(Figures 7 (a–g), 26(f))
Female body length = 1.05–1.15 mm (n = 2). Colour. Head, mesosoma and metasoma black; all coxae and femur dark brown, remainder of leg brown-yellow; clypeus yellow-brown; mandible yellow-brown with black-brown teeth; entire antenna yellow-brown.
Head. 1.6× as wide as high, 1.2× as high as long. IOS: 0.6× head width, 1.3× eye length. POL: LOL: OOL: 17.6: 7.9: 2.9. OOL: subequal to MOD. Compound eye: ovate (L: W = 17.7: 14.3). Sculpture of orbital furrow: foveate. Inner orbits in frontal view: converging dorsally. Central keel on frons: present, extending half the length of frontal depression. Malar sulcus: indicated as a furrow with rugose sculpture. Shape of frontal depression: triangular. L: W of frontal depression: 21.5: 28.9. Width of frontal depression: 1.2× IOS. Sculpture of frontal depression: with discontinuous transverse carinae dorsally, space between carinae smooth; ventrally with sparse transverse carinae on either side of central keel, in addition to curved or crescent shaped carinae laterally with reticulations between carinae; reticulate ventrally. Submedial carina of frontal depression: entire. AOD in dorsal view: 3× OOL. Sculpture of frons sans frontal depression: foveate, setose. Sculpture of vertex: with polygonal cells, setose. Hyperoccipital carina: present. Sculpture of gena: weakly foveate.
Mesosoma. L: W of mesoscutum: 24.1: 37.5. Sculpture of mesoscutum: coriaceous reticulations with longitudinal carinae posteriorly. Scutoscutellar sulcus: foveate. L: W of mesoscutellum: 9.8: 28.8. Sculpture of mesoscutellum: coriaceous reticulate with sparse longitudinal carinae, setose posterolaterally. Posterior mesoscutellar sulcus: foveate. Sculpture of metascutellum: anteriorly foveate, posteriorly smooth. Posterior margin of metascutellum: semicircular. Sculpture of metanotal trough: foveate. Lateral propodeal area: laterally wide and narrowing centrad, with a weak medial notch. Sculpture of lateral propodeal area: with depressions. Posterior propodeal projection: not pointed. Pronotal cervical sulcus: with depressions. Sculpture of lateral pronotal area: dorsally foveate, ventrally smooth with transverse carinae. Prespecular sulcus: transversely foveate. Sculpture of speculum: transversely carinate. Femoral depression: transversely carinate, area between carinae smooth. Episternal sulcus: not foveate. Postacetabular sulcus: indicated as furrow. Mesepimeral sulcus: foveate dorsally. Sculpture of posterior mesepimeral area: absent. Mesopleural carina: indicated ventrally. Mesopleural pit: present. Metapleural sulcus: foveate. Sculpture of dorsal metapleural area: foveate, sparsely setose. Sculpture of ventral metapleural area: smooth to rugose, sparsely setose. Paracoxal sulcus: foveate. L: W of fore wing: 71.9: 34.0. Ratio of length of m: st: pm: 2.1: 6.7: 0; postmarginalis absent. L: W of hind wing: 58.1: 15.1. Length of hind wing marginal cilia: 0.18× width of wing. Shape of submarginalis: straight, distant from anterior margin of wing and dips before reaching marginalis.
Metasoma. L: W of metasoma: 38.9: 44.3, 0.9 × as long as wide. Anterior margin of T1: almost straight. Basal foveae on T1: present. Sculpture of T1: longitudinally costate, space between costae medially smooth, laterally rugose; posteromedially smooth. Sculpture of T2: finely reticulate; basal foveae absent. Length of T2: 5.9× length of T3. Sculpture of T3– T4: smooth. Setation of metasoma: T1 densely setose laterally; T2 sparsely setose laterally; posterior tergites sparsely setose.
Male. Unknown.

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.
