## Abstract

Linda (Linda) subatricornis n. sp is described from Sichuan (holotype locality), Fujian, Shaanxi, Hebei, Ningxia of China. It is separated from the most similar species L. atricornis Pic by differences in genitalia and antennal insertions. Detailed descriptions, photographs of habitus and genitalia, distribution of the two sibling species and short discussion on the related species are presented.

## Body

## 1. Introduction

Linda Thomson, 1864 [1], includes two subgenera, Linda and Dasylinda, mostly confined to China [2]. While studying more than 150 specimens of Linda (Linda) atricornis Pic from different localities, we were surprised to observe two very different kinds of male genitalia. We concluded that two superficially similar species have been historically misidentified as one species. We had examined the types of L. atricornis, L. gracilicornis, L. major (the three known species of subgenus Linda with elytra and antennae all black), and most of the other species of this genus. After careful observation and dissection, we separate L. subatricornisn. sp. and herein describe it as new to science.

Elytron slightly emarginate apically, with sutural and outer angles slightly projected. Last visible sternite with a moderate broad and deep groove and apex with a small groove in middle (male, Figure 3(c) and 3(d)) or with a thin line and apex smoothly emarginated (female, Figure 3(h)).Male Terminalia (Figures 4(a)–4(f))
Tegmen length about 3.0 mm; lateral lobes stout, each about 0.5 mm long and 0.25 mm wide, mostly covered with moderate long setae, with one short but broad basal lobe furnished with short setae (in ventral view, Figure4(d)); median lobe plus median struts slightly curved (Figure 4(b2)), a little longer than tegmen (6 : 5); the median struts slightly longer than half of the whole median lobe in length; dorsal plate slightly shorter than ventral plate; apex of ventral plate narrowly rounded (Figure 4(c)); median foramen elongated; internal sac less than twice of median lobe plus median struts in length, with 3 pairs of basal armature, and 2 pairs of rods of endophallus; 2 longer rods each about 1.9 mm, longer than one-half of tegmen, the shorter pair about 0.6 mm. The ratio of short pair to long pair always smaller than 1/3. Tergite VIII (Figure 4(a)) broader than long, apex truncated, rounded at side, with dense but short setae (hairs).Female Genitalia (Figures 4(g)–4(j))
Spermathecal capsule having a strongly sclerotized rounded apical lobe (with a short to long stalk) and a not so sclerotized basal stalk, spermathecal duct not very longer than spermathecal capsule. Spermathecal gland extended from a strongly sclerotized broad ring, which attach to duct directly. Tignum shorter than abdomen. In our observation, tignum 6.8 mm for an adult with a 9.0 mm abdomen in ventral view.Diagnosis
Differs fromL. atricornisby antennal insertions black, extreme bases of tibiae black, groove of last visible sternite of male not so broad, last antennomere longer than tenth antennomere, rods of endophallus slender and the ratio of short pair to long pair smaller than 1/3, lateral lobes stouter, and so forth.
Differs fromL. major and L. gracilicornis by antennal insertions black, femera mostly black, and body not over 20 mm. Differs from all the other species of subgenus Linda by antennae and elytra all black.Etymology
Named after misidentification asL. atricornis in the collections.Remarks
The female genitalia is difficult to separate species. In this species, the stalk attached to the strongly sclerotized rounded apical lobe is quite variable in length (Figure4(h)–4(j)).
L. (L.)gracilicornis m.tatsienluiBreuning, 1954 [13] is a nomen nudum of this species, whileL. (L.)gracilicornism. rufofemorata Breuning, 1954 [13] should be a nomen nudum ofLinda femorata (Chevrolat, 1852).Host (mixed with host ofL. atricornis)

Male (Figures3(a) and 3(b)), length: 13.5–16.0 mm, humeral width: 2.8–3.4 mm. Female (Figure 3(e)–3(g)), length: 15.4–18.5 mm, humeral width: 3.2–4.2 mm. Head (except eyes, antennal tubercles, labrum, and mandibles), prothorax, scutellum, ventral surface of body, basal thirds of femora, and tarsal claws reddish testaceous; antennae, antennal tubercles, elytra, eyes, labrum, mandibles, and most of legs black; pale portions covered with fine silvery pubescence and erect hairs; bases of elytra and undersurfaces of antennae with sparse erect hairs. Head densely and rugulose punctuate; vertex shallowly grooved; antennae shorter than body, about 4/5 (female) to 9/10 (male) of body length, antennomere ratio: male: 13 : 2 : 16 : 14 : 13 : 13 : 12 : 11 : 10 : 9 : 10; female: 15 : 3 : 19 : 16 : 15 : 14 : 13 : 12 : 11 : 10 : 11. Prothorax much broader than long, swollen (three) above and behind middle of each side; scutellum declivitous, truncate. Elytron slightly emarginate apically, with sutural and outer angles slightly projected. Last visible sternite with a moderate broad and deep groove and apex with a small groove in middle (male, Figure 3(c) and 3(d)) or with a thin line and apex smoothly emarginated (female, Figure 3(h)).Male Terminalia (Figures 4(a)–4(f))
Tegmen length about 3.0 mm; lateral lobes stout, each about 0.5 mm long and 0.25 mm wide, mostly covered with moderate long setae, with one short but broad basal lobe furnished with short setae (in ventral view, Figure4(d)); median lobe plus median struts slightly curved (Figure 4(b2)), a little longer than tegmen (6 : 5); the median struts slightly longer than half of the whole median lobe in length; dorsal plate slightly shorter than ventral plate; apex of ventral plate narrowly rounded (Figure 4(c)); median foramen elongated; internal sac less than twice of median lobe plus median struts in length, with 3 pairs of basal armature, and 2 pairs of rods of endophallus; 2 longer rods each about 1.9 mm, longer than one-half of tegmen, the shorter pair about 0.6 mm. The ratio of short pair to long pair always smaller than 1/3. Tergite VIII (Figure 4(a)) broader than long, apex truncated, rounded at side, with dense but short setae (hairs).Female Genitalia (Figures 4(g)–4(j))
Spermathecal capsule having a strongly sclerotized rounded apical lobe (with a short to long stalk) and a not so sclerotized basal stalk, spermathecal duct not very longer than spermathecal capsule. Spermathecal gland extended from a strongly sclerotized broad ring, which attach to duct directly. Tignum shorter than abdomen. In our observation, tignum 6.8 mm for an adult with a 9.0 mm abdomen in ventral view.Diagnosis
Differs fromL. atricornisby antennal insertions black, extreme bases of tibiae black, groove of last visible sternite of male not so broad, last antennomere longer than tenth antennomere, rods of endophallus slender and the ratio of short pair to long pair smaller than 1/3, lateral lobes stouter, and so forth.
Differs fromL. major and L. gracilicornis by antennal insertions black, femera mostly black, and body not over 20 mm. Differs from all the other species of subgenus Linda by antennae and elytra all black.Etymology
Named after misidentification asL. atricornis in the collections.Remarks
The female genitalia is difficult to separate species. In this species, the stalk attached to the strongly sclerotized rounded apical lobe is quite variable in length (Figure4(h)–4(j)).
L. (L.)gracilicornis m.tatsienluiBreuning, 1954 [13] is a nomen nudum of this species, whileL. (L.)gracilicornism. rufofemorata Breuning, 1954 [13] should be a nomen nudum ofLinda femorata (Chevrolat, 1852).Host (mixed with host ofL. atricornis)

## 4. Discussion

Including the new species described above, there are four species of subgenusLinda with elytra and antennae all black. They are Linda atricornis, L. subatricornis, L. gracilicornis, and L. major. L. gracilicornisPic, 1907[17], was described based on one male from Yunnan. The holotype (Figure 5(a1), 5(a2), and 5(a)h deposited in MNHN) is in bad condition, with mud covering the punctures. It is very difficult to conclude if L. majorGressitt, 1942 [18] (Figure 5(b1), 5(b2), and 5(b)h deposited in SYSU) is a synonym of L. gracilicornisor a separate species. In the keys by Gressitt [7, 9, 10], L. gracilicornis “Elytra irregularly punctured; body slender; antennae relatively slender and as long as body,” while L. major “Elytra subregularly punctured, body more or less stout; antennae relatively thick and shorter than body; elytra with round punctures; femora entirely testaceous and length over 20 mm,” descriptions which did not well match with the types. Before enough material are available for further study, we consider them as two different species and L. majordiffers from L. gracilicornis by pronotum quite smooth, without accidented tubercles, elytral punctures denser, and more irregular. One male from Sichuan (Figure 7(a)) and one female from Guangxi (Figure 7(b) and 7(b)h) are identified as L.cf. gracilicornis, while one female from Zhejiang (Figure 7(c)) as L.cf.major according to above consideration. We wait for more material especially specimens from the type localities to make a better conclusion.Figure 5

Scale 2 mm.Based on the holotype (MNHN, ex Coll. J. Thomson, 1952, ex Musaeo ARM. DAVID, 1900),Oberea holatripennis Breuning, 1982 [19], from Beijing (Figure 6(a1), 6(a2), 6(a)h) is similar to L. atricornis but can be separated by the denser and irregular elytral punctures, and the pronotum with three visible swollen. The “paratype” (Figure 6(b1) and 6(b)h,  determined by Breuning, deposited in MHNG, ex Musaeo Arm. David, 1900) is possibly a male of L. atricornis. More material and genitalia dissections are needed for further study.Figure 6
