Apochinomma parva   sp. nov.

( Figures 2E View Figure 2 , 3E View Figure 3 , 9C View Figure 9 , 13A, B View Figure 13 )

Etymology

The specific name is Latin for small, diminutive, referring to the size of the species.

Diagnosis

The species is easily recognizable by strongly curved basal coil of the male embolus ( Figures 9C View Figure 9 , 13A View Figure 13 ).

Male (holotype, F.C. Ziama, MRAC 214921). Measurements: CL 2.55, CW 1.39, AL 2.45, AW 1.48, TL 4.95, FL 0.15, SL 1.00, SW 0.80, AME–AME 0.08, AME–ALE 0.03, ALE–ALE 0.38, PME–PME 0.21, PME–PLE 0.22, PLE–PLE 0.90, PERW 0.92, MOQAW 0.33, MOQPW 0.41, MOQL 0.33.

Length of leg segments: I 2.20 + 0.68 + 1.98 + 1.78 + 1.30 = 7.94; II missing; III 1.93 + 0.73 + 1.70 + 1.75 + 1.03 = 7.14; IV 2.80 + 0.80 + 2.40 + 2.70 + 1.20 = 9.90.

General appearance in Figure 2E View Figure 2 , lateral view in Figure 3E View Figure 3 . Carapace elongate oval, eye region broad, tapering posteriorly to pedicel, broadest at coxa II; raised gently from eye region, with slight median depression, highest at two-thirds carapace length ( Figure 3E View Figure 3 ); surface finely granulate, covered in white feathery setae, denser on slopes in posterior two-thirds of carapace, with scattered short straight setae in anterior third; several long erect black setae on clypeus and in eye region; fovea short, broad, at twothirds carapace length; carapace deep red-brown with faint black striae. All eyes with faded black rings; AER very slightly procurved, medians larger than laterals; AME separated by distance equal to five-eighths their diameter; AME separated from ALE by one-quarter AME diameter; clypeus height equal to one and a half times AME diameter; PER strongly recurved, laterals slightly larger than medians; PME separated by distance equal to two and a quarter times their diameter; PME separated from PLE by distance slightly larger than two and a quarter times PME diameter; CW: PERW = 1.51: 1. Chelicerae orange-brown, with short straight setae on anterior surface; three teeth on promargin, median tooth largest, distal tooth tiny and indistinct; retromargin with two slightly separated teeth close to fang base, distal tooth slightly larger than proximal tooth; endites orange-brown, cream at maxillar hair tuft; labium orange-brown, cream distally; sternum shield-shaped, longer than broad, deep orange-brown; surface finely granulate, with short straight and scattered white feathery setae. Legs III missing; legs with surface of femora, patellae and tibiae finely granulate, metatarsi and tarsi finely wrinkled, covered in short straight and scattered feathery setae; femora I pale brown, with yellow dorsal and ventral stripes in distal two-thirds, remaining segments uniform yellow; femora III and IV deep red-brown, orange-brown distally; patellae III and IV yellow, with broad dorsal yellow-brown stripe; tibiae III yellow-brown and IV orange-brown, yellow distally, each with faint black dorsal stripe; metatarsi III faint yellow-brown and IV orange-brown, yellow distally; tarsi III and IV yellow. Leg spination (leg II missing): femora: I do 3, III pl 2 do 3, IV pl 2 do 3 rl 1; patellae I, III and IV with long fine distal do seta; tibiae: I plv 1 rlv 1, III pl 2 rl 2 plv 1, IV pl 2 rl 2 plv 2 vt 2; metatarsi: I plv 1 rlv 2, III pl 1 rl 1 plv 2 rlv 2 vt 3, IV pl 3 rl 3 plv 2 rlv 2 vt 3. Palpal spination: femora: do 1; patellae: pl 1; tibiae: pl 1 plv 1; tarsi: pl 2 plv 2. Abdomen pear-shaped, broad and round posteriorly, with long pedicel; dorsal scutum deep red-brown, with mottled black median stripe up to midpoint, covering entire dorsum, fused to pedicel anteriorly and epigastric plate and post-epigastric sclerites ventrally; two pairs of distinct sigilla present; dorsum uniformly covered in white feathery setae; venter creamy-grey, covered in short straight black setae; venter with orange-brown rectangular ventral sclerite, with two paired rows of tiny sclerites within it; inframamillary sclerite orange-brown, subtriangular. Male palpal segments yellow-brown with faint black mottling; tegulum pear-shaped, orange-brown, with dark red-brown insemination ducts; embolus short, with single coil, basal section strongly curved; embolus tip short, slightly curved, directed prolaterally and distally ( Figures 9C View Figure 9 , 13A, B View Figure 13 ).
