Extraordinarius klausmeinei Rheims, 2019

Figs 24−30

Extraordinarius klausmeinei Rheims, 2019: 92 , figs 40−49 (♂ holotype from BRAZIL: Espírito Santo: Conceição da Barra, Parque Estadual de Itaúnas (‑18.4167, ‑39.7000), 15 December 2002 − 06 March 2003, Equipe Biota leg., deposited in IBSP 60005).

Additional material examined. BRAZIL: Espírito Santo: ♀, Linhares [‑19.1500, ‑400667], 9−15 January 2012, J.P.P. Pena Barbosa leg. ( IBSP 249601 ) .

Note. Despite not having found males and females in the same locality, I feel confident that this is indeed the female of E. klausmeinei . Coloration pattern is very similar to that of the male and both specimens were collected in northern Espírito Santo, north of the Doce River. Additionally, specimens belonging to the same species and found far apart from one another are a common occurrence for the genus, as can be seen in Fig 31 .

Diagnosis. Males of E. klausmeinei resemble those of E. andrematosi ( Rheims 2019: figs 19−20) by the palps with triangular TBC. They are distinguished by the RTA distally flattened and almost straight in retrolateral view ( Rheims 2019: fig. 47) (bent at a 90º angle in E. andrematosi ) and by the MA with a widened base ( Rheims 2019: fig. 46) (same width throughout in E. andrematosi ). Females resemble those of E. andrematosi ( Rheims 2019: figs 22−24) and E. brucedickinsoni ( Rheims 2019: figs 37−39) by the epigyne with an anterior scape on the MS. They are distinguished from those of E. brucedickinsoni by the narrow anterior part of the scape, less than a third of the scape width (wider, exceeding half the scape width in E. brucedickinsoni ) and from those of E. andrematosi by the grooved MS and LL not reaching anterior lateral margins of the scape (MS smooth and LL reaching anterior lateral margins of the scape in E. andrematosi ) ( Fig. 24 ).

Description. Male: see Rheims 2019: 92, figs 40−49.

Female (IBSP 249601): Prosoma brown, with lighter margins; eye borders black. Chelicerae brown. Legs and palps brown, slightly lighter than prosoma. Labium brown. Endites brown, distally pale brown. Sternum brown with darker margins. Opisthosoma brownish yellow; dorsally with irregular‑shaped brown marks scattered laterally and along margins of cardiac mark and six faint median chevron‑like marks down posterior half; ventrally with median V‑shaped brown mark and irregular brown marks laterally. Spinnerets brown, distally lighter ( Figs 27−28 ). Total length 16.5. Prosoma 6.3 long, 5.1 wide. Opisthosoma 9.4 long, 5.9 wide. Eyes: diameters: 0.45, 0.38, 0.23, 0.36; interdistances: 0.34, 0.30, 0.65, 0.60, 0.23, 0.06. Legs (4213): I: 15.0 (4.5, 2.9, 3.6, 2.9, 1.1); II: 15.2 (4.7, 2.9, 3.5, 3.0, 1.1); III: 12.6 (4.1, 2.2, 2.7, 2.6, 1.0); IV: 15.9 (4.8, 1.9, 3.6, 4.2, 1.4). Epigyne: EF slightly longer than wide; LL gently converging anteriorly; MS as long as wide; anterior scape hand fan‑shaped with jagged posterior margin ( Figs 24 , 29 ). Vulva: double helix with ten turns; packed structures gently converging towards each other anteriorly; FD postero‑mediad ( Figs 25−26 , 30 ).

Distribution. Known from Espírito Santo, southeastern Brazil ( Fig. 31 ).
