Paragnorimus atratus Smith , new species

Fig. 5-6 , 9

Type locality. Cerro de Mono (2275 m), Zacapa, Guatemala.

Type series. Holotype male and allotype female at UNSM labeled “ GUATEMALA, Zacapa / Cerro de Mono , 2275m / May 25-28, 1997 / E. Giesbert, coll.” (typeset). Two male paratypes at ABTS (1), CMNC (1) both with identical data labels to the holotype and allotype. All types listed above also bear my red or yellow type label.

Description of holotype. Male. Length 11.0 mm, width 6.0 mm. Color: dorsal and ventral surface black ( Fig. 5 ). Head. Surface setose with black matt, punctures obscured; apical half of clypeus shiny black with distinct punctures. Clypeus weakly emarginated, apical margin elevated, length approximately equal to width, constricted basally at antennal insertion. Head without cretaceous markings. Antennae with 10 antennomeres, club length approximately equal to length of antennomeres 2-7. Maxillae with long, thin brush protruding beyond clypeus in dorsal view. Mentum thickly setose, obscuring surface. Pronotum. Surface setose with black matt, punctures obscured, without any cretaceous markings or bands. Marginal bead complete. Elytra. Surface sparsely setose, matt. Cretaceous band (1 on each side) thin, transverse, located medially. Elytral striae weakly defined to obscured. Pygidium . Surface rugose, moderately setose; disc without cretaceous markings, evenly convex. Venter. Thorax with scattered traces of cretaceous markings. Sternum densely setose with long setae obscuring surface. Abdominal sternites 2-5 without cretaceous bands. Legs. Protibiae with 2 teeth near apex. Mesotibiae with outer edge bowed medially. Tibial spurs acute, unmodified. Tarsi with ventral tufts of setae. Parameres. Apex dorsolaterally flattened, without teeth or processes ( Fig. 9 ).

Variation. Males: length 10.5-12.5 mm, width 5.5-6.0 mm. Male paratypes match the holotype description except both have a weak hint of a transverse pronotal band and some cretaceous markings on the abdominal sternites.

Sexual dimorphism. Female allotype: length 12.0 mm, width 5.5 mm. The female allotype ( Fig. 6 ) differs in the following characters: Head. Entire surface shiny black with distinct punctures. Clypeus apical margin not elevated. Antennal club length shorter than antennomeres 2-7. Pronotum. Surface shiny black with distinct puctures, with cretaceous markings along basal bead. Elytra. Surface with a second small cretaceous band located post-humerally. Pygidium . Surface rugose, moderately setose; disc flat, with cretaceous markings in basal half. Venter. Thorax with larger patches of cretaceous markings. Sternum densely setose with long setae not obscuring surface. Abdominal sternites 2-5 with thin cretaceous bands. Legs. Protibiae with 2 teeth near apex. Mesotibiae with weak tooth medially. Tarsi without ventral tufts of setae.

Etymology. The name atratus is Latin meaning “clothed in black.” This is in reference to the black coloration of this species.

Distribution. GUATEMALA - Zacapa (4): Cerro de Mono.

Temporal data. May (4).
