Strebla guajiro ( García & Casal, 1965)

Euctenodes guajiro García & Casal, 1965: 14 , figs. 10-16. Strebla guajiro: Wenzel, 1976: 151 .

Material examined: Misiones: Parque Provincial Teyú Cuaré, 27°17′S, 55°35′W, 10.x.2009, 1 ♂ ( CMLA 748) on Carollia perspicillata ♀ ( FMI 139).

Identification: The genus Strebla contains 26 species ( Dick & Graciolli, 2018) but the one treated in this study differs from all the others as the frontoclypeus have a pair

of detached plates or an unsclerotized median suture; the second anterior pigmented mesonotal suture is usually distinct; the tibia III has only two or three distal setae on the dorsal surface that are longer than the others; the preceding setae are less than twice long as the other tibial setae; the prescutum has only two irregular transverse rows of setae laterally between the transverse mesonotal suture and the anterior suture; the postvertex has eight strong macrosetae arising from the posterior margin on each side; the thoracic setae is anterior to the mesonotal suture sparse; and the male genitalia have postgonites at a curved angle (Wenzel et al., 1966; Graciolli & Carvalho, 2001).

Comments: The main host for this species is C. perspicillata ; however, there are also records for other species of Phyllostomidae , and species of other families such as Mormoopidae , Natalidae and Vespertilionidae . In Argentina, it was only found parasitizing Carollia perspicillata from Misiones (San Ignacio Department) (Autino et al., 2018). As in all species of this genus, their legs are short and thick and the hind legs are slightly longer than forelegs.
