Type material. Holotype: ♂ from Reserva Florestal do Morro Grande [23º43’S, 46º57’W], Caucaia do Alto, Cotia, São Paulo, Brazil, 13–30 June 2002, Equipe Biota leg. (IBSP 124323)GoogleMaps  . Paratypes: 1♀, same data as for holotype (IBSP 124310)GoogleMaps  ; 1♀, Parque Ilha dos Eucaliptos [23º43’S, 46º44’W], Represa de Guarapiranga, São Paulo, São Paulo, Brazil, 1–13 April 2004, I. Cizauskas & C.R.M. Garcia leg. (IBSP 62064)GoogleMaps  ; 1♀, Ilha de Cananéia [25º00’S, 47º54’W], Cananéia, São Paulo, Brazil, 5–6 June 1976, W.R. Fontes leg. (MZSP 12685)GoogleMaps  .

Etymology. The species name honors Andre Coelho Matos (1971–2019), Brazilian singer, composer, maestro and pianist, lead singer for the heavy metal bands Viper, Angra and Shaman. A great guy that left us too soon; name in genitive case.

Diagnosis. Males of E. andrematosi  sp. nov. resemble those of E. klausmeinei  sp. nov. by the triangular shape of the TBC in the male palps ( Figs 15View FIGURES 14–18, 20View FIGURES 19–24). They are distinguished by having the RTA bent at a 90º angle, in retro- lateral view (straight in E. klausmeinei  sp. nov.) and by the MA with the same width throughout (with a widened base in E. klausmeinei  sp. nov.) ( Figs 15–16View FIGURES 14–18, 20–21View FIGURES 19–24). Females resemble those of E. brucedickinsoni  sp. nov. by the epigyne with median septum bearing an anterior scape, but are distinguished by the slender anterior base of the scape ( Figs 17View FIGURES 14–18, 22View FIGURES 19–24).

Description. Male (holotype): Prosoma and chelicerae brown; fovea darker brown; eye borders black. Legs and pedipalps pale brown. Sternum orange with pale brown margins. Labium and endites orange, distally translucent white. Opisthosoma yellowish cream colored; dorsally with brown pattern of brown spots laterally and median chevron-like marks down posterior half; ventrally with few scattered brown spots. Spinnerets orange ( Figs 10–11View FIGURES 10–13). Total length 11.8. Prosoma: 5.3 long, 4.4 wide. Opisthosoma: 6.0 long, 3.7 wide. Eye diameters: 0.35, 0.31, 0.21, 0.30; interdistances: 0.30, 0.17, 0.50, 0.50, 0.20, 0.10. Legs (4123): I: 14.0 (4.2, 2.4, 3.5, 2.9, 1.0); II: 13.9 (4.3, 2.4, 3.3, 2.9, 1.0); III: 11.5 (3.9, 1.9, 2.4, 2.5, 0.8); IV: 14.6 (4.3, 1.9, 3.4, 3.9, 1.1). Spination follows the generic pattern except metatarsi I–II p1-1-0. Palp: VTA conical, almost median; RTA single, almost 3 times longer than wide and retrolatero-distad in ventral view; TBC wider than long; MA 2 times longer than wide, arising from tegulum at 5:30 o’clock position; E arising from tegulum at 7 o’clock position ( Figs 14–16View FIGURES 14–18, 19–21View FIGURES 19–24).

Female (IBSP 124310): Coloration pattern as in male ( Figs 12–13View FIGURES 10–13). Total length 13.5. Prosoma: 5.3 long, 4.5 wide. Opisthosoma: 8.2 long, 3.7 wide. Eye diameters: 0.35, 0.30, 0.20, 0.30; interdistances: 0.33, 0.20, 0.55, 0.53, 0.30, 0.15. Legs (4213): I: 12.3 (3.7, 2.4, 3.0, 2.4, 0.8); II: 12.5 (4.0, 2.3, 2.9, 2.4, 0.9); III: 10.7 (3.3, 2.0, 2.4, 2.2, 0.8); IV: 13.5 (4.0, 1.8, 3.0, 3.6, 1.1). Spination follows the generic pattern except femur III d1-1-0. Epigyne: epigynal field as long as wide; lateral lobes converging anteriorly; median septum wider than long; anterior scape with lighter triangular region at center ( Figs 17View FIGURES 14–18, 22View FIGURES 19–24). Vulva: double helix with 6–7 turns ( Figs 18View FIGURES 14–18, 23–24View FIGURES 19–24).

Variation. Females (n = 3): total length 11.4–13.5; prosoma length 4.7–5.3; femur I length 3.5–3.7.

Distribution. Known from the state of São Paulo, Brazil ( Fig. 65View FIGURE 65).
