Abstract This paper deals with two species of the Cerambycid genus Cyanagapanthia Breuning from China , in-
cluding a new species:C.aurecens sp.nov.A key to the genus is provided.The type specimen is deposited in the In-
sect Collection , Nakai University , China.
Key words Coleoptera , Cerambycidae , Cyanagapanthia , new species
Breuning (1968)established the genus Cy-
anagapanthia Breuning based on the type species
Cyanagapanthia bicolor.In general , Cerambycolo-
gists included the genus in Agnini of the subfamily
Lamiinae and ranked near Cribragapanthia Pic and
Anameromorpha Pic.The genus was small and
rarely collected , with only one known species from
south Asia.
Generic diagnosis (based on both the type
species and the new species):Body metallic blue ,
elongate.Antennae not fringed beneath , longer
than body;antennal tubercles fairly raised;scape
stout and short , cicatrix complete;third antennal
segment distinctly longer than fourth , twice as long
as scape;eyes coarsely facetted , deep emarginate ,
lower lobes longer than broad.Pronotum broader
than long , lateral spine well-developed.Elytra
elongate , subparallel , narrowly rounded apically;
middle tibiae not sulcate externally , tarsal claws di-
vergent.
Key to species of Cynagappanthia from the world
1.Elytra metallic green , covered with short fine grayish green
pubescence;lower lobe of eyes deeper than broad;scutellum
triangular.Body length:16 -19 mm;breadth:5 -6 mm.

Cyanagapanthia aurecens sp.nov.(Figs.1 ～ 3)
Body elongate.Head , prothorax , ventral sur-
face , scape and legs metallic blue.Scutellum
densely covered grayish white pubescence;pronotal
disc clothed sparsely golden hairs.Elytra metallic
blue , densely provided with erect golden hairs ,
more dense toward the apex.Antennae brownish
black , sparsely decorated beneath with black hair;
sides of frons , inner margin of eyes and hind genae
densely clothed with white pubescence;ventral sur-
face covered with fine grayish white pubescence and
speckled with grayish yellow.
Vertex deeply concave; frons convex and
sparsely punctured , broader than deep;deeply gro-
oved medially on frons and occiput;eyes deeply
emarginate , coarsely facetted , lower lobe squarish
and longer than genae.Antennae longer than body;

gradually shorter and their proportion in length as
follows:4.0∶0.7∶8.5∶7.4∶6.6∶6.0∶4.4∶3.2∶3.
0∶2.6∶3.0.Prothorax broader than long , deeply
transversely depressed anteriorly and posteriorly ,
coarsely punctured , densely;lateral tubercles an-
gulate and dorsal-laterally pointed.Scutellum round
behind;elytra entirely rugulose , subparallel at
sides and slightly broader behindmiddle and round-
ed apically.Femora more or less clavate;anterior
coxal cavities closed behind and mesocoxal ones
open to epimera;middle tibiae not sulcate external-
ly;claws divergent.
Female reproductive organ(figs.2-3):Ovi-
positor separated at lower middle near apex , deco-
rated with merged baculum in sides;coxite lobe
hardly chitinized and bear small styli which slightly
chitinized;vagina fairly folded in vaginal plate
which developed and sclerotized;bursa copulatrix
clavate and curved , moderately expanded at apex;
spermatheca long with irregular basal portion and its
apical portion even clavate.
Length:16.0mm;breadth:5.0mm.

Distribution:China(Yunnan).
Remarks:This new species is similar to Cy-
anagapanthia bicolor Breuing 1968 , but can be eas-
ily distinguished from the latter by the following
characters:elytra metallic blue densely decorated
with golden pubescence instead of elytra metallic
green covered with few short fine grayish green pu-
bescence;lower lobe of eyes squarish instead of
deeper than broad;scutellum semicircle instead of
triangular and elytra rugulose entirely coarsely in-
stead of rugulose finely , etc.
