Redescription of the
lectotype
(male).
Body elongate, almost parallel, convex. Dorsal and ventral surface moderately shiny, brown; macrosetation pale (
Fig. 8
). Dorsal surface of head, pronotum, scutellar shield, and elytra covered with white and pale yellow, short, recumbent scale-like macrosetae; ventral surface of thorax densely covered with pale yellow, long, erect macrosetae; ventral surface of abdomen with densely spaced, white, recumbent, scale-like macrosetae. Head appendages and legs covered with pale yellow, moderately long macrosetae sparsely mixed with white, recumbent, scale-like macrosetae.
Head. Labrum transverse, deeply bilobed, lobes rounded, irregularly and coarsely punctate, covered with long, erect macrosetae and basally with few scale-like macrosetae. Clypeus transverse, rectangular, anterior margin upturned, anterior angles rounded apically. Frontoclypeal suture weakly visible, forming continuous bisinuate flat line. Clypeus and frons densely, irregularly, coarsely punctate; covered with short, erect, scale-like macrosetae; macrosetae mixed on frons with long, erect macrosetae. Eye canthus narrow, with row of short, scale-like macrosetae and few long, erect macrosetae. Eye moderately large, only minutely extending beyond eye canthus. Antenna with 10 antennomeres; antennomere III somewhat longer than antennomeres IV and V combined; club with five antennomeres, shorter than antennal shaft. Antennomere I with long, erect macrosetae apically and laterally; antennomeres II–IV with few isolated, long macrosetae; club with sparse, short macrosetae. Terminal maxillary palpomere elongate, apically rounded, approximately as long as palpomeres II and III combined.

(

. Photograph by Jan Šumpich, June 2017.
Pronotum transverse, moderately convex with distinct longitudinal groove in the middle, widest approximately in the middle. Basal border present, broadly interrupted in the middle, lateral borders complete, anterior border missing. Lateral margins weakly crenate. Anterior margin regularly, broadly sinuate. Anterior angles obtuse-angular; posterior angles broadly rounded. Punctation consisting of coarse, irregularly-spaced punctures becoming denser in the longitudinal groove, each puncture bearing white, scale-like, recumbent macroseta; two rounded, impunctate, bare lateral areas on each side of pronotum present.
Scutellar shield large, transverse, sides and apex broadly rounded; disc punctate
laterally, densely covered with white, scale-like, recumbent macrosetae.
Elytra convex, parallel sided, rounded apically; apical angle obtuse-angular. Striae missing; humeral umbones present, vaguely swollen. Surface moderately shiny; punctation coarse, irregularly spaced. Each puncture bearing short, white, scale-like, almost recumbent macroseta. Epipleura narrow, with several macrosetae in basal third.
Macropterous.
Legs. Femora narrow, shiny, irregularly punctate; densely covered with long, semierect, pale yellow macrosetae mixed with short, white, recumbent, scale-like macrosetae. Protibia narrow, tridentate, terminal calcar missing. Mesotibia and metatibia slightly expanded apicad, with two macrosetiferous longitudinal and two incomplete oblique transversal carinae, sparsely covered with short scale-like macrosetae, inner part densely covered by long erect macrosetae. Upper terminal calcar of metatibia flattened, blunt apically, about 1.5 times as long as lower calcar. Tarsal claws bifid, with well-developed, unequal ventrobasal teeth. Protarsus with distinctly longer ventrobasal tooth of inner claw, whereas mesotarsi and metatarsi with more robust ventrobasal teeth on outer claws.
Ventral surface of thorax densely covered with pale yellow, long, erect macrosetae; ventral surface of abdomen with densely-spaced, white, recumbent, scale-like macrosetae.
Pygidium almost flat, completely bordered; apically broadly rounded; irregularly covered with coarse punctures bearing short, recumbent, scale-like macrosetae.
Male genitalia. Parameres symmetrical, two times as long as phallobasis (
Figs. 3–4
).
Sexual dimorphism.
Female (
Figs. 5–6
) differs from male in the following characters: pronotum dark brown to black; clypeus broadly rounded; antennal club with four antennomeres, shorter; terminal calcar of protibia present (
Fig. 7
); tarsal claws of all legs with ventrobasal teeth equal.
Variability.
In comparison with
lectotype
, recently collected male from “Vordan Karmir” State Sanctuary has partially abraded scale-like macrosetae on pronotum and protibia, as well as external teeth on protibia.
Measurements.
Total body length of males:
22.1–22.5 mm
(
lectotype
22.1 mm
), females:
21.4–21.8 mm
.
Diagnosis.
An examination of both sexes helps us to clarify the generic placement of the species. The presence of terminal calcar of protibia in the female, its absence in the male, and the length of antennomere III clearly place this species in the genus
Anoxia
. The rounded apex of the pygidium more precisely place it in the subgenus
Protanoxia
. Therefore, the following combination is proposed:
Anoxia
(
Protanoxia
)
maljuzhenkoi
(
Zaitzev, 1928
)
,
new combination
.
Previously, eight members of
Protanoxia
were known (

,
1992
,

). Two of them,

form a trio of habitually similar and rarely collected species, the males of which are characterized by an antennal club as long as the antennal shaft and by the presence of three external teeth on the protibia. Males of other
Protanoxia
species differ from this trio in displaying an antennal club that is distinctly longer than the antennal shaft (

Collecting events.
All recently recorded specimens from Arazap were collected by light trap (J. Šumpich and A. Pavlíčko, personal communication). The biotope, where the specimens were collected, is very specific (
Fig. 17
). According to the European Nature Information System habitat classification (
Davies
et al.
2004
), it belongs to the category
E6.2
. (continental inland salt steppes), habitats completely included in Resolution 4 of the Bern Convention as specifically protected. The particular biotope belongs to the subcategories
E6.25
-AM (salt steppes and solonchaks grasslands) and
E6.251
-AM (
Aleuropus
(
Poaceae
) dominated habitats) (
Fayvush & Aleksanyan 2016
). The latter being one of the few remained spots of this
type
of habitat and it is protected as a biotope of the critically endangered Araratian cochineal or Vordan karmir –
Porphyrophora hamelii
(Brandt, 1833)
(
Hemiptera
: Margarodi- dae).
