Records

Without further literature records.

Diagnosis

Conapesquius brevifemur can be distinguished from C. heteracanthus , C. rectipes , and C. spinifemur due to (1) Ch bulla anterior mesal margin with spines (as in C. rectipes ) ( Fig. 5A); (2) mesotergum thickest at area II ( Figs 4E View Figure 4 , 5B); (3) Scutal area III with a paramedian pair of prominent domed-shaped tubercles (as in C. rectipes ) ( Figs 4A, C–E View Figure 4 , 5A–B, D); (4) Fe IV dorsal face with two spines on the distal third (as in C. heteracanthus ) ( Figs 4A View Figure 4 , 5A); (5) females’ ocularium armed with a pair of parallel spines ( Figs 4C View Figure 4 , 5C); (6) females’ Tr IV retrolateral face with a central apophysis (as in C. heteracanthus ).

MS D1 short, closer to C3 than A1 ( Fig. 6A–B). MS E1–E2 very reduced, located on the laterodistal flange of VP— E1 beside C1, E2 placed between C2–C3 ( Fig. 6B–C). Glans sac arising from the middle bulge on the podium, not extended as a dorsal process ( Fig. 6A–B). Stylus and its ventral process axis fused basally, forming a prominent trapezoidal-shaped pedestal above the glans ( Fig. 6A). Stylus cylindrical, bent at the distal part (forming a plateau) and armed with a set of ventral subapical spines ( Fig. 6). Stylus without any expansion or flattening, in situ reaching the distal margin of VP ( Fig. 6). Ventral process sigmoid, thinner, and as long as the stylus, with an apical flabellum ( Fig. 6B).
