Ibáñez-Bernal, Sergio, Muñoz, José, Rebollar-Téllez, Eduardo A., Pech-May, Agelica & Marina, Carlos F., 2015, Phlebotomine sand flies (Diptera: Psychodidae) of Chiapas collected near the Guatemala border, with additions to the fauna of Mexico and a new subgenus name, Zootaxa 3994 (2), pp. 151-186 : 175-176

Psathyromyia (Xiphopsathyromyia) Ibáñez-Bernal & Marina , nomen novum

Lutzomyia species group Dreisbachi : Lewis et al., 1977: 325; Martins et al., 1978: 152 (list); Young & Duncan, 1994: 411 (references, taxonomy, and distribution).

Lutzomyia (Xiphomyia) Artemiev, 1991: 73 . Type species: Psathyromyia aclydifera (Fairchild & Hertig) (by original designation), not Xiphomyia Townsend, 1917 (Tachinidae) . Additional references: Galati, 1995, 137; Galati 2003, 42 (list, keys).

Young & Duncan (1994) were the first to note that the name Xiphomyia was preoccupied for a genus of Tachinidae (Diptera) . Nevertheless, as they did not recognized the taxon in the sense of Artemiev (1991) they continued using the species group Dreisbachi and consequentially did nothing with the homonym. Later, Galati (1995) and Galati (2003) used Xiphomyia for this group without acknowledging the homonymy. In order to make it possible to apply the phylogenetic classification of Galati in general, it is necessary to propose a new name to replace the homonym.

Etymology. Xiphopsathyromyia, from Greek, xiphos, a Greek sword, and Psathyromyia , name of the genus to which this subgenus belongs. We preserve the prefix xiphos of Artemiev added to the complex name of the genus Psathyromyia , which is formed by psathyros, friable, and myia, fly. The idea of the new name is to help in relating this group of species to the original taxon nomination as well as denoting the actual position within the genus.

Diagnosis. Antennal flagellomeres 10 and 11 with sensory papillae; ascoids with long proximal spurs. Palpal segment 5 shorter than palpal segments 3 + 4; segment 2 without Newstead sensillae; ventro-cervical sensilla absent; tarsomere 1 of hindleg as long as or longer than 2+3+4+5. Male: gonostylus with 4 large spiniform setae inserted at different levels and no preapical fine seta; gonocoxite with 3 or 4 preapical recurved setae, but other persistent setae could be present as in Pa. aclydifera ; paramere variable, divided or not; lateral lobe with 7 to 10 large dorsal setae at or near its distal end; ejaculatory filaments shortest than 2.0 times the length of apodeme + sperm pump. Female: cibarium with 10 or more horizontal teeth, numerous vertical teeth, a broad pigment patch, and complete arch; pharynx unarmed; spermathecae strongly annulated, sometimes imbricated, the terminal knob large, symmetrical or asymmetrical; individual spermathecal ducts relatively thin, longer than common spermathecal duct (Young & Duncan 1994; Galati 2003).

Type species. Psathyromyia (Xiphopsathyromyia) dreisbachi (Causey & Damasceno, 1945) , originaly designated by Artemiev (1991).

Remarks. This subgenus is currently comprised of four valid species: Psathyromyia aclydifera (Fairchild & Hertig, 1952) , Pa. dreisbachi (Causey & Damasceno, 1945) , Pa. hermanlenti (Martins, Silva & Falcão, 1970) and Pa. ruparupa (Martins, Llanos & Silva, 1976) . Only one species has been recorded in Mexico.
