Diagnosis.
Palpita persicalis
was originally described in the genus
Apyrausta
by
Amsel (1951)
. It shows external characters of lighter coloured species of the genus
Pyrausta
or
Metasia
, but the genitalia are characterized for the tribe
Margaroniini
, especially for the genus
Palpita
of which other Palaearctic species are externally more or less different.
Description of the female.
Essentially as in male.
Head
(
Fig. 12E, G
): Vertex covered with slightly appressed yellowish-creamy scales; frons with nearly smooth, yellowish-creamy scales except grayish-brown scales forming a pair of parallel strips medially; labial palpus porrect, with third segment downwardly directed, upper half brown, lower half creamy-white, with length slightly less than twice the horizontal diameter of compound eye (n = 4); maxillary palpus small, dark brown dorso-laterllay except creamy dorso-apical part; antennae ringed with creamy and pale brown scales, ciliae sparse, very short.
Thorax
: yellowish-creamy admixed with brown scales dorso-medially; fore tarsus with large dark brown spots, those of the remaining legs with clearly paler. Forewing (
Fig. 12A, B
) elongate, nearly triangular, rounded apically, straight at costa, with length of
9.80–10.20 mm
(x =
9.95 mm
± 0.19, n = 4); upperside pale yellowish-white, with scattered brown scales, a relatively wide longitudinal light brown costal strip, clear circular and kidney-shaped spots at median part bordered with dark brown scales and grayish-pale brown internally, an indistinct dark brown spot between kidney-shaped spot and apex, a hardly visible dark brown cross line at proximal one-sevenths, and a narrow dark brown marginal line accompanied with dark spots, fringes white, shiny, with wedge-shaped dark brown spots, tips against dark spots of the marginal line. Hindwing upperside pale yellowish-white, with a small and elongate nearly comma-shaped dark brown spot at distal part of discoidal cell, and scattered dark brown scales around the spot, marginal line same as the forewing, fringes white, shiny, with hardly visible pale brown wedge-shaped spots basally. Undersides of the wings shiny, slightly paler than the upperside, with traces of spots and marginal lines.
Abdomen
: Yellowish-creamy. Female genitalia (
Fig. 13A‒D
) with papillae anales having narrow, elongate, densely setose lobes; ostium bursae broad, about one-fourth width of the segment; anterior apophyses about 1.5 times as long as posterior apophyses (n = 2); antrum cup-shaped, almost membranous, except sclerotized anterior margin; colliculum ring-shaped, sclerotized; ductus bursae short, membranous, nearly one-fourth length of bursa copulatrix, with an anteriorly directed pyramid-shaped process at dorsal side and a slightly shorter finger-shaped process directed posteriorly at ventral side (
Fig. 13A‒C
); ductus seminalis emerging from posterior end of ductus bursae, nearly at the junction with colliculum; bursa copulatrix membranous, oblong, distinctly narrow at anterior half and broad at posterior half, more than half length of the genital aparatus; signa (
Fig. 13A, D
) as two hornshaped, large, elongate, ventrally located sclerotized structures at the posterior end of bursa copulatrix having circular to oval bases.
Distribution.
Iran
:
Fars Province
(Sineh Sefid [
type
locality], Komehr) (
Amsel 1951
).
Remarks.
This species was described by
Amsel (1951)
based on
five males
collected in
Fars province
(Sineh Sefid and Komehr) and since then the female has remained undescribed. During this study,
four females
that match
P. persicalis
, from the same locality as males, were found in the HMIM
Lepidoptera
collection. Because the males and females are superficially similar, the females are considered to be conspecific with
P. persicalis
.
Our examination shows that the male specimens had wider antennae with very short, dense ciliae (
Fig. 12F, H
). Additionally, the male specimens had more scattered brown spots on both upper and underside of their wings compared with the females (
Fig. 12C
). Length of the forewing in the examined males is 8.0–
11.2 mm
(x =
9.08 mm
± 9.95, n = 9), with wingspans of
18–24 mm
(x =
19.72 mm
± 1.97, n = 9). Based on
Amsel (1951)
, the
type
material had wingspan of
20–24 mm
.

According to
Amsel (1951)
, in
P. persicalis
wings have no traces of yellow colour, and forewing have a dark area between costa and subcosta. Another form of this species,
P. persicalis
f.
sulfuralis
was discovered by
Amsel (1951)
at that time which had been collected from Komehr (an area near to the
type
locality of the species) with wings having yellow ground colour. All the examined specimens in the present study have pale yellowish-white wings with dark costal strip, nearly a combination of characters of the nominotypical and
sulfuralis
forms. The
type
specimens of this species as well as the
sufuralis
form were not available to be examined. However, it seems that this species has an intraspecific variation in wing’s ground colour and pattern.
FIGURE 13.
A–D) Female genitalia of
Palpita persicalis
(Amsel)
: Main body in ventral view (A), middle part including ostium, antrum and ductus bursae (B, C) and signa (D) (genitalia slides HA-2695, HA-2725, HMIM); the upper and lower arrows in figures B and C indicate finger-shaped and pyramid-shaped processes at the ventral and dorsal sides of ductus bursae, respectively. E, F) Male genitalia of
P. persicalis
: Main
body and phallus in ventral and lateral views, respectively (E) and phallus in lateral view (F) (genitalia slide HA-2418, HMIM).
The genitalia of the examined males are distinctly smaller than that of the females (
Fig. 13A, E
). In addition, the hook-shaped internal process of the valva has a slightly shorter neck (
Fig. 13E
) compared with that of the
holotype
illustrated by
Amsel (1951: 561)
. We believe that the star-shaped end of smaller cornutus in the examined males (
Fig. 13E, F
) compared with the dentate end in the
holotype
, confirms the intraspecific variation of this structure in this species as well.
