Comparative diagnosis

The new species is similar to A. imparidens Fischer, 1974 ( Fischer 1974b) and A. laevinota Tobias, 1962 ( Tobias 1962) . Aspilota grandis sp. nov. differs from A. imparidens in having the first flagellar segment 3.3 times as long as its maximum width (7.0 times in A. imparidens ), middle segments 1.3– 1.5 times as long as their maximum width (3.0 times in A. imparidens ), hind femur 4.0 times as long as its maximum width (4.3 times in A. imparidens ), and precoxal suture not reaching anterior or posterior margins of mesopleuron (reaching anterior margin in A. imparidens ). Also, the new species differs from A. laevinota in having the face 1.8 times as wide as high (1.5 times in A. laevinota ), the first flagellar segment 3.3 times as long as its maximum width (7.0 times in A. laevinota ), middle segments 1.3–1.5 times as long as their maximum width (3.0 times in A. laevinota ), and vein r2 (3-SR) 1.7 times as long as vein cuqu1 (2-SR) (1.5 times A. laevinota ).

Etymology

The name is derived from Latin “grandis”, meaning “big”, referring to the size of the species.

Mandible widened towards apex, 1.7 times as long as maximum width. Upper tooth of mandible distinctly shorter than middle and lower teeth; middle tooth long and pointed; lower tooth longer than upper tooth, rounded apically. Antenna thick, 21 - segmented. Scape 3.0 times as long as pedicel. First flagellar segment 3.3 times as long as its apical width, 1.6 times as long as second segment; 2 nd segment 2.0 times as long as its maximum width, 3 rd segment 1.8 times, 4 th to 8 th 1.5–1.6 times, 9 th to 18 th 1.3–1.4 times, and 19 th (apical) 1.8 times as long as their maximum width, respectively.

Prescutellar depression smooth, with median and lateral carinae. Precoxal suture present, reaching anterior margin of mesopleuron. Posterior mesopleural furrow crenulate. Propodeum sculptured, without areola. Propodeal spiracle small.

LEGS. Hind femur 4.0 times as long as its maximum width. Hind tibia slightly widened towards apex, 9.2 times as long as its maximum subapical width, about as long as hind tarsus. First segment of hind tarsus twice as long as second segment.

WINGS. Length of fore wing 2.5 times its maximum width. Radial (marginal) cell ending at apex of wing, 3.5 times as long as its maximum width. Vein cuqu1 (2-SR) present and sclerotized. Vein r2 (3- SR) 1.7 times as long as vein cuqu1 (2-SR); vein r3 (SR1) 2.5 times as long as vein r2 (3-SR). Nervulus (cu-a) distinctly postfurcal. Brachial (subdiscal) cell closed distally, 3.0 times as long as its maximum width. Hind wing 4.8 times as long as its maximum width.

METASOMA. Distinctly compressed. First tergite striate, slightly widened towards apex, twice as long as its apical width. Ovipositor as long as first tergite, distinctly shorter than metasoma, 0.8 times as long as hind femur.

COLOUR. Body, antenna and pterostigma dark brown. Mandible and legs brown. Wings hyaline.

LENGTH. Body 3.1 mm ; fore wing 3.6 mm ; hind wing 2.8 mm .
