Female paratype (MCZ 78876) in mm, length/width (length/ width ratio in parentheses): Leg I: trochanter 0.
As flexion of the proximal fragment will occur if the lesser trochanter remains attached to the proximal fragment, Hamilton-Russel traction may aid reduction, as it enables some degree of flexion of the distal femur, thereby aiding alignment.
9, Trochanter of legs I-III; 10, Femur of legs I-III; 11, Tibiotarso of legs I-III; 12, foot complex I-III.
Legs: With tubercles somewhat dispersed on all segments; trochanter IV unmodified; tarsal claws short, strongly curved.
Legs mainly black and yellow; all coxae black with yellowish apices; all trochanters yellow; all femora black with yellow tips; tibiae black, about distal third of fore tibia and tip of hind tibia yellow; fore tarsus yellowish but its dorsal surface darkened; mid and hind tarsi yellow but dorsal surface of last 2 tarsomeres of mid and hind tarsi darkened.
Legs dark brown, dorsal surfaces of all femora and tibiae dark grey, all coxae, trochanters and tarsi brown.
Palpal coxae and trochanters dark orange, more distal segments orange; coxae with few median and posterior tubercles, trochanters with few posterior tubercles; coxae with long, white setae anteriorly, without thickened white setae posteriorly; tibiae with short, stiff setae but without tubercles.
30 mm), each leg of each specimen with 49-50 sensilla, without natatory sensilla; coxae with prominent anterior suture, 22-23 sensilla, each with robust anteroventral sensilla; trochanters arcuate ventrally, 7 sensilla; femora with 13 sensilla on each leg and anteroventral spinulae; tibiae and tarsi each with ventral spinulae and 7 sensilla; tarsal claw length increasing posteriorly; posterior tarsal claws about 1.
verrucosum may be distinguished from those of most other Leiobunum species in that the femur of leg I is shorter than the length of the body and the trochanters and ocularium are dark and contrast with dorsum and pedal coxae.
Coxae with prominent anterior suture, procoxa glabrous on anteroventral surface, meso- and metalegs each with robust anteroventral sensillum; trochanters arcuate ventrally, proximal region (1TR) with dorsal sensillum, distal region (2TR) with three anterior, two ventral, and two posterior sensilla; femora with small spinulae between distal anteroventral sensilla, profemeral dorsal sensilla on proximal 2/3 of length; tibiae and tarsi with ventral spinulae (combs) and lacking natatory sensilla; anterior pro- and mesotarsal claws longer than posterior, metatarsal claws subequal.
Legs bicoloured, coxae black, trochanters brownish, femora and tibiae mainly black, partly yellow at tips.
The distal regions (2TR) of trochanters were moderately constricted just beyond the annular line and then distended ventrally (Fig.
