 Type material: Holotype: male from Fazenda Santa Marta, Tailândia, Pará, Brazil (02°46’33.2”S, 48°46’48.2”W), May 13–14, 2003, Equipe IPAN leg., 1♁, deposited in MPEG 10923, PBI_OON 45368. Paratypes: same data as holotype, 1♀ (MPEG 10971, PBI _ OON 45364); 1♀ (MPEG 10994, PBI _ OON 45387); Jul. 19–30, 2003, Equipe IPAN leg., 1♁ (MPEG 10918, PBI _ OON 45372); 1♁ (MPEG 10919, PBI _ OON 45374); Fazenda Rio Capim, Goianésia, Pará, Brazil (03º18’50”S, 48º28’54”W) Jun. 17, 2003, Equipe IPAN leg., 1♀ (MPEG 10991, PBI _ OON 45385).   
 Etymology. The specific name is a Latin adjective meaning excavated, alluding to the spoon-shaped female postepigastric plate.   
 Diagnosis. Males of this species resemble those of H. baherae sp. nov. and H. numerosa sp. nov. by the conductor approximately the same size of the embolus, without proximal projection and with single tip, endite’s P1 longitudinally oriented, not folded over itself, and by the absence of endite’s P3 (Figs 60C,H, 63C,H); they can be distinguished from those of H. numerosa sp. nov. by endite’s P1 directed posteriorly (Figs 66C–D) (directed anteriorly in H. numerosa sp. nov.) and from those of H. baherae sp. nov. by the endite’s P2 represented by a small acute process (Figs 66C,D) (a large bent plate in H. excavata sp. nov.). Females resemble those of H. tallitae sp. nov. and H. platnicki sp. nov. by the lack of a postepigastric scape and by the long postepigastric plate, tongue-shaped (Figs 28J, 31J). They differ by the excavated postepigastric plate, (Figs 65F–H, 66J) (not excavated in both H. tallitae sp. nov. and in H. platnicki sp. nov., Figs 28J, 31J).   
 Description. Male (PBI_OON 45368). Total length 1.45. CEPHALOTHORAX: Carapace pale orange, with Coxapopha -like pattern, pars cephalica strongly elevated in lateral view, surface of elevated portion of pars cephalica smooth, sides striated, fovea present (Figs 64B–C, 66A). Eyes ALE oval, PME oval, PLE circular; posterior eye row recurved from above, procurved from front; ALE separated by their radius to diameter, ALE-PLE separated by less than ALE radius, PME touching throughout most of their length, PLE-PME separated by less than PME radius (Fig. 64E). Sternum as long as wide, orange-brown, median concavity absent, with radial furrows between coxae I–II, II–III, III–IV, furrow wrinkled, surface smooth, without pits, microsculpture only in furrows (Figs 64D, 66B). Mouthparts: Chelicerae distal region abruptly narrowed (Fig. 64E). Labium anterior margin anteriorly projecting at middle (Fig. 66C). Endites with a median projection (mp), a P1 and a P2; mp very short, with wide base and narrow tip, directed anteriorly; P1 relatively long, directed posteriorly, anterior margin serrated. P2 very short, tip needlelike, situated anteriorly to P1 (Figs 64F, 66C–E). ABDOMEN: dorsum soft portions pale orange. Book lung covers small, very narrow. Dorsal scutum orange-brown, covering full length of abdomen, no soft tissue visible from above. Epigastric scutum not protruding. Postepigastric orange-brown, almost semicircular, covering nearly full length of abdominal length (Figs 64B, G). LEGS: yellow. GENITALIA: Epigastric region with sperm pore situated posteriorly in relation to posterior spiracles (Fig. 64G). Palp proximal segments pale orange; embolus tip not bent upwards; conductor present, without projections, as long as embolus (Figs 64G–I, 66G–I).   
 Female (PBI_OON 45387). As in male except as noted. Total length 1.49. CEPHALOTHORAX: carapace without any pattern, fovea absent (Fig. 65C). Eyes ALE circular, PME circular, PLE oval; ALE separated by more than their diameter (Fig. 65E). Sternum pale orange, furrow smooth, surface finely reticulate, microsculpture medially and in furrows. Mouthparts: Chelicerae, endites and labium pale orange. Labium rectangular, anterior margin not indented at middle (Fig. 65D). ABDOMEN: dorsum soft portions yellow. Dorsal scutum pale orange. Postepigastric scutum pale orange (Figs 65A–B, F). GENITALIA: Ventral view: postepigastric plate relatively long, tongue-shaped, concave; postepigastric scape absent; copulatory orifice slit-shaped, narrow, situated behind elevated anterior margin of posterior ventral scutum in depression. Dorsal view: anterior genitalic process with slightly recurved arms (Figs 65G–H, 66J–L).
