Lacronia ceci Kury & Orrico, 2006: 149, figs 1–12.

Diagnosis

Lacronia ceci can be differentiated from the other species of the genus by the following combination of characters: 1) ocularium convex with medial depression (in frontal view) (Kury & Orrico 2006: fig. 3); 2) ocularium height (in lateral view) twice more prominent than the eyes diameter (Kury & Orrico 2006: fig. 2); 3) ocularium with a pair of domed tubercles (Kury & Orrico 2006: fig. 3); 4) mesotergum areas I–IV with pale-colored tubercles contrasting with its background (Figs 4A, 10B); 5) mesotergum area I with two pairs of conspicuous tubercles (Fig. 4A); 6) mesotergum area II of th with prominent tubercles organized in an anterior pair and four posterior pairs (Fig. 4A); 7) mesotergum area III with a paramedian pair of subconical apophyses (Figs 4A, 10B); 8) Fe IV dorsal face unarmed (Kury & Orrico 2006: fig. 9); 9) Mt IV unarmed on the dorsal face (Kury & Orrico 2006: fig. 10).

Description

See Kury & Orrico (2006) for the extensive description and illustrations. We included a picture of a ♂ in vivo (Fig. 10B). Herein, we provide a redescription of the ♂ (MNRJ 6945ꜝ) genitalia based on its SEM picture.

MALE GENITALIA (Fig. 11A–D). VP slightly divided in a distal part rectangle-shaped with latero-apical flaps, and a proximal part elliptical (Fig. 11A, C). VP ventral surface entirely covered with microsetae of type 1 (Fig. 11C). All macrosetae inserted on the ventro-lateral face of VP (Fig. 11A–C). MS A1–A3 cylindrical, thick, and acuminate, forming a triangle (A1 on the basal portion of the distal part, A2–A3 on the proximal part, A2 placed ventralmost) (Fig. 11A–C). MS B1 small, inserted ventrally, close to A2 (Fig. 11C). MS C1–C3 similar to the MS A, forming a triangle (C2 ventralmost) on the distal third of VP (Fig. 11A–C). MS D1 small, placed in mid distance between A1 and C3 (Fig. 11A–B). MS E1–E2 small, on the distal flange of VP – E1 between C1–C2, E2 close to C3 (Fig. 11C). Glans sac arising from the middle bulge on the podium, not extended as a dorsal process (Fig. 11–B). Stylus and its ventral process axis fused basally, forming a prominent pedestal (Fig. 11B, D). Stylus cylindrical, sub-straight (apex slightly bent ventrad), inserted on pedestal forming a 45º angle (Fig. 11B, D), without conspicuous head, with a few small sub-distal tiny spines on dorsal and ventral faces (Fig. 11A–D). Ventral process of similar length as stylus, almost straight, with an apical flabellum curved ventrad (Fig. 11A–D). Flabellum scallop-shaped with serrulations, measuring about 40% length of the ventral process stem (Fig. 11A–D).
