description: Neorhabdopsis pecki spec. nov.   
(Figs 6A–C, 16B)  
 Type material: Holotype male: Mexico, Veracruz, 1 mi. S Huatusco, 1344 m elevation, sampled by Berlese (#171), 02.08.1969, leg. S. & J. Peck (AMNH).   
 Etymology: The specific name is given to honor the collectors of the species.   
 Description: Length: 1.5 mm. Colouration: yellow, legs and antennae light yellow.   
Head: 0.22 mm long, 0.30 mm wide; clypeus semicircular; setiferous punctation irregularly deep and dense; setae short and yellow; on average, interstices between punctures shorter than diameter of punctures; on vertex partly as wide as diameter of punctures; netlike microsculpture wide and moderately deep; on average, meshes wider than diameter of punctures; surface slightly shiny.  
Antennae slightly longer than head and half of pronotum combined; first antennomere thick and rectangular; second oblong and slightly narrower than first; third antennomere only half as wide as second and conical; following antennomeres wider than long and increasing in width; fourth slightly wider than long; sixth twice as wide as long; tenth 1.5 times wider than long.  
Pronotum: 0.30 mm long, 0.31 mm wide; widest shortly behind anterior angles; smoothly and evenly narrowed to posterior angles; posterior angles obtuse, but distinct; lateral margin moderately fine; visible in dorsal aspect except near anterior angels; setiferous punctation coarse, partly coriaceous; setae short and yellow; moderately wide midline impunctate; on average, interstices between punctures distinctly shorter than diameter of punctures, but in posterior half interstices partly much wider; netlike microsculpture deep; on average, meshes as wide as diameter of punctures; surface moderately shiny.  
Elytra: 0.19 mm long, 0.31 mm wide; widest in posterior half; shoulders smoothly curved, not rectangular; setiferous punctation large and dense; setae moderately long and yellow; on average, interstices between punctures less than half as wide than diameter of punctures; without microsculpture; surface slightly shiny.  
Abdomen with similar dense and deep punctation as on elytra; setae also moderately long and yellow.  
Protibia with five spines at outer edge and few setae on posterior face.  
Aedeagus elongate; with smoothly curved apical lobe; paramera slightly shorter than apical lobe; at apex with two long setae; endophallus narrow; with two long coils at base and one short coil at apex.  
 Diagnosis: N. pecki is the smallest species of the genus. In contrast to N. brasiliensis and N. lutzi, it is lighter yellow. Concerning the shape of the pronotum, it resembles N. brasiliensis, but the surface is shinier due to the less deep microsculpture. Compared to N. lutzi, the pronotum of N. pecki has no emargination in front of the posterior angles.
