( SEMC).   Etymology.The epithet of this new species is formed from the Greek “stonyx” (sharp process), which describes the sharply prominent lateral process of the gonocoxites of this species.   Diagnosis.This species differs from other congeners by the following combination of characters: pronotum and elytra different in color, without any maculation on dorsal disc; metathoracic discrimen present in apical 1/5; subcoxal lines on abdominal sternite III present; pro- and mesotarsal segments II and III of males strongly dilated; tegmen very long, subparallel-sided in ventral view; TL/TW = 2.87 ( n= 1); apical margin of tegmen widely rounded in ventral view; median lobe subparallel-sided; apical margin of median lobe widely rounded; apices of gonocoxites square, with apicolateral corners sharply prominent laterally.  Similar Species.This new species is similar to  C. smileyeyes, but can be distinguished by the following combination of characters: pronotum without any maculation; elytra subparallel-sided; shape of sclerites of internal sac different; and apicolateral corners of gonocoxites sharply prominent laterally.   Description.Length 2.16–2.79 (2.50) mm, width 1.67–2.20 (1.98) mm, depth 0.85–1.23 (1.07) mm ( n= 4). Male.Body ( Fig. 15B–D) widely oval; dorsal disc of head (except paler apical area) reddish yellow to dark reddish brown; antennal segments I–VIII, pronotum, hypomera, prosternum (except apical area of prosternal process dark reddish brown), and elytral hypomera reddish yellow; elytra dark reddish brown to black, usually darker laterally than middle; scutellum reddish yellow to dark reddish brown; antennal club dark brown except apex paler. Head:Disc densely punctate; interspaces reticulate. Labrum feebly notched at middle. Antenna ( Fig. 18G) with club long and large, ACL/ASI-VIII = 0.86 ( n= 1); antennal segment XI with 2 oval antennal sensillae; approximate ratio of each segment ( n= 1) 4.00: 3.36: 2.20: 1.73: 1.67: 1.11: 1.00: 1.09: 2.63: 2.93: 8.37. Pronotum:2.58–3.04 (2.76) times as wide as long ( n= 4); disc densely punctate; punctures on disc large, slightly smaller than eye facets; interspaces reticulate. Scutellum:Disc densely punctate; punctures on disc about as large as those on pronotum; interspaces reticulate. Elytra:0.91– 0.97 (0.95) times as long as wide ( n= 4), 2.85– 3.43 (3.04) times as long as pronotum ( n= 4), subparallel-sided from base to basal 1/3; each elytron with 9 regular rows of punctures about as large as eye facet; interstices with dense minute punctures. Venter:Prosternum strongly convex along midline, with tuft of setae at middle. Metaventrite strongly convex; metathoracic discrimen present in apical 1/5. Abdominal sternite III with subcoxal lines; lateral margins of abdominal sternite VII strongly serrate. Legs:Robust; pro- and mesotarsal segments I–III strongly dilated; tarsal claws simple. Genitalia:Tegmen ( Fig. 18A, C, E) subparallel-sided; TL/TW = 2.87 ( n= 1); apical margin of tegmen widely rounded in ventral view; median lobe ( Fig. 18B, D, F) subparallel-sided in ventral view; apical margin of median lobe widely rounded in ventral view; sclerites of internal sac as in ( Fig. 18B, D, F). Female.Prosternum without tuft of setae at middle. Pro- and mesotarsal segments I–III more weakly dilated than those of males. Ovipositor ( Fig. 18H) with squared apices of gonocoxites; apicolateral corners of gonocoxites sharply prominent laterally.  Variability.This species expresses slight variations in body coloration, shape of the elytral margins, and appendages of the median lobe.   Distribution. Costa Rica, Panama, and Ecuador(Map 5).    Cyclocaccus morulusHisamatsu, new species( Figs. 15E, 16A–J, L–Q, 19, Map 5)   Type Series.  Holotype( SEMC): ♂, ‘ECUADOR: Napo, Yasuni/ Res.

( SEMC)   Etymology.The specific epithet means “dark colored,” a reference to the dark reddish brown body of this species.   Diagnosis.This species differs from other congeners by the following combination of characters: body completely dark reddish brown; metathoracic discrimen absent; subcoxal lines on abdomi- nal sternite III present; pro- and mesotarsal segments II and III of males strongly dilated; tegmen elongate, subparallel-sided; TL/TW = 2.94 ( n= 1); apical margin of tegmen widely rounded in ventral view; median lobe subparallel-sided; apical margin of median lobe widely rounded, with shallow emargination at middle; apices of gonocoxites square, with apicolateral corners widely rounded.  Similar Species.This new species is similar to  C. lescheniin the shape of antennal segment XI and male genitalia, but can be distinguished by the following combination of characters: body completely dark reddish brown; shape of sclerites of internal sac different.   Description.Length 2.12–2.59 (2.34) mm, width 1.74–2.13 (1.89) mm, depth 1.00–1.30 (1.10) mm ( n= 4). Male.Body ( Fig. 15E) oval; dorsal disc dark reddish brown; apical half of head, mouthparts, antennal segments I–VIII, elytral epipleura, and tarsi paler; antennal club dark brown except apex paler. Head:Disc densely punctate; interspaces reticulate. Labrum feebly notched at middle. Antenna ( Fig. 19C) with club long and large, ACL/ ASI-VIII = 0.66 ( n= 1); antennal segment XI with 2 oval antennal sensillae; approximate ratio of each segment ( n= 1) 3.86: 2.16: 2.41: 1.78: 1.65: 1.05: 1.14: 1.00: 2.46: 2.68: 4.84. Pronotum:2.77–2.99 (2.93) times as wide as long ( n= 4); disc densely punctate; punctures on disc large, slightly smaller than eye facets; interspaces reticulate. Scutellum:Disc densely punctate; punctures on disc about as large as those on pronotum; interspaces reticulate. Elytra:0.92–0.97 (0.94) times as long as wide ( n= 4), 3.11–3.29 (3.19) times as long as pronotum ( n= 4), subparallel-sided from base to basal 1/2; each elytron with 9 regular rows of punctures about as large as eye facet; interstices with dense, minute punctures. Venter:Prosternum strongly convex along midline, with tuft of setae at middle. Metaventrite strongly convex; metathoracic discrimen absent. Abdominal sternite III with subcoxal lines; abdominal sternite VII with dense punctures and short setae at apical area; lateral margins of abdominal sternite VII serrate. Legs:Robust; pro- and mesotarsal segments I to III strongly dilated; tarsal claws simple. Genitalia:Tegmen ( Fig. 19A) subparallel-sided; TL/TW = 2.94 ( n= 1); apical margin of tegmen widely rounded in ventral view; median lobe ( Fig. 19B) elongate, subparallel-sided in ventral view; apical margin of median lobe widely rounded, shallow emarginate at middle in ventral view; sclerites of internal sac as in Fig. 19B.  Female.Unknown.  Variability.No variation was apparent among specimens available for study.   Distribution. Ecuador, Brazil, and Paraguay(Map 5). 1995-05 INBIO Estacion Pitilla & S. de Santa & Cecilia & Prov.
