Diagnostic characters: Measurements, see Table IV. Male: Characterized by the following combination of characters: head and pronotum reddish brown, antennae brown, sometimes paler; hemelytra brown; underside of body dark brown, with sternal area sometimes paler; legs and labium, brown to pale brown. Antennal segment II equal to or shorter than length of head, thickened at apex; antennal segments (I:II:III:IV) 1: 2.7: 2.1: 2.1; head prolonged anteriorly from base of antennae; hemelytra smooth, dorsal pilosity medium-sized, sparse; forefemora thick, pads large; short and thick copulatory spines on left margin of sternite VI, ( Fig. 170 ); pygophore ( Fig. 171 ) with aedeagus showing a processus penniformis ( Fig. 172 ); left paramere straight and basally enlarged, apically subquadrate ( Fig. 173 ). Female: Similar to male in measurements and coloration. Antennal segments (I:II:III:IV) 1: 2.6: 2.4: 2.4. Brachypterous form present.

Distribution: Honduras, Nicaragua, Grenada, Grenadines, Guadeloupe, Jamaica, Saint Vincent, Trinidad & Tobago, Colombia. ( Fig. 144 ).

Material examined: COLOMBIA: ♀ on orchid, Hoboken , N. J., 3-V-1941. USNM ; ♂ Idem , D.C. Insp., house, 22-I-1940 (slide-mounted). MACN ; GRENADA: 2♀ W. I., Chantilly Est. , (Windward Side), H. H. Smith, L. V. USNM ; 9♀, 1♂ W. I., Balthazar, (Windward Side), H. H. Smith. USNM & BMNH ; ♀ W. I., Grand Étang , Windward Side, 1000 ft., H. H. Smith, L. V. USNM ; ♀ (brachypter) W. I., Soubise , (Windward Side), H. H. Smith, 112; 95–206. BMNH ; ♀ H. H. Smith, 99–37. BMNH ; GRENADINE: ♀ W. I., Mustique I., H. H. Smith. BMNH ; HONDURAS: ♀ Ananas, Galveston , TX., 6-VII-1936. USNM ; JAMAICA: ♂ N. Y. City , 27-V-1937. USNM ; NICARAGUA: ♂ León, X-1989, Garcete. MACN ; 2♀ Zelaya, Sulum , 14º15’N – 84º36’W, I-1996, J. M. Maës-Hernandez. MLEN ; SAINT VINCENT: ♀ W. I., (Leeward Side), H. H. Smith, 95–206. BMNH ; TRINIDAD: ♀ Intercept. Mobile , 2-II-1961, Alabama, dead on boat. USNM .

Discussion: Easily distinguishable by the short second antennal segment, by the left paramere’s being straight and enlarged at base, and by occurrence of brachypterous females.
