Male: Head exposed, interocular space 1.5 mm less than the distance between antennal sockets ( 2 mm ) ( Fig. 7 ); antennae three-fourths as long as body ( Fig. 8 ); maxillary palpomeres short, the fourth shorter than the third and almost as long as the fifth. Pronotum transverse, elliptical, wider than long; anterior margin with cephalic section fissured on each side of the supra-cephalic portion of the disk (bifissate), separating the disk from the wing-like lateral sections of the pronotum, fissures V shaped ( Figs. 6, 8 ). Tegmina and wings fully developed, extending beyond margin of abdomen; hindwings complete; cubitus with incomplete branches. Antero-ventral margin of front femur unarmed, type D; tarsal segments with pulvilli, tarsal claws symmetrical, unspecialized, arolia present. Supra-anal plate transverse, bilobate, apico-lateral margin rounded, posterior margin with V-shaped mesad emargination ( Fig. 10 ); right paraproct hook-shaped, left paraproct entire ( Fig. 9 ). Subgenital plate slightly asymmetrical, styles simple ( Fig. 11 ). Genitalia as in Figs. 12–14 : left phallomere (L1) with a characteristic heavily sclerotized cleft ( Fig. 12 ), hook on the right side (R2) with a preapical incision ( Fig. 14 ), median phallomere (L2vm) with a posterior dorsal production ( Fig. 13 ). FIGURES 15–18. Schistopeltis microschistos n. sp. , female paratype: 15, pronotum (dorsal) with black arrows indicating fissure variation between the sexes; 16, habitus (dorsal); 17, supra-anal plate and cerci (dorsal); 18, subgenital plate (ventral). Arrows indicate pronotal fissure. Color: General dorsal coloration beige. Pronotum margins finely outlined with black, thicker on caudallateral angles; disk with two black spots ( Figs. 6, 8 ). Head dark chestnut; clypeus and labrum pale chestnut; areas adjacent to antennal sockets pale yellowish ( Fig. 7 ). Tegmina beige, with blackish maculae on the base of the subcosta area and anal (plical) vein; discoidal field veins blackish brown with maculae ( Fig. 8 ). Exposed mesonotal area between tegmina dark chestnut. Abdominal terga chestnut with beige lateral margins and black tubercles; abdominal sterna chestnut. Legs chestnut; tibia I–II bicolored (chestnut and beige). Supra-anal plate pale chestnut, darker along the midline; cerci with two terminal segments white ( Fig. 10 ). Female differing from male in size (see measurements), shape and color of supra-anal and subgenital plates ( Figs. 17, 18 ), shallower pronotal fissures ( Fig. 15 ), and shape of maculae on pronotum and tegmina ( Figs. 15, 16 ). Measurements (mm) (female in parentheses). Body length, 25 (27–28.5); pronotum length x width 5.3–5.5 x 10.8–11 (5.8 x 12 –12.5); tegmen length x width 23.5– 24 x 8 ( 27 x 9 ); interocular width 1.5 (1.7–1.8); interantennal sockets width 2.0 (2.1–2.2). Distribution. Department of Antioquia, Colombia . Differential diagnosis. Schistopeltis microschistos n. sp. differs from previously known species in having the fissures of the pronotal anterior margin smaller and V- shaped. The new taxon is similar to S. lizeri in having the postero-lateral pronotum angles rounded in both species. Etymology . micros (G) = small, schistos (G) = fissure. The name refers to the small size of the fissures present on the anterior margin of the pronotum.
