( Figs. 2B , 4B )

Studied material – 2 & 2. Holotype: 1 ( NZLU-MS) 25-II-1983 at Pich, Rio Psique , 5 km N of Guallabamba, ( Ecuador) L. Huggert col. Paratypes: Ecuador: 1 ( MZLU-MS), 13-II-1983 at Napo, Baeza, L. Huggert col. Nicaragua: 1 ( UB) , 18-XII-94 at Carr. Matagalpa, Jinotega J. M. Maes col. 1 ( MACN) .

Etymology – This name was chosen to honour Dr. Lars Huggert, Sweden, who has collected the type specimen.

Length of head + mesosoma + metasoma in female: 2.58 mm; in male: 2.63 mm.

Colour – Female. Head and mesosoma black, metasoma blackish brown. Antennae light or reddish brown. Mandibles light yellowish brown with reddish brown teeth. Legs light brown with exception of the basal 2/3 of the metacoxa, which is dark brown. Veins of wing yellowish brown. Male. Differs from female in having scape and pedicel light brown, flagellomeres medium to dark brown, lighter lateroventrally.

Head – Female. Head with scattered short hairs. Malar furrow in upper part very curved. Postocular furrow present. Occipital carina strong. Malar space 0.58 to 0.62 times the height of the compound eye. Transfacial line 0.53 to 0.56 times the greatest width of the head and 1.15 to 1.16 times the height of a compound eye. Pleurostomal lines very marked. Antennal foramina separated from each other by 1.17 to 1.20 times the distance between the foramen and the compound eye. Male. Malar space 0.6 to 0.7 times the height of the compound eye. Transfacial line 0.54 to 0.58 times the greatest width of the head and 1.11 to 1.25 times the height of the compound eye. Antennal foramina separated from each other by 1.25 to 1.29 times the distance between foramen and the compound eye.

Antennae – Female. Pubescence of the antenna practically indistinguishable. F1 to F3 cylindrical with a very small expansion at the apex, following flagellomeres cylindrical. Length of F1 1.25 to 1.28 the length of F2. Antennal formula: 7 (2.5): 3 (2): 7.5 (1.5): 6 (1.5): 5.5 (2): 5.5 (2): 5.5 (2): 5 (2): 4.5 (2): 4.5 (2): 4.5 (2): 4 (2): 8 (2). Placodeal sensilla start on F2 but they are absent on dorsal part of this antennomere, on F3 and F4 they are scarce on dorsal part. Male. Flagellomeres cylindrical. Length of F1 1.2 to 1.4 the length of F2. Antenna without pubescence. Antennal formula: 7 (3): 3 (3.5): 12 (2.5): 8.5 (3): 8 (3): 8.5 (3): 9 (3): 8.5 (3): 8 (3): 9 (3): 8 (3): 7 (3): 7 (3): 10.2 (3). F1 to F5 and weakly in basal 1/3 of F6 slightly expanded dorsolaterally with a longitudinal ridge on the raised part. Placodeal sensilla start on F1 and they are not scarce on this segment.

Mesosoma – Female. Anterior pronotal plate almost glabrous with coriaceus sculpture. Lateral pronotal carinae projecting dorsomedially to form a blunt, little tooth ( Fig. 4B ). Lateral surface of pronotum with scattered hairs and with coarse areolate sculpture. Mesoscutum in lateral view 1.6 times higher than long; in dorsal view 1.29 times wider than long. Median mesoscutal impression very short, at most little longer than broad. Notauli reaching 1/2 or 1/3 the length of mesoscutum ( Fig. 2B ). Line of hairs on the anterior and lateral margins of the mesoscutum absent. Scutellum in dorsal view of the same length as that of the mesoscutum. Scutellar foveae smooth with some weak sculpture at its posterior margin. Lateral pit of scutellar fovea rather small and almost circular, 1.2 times longer than wide; the distance from median scutellar carina to the inner margin of the pit 4.0 times the width of the pit. End of scutellar disc narrowing abruptly to base of scutellar spine, which is slender all the way ( Fig. 2B ). Scutellar disc in lateral view steeply slopping to base of scutellar spine. Scutellar spine straight not directed ventrally ( Fig. 4B ). Mesopleural impression rather narrow straight and with few transverse carinae. Mesopleural triangle glabrous.Propodeum areolate but not coarsely, median and lateral propodeal carinae present. Male. Mesoscutum in lateral view 1.60 to 1.67 times higher than long; in dorsal view 1.15 to 1.33 times wider than long. Scutellum in dorsal view of the same length as that of the mesoscutum. Lateral pit of scutellar fovea 1.20 to 1.33 times longer than wide; the distance from median scutellar carina to the inner margin of the pit 3.33 times the width of the pit. Mesopleural impression with only one or two weak transverse carinae.

Wings – Female. Marginal cell open; between 2.70 and 2.80 times longer than wide. R1 practically non-existent. Marginal pubescence of the wing starting from vein R1. Margin of the marginal cell sparsely pubescent anteriorly and densely pubescent apically. Male. Marginal cell 3.14 to 3.44 times longer than wide; its margin rather densely pubescent anteriorly and apically.

Metasoma – Female. Petiole between 1.7 and 2.0 times as long as wide. Petiole dorsally smooth laterally and ventrally longitudinally costate. Third abdominal tergum dorsally between 0.60 and 0.71 the length of the fourth tergum.
