Etymology. The species is named for Leon L. Lotz from the National Museum in Bloemfontein who contributed many specimens for this revision.
Diagnosis. Distinguished from similar congeners by shapes of procursus (distal structures,
Figs. 487, 488
; similar
S. ubicki
), bulb (processes of embolus,
Figs. 489, 490
), cheliceral armature (presence and position of proximal apophyses;
Figs. 491, 492
), and shape of epigynum (
Fig. 463
; large pockets close together; similar
S. similis
).
Male (
holotype
). Total body length 6.1, carapace width 2.0. Leg 1: 46.7 (12.5 + 0.8 + 11.7 + 19.1 + 2.6), tibia 2: 8.9, tibia 3: 7.2, tibia 4: 9.8; tibia 1 L/d: 51. Habitus as in
Figs. 428 and 429
. Carapace ochre-yellow with brown median and lateral marks, clypeus with pair of dark stripes, sternum ochre-yellow with brown pattern, leg femora and tibiae with subdistal dark rings, abdomen with dorsal and ventral pattern. Distance PME-PME 150 µm, diameter PME 160 µm, distance PME-ALE 90 µm, distance AME-AME 55 µm, diameter AME 140 µm. Ocular area slightly elevated, secondary eyes with very indistinct ‘pseudo-lenses’; deep thoracic pit. Chelicerae with proximal humps and distal apophyses (
Figs. 491, 492
), each distal apophysis provided with one modified hair (
Figs. 514, 515
). Palps as in
Figs. 447 and 448
, coxa with distinct retrolateral apophysis, trochanter barely modified, femur with retrolateral furrow with distinct proximal rim (
Fig. 516
), procursus with distinctive distal processes in dorsal view (
Fig. 488
; retrolateral view as in
Fig. 487
), bulb with distinctive complex embolus (
Figs. 489, 490
). Legs without spines, few vertical hairs, with curved hairs on tibiae and metatarsi 1 and 2; retrolateral trichobothrium on tibia 1 at 2.5%; prolateral trichobothrium present on tibia 1. Gonopore with two epiandrous spigots (
Fig. 518
); ALS with eight spigots each (
Fig. 519
).
FIGURES 487–493.
Smeringopus lotzi
. 487. Left cymbium and procursus, retrolateral view. 488. Left procursus, dorsal view. 489–490. Left emboli, prolateral and dorsal views. 491–492. Male chelicerae, frontal and lateral views. 493. Cleared female genitalia, dorsal view. Scale lines: 0.3 mm.
Variation. Tibia
1 in
10 other males: 7.0–11.0 (mean 8.9). Some specimens from eastern localities (Bloemfontein, Edenville) have identical palps but lack the proximal cheliceral humps. They are assigned tentatively.
Female. In general similar to male; triads closer together (distance PME-PME 115 µm); tibia
1 in
33 females
: 4.7–10.2 (mean 7.3). Some darker specimens with black marks proximally on femora. Epigynum a simple plate with large pockets close together (
Fig. 463
); internal genitalia as in
Figs. 464
and
493
.
Distribution. Widely distributed in central and northwestern
South Africa
(
Fig. 475
).
