E t y m o l o g y: The specific epithet (Latin, adjective: different, unequal) alludes to the conspicuously different lengths of the parameres of the aedeagus.
D e s c r i p t i o n: Body length 5.4 mm; length of forebody 5.1 mm. Coloration: body black, except for the rather narrowly brownish anterior three-fourths of the lateral margins; legs blackish, with the inner faces of the tibiae and the tarsi brownish; antennae blackish, with antennomeres II and III dark-brown with reddish-brown apices; maxillary palpi pale-brown.
Head ( Fig. 4 View Figs 1-8 ) deeply impressed near eyes, these impressions with coarse and somewhat irregular punctation; median and posterior portions of dorsal surface with three partly interrupted transverse series of coarse punctures situated in narrow impressions; between these impressions with smooth and glossy elevations; frons smooth and glossy. Antenna 2.4 mm long and shaped as in Fig. 6 View Figs 1-8 .
Pronotum ( Fig. 4 View Figs 1-8 ) 1.6 times as broad as long and 1.5 times as broad as head; lateral margins irregularly and distinctly dentate; middle of lateral portions with very deep impression, in front of and behind this impression with smooth area; in anterior twothirds of median portion with two pronounced oblong and smooth tubercles on either side of middle; postero-laterally with another smooth elevation on either side; between smooth elevations with very coarse punctation.
Elytra ( Fig. 5 View Figs 1-8 ) 2.6 times as long as pronotum and 1.38 times as long as combined width; lateral margins smoothly and weakly curved in dorsal view; punctation coarse and arranged in partly irregular series (except in posterior portion of elytra), these series interrupted by numerous (nearly 30 on each elytron) pronounced, large and strongly elevated smooth tubercles. Legs rather long and stout; femora, particularly metafemur, dilated; metatibia ( Fig. 12 View Figs 9-18 ) 1.5 mm long; all tibiae bisinuate.
3: protarsomeres I-IV moderately dilated; aedeagus ( Figs 13-14 View Figs 9-18 , 21-22 View Figs 19-25 ) 1.3 mm long; left paramere long, basally stout, and apically acute, distinctly extending beyond apex of median lobe; right paramere short and stout, far from reaching apex of median lobe; internal sac with two series composed of numerous small moderately sclerotized structures.
C o m p a r a t i v e n o t e s: This species is characterized particularly by the distinctive aedeagus with parameres of conspicuously different lengths and shapes, as well as by rather larger size, dark coloration, the presence of numerous pronounced elevations on the pronotum and elytra, and the modifications of the legs. It additionally differs from D. tricuspidatum , with which it shares the dark coloration and pronounced tubercles on the elytra, by larger size ( D. tricuspidatum : 4.3-4.6 mm), the absence of pale spots on the elytra, the absence of striate microsculpture on the head, differently arranged tubercles and impressions on the pronotum and elytra, dilated male protarsomeres I-IV, and probably also the modified legs with dilated femora and bisinuate tibae (not indicated in description of D. tricuspidatum ). For illustrations of the aedeagus of D. tricuspidatum see SMETANA (1996).
D i s t r i b u t i o n a n d b i o n o m i c s: The type locality is only some meters away from that of D. uncinatum (on the other side of the road) ( Map 1 View Map 1 ). The holotype was sifted from leaf litter and roots of herbs at the margin of a secondary deciduous forest at an altitude of 2030 m. The locality is illustrated in Fig. 27 View Fig .
