Neorhabdopsis pecki   spec. nov.

( Figs 6A–C View Fig , 16B View Fig )

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.
