Nyctantonina breviclasma Vélez View in CoL sp. nov.
( Figures 1 View FIGURES 1 – 2 , 3–8 View FIGURES 3 – 14 )
Type material. Holotype male, Guatemala: Alta Verapaz, 57.6 km. N. El rancho on new Coban Highway, 1464 m, Erwin and Hevel, 30 May. 1973 ( USNM). Paratypes: Mexico: two males, Chiapas, La Trinitaria, L.A. Kelton, Aug. 1969 ( CNC).
Differential diagnosis. N. breviclasma differs from N. pteromacrotata by 1) Tegmina shortest, which slightly surpassing apex of the cerci; 2) Supra-anal plate with caudal margin produced and rounded; 3) Only the subregion R1d projected over the complex R 1t +R2 and 4) The projection of the left arm (R2), with convex right lateral margin.
Description. General habitus as in generic description; medium size (19 mm male), with body, legs and antennae dark brown. Pronotum and tegmina reddish brown ( Fig. 1 View FIGURES 1 – 2 ).
Male with both pairs of wings slightly surpassing apex of the cerci.
Supra-anal plate with caudal margin produced and rounded ( Fig. 3 View FIGURES 3 – 14 ); cerci long and cylindrical, with 11 segments, the last segment oval and narrower than the other segments ( Fig. 3 View FIGURES 3 – 14 ); ventrally, right paraproct straight and claw-shaped ( Fig. 4 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. 5 View FIGURES 3 – 14 ).
Genital sclerites: region R1 as a large and bulky structure at the base 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; only the subregion R1d projected over the complex R 1t +R2 ( Fig. 8 View FIGURES 3 – 14 ); this projection ending in the lateral margin of subregion R 1t. Projection of the left arm (R2) with convex right lateral margin ( Fig. 8 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 region R3.
Caudal margin of region R3 with a middle projection articulating to subregion R 1v ( Fig. 8 View FIGURES 3 – 14 ).
Measurements (mm). Body length 19; pronotum length × maximum width 5.0–5.2 × 8.5–9.0; tegmen length × width 16.8–19.0 × 7.2–8.2; interocular width 0.3; interantennal width between sockets 1.0–1.2.
Etymology. Brevis (L) = short, klasma (Gr) = fragment, piece. The name refers to the short right arm (R 1t) of the complex R 1t +R2, which only reaches one-fifth the length of the right arm (R2).
Distribution. Central America ( Guatemala, Mexico).
