Nyctantonina pteromacrotata Vélez, 2013

Nyctantonina pteromacrotata Vélez View in CoL sp. nov.

( Figures 2 View FIGURES 1 – 2 , 9–14 View FIGURES 3 – 14 )

Type material. Holotype male, Guatemala: Yepocapa, H. Elishewits, Mar.–Apr. 1945 ( AMNH).

Differential diagnosis. N. pteromacrotata differs from N. breviclasma by 1) Tegmina longest, which extend beyond the apex of the cerci; 2) Supra-anal plate with caudal margin produced and medially truncated; 3) Both subregions, R 1v and R1d, projected simultaneously over the complex R 1t +R2 and 4) The projection of the left arm (R2), with the right lateral margin deeply emarginated.

Description. General habitus as in generic description. Species of medium size ( 20 mm male), with body, legs and antennae dark brown. Pronotum and tegmina reddish brown ( Fig. 2 View FIGURES 1 – 2 ).

Male with both pairs of wings extending beyond the apex of cerci.

Supra-anal plate with caudal margin produced and medially truncated ( Fig. 9 View FIGURES 3 – 14 ); cerci long and cylindrical, with 11 segments, the last segment oval and narrower than the other segments ( Fig. 9 View FIGURES 3 – 14 ); ventrally, right paraproct straight and claw-shaped ( Fig. 10 View FIGURES 3 – 14 ). Male subgenital plate slightly asymmetric, with styles similarly shaped, with left style longer than the right style and distally located on the caudal margin ( Fig. 11 View FIGURES 3 – 14 ).

Genital sclerites: region R1 as a large and bulky structure at the caudal region of sclerite R; subregion R 1v broader than the subregion R1d, the latter as a narrow and elongated stripe extending along the caudal and the left lateral margin of R1; both subregions, R 1v and R1d, projected simultaneously over the complex R 1t +R2 ( Fig. 14 View FIGURES 3 – 14 ); this projection ending in the lateral margin of subregion R 1t. The projection of (R2) with right lateral margin deeply emarginated ( Fig. 14 View FIGURES 3 – 14 ). Apex of R2 extended beyond the caudal margin of R3. Complex R 1t +R2 located near the lower left corner of region R3, below the projection of R1d, nearly half the size of regions R3 ( Fig. 14 View FIGURES 3 – 14 ). Caudal margin of region R3 with middle projection not articulating with subregion R 1v ( Fig. 14 View FIGURES 3 – 14 ).

Measurements (mm). Body length 20; pronotum length × maximum width 4.0 × 7.7; tegmen length × width 24.2 × 8.0; interocular width 0.3; interantennal width between sockets 1.7.

Etymology. Pteron (Gr.) = wing, makrotatos (Gr.) = longest. The name refers to the long wings of this species.

Distribution. Central America ( Guatemala).
