Materials Examined
Type material. Holotype: CHINA: Zhejiang Prov.:3, West Tianmushan Mt. (30 ° 18 ’ 31 ”N119 ° 29 ’01”E), Haoling, elev. 800 m, Jia-Yao Hu & Liang Tang leg, 24.viii. 2007. Paratypes: CHINA: Zhejiang Prov.:2 ƤƤ, same data as holotype (all SHNUC).
Description
Description.Male. Body (Fig. 9) reddish-brown, maxillary palpi, elytra and tarsi lighter in color; body length 3.53 mm, combined width of elytra 1.27 mm. Head longer than wide, frontal margin anterior to eyes narrowed toward apex. Antenna (Fig. 98) with scape as long as segments II–IV combined, antennomeres from pedicel to IV subequal in length, V slightly longer than IV, VI 1.3 times as long as V, VII slightly shorter than VI, VIII the shortest, IX–XI clubbed, IX elongate, 1.5 times as long as X, slightly expanded from base toward apex, X shorter but wider, narrowed at base, XI nearly oval, 1.5 times as long as X, narrowed from middle toward apex. Maxillary palpus (Fig. 146) similar to that of P. cornutus. Mandibles (Fig. 135) similar to that of P. cornutus, right mandible somewhat reduced (probably only in the dissected specimen).
Pronotum longer than wide, coarsely punctured and densely pubescent. Elytra (Fig. 21) each covered with long hair at apex. Legs with protrochanter (Fig. 73), profemur and mesotrochanter (Fig. 74) each bearing a small spine. Abdomen (Figs. 42, 43) with tergite IV more than twice as long as V; tergite VIII (Fig. 119) narrowed from middle toward apex, apical margin flattened, but slightly more rounded at apex, sternite VIII (Fig. 118) transverse, narrowed toward apex from apical one-third, emarginate medially. Aedeagus (Figs. 166, 167) with median lobe expanded and pointed at apex in dorsal view. Endophallus (Fig. 184) with two sclerites: left halberd-shaped, right shaped as spine, barely attached to base of left sclerite and bent in apical one-third; parameres not observed. Female. Smaller than male in size, similar to male in form; basal metaventral processes absent.
Discussion
Remarks. The new species can be readily distinguished by 1) antennomere VIII the shortest, 2) aedeagus with median lobe distinctively narrowed and apex pointed.
Distribution
Distribution.China (Zhejiang Province).
Etymology
Etymology. The speces name is compound noun in apposition based on the Latin adjective " latus ", meaning "broad", and Latin noun " lobus ", meaning "a lobe". The name refers to the expanded median lobe of aedeagus.
