Calocerus klimschi BERNHAUER, 1908: 285
Type material examined: female, holotype: Brazil: Santa Catarina, leg. Klimsch( FMNH). Further material examined: Guyana: 1 female, Region8, Iwokrama Forest, 1 kmW Kurupukari, Iwokrama Field. Stn.( 58°41.4'W, 4°40.19'N), under bark, 60 melev. 2.6.2001, leg. R. Brooks& Z. Falin#GUY1BF01121 ( KNHM); Maroni, without further data ( BMNH); French Guiana: 2 females, Matoury, 41.9 kmSSW on Hwy.N2 ( 52°24.17'W, 4°34.51'N), under bark, 125 melevation, 28.5.1997, leg. J. Ashe& R. Brooks#FG1AB97068 ( KNHM); 3 males, 7 females, Saül, under bark, 3.–4.1999, leg. A. Berkov( AMNH, UIC); Bolivia: 1 male, Santa Cruz Dept., 3.7 kmSSW Buena Vista Hotel Floray Fauna( 63°33.15'W, 17°29.95'S), Chiquitano forestleaf litter, 400–440 melevation, 5.11.2002, leg. R. Leschen#BOL1L02-021 ( KNHM); 1 female, Cochabamba Prov., Cochabamba, 67.5 kmNE Est. Biol. Valle del Sajita, Univ. de San Simon( 64°47.52'W, 17°06.33'S), collected by flight intercept trap, 300 melevation, 7.– 9.2.1999, leg. R. Hanley#BOL1H99057 ( KNHM).
Diagnosis: G. klimschiis the smallest species among the similar species listed under the G. cognatum-group. It can be identified by the shiny head. The microsculpture of the head of G. cognatumand G. denieriis more distinct and surface, thus, less shiny. Moreover, the apical lobe of the aedeagus is thicker and has numerous sensillae, in particular, at apex, whereas the apical lobe of the aedeagus in G. cognatumand G. denierihas only few sensillae.
Description: Length: 1.85 mm. Colouration: Dark reddish brown; elytra lighter reddish; legs still lighter; yellowish. Head 0.25 mmlong, 0.35 mmwide; eyes slightly prominent; slightly shorter than temples; temples smoothly rounded to neck in convex curve; sides in front of eyes up to base of antennae parallel; parallel part approximately as long as length of eyes; in front of antennal base angu- late in nearly rectangular angle; sinuate to anterior edge of clypeus in concave curve; anterior width of clypeus slightly shorter than distance between base of antennae; setiferous punctation deep and moderately dense; punctures on disc larger than on clypeus; interstices between punctures varying, but at least as wide as diameter of punctures; with remnants of weak microsculpture; surface shiny. Figs 18–19: Aedeagus (A) and antenna (B) of Glyptoma klimschi( 18), G. schuhi( 19); scale bar: 0.1 mm. Antennae as long as head and pronotum combined; all antennomeres approximately equally wide; second antennomere approximately quadrate; third to tenth antennomere slightly wider than long; second to tenth antennomere with few long yellow setae; setae as long as or slightly longer than width of antennomeres. Pronotum: 0.35 mmlong 0.27 mmwide; widest at anterior third; narrowed to anterior angles in short convex curve; anterior angles obtuse; front edge smoothly prominent; in posterior two third, narrowed to posterior angles in concave curve; posterior angles obtuse; posterior edge as wide as neck; disc with large setiferous punctures; size of punctures varying; lateral punctures very dense; partly coriaceous; forming irregular elongate impressions; two larger punctures at middle in front of posterior edge; on disc of anterior half with transverse impunctate area; surface of punctures with netlike microsculpture; interstices between punctures with remnants of weak longitudinally striate microsculpture; surface shiny. Elytra: 0.45 mmlong, 0.37 mmwide; sides slightly convex, but nearly parallel; shoulders rounded to emarginate anterior edge; discal carina distinct; lateral carina absent; suture line marked by line of close small punctures; continued to posterior margin; on area between suture line and discal carina with two short lines of setiferous coriaceous punctures; one slightly diagonal line in anterior half and one longitudinal row close to discal carina in posterior half; both lines overlapping at middle; laterad to discal carina with line of setiferous coriaceous punctures partly forming elongate impressions; laterad further rows of coriaceous punctures; with remnants of weak longitudinally striate microsculpture; surface shiny. Abdomen on each abdominal segment with irregular transverse rows of large setiferous punctures; punctures much larger than on the pronotum; interstices on segments III to VII restricted to small ridges; posteriad to middle of segments III to VII with impunctate area; weak microsculpture netlike; surface shiny. Aedeagus obtusely angulate between basal and apical lobe; apical lobe slightly curved; ending in acute apex; apex shortly curved; pointing ventrad; dense group of sensillae at apex; numerous sensillae from base of apical lobe to close to apex; paramere slightly longer than basal third of apical lobe; with several sensillae.
