Cephennodes (Cephennodes) zwaluwenburgi Zimmerman

( Figs 2–3 )

Cephennodes zwaluwenburgi Zimmerman, 1942: 239 .

Type material examined. Holotype: Hawaii: ♂, three labels: “Honolulu T.H. / v – 4 – 37 At light” [white,

printed and handwritten], “C ECZimmerman Collector” [white, printed], “ Holotype No. 1372 / Cephennodes / zwaluwenburgi / Zimmerman” [white with left margin red, printed and handwritten] ( BPBM) .

Remarks. This species is the only Cephennodes known to occur in Hawaii, and can be easily identified by its unique aedeagus ( Figs 2–3 ). The asymetrical median lobe and free parameres place this species in Cephennodes (s. str.). Externally this is an unremarkable species, with small adults (body length of the holotype 1.04 mm) and relatively elongate elytra (elytral index 1.21). Punctures on the frons and vertex are tiny and shallow but sharply marked and dense; those on pronotum are dense but similarly small, deep and with sharply marked margins, separated by spaces subequal to their diameters; punctures on elytra are much sparser than those on pronotum but slightly larger, sharply marked. External features are similar to those of many Asian and Australian congeners (described and awaiting description); the shape of the oval, capsular portion of the aedeagus, the broad and dorsally recurved distal projections and short parameres allow for unambiguous identification.
