( Figs. 2C View FIGURE 2 , 4C View FIGURE 4 )
Studied material – 1; unknown. Holotype: 1 ( MZLU-MS) 11/ 14-IV-1994 at Aragua, Parque Nacional H. Pittier, La Trilla (200 m), ( Venezuela) L. Masner Col. (M.S.).
Etymology – This name was chosen because the malar furrow of this species is very weak.
Colour – Head, mesosoma and metasoma black. Antennae light reddish brown, except the last four flagellomeres, which are dark brown. Mandibles light yellowish brown with reddish brown teeth. Front and middle legs light brown, hind legs brown. Veins of wing yellowish brown.
Head – Head without pubescence, except for a line of hairs running from base of mandible along gena behind malar and postocular furrows and a few hairs forming a perpendicular line just below eye along upper part of malar furrow. Malar furrow very weak and curved, only marked by a change in the integument curvature; postocular furrow weak. Occipital carina strong. Pleurostomal lines weak. Malar space 0.70 times the height of the compound eye. Transfacial line 0.50 times the greatest width of the head and 1.17 times the height of a compound eye. Antennal foramina separated from each other by 1.6 times the distance between the foramen and the compound eye.
Antennae – F1 to F8 cylindrical with a very small expansion at the apex, following flagellomeres cylindrical. Length of F1 1.27 the length of F2. Antenna without pubescence, except for a few hairs on scape. Antennal formula: 8 (3): 3 (2): 7 (2): 5.5 (2): 5.5 (2): 5.5 (2): 4.5 (2): 4 (2): 4 (2): 4 (2): 4 (2): 4 (2.5): 8 (2.5). Placodeal sensilla start on F2 and they are little scarce on this antennomere.
Mesosoma – Lateral pronotal carinae projecting dorsomedially to form a much raised tooth ( Fig. 4C View FIGURE 4 ). Anterior pronotal plate with a few scattered hairs near dorsolateral margins and weakly transversely carinate. Lateral surface of pronotum with dense pubescence and with areolate sculpture. Mesoscutum in lateral view 1.58 times higher than long; in dorsal view 1.20 times wider than long. Median mesoscutal impression reaching 1/4 part of the length of the mesoscutum. Notauli complete ( Fig. 2C View FIGURE 2 ). Line of hairs on the anterior and lateral margins of the scutum absent. Scutellum in dorsal view of the same length as that of the mesoscutum. Scutellar foveae in anterior part with an internal short longitudinal carina dividing the anterior area of each fovea into two areas, scutellar foveae smooth with few irregular sculpture near its posterior margin. Lateral pit of scutellar fovea almost circular, 1.1 times longer than wide; the distance from median scutellar carina to the inner margin of the pit 3.5 times the width of the pit. Scutellar spine broad, narrowing abruptly before apex ( Fig. 2C View FIGURE 2 ). Scutellar disc in lateral view steeply slopping to base of scutellar spine, which is upwards directed at base and curved downwards, the apex is ventrally directed. Mesopleural impression rather narrow, weakly curved in the apical part and with few coarse transverse carinae ( Fig. 4C View FIGURE 4 ). Mesopleural triangle with sparse pubescence. Propodeum with areolate sculpture, lateral and median propodeal carinae present.
Wings – Marginal cell open 2.5 times longer than wide. R1 practically non-existent. Marginal pubescence of
the wing starting from the apical 2/3 of marginal cell but it is very sparse to the end of the cell.
Metasoma – Petiole between 1.0 and 1.5 times as long as wide, it is not possible to know exactly this measure because the third tergum is covering the posterior part of the petiole in the holotype. Petiole dorsally smooth, laterally and ventrally costate. Third abdominal tergum dorsally 0.65 times the length of the fourth tergum.
