Apochinomma parva   sp. nov.

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


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


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 ).
