Description of Male Holotype.— Length of body 2.7 mm.

Head.— 1.32 times as long as wide, elongate in dorsal aspect, fairly strongly narrowing behind and evenly rounded towards occipital carina. The distance from the eyes to the occipital carina more than 1.5 times the length of the eyes in dorsal aspect. Ocellar triangle forms a slightly acute angle at the anterior ocellus. Lateral ocelli are distributed slightly closer to anterior ocellus than the maximum diameter of the latter. Occipital carina from hind ocelli at a distance of 1.75 times of the maximum diameter of the latter. Surface of head finely coriaceous with sparse punctures. Length-to-width ratios of antennomeres: scape: 3.3, pedicel: 1.7, 1st flagellomere: 1.8, 5th flagellomere: 1.7. Terminal palpomere of maxillary palps ca. 4 times longer than wide.

Mesosoma.— With a length-to-depth ratio of 3.4 and length-to-width ratio of 2.6. Pronotum elongate and narrow anteriorly, with a narrow horizontal shelf protruding above base of propleuron. Length-to-width ratio of propodeal disc 1.3. Radius with a node in its basal 1/7. Distal end of pterostigma continuing as an extremely short metacarpal vein. Fore femur greatly swollen, with a length-to-width ratio of ca. 2.0. Hind trochanter with a ventral tooth. Hind femur flattened beneath, with a basal tooth and smaller median tooth (paratypes) or swelling (holotype) on the inner edge as well as with a median swelling on the outer lateroventral edge.

Metasoma.— Eighth sternite with distal margin broadly emarginate, centrally with sparse setae. Subgenital plate with distal margin deeply emarginate, centrally narrowly with an even deeper second emargination, with setae centrally.

Male genitalia.— Distal part of parameres with long setae, central part broad. Volsella with digitus not clearly visible. Aedeagus as illustrated.

Colour.— Brown. Antennae in the basal half, palps, mandibles, tarsi, fore tibiae, mid and hind tibiae subbasally and apically yellow.

Etymology.— From Latin ( elongatus meaning Lenghtened) Named after the elongate head and mesosoma.
