A d d i t i o n a l m a t e r i a l e x a m i n e d Turkmenistan: 1, 1, "Krasnowodsk" ( HNHM) ; 1 ex., Ashkhabad ( HNHM) .

C o m m e n t: The original description is based on "ein Exemplar aus Turcmenien" ( REITTER 1887).

R e d e s c r i p t i o n: Body length 2.3-2.5 mm. Body pale reddish; elytra yellowish.

Head with sharply angled posterior angles; microsculpture shallow; punctation fine and moderately dense. Eyes large, approximately three times as long as postocular region in dorsal view. Antennae ( Fig. 15 ) long; all antennomeres distinctly longer than wide; IV-V more than 3 times as long as wide; IX approximately three times as long as wide; X conspicuously oblong, approximately as long as the combined length of the three preceding antennomeres.

Pronotum strongly transverse, 1.75-1.80 times as wide as long; maximal width in posterior half; posterior angles rounded, obsolete; microsculpture very shallow; puncturation extremely fine.

Elytra somewhat wider than pronotum and dilated posteriad, at suture approximately as long as pronotum; punctation extremely fine; microsculpture somewhat more distinct than that of pronotum. Hind wings fully developed. Metatarsomere I very long, longer than the combined length of II-IV.

Abdomen with extremely fine punctation; microsculpture distinct; posterior margin of tergite VII with palisade fringe.

: median lobe of aedeagus of distinctive morphology ( Figs 17-18 ); paramere conspicuously large, 1.1 mm long.

C o m p a r a t i v e n o t e s: The species is readily distinguished from its congeners especially by the pale coloration, the conspicuously long antennae, and by the distinctive shape of the aedeagus.

D i s t r i b u t i o n a n d n a t u r a l h i s t o r y: Cypha rubicunda was previously known only from the vaguely specified type locality. It is here reported from two localities in Turkmenistan, one at the coast of the Caspian Sea and one near the northern slopes of the Kopetdagh mountains.
