description: Ochetostethomorpha secunda J.A. Lis & B. Lis, new species
(Figs. 1 a, 2b, 5a, 6a, 7a)
Diagnosis. The two specimens of the new species differ morphologically from those of O. nollothensis by their different body sizes (body length/width ratio about 1.6–1.7 in O. secunda, about 1.9 in O. nollothensis; pronotum width/length ratio about 1.95 in O. secunda, about 2.14 in O. nollothensis), their ocular index (2.0 in O. secunda, 2.13–2.25 in O. nollothensis), and the shape of the membrane (margins distinctly narrowing in O. nollothensis — Fig. 2 a; margins broadly rounded in O. secunda — Fig. 2 b).
Because both species are known only from a limited number of specimens, their morphological variability has not been characterized. Therefore, as usual for Cydnidae, the most reliable characters separating both species are those relating to male genital structures.
These two species differ by the shape of the genital capsule (O. nollothensis —Fig. 5b, O. secunda —Fig. 5a; dorsal view), the shape of the paramere (sensory lobe apically broadly rounded in O. nollothensis —Fig. 6b, apically narrowed in O. secunda —Fig. 6a; hypophysis digitate, almost straight in O. nollothensis —Fig. 6b, clawlike, apically recurved in O. secunda —Fig. 6a), the shape of the conjunctival appendages of aedeagus (first conjunctival appendage in O. nollothensis —Fig. 7b, in O. secunda —Fig. 7a; second conjunctival appendage apically sharpened in O. nollothensis —Fig. 7b, apically with two distinct teeth in O. secunda —Fig. 7a).
Description. Body almost black with blackish brown tinge (Fig. 2 b); lateral parts of its dorsal surface, the antennae and tarsi brown. Head 1.19 times as broad as long, its dorsal surface densely punctured; paraclypei distinctly longer than clypeus and joined in front of it; rostrum short, reaching the prosternum, lying in a deep sulcus between prosternal carinae; eyes blackish brown with reddish tinge, ocular index 2.0; ocelli very small, almost indistinct, reddish brown; antennae five-segmented, 3rd segment 1.43 times longer than the 2nd. Pronotum 1.95 times as broad as long, puncturation and sculpture of its dorsal surface as in O. nollothensis, but transverse and longitudinal depressions slightly deeper than those of the preceding species; callal area slightly elevated. Scutellum 1.2 times as long as broad; its sculpture and puncturation as in O. nollothensis. Mesocorium with ovate ochraceous spot; membrane whitish with pale brown marks, veins blackish brown, distinctly visible. Legs blackish brown, tarsi brown. Male genitalia: paramere with apically narrowed sensory lobe and claw-like, apically recurved, broadened basally hypophysis (Fig. 6a); first conjunctival appendage of aedeagus almost the same width along its entire length (Fig. 7a), the second conjunctival appendage of aedeagus with two distinct teeth apically (Fig. 7a); shape of the genital capsule as in Fig. 5a.
FIGURES 5–7. Male genitalia. 5a, 6a, 7a, Ochetostethomorpha secunda; 5b, 6b, 7b, O. nollothensis; 5a–b, genital capsule, dorsal view, arrows show different shape of the outer margin; 6a–b, left paramere, ventral view; 7a–b, conjunctival appendages of aedeagus (first appendage, at the top; second appendage, at the bottom), arrows show different shapes of their apical parts. Photographs by B. Lis.
Measurements (in mm). Body length 3.35; body width 2.00; head length 0.76; head width 0.90; pronotum length 1.00; pronotum width 1.95; scutellum length 1.40; scutellum width 1.18; antennal segments (I–V): 0.16: 0.14: 0.20: 0.24: 0.32.
