Wills text The Coleopterists Bulletin 2004 2004-03-31 58 1 97 101 http://dx.doi.org/10.1649/607 journal article 10.1649/607 1938-4394 10104300 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 ( Fig. 3 ) with scape oval, pedicel oval, shorter than scape, 0.7 3 flagellomere 1; flagellomere 2 ¼ 1.1 3 flagellomere 3, 1.0 3 flagellomere 7. Mouthparts piceous; maxillary palp with apical segment tapered and weakly flattened. Prothorax distinctly wider than long, L/W ¼ 2.2; pronotum covered with long prostrate yellow setae; disc densely, coarsely punctate, with punctures separated by a distance less than their own diameters. Prosternum with width of intercoxal process 0.9 3 width of procoxa. Elytra across humeri 1.3 3 width of pronotum. Median lobe of aedeagus in lateral view strongly and evenly curved ( Fig. 7 ); apex bluntly pointed ( Fig. 8 ); basal hood of moderate length, no distinct apodemes visible at lateral margins. Apical sclerite tapered, curved at tip ( Fig. 9 ). Figs. 10–12. Cryocolaspis crinita , female genitalia. 10) Ovipositor, ventral; 11) ovipositor, dorsal; 12) spermatheca. Female. Length: 3.5–3.8 mm . Head with labrum, frons, clypeus, eyes and antennae similar to male; mouthparts with apical segment of maxillary palp spindle-shaped. Prothorax distinctly wider than long, L/W ¼ 2.4; prosternum with width of intercoxal process 1.0 3 width of procoxa. Basal segments of fore- and middle tarsi not swollen ( Fig. 6 ). Elytra across humeri 1.3 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 ( Fig. 12 ) sclerotized, long, loosely coiled. Etymology. Crinita , from Latin, meaning hairy. Types. Holotype ? (INBio): COSTA RICA : San José Cerro de la Muerte, 19 km south and 3 km west of Empalme, 2,600 m , 9 8 39 9 N , 83 8 52 9 W , IV– VII-1992 . Allotype / (INBio): same locality, date and collector as holotype . Paratypes : 1 ? , 1 / (UCR), same locality and collector as holotype , XII-1992 ; 1 ? (NMNH), 1 / (INBio); COSTA RICA , Alajuela , P.N. Volcán Poas, P. Hanson, C. Godoy, R.W. Flowers 14-V- 2000 ; 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.
