4. Laricobius daliensis Háva, 2009b

(figs 4, 35)

Diagnosis. Body unicolored. Head dark; ocelli present. Prothorax quadrate without well developed lateral carina, sides not strongly explanate. Pronotum dark; posterior tooth absent. Scutellum dark. Surface of elytra incurvate; elytral punctures posteriorly confluent. Epipleura dark. Ventrites dark. Femora dark. Tibiae dark. Aedeagus with median carina on phallobase; medium lobe subacute; apices of parameres without an internal ridge.

Description. Length 2.54. Body unicolored black; antenna with AI black, funicle light tan, club brown; palpi tan, extreme bases of tibiae and tarsi brown. Head with ocelli; u-shaped furrow indistinct; interocular distance about 2.5x the width of the eye; macropunctures ovate and shallowly impressed but slghtly more impressed on frons; micropunctures coarse; setation very short and suberect, length shorter than 1/3 the width of the eye. Antenna with length of A3 about equal to A4, ratios 1.9:1.5:1.2:1.3:1.4:1.3:1.3:1.0:1.6:1.6:2.2; A11 strongly asymmetrical. Prothorax quadrate and highly convex, widest at middle, sides sinuate; about 0.81 x as long as wide (pronotal length/greatest pronotal width = 0.81); depth = 0.36; pronotum not laterally explanate, lateral carina without a distinct sharp edge; anterior angle acute, deflected, and forming a short laterally directed tooth (the angle formed between the anterior margin and lateral carina, excluding the tooth is about 60°); posterior angle indistinct and broadly rounded and without a short tooth; anterior foveae visible only in lateral view, posterior fovea visible dorsally; macropunctures ovate, deep, anteriorly contiguous or well-separated; micropunctures coarse; setae short, erect, and about 1/3 the width of eye. Elytra about 3.16 x as long as wide (elytral length/greatest elytral width = 3.16) and 3.38 x as long as pronotum (elytral length/pronotal length = 3.38); surface incurvate at basal third; macropunctures, especially of striae 1–4, coalescing posteriorly to form grooves, separated by an average of ½ to 1 puncture diameter, but those of striae 1–3 fusing at incurvature; micropunctures sparse; microsculpture not visible; setae suberect and short, about 1/3 length of the eye. Aedeagus with phallobase subquadrate, about 2/3 the length of the median lobe, median carina present; median lobe projecting slightly beyond apices of parameres, apex subacute, median groove present; parameres broad and acute with a distinct subapical tooth, moderately short setae present on apices. Spiculum gastrale apically broad.

Comments. Among the species that have the elytral punctures posteriorly coalescing, L. daliensis is the only species with dark tibiae that is the same color as the femora. This species is known from a single specimen. The aedeagus of the type specimen was drawn and observed from its original placement on the card with the specimen, therefore some of the aedeagal characters were not observed (the width of the median lobe, the placement of ostium and presence of internal subapical ridge).

Distribution. China: Yunnan.
