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.
