Hadronotus blaches

Hadronotus blaches (Kozlov and Lê) (Figures 2 (a–f), 26(b)) Gryon blaches Kozlov and Lê, 1992: 225, 227 (original description, keyed). Gryon blachis Kozlov and Lê, 1996: 10 (description); Lê 2000: 98, 104 (description, keyed, type information). Male body length = 1.5 mm. Colour. Head, mesosoma and metasoma black; clypeus red-brown; mandibles red-brown, with dark brown teeth; all coxae and femur brown-black, remainder of leg brown. Head. 1.1× as wide as high. Sculpture of orbital furrow: foveate. Inner orbits in frontal view: converging dorsally. Central keel on frons: present, extending 0.6× the length of frontal depression. Malar sulcus: with shallow transverse depressions. Shape of frontal depression: ovoid. Width of frontal depression: 0.5× IOS. Sculpture of frontal depression: transversely carinate, with polygonal cells on either side of transverse carinae in ventral half; space between transverse carinae smooth. Submedian carina of frontal depression: entire. Sculpture of frons sans frontal depression: polygonal cells with rugose sculpture, setose. Sculpture of vertex: above dorsal margin of compound eye (in frontal view). Hyperoccipital carina: present. Sculpture of gena: polygonal cells with rugose sculpture. Mesosoma. Sculpture of mesoscutum: polygonal cells with rugose sculpture. Scutoscutellar sulcus: foveate. Sculpture of mesoscutellum: polygonal cells with rugose sculpture. Posterior mesoscutellar sulcus: foveate. Pronotal cervical sulcus: with depressions. Sculpture of lateral pronotal area: dorsally rugose, remainder transversely carinate with depressions between carinae. Prespecular sulcus: foveate. Sculpture of speculum: transversely carinate interspersed with foveae. Femoral depression: foveate. Episternal sulcus: foveate. Postacetabular sulcus: indicated as a furrow. Mesepimeral sulcus: foveate. Sculpture of posterior mesepimeral area: narrow and smooth. Mesopleural pit: present. Metapleural sulcus: with depressions. Metasoma. L: W of metasoma: 1.3× as long as wide. Basal foveae on T1: present. Sculpture of T1: longitudinally costate with uneven foveae between costae. Sculpture of T2: longitudinally costate, with depressions between costae; basal foveae absent. Length of T2: 4× length of T3. Sculpture of T3–T4: anteriorly with uneven foveae and posteriorly smooth. Female. Unknown. Material examined Holotype. male, VIETNAM: Gia Lai (An Khe, Buon Luoi), 16 June 1982, leg. Lê X.H. Diagnosis Hadronotus blaches is similar to H. westeberhardae sp. n. and H. peludo sp. n. but differs from them in the following character states: In H. blaches vertex in (frontal view) raised above dorsal margin of compound eye and submedian carina of frontal depression extends to ¾ of frontal depression, whereas in latter two species vertex (in frontal view) is not raised above dorsal margin of compound eye but evenly rounded; submedian carina of frontal depression restricted to dorsal half.
