Holotype, female ( ICAR / NBAIR / P4970 ), INDIA: Karnataka: Bengaluru, Hebbal, Indian Veterinary Research Institute , 13.023°N, 77.584°E, ca 900 m, YPT, 16 November 2017 ; Paratype: one female ( ICAR / NBAIR /P4971), Karnataka: Bengaluru, GKVK, 13.080°N, 77.578°E, ca 930 m, YPT, 22 May 2013.

Etymology

This species is named after the Canadian primatologist Birute Mary Galdikas, one of Louis Leakey’s ‘Trimates’ or angels, whose work on the orangutans of Indonesian Borneo for the first time uncovered the solitary lives of the males of these then least known of the great apes, among many other aspects of their lives in the wild. The name is treated as a noun in the genitive case.

Diagnosis

Hadronotus galdikasae sp. n. is similar to H. circus but differs from it in having an incomplete central keel on the frons, while in H. circus the central keel on frons extends the entire length of the frontal depression.
