ciud. Aut. Buenos Aires, II.1944 on rotten meat ( ANLIS); 4 ɗ, 2 Ψ Ciud. Aut. Buenos Aires, XI.1996 meat bait, Oliva leg. ( MACN); 29 ɗ, 7 Ψ Ciud. Aut. Buenos Aires, and X.1997 reared from meat, Mariluis leg. ( ANLIS); 10 ɗ, 7 Ψ Moreno, Moreno, 12.I.1949 ( ANLIS); 2 Ψ Olivos, Vicente Lopez, IX.1951 ( ANLIS); 18 ɗ, 16 Ψ Mercedes, Mercedes, I.2004 ( ANLIS); 1 Ψ San Bernardo, De la Costa, 7.IV.2007, Mulieri leg. ( ANLIS).

Remarks: Brèthes (1916) provided schematic drawings of the male terminalia. In addition, Blanchard (1942a) presented good illustrations of male terminalia, while the female was described but not illustrated.

Biology: This cosmopolitan species is regarded as highly synanthropic ( Povolny & Znojil 1989). Obtained from dead or dying insects ( Lahille 1907), and from dead vertebrates ( Oliva 1997; Romera et al. 2003). In the present work, this species was captured and reared from rotten meat. Sarcophaga (L.) argyrostoma has public health and veterinary significance. There are some records of it causing myiasis in sheep ( Zumpt 1965) and man ( James 1947; Burgess & Spraggs 1992). In Argentina , Mazza & Basso (1939) reported S. (L.) argyrostoma as causing cutaneous myiasis. Oliva (1997) reported it as a forensic indicator.
