Smith SM, Beaver RA, and Cognato AI. 2020b. A monograph of the Xyleborini (Coleoptera, Curculionidae, Scolytinae) of the Indochinese Peninsula (except Malaysia) and China. ZooKeys 983: 1-442. https://doi.org/10.3897/zookeys.983.52630): 162.
Diagnosis
3.1−3.2 mm long (mean = 3.14 mm; n = 5); 2.38−2.46 times as long as wide. This species can be distinguished by the lack of a tuft of setaeseta:
small hair-like or scale-like structure
along the elytralelytral:
pertaining to the elytra
basebase:
point or edge closest to the body; opposite of apex
; declivitydeclivity:
downward slope of either the pronotum or elytra
rounded; elytraelytron:
the two sclerotized forewings of beetles that protect and cover the flight wings
shining; striaestria:
punctures in rows, which may or may not be impressed to make grooves
and interstriaeinterstria:
longitudinal spaces along the elytra between the striae, which is not as<br />
impressed and bear smaller punctures.
distinct; interstrial punctures confusedconfused:
of markings, having indefinite outlines or running together as lines or spots without definite pattern; usually referring to punctures
; body lightly setose; antennalantennal:
pertaining to the antennae
club as broad as tall; protibiaprotibia:
tibia of the first pair of legs
distinctly triangular; pronotumpronotum:
the dorsal surface of the thorax
basic (type 0) when viewed laterally, basic (type 2) when viewed dorsally; and anterioranterior:
the front or forward; opposite of posterior
margin of the pronotumpronotum:
the dorsal surface of the thorax
without a row of serrationsserration:
row of asperities; a saw-like structure
.
This species strongly resembles Xylosandrus formosae which also lacks a distinct mycangial tuftmycangial tuft:
tuft of setae that denotes the mycangia exterior opening
(at the basebase:
point or edge closest to the body; opposite of apex
of the pronotumpronotum:
the dorsal surface of the thorax
) and both have triangular protibiaprotibia:
tibia of the first pair of legs
. Coptodryas n. sp. 2 can be distinguished by the antennalantennal:
pertaining to the antennae
club type 3 (as described for genus), and elytralelytral:
pertaining to the elytra
basebase:
point or edge closest to the body; opposite of apex
sinuate and costate.
May be confused with
Euwallacea fornicatus, E. kuroshio, E. perbrevis, Microperus fulvulus, and Xylosandrus formosae
