Cataulaxpudens ( Distant, 1889)   ( Figs. 2C View Figure 2 , 3C View Figure 3 , 4C View Figure 4 , 5C View Figure 5 , 6D-F View Figure 6 , 7B View Figure 7 , 8B View Figure 8 )

Architaspudens Distant, 1889: 323   ; Lethierry & Severin, 1893: 85; Kirkaldy, 1909: 216. NEW COMBINATION

Distinctly shorter, and less densely punctured than in C. eximius   , but sometimes punctuation is arranged in longitudinal lines or in patches as in that species. Apex of scutellum subtriangular. Corium hardly longer than scutellum. Rostrum clearly surpassing the middle of the fourth abdominal sternite. Posterior margin of metasternumalmost as wide as anterior margin; median mesosternal plate conspicuously convex anteriorly.

Male. Apicalmargin ofhemelytral membrane slightly truncate and feebly sinuate, veins subparalell, ending well beforeapical margin ( Fig. 2C View Figure 2 ).

Measurements (mm). Length of head1.84(1.80-1.96); anteocularlength 1.22(1.14-1.31); width of head 3.68(3.60- 3.77); interocular width 2.12(1.96-2.29); interocelar width 1.06(0.98-1.14); length of antennal segments: I 0.65, II 1.26(1.14-1.31), III 1.26(1.14-1.31), IV 1.88(1.80-1.96), V 1. 96; pronotallength 3.03(2.95-3.11); pronotal width 7.54(7.38-7.70); length of scutellum 6.59(6.39-6.88); width of scutellum 5.08; abdominal width 7.21(7.05-7.38); total length 11.43(11.15-12.13).

Pygophore sub-rectangular; lobe of internal border of postero-lateral angles in a percurrent flange. Parameres simple, depressed, elongate-oval in outline ( Figs. 3C View Figure 3 , 4C View Figure 4 , 5C View Figure 5 ). Proctiger with 1+1 carina at mid length, converging posteriorly. Phallus   : articulatory apparatus stout, wider than phallotheca; processus capitati slender. Vesica with 1+1 dorsal process at base, processus vesicae shallow, collar like; ductus seminis distalis totally included in vesica ( Figs. 6D-F View Figure 6 ).

Female. Measurements (mm). Lengthofhead 2.18(1.96-2.29); anteocularlength 1.26(1.14- 1.31); width of head 3,83(3.60-4.10); interocular width 2.36(2.29-2.46); interocelar width 1.23(1.14-1.39); length of antennal segments: I 0.65, II 1. 44(1.31-1.47), III 1.27(1.14-1.31), IV 2.07(1.88-2.29), V 2.00(1.88-2.13); pronotallength 3.37(3.11- 3.60); pronotalwidth 7.79(7.38-8.20); length of scutellum 6.75(6.39-7.05); width of scutellum 5.05(4.92-5.24); abdominal width 7.38(6.72-8.03); total length 12.59(11.80- 13.61).

Gonocoxites 8 wider than long, sutural borders rectilinear, adjoining each other; distal border angulate. Laterotergites 9 simple, just surpassing transverse band connecting laterotergites 8 dorsally. Posterior borders of laterotergites 8 smoothlyrounded ( Fig. 7B View Figure 7 ). Anterior border of gonocoxites 9 concave, posterior border almost rectilinear; gonapophyses 9 with 1+1 thickenings near anterior limits. Orificium receptaculi surrounded by a conical, simple thickening of vaginal intima, chitinellipsen at each side of its base. Capsula   seminalis simple, globose ( Fig. 8B View Figure 8 ).

Type. Holotype female deposited at BMNH examined. Type locality: Volcan de Chiriqui, 2-3000ft, Panamá.

Material Examined. Panama: Canal Zone: male, female, Barro Colorado Island , V/24/ 1957, F. Schrader ( AMNH);   male, female, idem, IV/24/1962, H. Ruckes ( AMNH);   female, idem, VII/18/1956, C. W. & M. E. Rettenmeyer ( SEM);   female, idem, V/10-17/ 1964, WD & SS Duckworth ( USNM);   San Jose: male, Pearl Island , V/25/1944, Morrison JPE, collected at light ( USNM);   Porto Belo: female, IV/17/1912 ( AMNH);   Gatum Lake: male, Tres Rios Plantation , IX/04/1931, TOZschokke, E. P. Van Duzee Collection ( AMNH);   Venezuela: Zulia: female, Caimera, Sierra de Perija , IV/11/1960 ( MHNS).  

Comments. Similar to C. radians   by having simple parameres and membrane with subparalell veins ending well before apical margin. In C. pudens   the apicalmargin of hemelytral membrane isslightly truncate and feebly sinuate but in C. radians   it is straight.
