Bidessodes elongatus (Sharp, 1882)

( Fig. 1 B )

STUDIED MATERIAL. TOLEDO: Punta Gorda , temp. stream in forest, 16°06'37,6"N, 88°49'18,8"W, 25.IV.2015, Leg. K. Scheers & A. Thomaes (1 ex.) .

DISTRIBUTION. Belize (first record), Costa Rica, Guatemala ( MILLER, 2017). In Belize this species was only recorded from a single site in the Toledo district ( Fig. 2 C ).

HABITAT. Habitat preference of this species is yet unknown. We found only one single specimen among leaf litter in a shaded, slow flowing stream in the forest.

NOTE. We have only one female specimen and thus identification is based on external features only. B. elongatus is the only species of the genus present in Central America .
