5. Aulacogenia papilla Zhao & Cai , sp. nov. ( Figs. 31–41 )

Description. Color. Dark brown, suffused with irregular paler and darker markings. Eyes black; with Y­shaped hairless depression on head above, longitudinal depression on pronotum, scutellum, longitudinal darker markings on hemelytron, stripes on lateral sides of mesothoracic sternum, most of metathoracic sternum, legs (except spots on femur, base of tibia, annulation subbasally on tibia or irregular paler markings on subbasal portion), posterior half of each segment of connexivum, 5 longitudinal stripes on abdomen beneath dark black; most of head beneath, paler markings on first rostral segment, carinae on pronotum grayish yellow; base of first antennal segment, apex of femur and markings on femur, base of tibia, annulation subbasally on tibia or irregular paler markings on subbasal portion, anterior half of each segment of connexivum pale yellow to dark yellow; longitudinal paler stripes and some irregular paler markings on hemelytron grayish white.

Structure. Medium sized. Anteocular portion distinctly longer than postocular portion, lower margin of anteocular portion feebly concave upwards ( Fig. 36 ); first antennal segment slightly shorter than anteocular portion, second antennal segment longer than first rostral segment; antennal tubercles corneous; inner antennal processes developed, apical part rounded, distinctly reflexed upwards; lower margin of postocular portion with 2 nodular tubercles, anterior tubercle bigger than posterior one. Anterior pronotal lobe distinctly shorter than posterior pronotal lobe, posterior portion of longitudinal depression on anterior pronotal lobe deeper; posterior pronotal lobe sublaterally with 4 longitudinal carinae, depressed portion on posterior pronotal lobe distinctly wrinkled; lateral angles of posterior pronotal lobe papilla­shaped ( Figs. 31 , 36 ). Middle of scutellum longitudinally depressed. Fore tibia not wider than fore femur. Posterior angle of each segment of abdomen distinctly protruding ( Figs. 31 , 37, 38 ).

Measurements. ɗ. Body length 12.53, maximum width of abdomen 3.73, head length 2.20, length of anteocular part 1.07, length of postocular part 0.67, length of synthlipsis 0.60, distance between ocelli 0.33, length of antennal segments I:II:III:IV=0.93:1.33:?:?, length of rostral segments I:II:III=1.05:0.37:0.53, length of anterior lobe of pronotum 1.00, length of posterior lobe of pronotum 1.33, maximum width of pronotum 2.62, length of scutellum 0.73, length of hemelytron 7.53.

Type material. Holotype, ɗ, China, Yunnan, Xishuangbanna, Mengla, Yaoqu, 620 m, 1991­V­6, Wanzhi Cai leg., by light trap, kept in CAU.

Etymology. The specific name refers to the papilla­shaped processes on the lateral angles of the posterior pronotal lobe.

Distribution. China (Yunnan).

Remarks. The new species is similar to A. vicina Miller , but in the former the antennal tubercle is longer, the inner antennal process is distinctly reflexed upwards, and the nodular tubercles on lower margin of postocular portion are larger and distinct. This species belongs to the acutangula group.
