New species and host plants of Anastrepha (Diptera: Tephritidae) primarily from Suriname and Par, Brazil.

Seventeen new species of Anastrepha, primarily from Suriname, French Guiana and Par, Brazil, are described and illustrated: A. aithogaster Norrbom from Brazil (Par), French Guiana, and Suriname; A. aliesae Norrbom from Suriname; A. brownsbergiensis Norrbom from Suriname; A. crassaculeus Norrbom Rodriguez Clavijo from Colombia (Magdalena, Norte de Santander) and Suriname; A. curvivenis Norrbom from Brazil (Amazonas), Ecuador (Zamora-Chinchipe), Peru (San Martn), and Suriname; A. fuscoalata Norrbom from Brazil (Par), French Guiana, and Suriname; A. gangadini Norrbom from Suriname; A. juxtalanceola Norrbom from Brazil (Par) and Suriname; A. microstrepha Norrbom from Brazil (Bahia) and Suriname; A. mitaraka Norrbom from French Guiana; A. neptis Norrbom from Brazil (Par), Ecuador (Orellana), Peru (Loreto) and Suriname; A. sobrina Norrbom from Brazil (Par), French Guiana, and Suriname; A. surinamensis Norrbom from Suriname; A. tenebrosa Norrbom from Brazil (Par) and Peru (Loreto); A. triangularis Norrbom from Suriname; A. wachiperi Norrbom from French Guiana and Peru (Cusco); and A. wittiensis Norrbom from Suriname. The following host plant records are reported: A. aithogaster from fruit of Parahancornia fasciculata (Poir.) Benoist (Apocynaceae); A. aliesae from fruit of Passiflora coccinea Aubl. and P. glandulosa Cav. (Passifloraceae); A. crassaculeus from fruit of an undetermined species of Pouteria (Sapotaceae); A. fuscoalata from fruit of Trymatococcus oligandrus (Benoist) Lanj. (Moraceae); A. sobrina from fruit of Eugenia lambertiana DC. (Myrtaceae); and A. wittiensis from fruit of Manilkara bidentata (A. DC.) A. Chev. (Sapotaceae).

Two new species of Anastrepha (Diptera: Tephritidae) from Ecuador.

Despite the fact that many species are economically important agricultural pests, the fruit fly fauna of Ecuador is still relatively poorly known. To better understand this fauna and the distribution and host plants of the pest species, the Proyecto Nacional de Manejo de las Moscas de la Fruta of AGROCALIDAD has conducted trapping surveys in many parts of the country. Two new species of Anastrepha from Ecuador that were collected by this project are described and illustrated: A. quadripuncta Troya Norrbom and A. tinctobasis Troya Norrbom. A new species group, the morvasi group, is recognized for A. morvasi Zucchi and A. quadripuncta.
