Neuraphes (Paraphes) gomarantsus MEYBOHM View in CoL spec. nov.

( Figs 60–62 View Figs 57–65 )

Type material: Holotype: “ ARMENIA [30] – 25 km S Kapan, Gomarants Ps. , 39°01'32"N, 46°21'59"E, 2190 m, oak forest, 7.VII.2016, V. Assing / Neuraphes gomarantsus m. Meybohm 2018 det. / Holotypus ” (cMey) GoogleMaps . Paratypes: 2: same data as holotype (cMey); 1: “ARME- NIA [31] – 25 km S Kapan, Gomarants Ps. , 39°02'15"N, 46°22'13"E, 2050 m, oak forest, 7.VII.2016, V. Assing ” (cMey) GoogleMaps .

Etymology: The specific epithet is an adjective derived from Gomarants Pass, the type locality.

Description: Body length 1.80–1.85 mm. Body unicoloured reddish-brown, glossy. Palpi, antennae, and legs light-brown. Pubescence bright, long, and sub-erect; setae about as long as antennomere II. Male habitus as in Fig. 60 View Figs 57–65 .

Head 0.28 mm long and 0.29 mm broad; occipital constriction about three-fourths as broad as head; vertex convex, with a pair of large, very shallow impressions located between the eyes and delimiting a median trapeziform flat area; supra-antennal tubercles marked, temples pronounced, half as long as diameter of eyes; eyes large, in female weakly convex and coarsely faceted, in male more convex and more distinctly faceted.

Antennae in 0.84–0.91 mm long, antennomere I twice as long as broad, II distinctly narrower and slightly shorter than I, twice as long as broad, III and IV distinctly narrower than II and much shorter, 1.5 times as long as broad, V slightly broader and longer than III and IV, VI as broad as V, as long as III and IV, 1.3 times as long as broad, VII much broader than VI, 1.2 times as long as broad; VIII–X (measured without apical conical part): VIII broader than VII, as long as broad, IX broader than VIII, slightly broader than long, X broader than IX, 1.4 times as broad as long, XII slightly shorter than IX–X combined. Antennae in male distinctly longer and more slender than in female, 0.98 mm long, III–V 1.7 times as long as broad, VI much broader than V, but of equal length, XII much shorter than IX–X combined.

Pronotum elongate in dorsal view, 0.45 mm long and 0.39 mm broad, broadest at anterior third, lateral margins strongly rounded in anterior third, distinctly converging in posterior half and slightly concave near the almost rectangular hind angles. Posterior margin weakly arcuate; base with a transverse groove, ending laterally in a shallow depression, medially interrupted by a short longitudinal carina, on both sides of the carina with a large impression; punctures very fine.

Elytra oval, broadest at anterior third, length 1.11 mm, width 0.68 mm; humeral calli marked, forming elongate, longitudinal folds; basal pit on each elytron moderately large, closer situated to scutellum than to humerus; apices of elytra separately rounded; punctures in antero-sutural portion fine and similar to those of head, otherwise coarser; interstices slightly narrower than length of setae.

: elytra ( Fig. 61 View Figs 57–65 ) subapically near suture with weak longitudinal elevation, this elevation apically with pit of circular shape separated from the elytral posterior margin by its diameter and from the suture by half its diameter; diameter of this pit equal to width of antennomere VI; anterior margin of this pit with sparse short and straight setae; apical portion of elytra with some long setae directed posteriad. Metaventrite medially with a large and oblong oval impression; impressions not delimited by an elevation and with dense, weakly erect pubescence directed posteriad; pubescence of lateral portions sparser, more erect, and directed obliquely postero-laterad.

Aedeagus 0.35 mm long and 0.19 mm broad; shaped as in Fig. 62 View Figs 57–65 ; vestigial parameres distinct, not reaching middle of median lobe; large sclerites bent dorsad apically in lateral view; the four lobes of distal sclerite of similar size.

Comment: One female not included in the type series, but collected together with the holotype, differs from the type specimens by blackish body, shorter antennae (0.84 mm), shorter elytra (1.04 mm), and the shape of the pronotum. It most likely belongs to a different species.
