            <p>Description.</p>
            <p>Male body length 1.93-2.08 mm, width 0.95-1.07 mm; female body length 2.10-2.66 mm, width 1.02-1.32 mm. Body integument black with bronze reflection. Antennomeres I-V and legs yellowish to ferruginous, antennomeres VI-XI piceous. Metafemur black, dorsum with bronze reflection (Fig. 1a, b).</p>
            <p>Head. Vertex impunctate, with weak transverse wrinkles and well-developed supraorbital punctures near orbital sulcus. Antennal callus poorly developed, subtriangular, delimited from vertex by a shallow, barely perceptible groove, surface smooth (Fig. 1c). Orbital sulcus well developed, extending from the top of eye to the antennal socket. Midfrontal and suprafrontal sulci absent. Frontal ridge relatively wide and convex, distance between antennal sockets ca 2.4 times as wide as diameter of antennal socket. Anterofrontal ridge in middle as high as frontal ridge, slightly narrower than frontal ridge. Antennae short, length of antenna ca 0.62 times as long as body length, ratio of length of each antennomere 20: 13: 11: 13: 16: 13: 15: 14: 15: 16: 20. Antennomere II slightly longer than III, as long as IV.</p>
            <p>Thorax. Pronotum 1.33-1.37 times as wide as long. Lateral sides slightly convex, with maximum width in the middle. Anterolateral callosity well developed, slightly lower anteriorly, forming an acute angle. Lateral margin narrowly explanate. Posterolateral callosity low, slightly prominent. Punctures moderately large and dense, distance of interspace 1.5-2.1 times diameter of punctures. Interspaces weakly shagreened, stronger on pronotal disc (Fig. 1d). Scutellum semicircular, widely rounded apically, surface weakly shagreened. Elytra 3.14 times as long as pronotum, with well-developed humeral callus; maximum width in the middle. Apex broadly rounded. Punctures as large as punctures on pronotum but denser, width of interspaces 0.8-1.2 times as diameter of punctures. Interspaces weakly shagreened basally. Hind wings well developed.</p>
            <p>Legs. Metatarsomere I of male 0.54 times as long as metatibia, 1.23 times as long as metatarsomeres II-IV combined. Metatibial spur 0.63 time as long as width of metatibia (Fig. 1a). Tarsal claw simple, without denticle.</p>
            <p>Abdomen. Preapical abdominal tergite of the female with distal area covered by short dense setae, extending forward to the middle at both sides but absent in the middle, sometimes middle area with few long setae. Apical abdominal tergite covered with long setae. A few minute microtrichia situated in the middle and lateral margins (Fig. 3a).</p>
            <p>Male genitalia. Median lobe of aedeagus slightly wider at about apical fourth, apex rounded, without denticle. Ventral side with wide groove which follows shape of entire lobe (Fig. 1e). Apical part dorsally with a subquadrate membranous window (Fig. 1f). In lateral view, the median lobe more or less straight; apical third of aedeagus gradually narrowed towards apex, dorsal side straight, ventral side convex (Fig. 1g).</p>
            <p>Female genitalia. Receptacle of spermatheca slender, 1.92 times as long as wide. Inner side of receptacle convex, outer side nearly straight. Basal part of pump rather long, about as long as apical part, well delineated from receptacle and from apical part of pump; apical part about as long as width of receptacle, narrowly rounded apically. Spermathecal duct forms two loops (Fig. 1h). Tignum slender, slightly curved, dilated apically (Fig. 1i). Vaginal palpus slender, posteriorly straight, narrowly rounded at apex (Fig. 1j).</p>
            <p>Differential diagnosis.</p>
            <p> Longitarsus pekingensis resembles  L. violentus . It can be distinguished from the latter by the lack of sculpture on the vertex. Besides, the median lobe of aedeagus of  L. pekingensis is more or less straight above basal opening in lateral view, without an apical denticle. Receptacle of spermatheca of  L. pekingensis is more slender than that of  L. violentus , and less convex on the inner side; the loops on the spermathecal duct are narrower in diameter. The key below allows to distinguish this species from all other species in the group. </p>
            <p>Etymology.</p>
            <p>The species is named after the type locality. The epithet is a noun in apposition.</p>
            <p>Distribution.</p>
            <p>Known from Changping District and Haidian District in Beijing, China.</p>
            <p>Host plant.</p>
            <p> Bothriospermum chinense Bunge (  Boraginaceae ). </p>

            <p>Abdomen. Distal part of preapical abdominal tergite of female with two subquadrate areas on each side near apical part covered by short dense setae. Apical abdominal tergite covered with long setae. A few tiny microtrichia situated at middle (Fig. 3b).</p>
            <p>Male genitalia. Median lobe of aedeagus in ventral view with sides nearly parallel to each other, apex with poorly developed denticle. Ventral groove wide (Fig. 2e). Apical part dorsally with rectangular membranous window (Fig. 2f). Median lobe narrow in lateral view (Fig. 2g), curved above the basal opening, dorsal side and ventral side both convex apically.</p>
            <p>Female genitalia. Receptacle of spermatheca oval, 1.58 times as long as wide. Inner side of receptacle more convex than outer side. Basal part of pump rather long, about half as long as apical part, well delineated from receptacle and from apical part of pump; apical part longer than width of receptacle, widely rounded apically. Spermathecal duct forms two U-shaped turns (Fig. 2h). Tignum slender, slightly curved, dilated apically (Fig. 2i). Vaginal palpus slender, posteriorly straight, rounded at apex (Fig. 2j).</p>
            <p>Differential diagnosis.</p>
            <p> The key below allows for distinguishing  L. xinjiangensis from all other species in the group. In addition,  L. xinjiangensis is similar to  L. violentus and  L. violentoides . However, the elytra of  L. xinjiangensis are slender, and the punctures on pronotum are larger. Compared to  L. violentus , the antennomeres IV-VI of  L. xinjiangensis are much darker, the median lobe of the aedeagus is broader, and the apex lacks an obvious denticle. Besides, the apex of the spermathecal pump of  L. xinjiangensis is broader than that of  L. violentus , and the spermathecal duct forms two U-shaped turns instead of loops.  Longitarsus xinjiangensis can be distinguished from  L. violentoides by the following characters: antennomere II shorter than IV; aedeagus narrow in lateral view; and apical part of spermathecal pump longer than width of receptacle. </p>
