Neorhabdopsis lutzi   spec. nov.

( Figs 7A–C View Fig , 16C View Fig )

Type material: Holotype male: Panama, Barro Colorado, C.Z., Nov. 1930, leg. F.E. Lutz ( AMNH).  

Paratypes: 2 males, 3 females, with same data as holotype ( AMNH, UIC)   .

Etymology: The specific name is given to honor the collector of the species.

Description: Length: 1.7 mm. Colouration: Yellow; legs and antennae slightly lighter yellow.

Head: 0.19 mm long, 0.33 mm wide; fore-head semicircular; setiferous punctation dense and deep; on average, interstices between punctures half as wide as diameter of punctures; remains of netlike microsculpture; surface moderately shiny.

Antennae slightly longer than head and half of pronotum combined; first antennomere rectangular; second oval; third conical and slightly narrower than second; following antennomeres wider than long and increasing in width; fourth antennomere slightly wider than long, nearly quadrate; tenth antennomere 1.5 times wider than long.

Pronotum: 0.32 mm long, 0.39 mm wide; widest in the middle; slightly narrowed to anterior angles; in posterior half more strongly narrowed and with emargination in front to posterior angles; posterior angles distinct; lateral margin fine; in dorsal aspect, visible throughout its total length except shortly behind anterior angles; setiferous punctation large and coarse; on average, yellow setae twice as long as diameter of punctures; on average, interstices between punctures less than half as wide as diameter of punctures; narrow irregular midline impunctate; without microsculpture; surface moderately shiny.

Elytra: 0.29 mm long, 0.39 mm wide, widest in posterior third; setiferous punctation as large and coarse as on pronotum and with similar setae; without microsculpture; surface moderately shiny. Abdomen with similarly large punctation as on pronotum and elytra; punctation even denser than on elytra.

Protibia enlarged, but relatively slender; outer edge with five fine spines and few setae.

Aedeagus thick; apical lobe in rectangular angle to basal lobe; paramera shorter than apical lobe and with long apical seta; endophallus with several coils in middle, straight apical part, and irregular coils at lateral part.

Diagnosis: The species can be easily separated from the two other described species by the distinct emargination in front of the posterior pronotal angles.
