Diagnosis.
Chen (1964) described the subspecies Aplosonyx ancora fulvescens from three specimens collected in Hainan and Fujian. Examination of the type specimen and the additional seven specimens revealed that this subspecies differs from Aplosonyx ancora in antennae with antennomeres 1-3 yellow and antennomeres 4-11 brown, the pronotum and elytra sparsely covered with small punctures, the apex of the aedeagus slightly pointed, in lateral view apex is bent, the base is wide, and it gradually narrows to the apex. The pronotum and elytra of Aplosonyx ancora are densely covered with punctures, the antennomeres 1-6 yellow, the aedeagus apex is distinctly pointed. Because these differences are constant among the specimens examined, we elevate the subspecies Aplosonyx ancora fulvescens to species level. This species is also similar to Aplosonyx ancorella sp. nov., which differs in the antennae with antennomeres 1-7 yellow and antennomeres 8-11 brown, the abdomen with five pairs of black spots, and the pronotum and elytra densely covered with large punctures.
Redescription.
Male. Length 10.6-12.6 mm, width 5.8-6.8 mm.
Head, pronotum, abdomen and leg yellow, elytra reddish brown, antennae brown with antennomeres 1-3 yellow, scutellum black, ventral surface of thorax black with yellow middle, pronotum with 1 small black spot in base, elytra with a broad purplish band from anterior to middle, which extends forward along suture and expends again on base.
Vertex finely covered with punctures. Interocular space 2.2 × as wide as transverse diameter of eye. Interantennal space 1.4 × as wide as transverse diameter of antennal socket. Frontal tubercles transverse, distinctly raised, each separated by a deep furrow; antennae slender, 0.65 × as long as body; antennomeres 1-3 shiny; antennomeres 4-11 covered with pubescence, antennomere 2 shortest, antennomere 3 approximately 1.5 × as long as second; antennomere 4 longest, approximately 1.5 × as long as antennomeres 2 and 3 combined; antennomeres 5-10 gradually shortened, shorter than antennomere 4; antennomere 11 slightly longer than antennomere 10, pointed.
Pronotum approximately 2 × as wide as long, lateral border margined, widest at posterior corners, disc with transverse furrow, sparsely covered with several large punctures, the interstices of punctures equal to diameter of individual punctures.
Scutellum triangular, finely covered with punctures.
Elytra wider than pronotum, 0.78 × as long as body, 1.65 × as long as wide, epipleura wide at anterior 1/4, posteriorly gradually narrowing towards apex, dorsal surface slightly convex, irregularly covered with punctures, the interstices of punctures equal to diameter of individual punctures and lightly covered with small punctures in the interstices.
Metasternum 2 × as long as mesosternum. Ventral surface of abdomen with five ventrites, ventrite 1 longest, ventrites 2-4 gradually shortened, apical ventrite slightly longer than ventrite 3, two subtriangular incisions.
Aedeagus slender, basally widened, apex slightly pointed, in lateral view apex bent.
Female. Length 10.8-12.4 mm, width 6.0-6.8 mm.
Antennae slightly thinner than in male, antennomere 2 shortest, antennomere 3 longer than antennomere 2, approximately 1.8 × as long as second; antennomere 4 longest, 1.6 × as long as antennomeres 2 and 3 combined; apical sternite without incisions.
Distribution.
China: Fujian, Hainan.
