Petersitocoroides vergarae sp. nov.

( FIGS. 1–6 )

Type material. Holotype male, Peru, Junín, Chanchamayo, “Fundo Génova” (11°05’47.58’’S; 75°21’00.39’’O, 966 meter above sea level), collected by L. Cruces in 02.VI.2010. ( UNALM). Paraypes: 4 males, same locality data as holotype, 2 collected by L. Cruces on 02.VII.2010 and 02.VII.2010, and 2 collected by E. Arana on 03.VII.2010 ( UNALM, UNAM).

Description. Male holotype: Dorsal color. Head yellow with reddish brown punctures; antennal segments I to III yellow with reddish brown tubercles, and IV with anterior half pale castaneus orange and posterior half yellow; ocellus reddish; anterior third of pronotum pale yellow with pale castaneus punctures, middle and posterior third yellow suffused with pale green irregular marks, and with reddish brown punctures; humeral angles darker; pronotal disk with three pale yellow longitudinal stripes: one central well-defined and two parallel sides incomplete; scutellum yellow with reddish brown punctures and a single pale yellow longitudinal stripe extended to the apex; c1avus and corium yellow; claval and corial veins, and most of the costal edge, paler, and punctures reddish brown to pale castaneus orange; apical angles and apical margin, dark castaneus orange; hemelytral membrane translucent, veins dark amber, and basal angle and inner margin dark brown with a short, irregular stain that runs between the external and middle margins; connexival segments III–IV entirely yellow; dorsal abdominal segments bright orange with some blackish markings. Ventral color. Pale yellow, including head, thoracic and abdominal segments, genital capsule, legs and rostrum except its apex which is dark castaneus.

Variation. The yellow colouration of the body can be replaced by a more opaque and dark ocher. Connexival segments with black punctures in the angle and margin of the posterior third.

Head: Antenniferous tubercle unarmed; antennal segment I carinated, somewhat curved outward and gradually thickened; postocular tubercle moderately protuberant; rostrum reaching posterior margin of metasternum.

Thorax: Pronotum wider than long; frontal angles forward as medium sized conical lobe, blunt; humeral angles rounded, not exposed, slightly raised above pronotal disk ( FIG. 1 ).

Legs: Femora unarmed; tibia unarmed, sulcate.

Abdomen: Male genital capsule. Posteroventral margin simple, without tubercle; posteroventral edge mesially invaginated seeing externally a deep cleft ( FIGS. 3–4 ). Parameres elongate, with anterior lobe embossed and folded on itself; posterior lobe elongate, triangular with an acute tip ( FIG. 2 ). Aedeagus: vesica short in spiral; conjunctiva presenting dorsally two somewhat rectangular large processes, covering more than two thirds of the length of the conjunctiva, and projecting downwardly reaching and exceed half the phallobase; laterally has two small ventral conjunctive processes and develops a lobe on which appear two medium sclerotized processes of quadrangular shape ( FIGS. 5–6 ).

Measurements. Male holotype: Head length 1.60; width across eyes 1.88; interocular distance 1.12; interocellar distance 0.62; preocular distance 1.10; length of antennal segments: I, 1.47; II, 2.10; III 1.71; IV, 1.75. Pronotum: Total length 2.13; width across frontal angles 1.65; width across humeral angles 3.51. Scutellar length 1.48; width 1.39. Total body length: 10.11

Female. Unknown.

Distribution. Peru (Junín)

Etymology. Named for Clorinda Vergara, distinguished Peruvian entomologist. Gender feminine.
