Description of Pintomyia (Pifanomyia) paleotrichia, a Miocene period new species from the Dominican Republic (Diptera: Psychodidae: Phlebotominae)

Abstract

A new fossil species of phlebotomine sandflies is described from Dominican amber based in one specimen. Pintomyia (Pifanomyia) paleotrichia sp. nov. is distinguished from the other extant and extinct species by aspects of paramere and the basal tuft of bristles in the gonocoxite.

Description of a new species, Pintomyia dissimilis nov. sp., a phlebotomine fossil from Dominican Republic amber (Diptera: Psychodidae: Phlebotominae)

“…Of 14 male fossil species described, 10 belong to the genus Pintomyia [ 5 ]. Pintomyia paleopestis (Peñalver & Grimaldi, 2005) and Pintomyia brazilorum Andrade Filho, Galati & Falcão, 2006 present only two developed spines in the gonostyle [ 7 , 8 ] while in Pintomyia falcaorum Brazil & Andrade Filho, 2002, Pintomyia killickorum (Andrade Filho, Falcão, and Brazil, 2004) Pintomyia filipalpis (Peñalver & Grimaldi, 2005), Pintomyia paleotownsedi Andrade Filho, Falcão, Galati, and Brazil, 2006, Pintomyia paleotrichia Andrade Filho, Brazil, Falcão, and Galati, 2007, and Pintomyia dominicana Andrade Filho, Galati & Brazil, 2009 this structure has four spines [ 5 , 7 , 9 - 12 ]…”

Lutzomyia adiketis sp. n. (Diptera: Phlebotomidae), a vector of Paleoleishmania neotropicum sp. n. (Kinetoplastida: Trypanosomatidae) in Dominican amber

“…Four different configurations of the Sc vein exist in sand flies [ 9 ]. The Sc vein can be free, with the distal end not connected to either the costa or R1, as occurs in the Dominican amber Pintomyia paleotownsendi Andrade Filho et al [ 10 ] and Pintomyia falcaorum Brazil et al [ 11 ], Sc can meet the costa vein, as in the Dominican amber P. paleotrichia Andrade Filho et al [ 12 ] or the Sc can meet R 1 , as in the Dominican amber Pintomyia brazilorum Andrade Filho et al [ 13 ], P. killickorum Andrade Filho et al [ 14 ] and all five species described by Peñalver & Grimaldi [ 15 ]. The fourth condition, where Sc forks distally, uniquely occurs only on L. adiketis , among the described Dominican amber fossils.…”

Review of American Fossil Phlebotominae (Diptera: Psychodidae) With a Description of Two New Species

“…The terminalia of this species overlap, impeding visualization of all the bristles of the gonocoxite and their point of implantation (Andrade Filho et al 2007), although Ϸ13 bristles can be seen. The apical spine of the gonostyle of this species is highly developed, as that found on the present-day species Pintomyia spinacrassa (Morales, Osorno-Mesa, Osorno, and Hoyos, 1969), both being easily distinguished (among other characters) by the paramere of the fossil species, which presents a group of setae on its apex.…”
