Cryocolaspis crinita
new species
Figs. 1–12
Male.
Length:
3.5–3.8 mm
. Head, pronotum and elytra shining chestnut brown to piceous, sometimes with faint iridescent sheen, with long erect yellow setae. Underside reddish piceous; legs and tarsi dark yellowish brown. Head with apex of labrum truncate, with two submedian setae and several lateral setae along outer apical angle. Punctures on clypeus separated by distance equal to the diameter of a puncture, and those on frons by distance less than the diameter of a puncture; surface between punctures microreticulate; antennal calli microreticulate and flat. Antenna (

Female.
Length:

3
width of pronotum. Sternum VIII (
Fig. 10
) weakly sclerotized laterally, basal apodeme expanded and weakening apically; a pair of rows of apicolateral setae present. Segment IX hemisternites with short basal rods, weakly sclerotized apically; baculum distinct, apical, longer than gonocoxae. Spermathecal duct (

) sclerotized, long, loosely coiled.
Etymology.
Crinita
, from Latin, meaning hairy.

; The specimens from Empalme were taken in a Malaise trap that was placed under a young oak tree in a pasture,;10 meters from the edge of cloud forest. A
paratype
from Volcán Poas, along with numerous specimens of an unidentified
Brachypnoea
, were beaten from flowers of
Cleyera thioides
(Theaceae)
, a tree growing in a pasture at the edge of the national park. That
paratype
bears the voucher label 11-RWF-00.
Discussion.
The male endophallus was not everted successfully, but appeared not to have any sclerotized structures. Under the proposed classification of the
Eumolpinae
given by Flowers (1999),
Cryocolaspis
fits in Division I, in the tribe
Adoxini
. The male genitalia lack the apomorphic characters of Division II (constricted base of the basal hood, subbasal fenestra and basal spurs on the median lobe), and the adults lack the modified middle and hind tibiae characteristic of the Division I Typophorini.
