Diagnosis

Zischkaia chullachaki sp. nov. is similar to Z. baku sp. nov., but is distinguishable based on posterior projection of tegumen being curved in lateral view (posterior projection of tegumen is rather straight in Z. baku sp. nov.); posterior projection of tegumen narrow in dorsal view (posterior projection of tegumen rather broad in dorsal view in Z. baku sp. nov.); winglet of aedeagus reduced, almost absent (winglet of aedeagus prominent, clearly visible in Z. baku sp. nov.); sclerotized tube reduced, almost

invisible in lateral view in Z. chullachaki sp. nov. (sclerotized tube about half the length of ductus bursae in Z. baku sp. nov.).

Etymology

The specific epithet is derived from a mythological creature, Chullachaki, a ‘forest guardian’ known from the Peruvian and Brazilian jungle, in reference to this species known from the Peruvian and Brazilian Amazon. This specific epithet is regarded as a Latinized masuculine noun in apposition.

Tegumen rounded in lateral view, elongated posterior projection of tegumen developed, curved upwards in lateral view, apparently shorter than uncus, tapering posteriorly and hooked at terminal point, posterior end of ventral margin appearing as small projection; combination of ventral arms of tegumen and dorsal arms of saccus sinuous, broadens towards saccus; appendices angulares present, but somewhat reduced; saccus straight, similar to uncus in length; uncus long and narrow, sparsely with hair-like setae, curved in lateral view, rounded at terminal point forming small ‘bulb’; either side of base of uncus with hair-like setae; brachia similar to uncus in length and width, curved in lateral view, tapering posteriorly and crossing over each other near terminal point; fultura inferior (i.e., juxta) present; valva subtriangular in lateral view, apical process subtriangular, dorsal margin convexed, ventral margin concave, scarcely covered by hairy-like setae, costa developed and triangular, dorsal margin slightly sinuous; phallobase about two-fifth of phallus, rather straight; ductus ejaculatorius coming out higher than anterior end of coecum; aedeagus straight with manica covering about half, winglet present, distal opening located ventrally where vesica is visible.

Female

FW length 23 mm (n = 2).

Similar to male except as follows: foreleg whitish, foretarsus first and second subsegments fused; forewing appears slightly more rounded and broad, ground color of both wing surfaces paler; dorsal androconia absent.

FEMALE ABDOMEN AND GENITALIA (Fig. 6 A–B): inter-segmental membrane between seventh and eighth tergite not pleated, but folded posteriorly of ostium bursae with its sclerotized region forming a ‘scooplike’ structure below lamella antevaginalis; lamella antevaginalis fused to lateral sclerotized plate of eighth abdominal segment; lateral plate of eighth abdominal segment expanding laterally with small spiracle at superior third; ductus bursae membranous with a half-ring strongly sclerotized at the median region; corpus bursae three times longer than ductus bursae, with paired signa ventrally occupying ⅔ its length.

Variation

The VHW ocellus in Rs-M 1 is variable in terms of size and presence.

Distribution (Fig. 14)

This species is known from the western Amazon basin (Junín, Puno and Madre de Dios, Peru, and Acre, Brazil).
