Bioacoustics of Tolteca huahua

Description Male ( holotype ) MEASUREMENTS . Total body length 1.10, carapace width 0.46. Distance PME-PME 40 µm; diameter PME 40 µm; distance PME-ALE 20 µm; distance AME-AME 10 µm; diameter AME 25 µm. Leg 1: 1.89 (0.50 + 0.17 + 0.47 + 0.47 + 0.28), tibia 2: 0.37, tibia 3: 0.35, tibia 4: 0.60; tibia 1 L/d: 7; diameters of leg femora 0.10, of leg tibiae 0.07. COLOUR (in ethanol). Prosoma and legs monochromous ochre-yellow; abdomen slightly darker ochre-grey, with very indistinct large dorsal marks. BODY ( Fig. 36I ). Ocular area barely raised. Carapace without thoracic groove (very low indentation visible in frontal view only). Clypeus unmodified, short (clypeus rim to ALE 150 µm). Sternum wider than long (0.34/0.26), with pair of small but distinct anterior processes (~50 µm diameter at basis, ~50 µm long) near coxae 1. Abdomen globular. CHELICERAE ( Fig. 44G–H ). With pair of frontal apophyses pointing downwards, distance between tips: 50 µm; without stridulatory files. PALPS . In general possibly indistinguishable from congeners (cf. Figs 37 , 50 ); coxa unmodified; trochanter without process; femur proximally without process, distally widened but simple, slightly curved towards dorsal; femur-patella joints very slightly shifted toward prolateral side; tibia very short, with two trichobothria; tibia-tarsus joints not shifted to one side; procursus very simple ( Fig. 44I ), with distal ventral process; genital bulb large, complex, in light microscope possibly indistinguishable from congeners (cf. Figs 38D–F , 51D–F ). LEGS . Without spines and curved hairs; with slightly increased density of short vertical hairs on tibia 1 (barely visible in dissecting microscope); retrolateral trichobothrium of tibia 1 at 63%; prolateral trichobothrium absent on tibia 1; tarsus 1 with four pseudosegments, all fairly distinct. Variation (male) Tibia 1 in five males (incl. holotype ): 0.47–0.55 (mean 0.50). Female In general, similar to male ( Fig. 36J ) but sternum without pair of anterior humps; tibia 1 not with increased density of short vertical hairs. Total body length: ~1.20; tibia 1 in 12 females : 0.43–0.51 (mean 0.47). Epigynum ( Fig. 49A–D ) with short crescent-shaped anterior plate slightly protruding in lateral view; posterior plate wide, median part slightly protruding anteriorly. With distinct knob between epigynum and pedicel. Internal genitalia ( Fig. 49E–G ) with pair of strong transversal sclerites, pair of distinct sacs (receptacles?), without (or with very small?) pore plates.
