Specific epithet.
Feminine adjective, from the Latin
solitarius, -a
(lonely), which indicates that this new species is known from a single individual only, flying at night.

Diagnosis.
With the character states of the genus
Calleida
in the narrow sense, but characterized by the peculiar combination of the following morphological features: small-medium sized (TL: mm 7.1); body brown, darkened on head and disc of pronotum; antennae, tibiae, tarsi, and abdominal segments rufous. Pronotum cordiform; elytra elongate, depressed, beaded at apex, with deep and deeply punctate striae. Abdominal sternum VII with one seta on each side in males. Male genitalia as in Fig.
8
. Female unknown.
Description.
General features as in Fig.
4
. Small-medium sized: L: 7.6 mm; TL: 7.1 mm.
Color
: head dark brown, without reddish spots on frons; antennomeres dark rufous. Prothorax and pterothorax brown; pronotum dark reddish at sides. Elytra brown, with slight metallic bronze reflection; tibiae, tarsi, and abdominal segments dark rufous.
Luster and microsculpture
: head and pronotum moderately glossy, with generally effaced cuticular microlines, hardly visible as reticulate meshes; elytra moderately glossy, with cuticular microlines evident in form of transverse pattern.
Head
: wide, transverse, with evident, deep neck constriction; genae very swollen, contiguous with the posterior margin of eyes; frontal furrows deep, connected posteriorly with the supra-orbital keels; eyes very large and prominent; two supraorbital setae on each side.

idem, head and pronotum.
Prothorax
: transverse-cordiform (ratio PL/PW: 8.82), with lateral margins moderately sinuate in the posterior third and constricted to the base. Lateral furrows narrow, punctate; lateral reflection slight. Disc convex, with superficial transverse wrinkles. Median furrow deep, reaching the posterior margin. Anterior angles rounded, not prominent; basal angles obtuse but evident. Base almost straight, beaded. One paramedial seta and one basolateral seta on each side present.
Elytra
: elongate (ratio EL/EW: 1.8), depressed, slightly widened at the apical third; striae deep, deeply punctate; intervals slightly convex. Post-humeral sinuation inconspicuous, pre-apical callosity absent. Apex beaded, oblique, with the outer angle fully rounded and sutural angle prominent. Interval 3 with two discal and one apical setiferous puncture; umbilicate series of 14 large foveate punctures along stria 8, widely interrupted in the middle.
Hind wings
: fully developed.
Legs
: slender. Metatarsomeres 1-3 superficially grooved dorsally; metatarsomere 4 deeply bilobed, its lobes long and narrow. Tarsal claws denticulate, each with five long teeth on the inner side.
Abdominal sterna
: sternum VII with one seta on each side in males (unknown, but probably two setae on each side in females).
Male genitalia
: median lobe of aedeagus (Fig.
8
) very elongate and slender, with basal lobe markedly differentiated. Endophallus with a long flagellum, twisted at base.
Female genitalia
: unknown.
Geographical distribution and habitat.
Known so far from the type locality only. It is probably a nocturnal forest-dwelling species at lower altitudes. The single male individual of this taxon was obtained in October, at the lights of the Biolab in Pakitza.
Relationships.
For its basic morphological features of shape, size, and characters of the median lobe of aedeagus and endophallus, this species seems to be close to the species of the
cordicollis
(=
decora
) species group in the sense of Casale in
Desender et al (2002)
, from which it is markedly distinct by the different pattern of color on the dorsal side (mostly metallic in the
cordicollis
group), and by the different number of setae on the abdominal sternum VII (two in male in
C. solitaria
, three in species of the
cordicollis
group).
