Eustiromastix falcatus Galiano 1981

Figs. 1-5

Material examined: Brazil, Pará , Monte Alegre, 16 Jun 2001, 1♂ (no collector, MPEG 4944 ) .

Diagnosis: Male (length 7.3 mm). The specimen has the characteristic coloration described for the species, with legs light brown with darker rings and patches ( Figs. 4-5 ). Moreover, this resembles E. bahiensis and E. macropalpus but differs from them in having the palp with a shorter embolus and a flattened tibial apophysys, wider than long, and a long and curved cymbium ( Figs. 1-3 ) ( Galiano 1981).

Distribution: Trinidad (Port of Spain), French Guiana (Saint-Élie, National Natural Reserve La Trinité) and Brazil (Pará). Eustiromastix falcatus to date has only been found in northern Brazil. However, this species might be present throughout other Amazonian locations of northern Brazil or may be in southern Venezuela, Guyana or Suriname.

Comments: This is the second published record of this species since the original description (see Galiano 1981), and the second location other than its type locality.
