DESCRIPTION: Forebody as in Fig. 47. Measurements (n=6): HW = 0.60 (0.51- 0.65); TW = 0.57 (0.49-0.62); PW = 0.53 (0.48-0.56); SW = 0.58 (0.54-0.61); MW = 0.73 (0.65-0.76); AW = 0.64 (0.59-0.70); HL = 0.49 (0.41-0.52); EL = 0.12 (0.10-0.14); FL = 0.10 (0.09-0.12); TL = 0.18 (0.15-0.21); PL = 0.44 (0.41-0.46); SL = 0.70 (0.68- 0.73); SC = 0.69 (0.67-0.71); FB = 1.69 (1.59-1.75); BL = 3.08 (2.65-3.45) mm. Body 'unicoloured', but appendages contrastingly light coloured. Head and pronotum blackish dark brown to pitch black (tips of supraantennal prominences lighter). Elytra dark brown (posteriorly darkening, blackish). Abdomen dark brown to pitch black. Legs, mouthparts and antennae yellow to light brown, antennae distinctly darkening from middle to apex, but leaving apex of last antennomere yellow. Pubescence short and sparse, but abdomen with much longer setae. Body surface unusually shiny.

Head and pronotum. Mid-antennal articles moderately elongate (antennomere 6 length:width = 0.070: 0.050 mm). Clypeus (Fig. 74) trapezoid, ratio of longitudinal distance of supraantennal prominence tip from eyefront to the same from clypeal front = 0.60-0.69. Infraocular ridge (Fig. 77) rather fine, combined with some punctures at inner eye border, slightly continuing after posterior edge of eye in a short process/keel. Temple rather broadly rounded, most curved in middle (but not angled). Pronotum (Fig. 75) with maximum width 1.45-1.70x base width, sides almost evenly rounded anteriorly, straight in posterior half, anterior angles slightly obtuse. Clypeal area and supraantennal prominences unpunctured (or clypeus with only a few tiny punctures). Clypeus not delimited by groove, only by contrastingly punctured areas. Shiny, unpunctate part of pronotal midline much longer than usual: occupies posterior 3/4 (or more) of length of pronotum, starting from a flat area not far from anterior edge of pronotum. Pronotal sides with a slight depression after middle. Head with about 16 'longitudinal' puncture lines, pronotum with about 16 'longitudinal' puncture lines, head punctation not loosened, pronotum with similar sized punctures to those on head, some interspaces between punctures on both.

Elytra and abdomen. Elytra (Fig. 76) slightly dilating posteriorly, behind scutellum with longitudinal impressions, latter rather slender, close to suture and extending posteriorly along it. Medially serrate fringe present on hind margin of tergite VII. Elytral punctation not umbilicate, smaller than on head and pronotum, more shallow, interspaces about 1/3-1/2 of puncture diameters. Bases of abdominal tergites (posterior to basal ridges) with uneven surface, segments with scattered, tiny punctures. Aedeagus as in Fig. 90, spermatheca as in Fig. 36.

ETYMOLOGY: The species is named after Dr. Lee Herman of the American

Museum of Natural History (New York), collector of part of the type series .

COMPARATIVE NOTES: This is an unusually shiny species with black body. The vertex is convex (not flat or depressed as in most other species) similar to that of P. thayerae , but the clypeus is unpunctured.

FIGS 68-73

(68-70) Parosus brasilianus sp. n.; head and pronotum (68), elytron (69), side of head (70). (71-73) P. gigantulus sp. n.; head and pronotum (71), elytron (72), side of head (73). All SEM, dorsal views. Scale bar = 0.15 mm for 70, 0.25 mm for 68-69, 73, 0.4 mm for 72, 0.5 mm for 71.

DISTRIBUTION: Currently only known from Ecuador.

BIONOMICS: Specimens were collected from foliage by fogging and by flight intercept traps.
