Fig. 6B

Material studied.

Colombia • 67 specimens; Cundinamarca, pools by the road from Bogotá before Matarredonda park; 3,300 m alt.; 20.xi.2018; 4.564, -74.008; Ospina, Balke & Megna leg.; COL_MB_2018_09; UNAL, ZSM .

Notes.

This form is intermediate between two subspecies, in terms of body size and coloration (Fig. 6B ). Females are mostly completely microreticulation dorsally as in L. b. bogotensis , but in some the head and pronotum are shiny, and the elytra have microreticulation only apically. The metathoracic wings are large, as in L. b. bogotensis . Some specimens determined by body size and dorsal coloration would be assigned to L. b. matarredonda , but are fully winged (Fig. 6B ).

Measurements

(N = 20). Total length 2.2-2.5 mm (mean 2.36); length without head 1.9-2.2 mm (mean 2.02); maximum width 1.1-1.2 mm (mean 1.07).

Distribution.

Below Páramo de Matarredonda (Fig. 1 ).
