Litoblatta elisae sp. nov.

( Figs. 9–14 , 69 )

Holotype. Argentina. Province of Misiones : ♁, PN Iguazú (lat 25.6399S, long 54.3617W), 17/I/2006, Angrisano E. coll. ( MACN) MACN-En 34649.

Paratypes. Argentina. Province of Corrientes : ♁, Santo Tomé, (lat 28.5494S, long 56.0489W), 22/IV/2014, Villarquide M.L. coll. ( FCEN). Province of Misiones : ♁, San Pedro (lat 26.6207S, long 54.1056W), 12/ III /1957, Birabén M. coll. ( MLP).

Diagnosis. This species can be identified by the distribution of long spines in a row on the right paraproct ( Fig.10 ). R1P with a scale zone sz ( Fig. 13 , 69 ) similar to sz of L. tucumanae ( Fig. 71 ) and L. lutea ( Fig. 68 ).

Male. Measurements in mm. N= 3. PL: 2.56–3.50 (3.50); TeL: [phone] (12.80); TL: (14.74); IO: 0.70–0.80 (0.80); IOc: 0.50–0.50 (0.50); IA: 0.70–0.80 (0.70). Supra anal plate with an apical straight margin ( Fig. 9 ). The right paraproct presents a row of long spines on the internal basal margin near its base ( Fig. 10 ). Styli as usual, right stylus short, covered with spines and left stylus covered with hairs ( Fig. 11 ). Via slender and curved ( Figs. 12, 14 ). R1P with a scale zone sz placed in a bigger sclerotized area ( Fig. 13 ).

Female. Unknown.

Etymology. Dedicated to our colleague Dr Elisa B. Angrisano
