Diagnosis: Similar to L. decempunctata but with 6 black spots on the scutellum, and distinguished by the following characters: Lateral angles of pronotum more strongly protuberant, posterolateral margin of pronotum with the basal half distinctly concave, and the apical conjunctival lobe of aedeagus not bifurcate apically as in L. decempunctata .

Description: Color: Dorsum ochraceous, with black or brown punctures; head, pronotal lateral angles, and connexiva testaceous. Apical margin of scutellum pale yellow and smooth. Body beneath yellow with coarse and concolorous punctures. One black spot near coxa on inner side of each thoracic pleura, and another black spot at anterior margin of each mesopleura. Legs yellow brown,except for black apices of claws.

Head: Long, with a levigate patch near each eye. Mandibular plates wide, convergent before clypeus or leaving a gap. Antennae with 1st to 3rd segments and extreme base of 4th yellow brown, other part of 4th segment and all of 5th one black; 2nd shorter than 3rd. Apex of rostrum black and reaching to posterior limits of metacoxae.

Thorax: Pronotum: 4 black spots arranged equidistantly in a nearly transverse line medially; anterior margin roundly excavated; anterior angle short, sharp at apex and pointing forwards; anterolateral margin strongly concave, coarsely and whitely dentate; lateral angle robustly produced, then bent forwards, apex of this passing beyond anterior limits of eyes; an obtuse tubercle at posterior margin of each lateral angle; posterolateral margin of pronotum with basal half distinctly concave; posterior margin straight. Scutellum: 6 black spots at base, 4 of which linearly along basal margin, other 2 arranged behind medially; apex of scutellum bluntly rounded and distinctly pale yellow at edge. Hemelytron: Bases of outer margins narrowly pale yellow; one cluster of dense black punctures inside and near apex of median fracture; apical angle not sharp; membranes pale ochraceous with each apex about equal to or slightly passing beyond abdomen. Ostiolar peritreme very short.

Abdomen: Connexiva testaceous and broadly exposed, punctured blackly and evenly, its lateral margins linearly and narrowly pale yellow. Abdomen beneath more or less keeled at meson, basal spine with sharp apex and passing beyond anterior limits of mesocoxae. Stigmata narrowly black.

Male genitalia: Pygophore with ventral margin concave, lateral apexes distinctly angular. Paramere Lshaped, its apex broad and oblong, one cornute process at base. Aedeagus without sclerotized dorsal processes; apical conjunctival lobe developed and not bifurcate at apex; basolateral conjunctival lobes also developed and membranous. Vesica robust, shorter than apical limits of median penial plates.

Female genitalia: 1st gonocoxites slightly plump, with inner margins straight and contacted with each other entirely, apical margins laminate and slightly depressed. Apices of 9th paratergites shorter than those of 8th paratergites.

Distribution: China (Guangxi).

Etymology: Named for the distinctly concave basal half of the pronotal posterolateral margins.

Lelia decempunctata ( Motschulsky, 1860) ( Figs. 3–4 , 12–18)

Tropicoris decempunctata Motschulsky, 1860: 501 ; Kerzhner & Jansson, 1985: 43. Lelia porrigens Walker, 1867: 407 (syn. Distant, 1900: 425).

Renardia decempunctata, Jakovlev, 1876: 17 –18.

Diagnosis: With six black spots on the base of the scutellum. Basal half of the posterolateral margins of the pronotum straight. The specimens from Sichuan Province have the pronotal lateral angles more protuberant than those from Heilongjiang Province.

Male genitalia: Ventral margin of pygophore concave and lateral apexes of pygophore angular. Paramere L-shaped with a basal process, apical margin of this concave. Aedeagus with developed and bifurcate apical conjunctival lobe, and a pair of membranous basolateral conjunctival lobes.
