Apochinomma tuberculata

Apochinomma tuberculata View in CoL sp. nov.

( Figures 2F View Figure 2 , 13C, D View Figure 13 )


The specific name refers to the coarse carapace texture of the species.


The species can be recognized by its relatively small size, coarsely tuberculate carapace surface, and carapace lacking a fovea ( Figure 2F View Figure 2 ).


The abdomen is separated from the carapace and the total length provided here is an estimate based on the sum of the carapace and abdomen, excluding the pedicel. The chelicerae were held very firmly together and the dentition was not investigated to avoid further damage to the holotype.

Female (holotype, Appouesso, MRAC 204310). Measurements: CL 2.68, CW 1.65, AL 2.85, AW 2.20, TL ∼5.55, FL absent, SL 0.94, SW 0.80, AME–AME 0.13, AME– ALE 0.05, ALE–ALE 0.42, PME–PME 0.27, PME–PLE 0.33, PLE–PLE 0.94, PERW 1.06, MOQAW 0.35, MOQPW 0.44, MOQL 0.35.

Length of leg segments: I 1.22 + 0.52 + 1.02 + 0.92 + 0.73 = 4.41; II 1.22 + 0.49 + 0.98 + 0.89 + 0.70 = 4.28; III 1.21 + 0.52 + 0.95 + 0.87 + 0.52 = 4.07; IV 1.58 + 0.60 + 1.32 + 1.24 + 0.65 = 5.39.

General appearance in Figure 2F View Figure 2 . Carapace oval, eye region broad, tapering posteriorly to pedicel, broadest between coxae II and III; raised gently from eye region, with shallow depression at midpoint, highest at two-thirds carapace length; surface coarsely granulate, covered in very short straight setae on tubercles, with scattered white feathery setae and scattered long erect white setae on clypeus, in eye region and at base of pedicel, sparse in midsection of carapace; fovea absent; carapace deep red, black along margins and posteriorly. All eyes with black rings; AER procurved, medians larger than laterals; AME separated by distance slightly larger than one and onefifth times their diameter; AME separated from ALE by distance approximately half of AME diameter; clypeus height slightly larger than twice AME diameter; PER strongly recurved, laterals very slightly larger than medians; PME separated by distance equal to three times their diameter; PME separated from PLE by distance slightly equal to three and three-fifths times PME diameter; CW: PERW = 1.56: 1. Chelicerae deep orange-brown with faint dark brown mottling, surface granulate, with fine short setae and scattered long erect brown setae on anterior surface; endites orange-brown, cream at maxillar hair tuft; labium orange-brown; sternum shield-shaped, longer than broad, dark orange-brown with brown mottling; surface granulate, covered in erect white curved setae. Legs finely granulate, tubercles most pronounced on femora, covered in short straight setae, with white feathery setae dorsally; femora I and II yellow, with prolateral, retrolateral and retrolateral ventral black stripes and prolateral and retrolateral stripes of white feathery setae; femora III orange-brown and IV red-brown, yellow distally, with black mottling and prolateral and retrolateral stripes of white feathery setae; patellae I and II yellow and III and IV dark yellow-brown, all with black lateral stripes, fused ventrally distally; tibiae I–III yellow and IV deep orangebrown, all with prolateral and retrolateral black stripes; metatarsi I–III yellow, with prolateral and retrolateral black stripes; metatarsi IV orange-brown, with faint black mottling; tarsi all yellow. Leg spination: femora: I pl 1 do 1, II do 1, III do 1, IV do 2; patellae with long fine distal do seta; tibiae: I plv 3 rlv 3, II plv 3 rlv 3, III plv 2 rlv 2, IV plv 2; metatarsi: I plv 2 rlv 2, II plv 2 rlv 2, III plv 1 rlv 1 vt 3, IV plv 1 rlv 1 vt 3. Palpal spination: femora: do 1; patellae: pl 1 do 2; tibiae: pl 1 do 2 plv 1; tarsi: spineless. Abdomen nearly round, with short pedicel extension; dorsal scutum large, red-brown with black mottling, extending five-sixths the length of dorsum, narrowly separated from pedicel anteriorly and epigastric plate ventrally; two pairs of distinct sigilla present; dorsum covered in short straight white setae, white feathery setae forming anterior spot, median transverse band and lateral patches behind post-epigastric sclerites; venter mottled grey, covered in scattered short straight black setae; venter with deep red-brown epigastric sclerite, post-epigastric sclerites and heart-shaped ventral sclerite situated from half the distance between epigastric groove and spinnerets up to spinnerets, apparently fused to inframamillary sclerite, forming single structure; several small oval sclerites between epigastric groove and ventral sclerite. Epigyne with short curved oblique ridges with lateral copulatory openings ( Figure 13C View Figure 13 ); copulatory ducts short, curving anteriorly and medially, entering large oval anterior ST II posterolaterally; ST II broadly connected to narrow posterior ST I ( Figure 13D View Figure 13 ).

Male. Unknown.
