![]() ![]() ![]() Surface sculpture terminology follows Harris (1979), and wing veins are described according to Mason (1986). General morphological terminology follows Sharkey and Wharton (1997), except for the use of the term “precoxal sulcus”, which replaces “sternaulus” according to Wharton (2006). Photographs were taken and edited using a Leica® Z16 APO-A stereoscopic microscope, a Leica® DFC295/ DFC290 HD camera, and the Leica Application Suite® program. Materials and methodsĪll our studied specimens were collected during the past 3 years and are housed at the Colección Nacional de Insectos, Instituto de Biología, Universidad Nacional Autónoma de México, Mexico (CNIN), and the Museo Argentino de Ciencias Naturales “Bernardino Rivadavia”, Buenos Aires, Argentina (MACN). We also provide a key to these first described species of Allorhogas from Mexico and give information about the biology of one of these species, which was reared from leaf galls of a Polygonaceae plant species. Our aim is to describe 7 of these new species, which we also characterize molecularly with the mitochondrial DNA sequence fragment belonging to the barcoding locus. Recent collecting trips conducted in tropical dry forests in the states of Guerrero, Jalisco and Oaxaca allowed us to obtain a number of specimens of Allorhogas, all of which belong to undescribed species. All available information for this country only consists of scattered records of unidentified specimens assigned to Allorhogas from 9 different states: Guanajuato, Guerrero, Nuevo León, Oaxaca, Puebla, Quintana Roo, Sinaloa, Yucatan and Tamaulipas ( Delfín-González and León, 1997 Sánchez-García and López-Martínez, 2000 González-Hernández et al., 2003 Coronado-Blanco, 2011). To date, no Mexican specimens of Allorhogas have been identified at species level. ![]() Some species are known to induce galls, mainly in seed tissues of representatives of the plant families Fabaceae and Melastomataceae (Macedo et al., 1998 Chavarría et al., 2009 Centrella and Shaw, 2010), whereas others have been obtained from galls induced by other insects, although their interaction with these inducers is essentially unknown ( Gahan, 1912 Penteado-Dias and Carvalho, 2008). All Allorhogas species for which biological information is available are associated with plant galls. semitemporalis Fischer, 1960, was described from Iraq. ![]() Members of this group are mainly distributed in the Neotropical region, though 3 species were described from North America and a fourth one, A. Allorhogas is a moderately diverse doryctine wasp genus with 35 currently described and a large number of undescribed species ( Marsh, 2002 Yu et al., 2005 Martínez et al., 2008, 2011 Penteado-Dias and Carvalho, 2008 Chavarría et al., 2009 Centrella and Shaw, 2010). ![]()
