DESCRIPTION. MALE ( Figs. 11–12 ). Length from the tip of mandibles to the apex of elytra 8–9.5 mm, humeral width about 2 mm. Body black, appendages reddish-brown except swollen part of femora, head reddish-brown except between the eyes; elytra partly in basal third, centrally and widely in apex also reddish-brown.

Antennae with appressed whitish pubescence, segments 7–9 almost completely, the other segments only basally. Elytra with three whitish fasciae as follows (elytra under fasciae generally reddish-brown): from scutellum along the suture to 1/5 of the length and bent outwards to the lateral margin, broad median one from suture reaching almost lateral margin with unclear delimitation, preapical one. Most of the

13, 14 – female paratype: 15–18 – A. vicinulus Holzschuh, 1999: 15 , 16 – male from Shaanxi;

17, 18 – female from Beijing. Scale bar = 1 mm.

pronotum covered with appressed whitish pubescence, dense and long at sides and underside, rather sparse on the disk but often forming clear transverse hairless spot in the middle (i.e., black). Underneath the body also with appressed long dense whitish pubescence.

Head short, with well developed, widely separated antennal tubercles; across the eyes almost as wide as pronotum at its widest point. Antennae relatively long,

slightly extend the apex of elytra; all segments of normal length of the genus – 2nd

segment is the shortest, but apparently longer than broad; 3rd segment longer than the following two (1.5 x 4th, 1.15 x 5th), about as long as 6th or 7th. Apical part of antennal segments with inner spines as follows: 3rd segment with relatively long spine, 4th segment with very short spine, no spine apparent at 5th segment. Scapus moderately thickened with clear punctures.

Pronotum barely longer than wide; rounded at sides, widest in apical third, apparently narrowed basally, constricted; flat (longitudinally) on top of the disc, sharply decreasing only at base.

Scutellum triangular, with short pubescence.

Elytra about 2.5 times as long as humeral width; regularly narrowing to apices;

each apex truncated, but with long outer tooth and indistinct inner spine; with relatively dense punctures.

Legs of normal size of the genus in relation to the body, metafemora does not reach elytral apices, all femora claviform; 1st segment of hind tarsi 1.35 times as long as following two combined.

Male genitalia as in Figs. 25–29 . Median lobe arcuate in lateral view ( Fig. 28 );

ventral plate sharply narrowed to apex ( Fig. 27 ); median struts long and relatively broad, extends for more than one half of median lobe. Tegmen much shorter than median lobe; parameres very short and wide, apically rounded, broadly separated,

with many short setae and a few long setae at apex, long setae more than twice of parameres in length; ringed part extends for more than 3/4 of tegmen, rounded in the widest portion, converging at apex. Tergite VIII ( Figs. 25–26 ) transverse, largely rounded from base to apices, apex slightly emarginated, clothed with short erect setae.

FEMALE ( Figs. 13–14 ). Length from the tip of mandibles to the apex of elytra

8–10 mm, humeral width about 2 mm. Elytra preapically much wider than in male.

Antennae shorter than body. Color without any distinct differences from males.

DIFFERENTIAL DIAGNOSIS. The new species belongs to the group of reddish-brown species with white transverse fasciae on elytra and rather rounded pronotum, A. kanssuensis Ganglbauer, 1889 group, within which it belongs to subgroup A (alphabetically).

Subgroup A. Apex of elytra reddish, preapical whitish fasciae.

1) A. confusus Holzschuh, 1999 – described from Xizang; a larger species with much longer elytra with different kind of pubescence, which is not so light, convex pronotum with a postmedian keel and relatively long spine at 3 rd antennal segment.

2) A. rufobasalis Tippmann, 1955 – currently in subgenus Aglaophis , described from Fujian; probably the smallest species of the group, apparently differs by longer spine at 3rd antennal segment, slightly longer and less rounded pronotum with clear keel in the middle, generally reddish base of elytra without black areas,

postbasal fasciae of whitish pubescence and reddish-brown elytral marking rather straight (not curved as in the new species).

3) A. vicinulus Holzschuh, 1999 ( Figs. 15–18 ) – known from Gansu and Sichuan in the west to Beijing and Henan in the east; the most similar species by colour; it differs through the pronotum, which is more globular, convex on top, highest just before base with apparent keel in A. vicinulus , while almost flat on top and sharply going down at base in the new species; more rounded at sides in A. vicinulus , while little more straight in the new species; with rather four separated hairless spots on disc of pronotum in A. vicinulus , while with apparently long appressed whitish hairs in the new species, especially in apical third and thus often with contrasting transverse black fasciae. Basal part of elytra with strongly elevated tubercles (not so apparent in the new species); not so oval body; different orientation of pubescence at sides and underside (apparent especially at pronotum – rather transverse in A. vicinulus ,

while mostly longitudinal in the new species); different genitalia as in Figs. 19–24

(parameres generally short, but longer and narrowly separated when compared to the new species; apex of dorsal plate of median lobe ( Fig. 21 ) much less protruding compared with the new species ( Fig. 27 ); tergite VIII ( Figs. 19–20 ) in comparison to the new species almost parallel at sides and relatively shortly rounded in apices,

with apparent emargination).

Subgroup B. Apex of elytra largely light (grayish to whitish).

4) A. gressitti Holzschuh, 1999 – a species which can be also very small; with apical part of elytra widely covered by whitish pubescence and longer antennae with apparent spine at 3rd segment.

5) A. kanssuensis Ganglbauer, 1889 – widely greyish apex of elytra, rather globular pronotum and less oval body; spine at 3rd segment of antennae rather short.

6) A. petrae Viktora et Liu, 2018 – the only other species of this group known from Yunnan; it easily differs due to apex of elytra fully covered by whitish pubescence, larger size, longer elytra and dark appearance – elytra are missing reddishbrown parts, antennae are completely dark, legs mostly (except basis of femora)

black.

7) A. producticollis Gressit, 1951 – currently in subgenus Aglaophis , greyish elytral apices and globular pronotum as in A. kanssuensis ; long spine at 3rd antennal segment and relatively dark appearance (dark antennal segments 1 to 6 and legs).

8) A. tersus Viktora et Tichý, 2015 – antennae much longer than body in males,

pronotal pubescence forming two large dark spots and quite different elytral pubescence – besides three dirty white and rather broad and strait transverse bands

(posthumeral, postmedian and preapical) it has also humeral and rather isolated median spots; no black areas.

Further species known from Yunnan and Xizang provinces have either robust yellowish to green body with blackish isolated spots or clearly demarked transverse fasciae ( A. annulicornis (Pic, 1933) , A. flavus Viktora, Tichý et Rapuzzi, 2013 , A.

tichyi Miroshnikov, Bi et Lin, 2014), robust, rounded reddish-brown body with isolated dark brown spots ( A. ambiguus Holzschuh, 1992 ), or prolonged body (and pronotum) with very different pubescence ( A. arcanus Miroshnikov, Bi et Lin,

2014, A. elegantulus Miroshnikov, Bi et Lin, 2014 , A. qijuni Viktora et Liu, 2018 ).

BIONOMY. Most of the specimens were collected on flowering Viburnum sp.

together with Ischnostrangalis ohbayashii sp. nov.

DISTRIBUTION. China (Yunnan).

ETYMOLOGY. Named in honor of Mr. Alexandr Miroshnikov (Krasnodar,
