A comparison of the habitus shows that the new species is different from all other species of Neolucanus. Each male mandible has a
long, large carina protruded upward and inward along the upper side, which is not present in other species.
The new species possesses a long upward and inward carina on each mandible. It does not exhibit the characteristics of any of the above groups.
In comparing habitus with other species, the new species, Neolucanus baongocae, is closest to the medium form of Neolucanus fuscus Didier, 1926, from Tam Dao National Park (Vinh Phuc, Vietnam).
The new species, N. baongocae, was found in an undisturbed forested mountain area of Bidoup—Nui Ba National Park, Lam Dong Province. Specimens were collected during the day and when walking around and at night by light traps. The elevation of the collection site was 1550-1623m.
The research was published in the journal Zootaxa last month.
