Measurements. Total length: 16.0– 18.8 mm; abdominal width: 8.2–9.7 mm; head length: 1.6–2.1 mm; head width: 3.0– 3.3 mm; antennomeres length: I: 0.8–1.0; II: 1.5–1.7; III: 1.6–2.0; IV: 3.4–4.1; V: 3.9–4.4; pronotum length: 3.4–3.9 mm; pronotum width: 9.4–11.5 mm.

Diagnosis. Pygophore with posterolateral angles straight in dorsal view ( Fig. 23 ). Margin of the dorsal rim of pygophore sinuous ( Fig. 23 ). Superior process of genital cup shallow and small, not reaching apices of the paramere projections ( Fig. 24 ). Paramere with anterior projection short and rounded, sinuous and directed to the proctiger; lateral projection directed to the posterolateral angle ( Fig. 24 ). Female internal genitalia with capSUla SeminaliS distinctly globose and projections slightly surpassing posterior annular flange ( Fig. 40 ); sclerotized part of gonapophysis 9 larger than in P. nigrovittata ; DUctUS receptacUli after vesicular area shorter than in P. nigrovittata ( Figs. 40, 41 ).

Discussion. Distribution of the species extended to Mexico and Costa Rica. Male and female genitalia of P. celSa are described for the first time. This species is quite similar to P. DiStanti sp. n. However, P. celSa can be distinguished by the humeral angle straight, shape of the parameres and superior process of genital cup. Internal female genitalia probably are also typical but only two species were dissected. This is the only species of PlagaeDeSSa known to Central America so far.

Distribution ( Fig. 52 ). MEXICO: Veracruz; COSTA RICA: Alajuela, Guanacaste, Limón; PANAMA: Barro Colorado.
