Anodocheilus guatemalensis (Zaitzev, 1910)

STUDIED MATERIAL. STANN CREEK: Cockscomb Basin Wildlife Sanctuary , pool with leaf litter next to stream, 16°46'49,3"N, 88°28'7,1"W, 06.V.2015, Leg. K. Scheers & A. Thomaes (7 ex.) ; Cockscomb Basin Wildlife Sanctuary, Wari Lagoon , 16°46'46,1"N, 88°28'2,4"W, 07.V.2015, Leg. K. Scheers & A. Thomaes (25 ex.) ; TOLEDO: Bladen Nature Reserve , pond transition savannah-forest, 16°32'26,3"N, 88°42'57,1"W, 20.IV.2015, Leg. K. Scheers & A. Thomaes (2 ex.) .

DISTRIBUTION. Belize (first record), Costa Rica, Guatemala, Panama ( YOUNG, 1974). In Belize this species seems uncommon and was encountered at two sites in the Stann Creek district and one site in the Toledo district ( Fig. 2 B ).

HABITAT. We found this species at only three sites, but all sites had at least locally a layer of leaf litter on the bottom and were partly shaded. It seems that, in contrast to A. francescae , this species does not favor warm, sun exposed silt ponds but is more typically found in less exposed ponds, oxbows etc. ( Fig. 4 ).
