Parascepsis ockendeni
(Rothschild, 1911)
comb. nov.
(
Figs. 9–20
)
Episcepsis ockendeni
Rothschild, 1911: 44
. Male
holotype
by original designation:
Peru
, Santo Domingo, Carabaya, 6000-6500ft (BMNH) [Specimen examined]; Rothschild, 1912: 375, pl. 3, f. 9;
Episcepsis occendeni
[sic]
Hampson, 1914: 244
.
Diagnosis:
Similar to
P. lantingi
. It differs in the tegulae and patagia being grayish brown, while in
P. lantingi
they are metallic green. On the forewings,
P. lantingi
presents, under 1A + 2A, a subproximal yellowish androconial patch and, at the hindwings, the costal cell with an elongated and somewhat ovoid area with small light brown spicules, absent in
P. ockendeni
.
In the genital capsule,
P. ockendeni
bears a translucent subquadrate area, sclerotized spicules at the fultura superior, the vesica of the aedeagus with cornuti at the dorsal surface and projecting to the right side, while in
P. lantingi
,
the translucent area is ovoid, there are no spicules at the fultura superior and the cornuti at the proximal area direct towards the right side of the posterior part.
Redescription. Male

Proximal rami small, increasing in length towards the middle part. Length of the middle rami almost twice the width of the shaft. Distal rami decrease in length towards their distal end.
Thorax
. Patagia grayish brown at the edges. Tegulae grayish, with brown mesal edge and an oblique brown line projecting towards the base of the wing; brown in the anterior part. Mesoscutum, mesoscutellum, and pleura grayish brown. A faint brown line along the central part of the mesoscutum and mesoscutellum. Metascutellum with grayish brown piliform scales on the side. Tymbal organ at the katepisternum covered by grayish brown scales. Legs: Grayish brown; except the first pair, with lighter scales on the anterior part. Epiphysis brown.

Male genitalia
(
Figs. 13–16
) (Genitalia # JGA 775 MUSM). Tegumen somewhat elongated, anterior part concave and shaped as an inverted “V”; with a translucent subquadrate area, anterior part obtuse and posterior one sharp; on the lateral part with a somewhat sclerotized projection, almost the width of the translucent area. Saccus elongated, sharp with rounded apex. Joining of the tegumen and uncus, sclerotized. Uncus elongated, wider towards the central part; curved downward ventrally on the tip. Juxta wide and sclerotized, posterior part “W” shaped. Transtilla with an area of sclerotized spicules. Valvae elongated exceeding the length of the uncus; sacculus with numerous setae and costa with some; ventral process short, with apex sharp and sclerotized, almost a third of the length of the dorsal process; dorsal process membranous with numerous setae; in ventral view, valvae elongated, with somewhat irregular edge, arched towards the middle axis and with numerous setae at the mesal margin; dorsal view, in dorsal and distal part with a sclerotized projection towards the middle axis with setae present. Aedeagus elongated, slightly longer than the vesica; coecum penis slightly developed; vesica everted dorso-longitudinally; cornuti elongated, located on the dorsal surface and projecting to the right side; posterior part membranous with tiny spicules somewhat sclerotized on the postero-ventral part.
Female
(
Figs. 11–12
). Forewing span (
18–20 mm
) (n = 7). Similar to the male, except for the following: rami smaller; middle rami almost half of the shaft width. Frenulum light brown with two bristles.
Female genitalia
(
Figs. 17–18
) (Genitalia # JGA 992 MUSM). Eighth tergite uniformly sclerotized. Anal papillae elongated, with setae scattered on the posterior and latero-ventral surface; in lateral view, the length 1.5 times its height. Posterior apophyses 1.2 times the length of the anterior ones. Ostium and antrum of central position. Antevaginal lamella membranous. Postvaginal lamella slightly sclerotized. Ductus bursae sclerotized, striate, wide and flattened dorsoventrally. Cervix bursae membranous. Corpus bursae membranous, elongated; in dorsal view, subrectangular. A semicircular signum on the dorsal surface, in posterior and left lateral position, with some spines; another elongated signum at the right lateral surface. Ductus seminalis emerges near the first signum.

Comments:
P. ockendeni
was described by Rothschild (1911) within the genus
Episcepsis
Butler
, with
type
location at
Santo Domingo
,
Carabaya
(department of
Puno
,
Peru
), with material collected by G.
R
.
Ockenden
, who spent several years collecting insect specimens in southeastern
Peru
(
Grados
et al.
2015
)
.
According to preliminary studies of phylogeny based on morphological characters of the genus
Episcepsis
Butler
, this would be polyphyletic. When including both
E. ockendeni
and
P. solox
to the phylogenetic analysis they form a different clade together, indicating
E. ockendeni
to belong to the genus
Paracepsis
.
Parascepsis
is characterized for its occiput bearing whitish gray piliform scales, with three dark brown lines: a straight central one and two lateral ones in the direction of the antennae, while
Episcepsis
presents two red spots on the lateral parts of the occiput; R
1
-R
2
at the anterior wing of
Parascepsis
is bifurcated while in
Episcepsis
R
1
and R
2
are separated; in
Parascepsis
the dorsal part of the abdomen is grayish brown with a slight bluish hue, while in
Episcepsis
it is brown with an iridescent blue hue
Parascepsis
can present androconial patches in the anal cell of the forewings and an elongated area with brown spicules in the costal cell of the hindwings, whereas in
Episcepsis
both are absent and they bear an androconial organ (tufts of hair) in the 1A+2A-3A of the dorsal side of the hindwings;
Parascepsis
have the tegumen slightly Hshaped with posterior elongated branches that join the anterior part of the uncus and form a wide area covered with a translucent membrane that projects towards the lateral parts, while in
Episcepsis
the tegumen is wide, somewhat subrectangular and some species bear projections at the postero-lateral parts; the males of
Parascepsis
have a wide, almost straight aedeagus, while in
Episcepsis
the aedeagus is narrower, slightly sinusoid.
On the other hand, there is
Hyaleucerea lugubris
Schaus, 1901
, a species described from
Colombia
, unfortunately without an exact type locality, whose
holotype
is in the USNM. Based on the external morphological characters that have been possible to analyze for both species,
P. ockendeni
is very similar to
Hyaleucerea lugubris
. For now, it has not been possible to review the morphological characters of the latter’s genital capsule, so it is not possible to state that
P. ockendeni
is a junior synonym of
H. lugubris
.
