3.1. Taxonomy
Telsimia scymnoides Miyatake, 1978: 15 [
23]; Yu, 1995: 141 [
35]; Ren et al., 2009: 152 [
39].
Diagnosis. This species can be easily distinguished from other
Telsimia species by its unique coloration: head and pronotum entirely brownish yellow; elytra black, each elytron with a large, oblique, oval, brownish yellow spot at apical half, reaching lateral margin, suture, and apex (
Figure 1a–c). It can also be diagnosed by its male genitalia: in ventral view, base of penis guide is nearly the same width as phallobase, slightly convergent to apical one-fifth, then suddenly narrowing to a bifid apex (
Figure 1j).

Biology. Unknown.
Etymology. The specific epithet refers to its general appearance and penis guide closely resembling T. scymnoides Miyatake.
Diagnosis. In male genital structure, this species is most closely related to
T. scymnoides but can be easily distinguished from the latter by detailed characteristics of penis guide: in ventral view, penis guide slightly convergent to apical one-sixth, then relatively smoothly narrowing to the apex, which is protruding and arcuate, with a tiny notch at middle (
Figure 2g), while in
T. scymnoides, penis guide slightly convergent to apical one-fifth, then suddenly narrowing to a bifid apex (
Figure 1j).

Etymology. The specific name refers to the locality of its holotype.
Diagnosis. In external appearance, it is similar to
T.
parascymnoides sp. nov., with the head, pronotum, and elytra terminal brownish yellow (
Figure 4a–c), but can be easily distinguished from the latter by the male genitalia (

T.
shirozui but can be distinguished from the latter by the following characteristics: in ventral view of tegmen, base of phallobase half the width of proximal end, apical emargination of penis guide larger, inverted U shape; in
T.
shirozui, base of phallobase slightly narrower than proximal end, apical emargination smaller, inverted V shape. In lateral view of tegmen, penis guide thick, nearly parallel for the basal two-thirds, apical part sharper; in
T.
shirozui, penis guide relatively thinner, gradually narrowing to apical one-fourth, apical part blunt.

Biology. Unknown.
Etymology. The specific epithet is the Latin adjective “latus”, meaning broad, referring to its broad penis guide in ventral view.
Diagnosis. Male genitalia of this species are similar to
T.
daclacensis Hoàng, 1983 with proximal end of penis guide in ventral view distinctly stretched out laterally. The difference is, in
Telsimia latus, the outline of the protruding part on each side is similar to an arc (
Figure 5g), while, in
T.
daclacensis, the protruding part on each side forms a downward projection (Hoàng 1983, p.7,
Figure 2).

Body oval, convex, broadest at middle; above black except anterior corners of pronotum and head brownish yellow (
Figure 5a–c); underside dark brown to black, except elytral epipleuron brownish yellow, mouthparts, prothoracic hypomeron, and legs brownish yellow. Head between eyes nearly 0.4 times the width of head; pubescence dense, appressed, and silver-white. Pronotum slightly more than twice as broad as median length; anterior border arcuate medially, distance between anterior angles 0.6 times that between posterior angles, lateral borders arcuately convergent from obtuse posterior to briefly rounded anterior angles; pubescence dense, suberect, and silver-white. Elytra slightly shorter than greatest combined breadth; external margins not or very slightly explanate to borders; pubescence dense, suberect, and silver-white. Abdominal postcoxal lines of ventrite 1 slightly recurved, punctures between coxae small and sparse; ventrite 5 in midline as long as ventrites 2–4 together, apical border briefly notched medially in male (
Figure 5d).

Remarks. This species is recorded in China for the first time. The female genitalia of this species are also provided for the first time.
Biology. Unknown.
Etymology. The specific epithet is the Latin adjective “lunata”, meaning crescent-shaped, referring to the crescent stripe on elytra.
Diagnosis. This species can be easily distinguished from all known
Telsimia species by its unique elytra markings, as shown in
Figure 7. The male genitalia are similar to
T.
postocula but can be distinguished by detailed characteristics of tegmen in ventral view: penis guide slightly longer (1.2×) than phallobase and apical notch inverted V-shaped in
T. lunata (
Figure 7j); in
T.
postocula, penis guide distinctly longer (1.8×) than phallobase and apical notch nearly fusiform (Kapur 1967, p.169,
Figure 7b).
Description. TL: 1.38–1.76 mm, TW: 1.10–1.36 mm, TH: 0.60–0.80 mm, PL: 0.36–0.52 mm, PW: 0.84–0.96 mm, HW: 0.50–0.64 mm, ID: 0.18–0.24 mm, TL/TW: 1.25–1.32, PL/PW: 0.43–0.60, EL/EW: 0.84–1.05, HW/PW: 0.54–0.67, PW/EW: 0.71–0.79, ID/HW: 0.33–0.40.

Abdominal postcoxal lines of ventrite 1 not recurved, punctures between coxae small and sparse; ventrite 5 in midline distinctly shorter than ventrites 2–4 together, apical border briefly notched medially in male and evenly arcuate in female (
Figure 7d,f).
Male genitalia: Penis distinctly stout except basal one-third relatively slender, slightly curved at middle part, apex rounded in lateral view (
Figure 7g). In ventral view, penis broadest at middle part, apex bifurcated (
Figure 7h). Penis guide in lateral view thick, almost parallel at basal two-thirds, then inner side directly narrowing to outside, forming a blunt apex; tegminal strut extremely short (
Figure 7i). Penis guide slightly longer than phallobase. Parameres distinctly shorter than penis guide, apex with several long setae. Penis guide in ventral view, 1.60 times as long as wide, nearly parallel for basal two-thirds, apex bifid with a large, inverted V-shaped notch (

Biology. Unknown.
Etymology. The specific epithet is the Latin adjective “parvus”, meaning small, referring to its small penis guide in ventral view.
Diagnosis. In external appearance, it is similar to
T.
forcipata sp. nov., for the short oval body, narrower interocular distance (less than one-third the head width), and dense, gold pubescence on head (
Figure 9a–c), but their male genitalia vary greatly (
Figure 9e–h and
Figure 10g–j). In male genital structure, this species is most closely related to
T. jinyangiensis, but can be easily distinguished from the latter by some detailed characteristics: in
T. parvus, basal part of penis slender, without any subsidiary structure (
Figure 9e); tegminal strut very short, nearly one-tenth the length of tegmen (
Figure 9g); phallobase 1.2 times the length of penis guide; apical emargination of penis guide is small and deep, the depth is five times the width of the opening (
Figure 9h); in
T. jinyangiensis, basal part of penis with a broad handle-like structure; tegminal strut short, nearly one-fifth the length of tegmen; phallobase nearly the same length as penis guide; apical emargination of penis guide is short triangular, the depth is three times the width of the opening.
Description. TL: 1.60 mm, TW: 1.36 mm, TH: 0.92 mm, PL: 0.46 mm, PW: 0.92 mm, HW: 0.56 mm, ID: 0.16 mm, TL/TW: 1.18, PL/PW: 0.50, EL/EW: 0.96, HW/PW: 0.61, PW/EW: 0.68, ID/HW: 0.29.
Body short oval, convex, broadest at middle; above entirely black; underside dark brown to black, except elytral epipleuron orange-brown, mouthparts and legs brownish yellow. Head between eyes narrow, nearly 0.3 times the width of head; pubescence dense, appressed and gold. Pronotum twice as broad as median length; anterior border arcuate medially, distance between anterior angles 0.6 times that between posterior angles, lateral borders arcuately convergent from obtuse posterior to briefly rounded anterior angles; pubescence dense, suberect and gold. Elytra slightly shorter than greatest combined breadth; external margins not or slightly explanate to borders; pubescence dense, suberect, and silver-white. Abdominal postcoxal lines of ventrite 1 recurved, punctures between coxae small and sparse; ventrite 5 in midline as long as ventrites 2–4 together, apical border distinctly notched medially in male (
Figure 9d).
Male genitalia: Penis robust, in lateral view, basal half gradually narrowing from the middle to distal end, as long as the tegmen; apical half slightly narrowing to a rounded apex (
Figure 9e). In lateral view of tegmen (
Figure 9g), tegminal strut extremely short, nearly one-tenth the length of tegmen; phallobase 1.2 times the length of penis guide; penis guide thick, thickness almost three-fourth the width of penis guide in ventral view, gradually narrowing from base to apical one-third, then inner side suddenly convergent to a blunt apex; parameres robust at basal two-fifth and slender at apical three-fifth, with several long setae at apex, as long as penis guide. In ventral view of tegmen, the phallobase nearly rectangle, the ratio of width to length is about 3:4; base of penis guide nearly 0.65 times the width of phallobase, penis guide slightly convergent to apical one-third, then gradually narrowing to a bifid apex, the apical emargination small and deep, the depth five times the width of the opening (
Figure 9h).
Female genitalia: Unknown.
Types. Holotype: ♂, China: Guangxi Prov.: Shiwandashan National Forest Park, Hongqi Forest Farm, 11.XI.2004, Zhang CW leg, No. 20051211229, SCAU(E)16742.
Distribution. China: Guangxi.
Biology. Unknown.
Etymology. The specific epithet is the Latin adjective “forcipata”, meaning forcipate, referring to its forcipate penis guide in ventral view.
Diagnosis. Penis guide of this species in ventral view is deeply bifid (
Figure 10j), which is similar to
T.
ismayi (Chzeau 1984, p. 4, pl. II-4) and
T.
nigra (Weise). However, in the last two species, there is a distinct triangular protrusion on each lateral side at apical one-third of penis guide, which can be easily distinguished from
T.
forcipata.

Pronotum approximately twice as broad as median length; anterior border arcuate medially, distance between anterior angles 0.6 times that between posterior angles, lateral borders arcuately convergent from obtuse posterior to briefly rounded anterior angles; pubescence dense, suberect, and silver-white. Elytra slightly shorter than greatest combined breadth; external margins not or very slightly explanate to borders; pubescence dense, suberect, and silver-white. Abdominal postcoxal lines of ventrite 1 recurved, punctures between coxae large and sparse; ventrite 5 in midline as long as ventrites 2–4 together, apical border flattened medially in male and evenly arcuate in female (
Figure 10d,f).
Male genitalia: Penis thick, curved at middle part, apex rounded, as long as the tegmen (
Figure 10h). Tegminal strut stout, broad at basal part, as long as phallobase (
Figure 10j). Parameres distinctly longer than phallobase and slightly shorter than penis guide, apex with several long setae. Penis guide in lateral view thick, nearly parallel at basal two-thirds, then narrowing to blunt apex (
Figure 10g). Penis guide in ventral view forcipate, splitting upward from apex to basal one-fourth (
Figure 10j).

Distribution. China: Fujian, Jiangxi, Henan, Hunan, Guangdong, Guangxi, Sichuan, Yunnan, Shaanxi, Taiwan; Japan.
Remarks. Pang and Mao [
33] described a new subspecies according to one specimen from Sichuan Province and explained its difference from that of Japan by the angulation on the lateral side of each lobe and the depth of the split. We compared 11 male specimens from five provinces (including Sichuan Province, the type locality of this subspecies) (
Figure S1), and we did not find any significant differences from Sasaji’s illustrations [
26] (p.214, Figure 88).
Biology. This species is reported to prey on
Aulacaspis rosarum Borchsenius,
Unaspis yanonensis (Kuwana),
Aphis citricidus (Kirkaldy), and
Lepidosaphes tubulorum Ferris [
7,
50,
51,
52].
Telsimia darjeelingensis Kapur, 1969: 50 [
25].
Diagnosis. Male genitalia of this species resemble
T.
ceylonica Kapur 1969, but can be easily distinguished from the latter by the following characteristics: in
T. darjeelingensis, tegminal strut slightly longer than penis guide; penis guide gradually narrowing to a bifid apex (
Figure 13g); basal part of penis with membranous appendages, preapical part of penis slightly enlarged but the apex curved and acute (
Figure 13e); in
T.
ceylonica, tegminal strut distinctly shorter than penis guide; penis guide gradually narrowing to a blunt apex; basal part of penis without membranous appendages, apex of penis bulbous, nearly dumbbell-shaped (Kapur 1969, p.47,
Figure 1).
Material examined (1). 1♂, China: Yunnan Prov., Gaoligong Mountains, 19.IX.2006, Wang XM leg., SCAU(E)16771.
Distribution. China: Yunnan; India.
Remarks. This species is recorded in China for the first time.
Biology. Unknown.
Etymology. The specific name refers to its type locality.
Diagnosis. In male genital structure, this species is closely related to
T. emarginata and
T.
abdita Ślipiński, Pang and Pope, 2005, but can be distinguished from the latter by some detailed characteristics: basal one-fourth of the penis thread-like, apical one-fourth gradually narrowing to a blunt apex (
Figure 15i); in the latter two species, penis tubular, thickness almost consistent in the whole length, except the apical part slightly narrowing to a rounded apex (
Figure 11g). Tegmen is mostly similar to
T.
abdita, but can be distinguished from the latter by detailed characters of penis guide: in lateral view, the apex bent inward (
Figure 15h), while, in
T.
abdita, the apex bent outward; in ventral view, the apex is truncate, with a median line (
Figure 15i), while, in
T.
abdita, the apex is rounded, without a median line.

Biology. Unknown.
Etymology. The specific epithet is the Latin adjective “lobatus”, meaning lobed, referring to the bifid apex of penis guide in ventral view.
Diagnosis. This species can be easily distinguished from all known
Telsimia species by its male genitalia: penis distinctly stout (
Figure 16f), penis guide in ventral view broad, 2.5 times of length than width, parallel at basal two-thirds, then gradually narrowing to a very small bifid apex (
