Acanthaspis fulviconnexa sp. nov.

( Figs 65–78 , 211 )

Description. Colouration. Body dark brown to black, shining. Head brown to dark brown; eyes brown to grayish brown; spots at external margin of ocelli yellow to brown; collar processes, lateral pronotal angles, two quadrate spots on posterior pronotal lobe, markings on thoracic pleuron, diagonal fascia on corium, connexivum yellow; femora red brown to dark red brown; tibia (except base and apex) yellowish brown to brown; tarsi dull yellow to brown ( Figs 65 , 211 ).

Structure. Small sized. Venter of body sparely clothed with short and long yellowish shining setae; coxae, trochanters, basal pro- and mesofemora with dense yellowish shining setae ventrally; dorsum of head, pronotum (except yellow area on posterior lobe), scutellum, apical halves of femora, and tibiae sparsely covered by fuscous long setae; antennae with thick or thin dark brown short setae. Head oblong, the longitudinal depression between eyes thin in the middle and wide at base and apex; transverse constriction before ocellar area shallow; anteocular portion as long as postocular; mandibular plates not prominent, as flat as clypeus; maxillary plates swollen, apex rounded; gena rounded; ocelli not prominent; first visible segment of rostrum slightly longer than second; first antennal segment shorter than head ( Figs 65 , 66 ). Collar processes developed, tuberculiform; anterior pronotal lobe slightly shorter than posterior, distinctly sculptured; posterior lobe wrinkled, base with a shallow longitudinal depression along midline, humeral angles spinous, produced posteriad; posterior margin shallowly concave. Hemelytron of female reaching, of male distinctly surpassing abdominal apex. Connexivum rather strongly reflexed, posterior angle of second segment prominent. Fossula spongiosa occupying about half of length of protibia. Parameres irregular shaped, thin at base and broadening apically, tip with a dentate process ( Figs 71–74 ); median process of pygophore of medium size, apex blunt ( Figs 69, 70, 77 ); basal plate strong, apex swollen; basal plate bridge slender; pedicel thick; dorsal phallothecal sclerite strongly sclerotized in its distal half, its apex sharp; struts fused, but their basal portions separated, reaching to distal part of phallosoma ( Figs 75, 76 ); a row of endosoma process laterally flat. Female with eighth abdominal tergite broad horizontally, posterior margin nearly straight; ninth and tenth tergites fused, median length shorter than eighth tergite, lateral margin swollen, with long thick setae, center depressed; first valvifer big and broad, visible part of first valvula triangular, apex sharp; styloid invisible ( Figs 67, 68 ).

Measurements [in mm, ♀ (n=1) / ♂ (n=1)]. Body length 12.1/13.8; maximum width abdomen 4.1/3.8; Head length 2.1/2.3; length of anteocular part 0.8/0.8; length of postocular part 0.85/0.9; length of synthlipsis 0.7/0.7; interocellar space 0.15/0.2; length of antennal segments I–IV= 1.2/1.5, 2.4/2.6, 3.5/missing, 2.8/missing; length of visible rostral segments I–III= 1.0/1.0, 0.85/0.9, 0.45/0.45; length of anterior lobe of pronotum 1.0/1.1; length of posterior lobe of pronotum 1.5/1.6; maximum width of thorax 3.0/3.4; length of scutellum 1.2/1.3; length of hemelytron 4.1/3.8.

Type material. Holotype, ♀, “ China, Yunnan, Jinghong, 10.IV.1987, Han Mingsheng ” [rectangular white]; “ Holotype, Acanthaspis fulviconnexa Cao, Rédei, Li & Cai ” [rectangular red] ( CAU) . Paratype, 1♂, “ China, Yunnan, Xishuangbanna, Xiaomengyang, 9.IX. 1958, 850 m, Zhang Yi ”; “ Paratype, Acanthaspis fulviconnexa Cao, Rédei, Li & Cai ” ( CAU) .

Distribution in China. Yunnan (Jinghong, Xiaomengyang) ( Fig. 78 ).

Etymology. The specific name refers to yellow coloured connexivum of this reduviid.

Remarks. The colour pattern of this species is similar to A. cincticrus Stål , A. westermanni Reuter with respect to the longitudinal fascia on the corium. The combination of the relatively small size, the distinctive colour of the pronotum, the characteristic longitudinal fascia of the corium, and the uniformly light connexivum make it easy to differentiate this new species from above mentioned two species.
