Toad bugs (Hemiptera: Gelastocoridae) in Myanmar amber

Two new species of toad bugs (Nerthra bichelata sp. n. and Gelastocoris curiosus sp. n.) (Hemiptera: Gelastocoridae) are described from Myanmar amber. Diagnostic characters of N. bichelata sp. n. are the large paired ocelli, subequal claws on protarsus that is fused with the protibia, slender profemur bearing two short, prominent ventral teeth, a large spherical terminal antennal segment and an elongate terminal segment of the rostrum. Diagnostic characters for G. curiosus sp. n. are paired, equal claws on the single-segmented, articulated protarsus, lateral margin of pronotum with a triangular protrusion and relatively narrow profemora with a series of broad transverse thickenings on the apical half of the ventral surface. These are the first descriptions of Gelastocoridae in amber and the first record of Gelastocorinae in Asia.
