( Fig. 2 )

Type locality. Ecuador, Aguarico Province, Yasuní.

Ventral coloration. Head including bucculae black with wide yellowish area in middle third; rostral segments dark brown with castaneous reflections; prothorax black with yellow collar; mesosternum yellow and laterally pale brown; metasternum dark brown with dark orange reflections; mesopleura black with small yellow spot at inner angle of posterior margin; metapleura black with posterior margin and acetabula yellow; anterior and posterior lobe of metathoracic scent gland auricle black; coxae and trochanters dark brown with dark orange reflections; fore and middle femora black with apical third dark yellow; hind femur black with apical third shiny yellowish orange; tibiae and tarsi dark castaneous orange; abdominal sternite III black with posterior margin pale yellowish orange; sterna IV–VI pale yellowish orange; sternite VII black with anterior angle including the abdominal spiracles orange; genital plates black.

Measurements (mm). Total body length 21.62. Head: length 1.48; width across eyes 2.85; interocular width 1.55; interocellar width 0.62; length of antennal segments: I – 5.76; II – 4.40; III – 3.47; IV – 6.01. Pronotum: length 4.46; width across humeral angles included the spiny projection 6.21. Scutellum: length 2.54; width 2.29.

Male. Unknown.

Differential diagnosis. Moronopelios flavoantennatus sp. nov. ( Fig. 2 ) is most similar to M. polystoides Brailovsky, 1988 ( Fig. 4 ), both sharing the yellow antennal segments I–III; dark yellow to orange posterior third of fore and middle femora, yellow posterior margin of metapleura; black abdominal sternite III with yellow posterior margin; and black sternite VII with yellow anterior angle.

However, M. flavoantennatus differs in the combination of black pronotum with yellow collar, and entirely black propleura and mesopleura. In M. polystoides the pronotum is black to reddish brown with collar, posterolateral margins, posterior margin and two short longitudinal stripes running from below calli to posterior third of pronotal disk yellow, and fore and middle acetabula, and posterior margin of propleura and mesopleura yellow.

Etymology. The species epithet is a Latin adjective, composed of flavus (-a, -um; = yellow) and antennatus (-a, -um; = antennate), referring to the yellow colouration of the three basal antennal segments.

Distribution. Known only from Ecuador.
