Diagnosis

This is one of the smallest Deranchylaeus species (together with H. xanthostoma and H. venustus ). The fine sculpture and shield-like shape of the propodeum are diagnostic. The mask of the male and the mouth parts are pale yellow. It belongs to the curvicarinatus-group.

Characteristic features

Male. TL 3.4–4.8 (4.17) mm, WL 2.4–3.3 (2.86) mm.

Head. Proportions HL:HW 0.98, UFW:LFW 1.69, shape prolonged trapezoid. Scapi short cylindrical, apically with a light spot, SL:SW 1.7; flagella long, mostly pale yellow. Mask light yellow, complete, side patches reaching up to antenna bases, lower (or upper) half of supraclypeal area yellow. Clypeus CL:CW 1.49, slightly shining. Frons and vertex with moderate, close punctation, punctures shallow. Labrum and mandibles white.

Mesosoma. Pronotum with two yellow lines, calli and tegulae pale. Pronotum narrow; anterior margin lamellate, sharp toward corners, posterolateral angles blunt. Mesonotum and scutellum with moderate, close punctation. Legs black, except basis and top of tibiae, tarsi; wings hyalin, venation brown. Propodeum edged, terminal area sharp around, shield-like sublime, angles between terminal area and lateral area pointed, medial area with few longitudinal wrinkles.

Metasoma narrow spindle-shaped, black. Sculpture fine shagreen, silky shining, punctation of T1 minute, scattered, still recognizable. Terminalia ( Fig. 12 View FIGURES 12–15 ): genital capsule regularly oval in outline, S8 apically blunt, S7 basal lobi with 5 setae, of curvicarinatus type.

Female. TL 4.5–5.0 (4.81) mm, WL 2.8–3.8 (3.39) mm.

Head. Proportions HL:HW 0.98, UFW:LFW 1.49, outline nearly circular. Face with short bright lines near foveae. Clypeus CL:CW 1.43, sculpture Fig. 37 View FIGURES 36–37 .

Mesosoma. Coloration entirely black. Pronotum little expanded forward, edged in front, dorsolateral angles blunt. Mesonotum and scutellum slightly shining; mesopleurae only shallowly punctate, matt; propodeal terminal area with surrounding margin, ridge between lateral and terminal area not always very clear, otherwise as in male.

Metasoma slender spindle-shaped, black. T1 with narrow white bands on depressions broadly interrupted; sculpture otherwise as in male.
