Holcobunus Roewer, 1910 is a large genus in the family Sclerosomatidae, subfamily Gagrellinae. The generic pertinence of most of its species is unsure.

TaxonomyEdit

Type speciesEdit

SpeciesEdit

"Remarks: Both species from Brazilian Atlantic Forest (including the type species) form a very homogeneous group and probably constitute a monophyletic unit. Generic placement of species distributed outside this domain is questionable and will await on a review of those species and of other South American genera." (Tourinho & Kury 2001)

"Species of Brazilian Atlantic Forest included – Holcobunus bicornutus Mello-Leitão and Holcobunus nigripalpis Roewer." (Tourinho & Kury 2001)

DiagnosisEdit

From Tourinho & Kury (2001)

  • (1) eye mound dorsally armed with low spines with points either sharp or blunt, located on its anterior half or arranged in two parallel rows.
  • (2) first proximal nodule closer to the base of the femora (0.1-0.3/0.1-0.15/0.1-0.4/0.1-0.3 of the femur length).
  • (3) Lateral margins of supracheliceral lamina crenulate.
  • (4) Dorsal scute in male trapezoid with posterior margin convex, in female markedly pyriform.
  • (5) Pedipalpal tibia sinuous at base (Figs.12, 21).
  • (6) Femoral nodule formula: 2/5-6/2/2-3.
  • (7) Winglets (collapsible sacs) uniform narrow (longer than wide) along all its extension, borders undulated; anterior part in ventral view folding ventrally to form collar (Figs.31, 33).
  • (8) Truncus strongly sinuous dorsoventrally, slightly bent without forming definite angle at glans (Fig.27).
  • (9) Glans globous, stylus long (40% of glans length) (Figs.28, 32).
  • Character states 7-9 are unknown for H. bicornutus. Character states 2,4 and 5 are putative synapomorphies for the genus Holcobunus.

NotesEdit

Location: South America, with extralimital species from Mexico, Honduras, and Colombia, Bolivia, and others needing revision.

Tourinho & Kury, 2001 (on p. 9) say for Holcobunus iguassuensis Mello-Leitão, 1935 "is surely a member of the Pectenobunus Roewer, 1910/Acropiliops Mello-Leitão 1933 assemblage". Also, Holcobunus dentatus Roewer, 1910 was included in a list of "eight species are probably most closely related to the hitherto monotypic Jussara Mello-Leitão, 1935", but was not transferred in Tourinho-Davis & Kury, (2003). Tourinho-Davis 2004 discusses the possible placement of Holcobunus luteipalpis Roewer, 1910 in Abaetuba, concluding that re-examination of that type specimen is required.
