Description.
Adult (
Fig. 1
). Wingspan
11 mm
. Labial palpus narrow, short, slightly curved, covered with bronze scales on ventral side, and with silvery-grey on dorsal side, tip of third segment brown. Head and frons bronze with metallic shine. Forewing costa, dorsum, basal, apical and subapical areas brown, interspace in middle of wing light orange. Three dark spots with several silver scales in postbasal, tornal, and discal areas. Fringe and hindwing uniform chocolate brown, same shade as brown parts of forewing.

Molecular data.
BIN URI not stated previously. Process ID in BOLD: DEEUR1078-17. According to the phylogenetic tree,
C. karsholti
is sister to the genetically very close
C. germanica
with only 1,10 % difference between them (see
Fig. 5
and
Table 1
). These two species are sister to
C. gabretica
with genetic distances of 7.86 and 7.96 % respectively.

Diagnosis
.
Chrysoclista karsholti
resembles
C. gabretica
; the orange scales of the forewing of the latter are of the same shade as those of
C. karsholti
, but in
C. gabretica
the orange area reaches the dorsal margin (terminating before the margin in
C. karsholti
). Also, there is a conspicuous basal dark logitudinal streak in
C. gabretica
that is indistinct in
C. karsholti
.
The genitalia of these two species are very similar but the valvae are rounded in
C. gabretica
,
whereas they are distinctly elongated dorsoventrally in
C. karsholti
. The shape of the anellus lobes are distinct in both species.
Chrysoclista karsholti
is also similar to
C. germanica
, but in the latter species the orange area is red-orange, and the brown colour is darker. In the male genitalia, the main differences are the shapes of the valvae (much more elongated in
C. germanica
), and the size and number of spines in the terminal part of ther phallus (smaller and fewer in
C. karsholti
).
Chrysoclista karsholti
is closely related to
C. germanica
based on the DNA barcode sequences. We cannot exclude the presence of cryptic diversity in this genus as was indicated by
Šumpich & Huemer (2016)
in which a similar dataset was interpreted in detail. For a clarification of this problem, additional material for genetic and morphological analysis is needed. Because the description of the new species is based on a single specimen, it is possible that
C. karsholti
merely represents variation with
C. germanica
. However, evidence from forewing pattern and genital morphology suggest otherwise.
Distribution
. The species is known only from
Turkey
.
Bionomics.
The early stages are unknown. The adult was collected in July. The exact collecting locality of the
holotype
is unknown - Kizilcahamam is located in an area with altitudes between
1000 m
and
1400 m
.
Etymology.
The name of the new species is a patronym for Ole Karsholt, who has contributed significantly to the research of gelechiioid moths, including
Chrysoclista
species.
