Material examined. 1♁ HONDURAS, Comayagua, 16 km SW of Siguatepeque, 22.v.1972, (ca. 1600m asl), E.W. Stiles leg., FAAL .

Known distribution. Honduras and Guatemala.

Diagnosis and remarks. Regarding cercus morphology, H. eboratum is close to H. chrysops, H. valgum, H. calendulum and H. alienum, with which it shares the MP ridge bearing only small teeth and not partially covering ML. This species can be separated from these and the remainder of Group B species by the following character combination: BP subequal in length with AP, ML the shortest portion; ridge above ML short, bearing teeth on a single row (Figs. 31b–c); ML apex acute (Figs. 31b–c); AP with a longitudinal depression (Figs. 31b–c). Additionally, it is also worth mentioning that its ivory-white face contrasts with a mostly black thorax. According to the IUCN Red List, H. eboratum is considered Near Threatened as it occurs in isolated populations and its preferred habitats are under threat of deforestation (Paulson 2009).
