Araujo, Rodrigo De Oliveira, Vivallo, Felipe & Araujo, Cristina De Oliveira, 2013, Five new species of Baeus Haliday, 1833 (Hymenoptera: Platygastroidea: Scelioninae) from Brazil with an updated key to Neotropical species, Zootaxa 3670 (1) : -

Baeus morenus Araujo & Vivallo new species

( Figs. 13–15 and 17 )

Diagnosis. This species is similar to Baeus leucophthalmus new species by the presence of dense pilosity on the dorsal surface of the body and by the triangular distal margin of the clypeus. Both species differ in body proportions, especially the relationship between POD and OOD, and by the length of the clypeus, two times shorter in B. morenus new species than in B. leucophthalmus new species

Description. Holotype female: Body length: 0.61 mm.

Body brown. All legs with coxa and trochanter yellow, femur and tibia brown with yellow distal end. Tarsomeres brown with yellow tarsal claws. Dorsal side of head, mesosoma and metasoma slightly darker than lateral and ventral body sides. A1 with brown basal half and pale yellow distal half. A2 brown with yellow apex. A3 brown. A4–A6 light yellow. Antennal club brown.

Head 1.17 times as wide as high (frontal view), 1.27 times as wide as mesosoma (dorsal view) and 2.96 times as long as malar space (lateral view). Distal edge of the clypeus short and triangular ( Fig. 17 ). Interorbital distance 1.3 times as long as the width of the compound eye (frontal view). POD 11.92 times as long as OOD. A1 1.11 times as long as sum of A2–A6. A2 1.95 times as long as wide. Antennal club without traces of sutures marking line of separation between clavomeres, 2.17 times as long as wide and 1.33 times as long as the sum of A2–A6. Mesoscutum transverse, 1.36 times as wide as long.

Metasoma 1.05 times as wide as head and 1.33 times as wide as mesosoma. T7 with rounded distal edge.

Male: Unknown.

Type material. Holotype female: Brazil, Rio de Janeiro, Parque Nacional de Itatiaia, 18.VI.2011, 2176 m., Araujo, R. coll. Entomological sweep net (MNRJ).

Etymology. The name of the new species comes from the Latin “ maurus ” referring coloration of the body.
