Scolytodes Ferrari (Coleoptera, Scolytinae) from Ecuador: 40 new species

<p>The genus Scolytodes Ferrari is a highly diverse group of Neotropical bark beetles. Recent collecting by hand and canopy fogging in Ecuador produced many new records. Overlap in species composition between samples from the canopy and the ground was very low, and canopy fogging revealed the highest proportion of undescribed species.</p>
<p>Altogether we report records for 55 species of Scolytodes from Ecuador, including 40 species new to science: Scolytodes pseudoatratus Jordal and Smith, sp. nov., Scolytodes latipes Jordal and Smith, sp. nov., Scolytodes sloanae Jordal and Smith, sp. nov., Scolytodes samamae Jordal and Smith, sp. nov., Scolytodes otongae Jordal and Smith, sp. nov., Scolytodes chaplini Jordal and Smith, sp. nov., Scolytodes projectus Jordal and Smith, sp. nov., Scolytodes lubricus Jordal and Smith, sp. nov., Scolytodes inordinatus Jordal and Smith, sp. nov., Scolytodes cancellatus Jordal and Smith, sp. nov., Scolytodes jubatus Jordal and Smith, sp. nov., Scolytodes abbreviatus Jordal and Smith, sp. nov., Scolytodes stramineus Jordal and Smith, sp. nov., Scolytodes teres Jordal and Smith, sp. nov., Scolytodes animus Jordal and Smith, sp. nov., Scolytodes pseudoanimus Jordal and Smith, sp. nov., Scolytodes bombycinus Jordal and Smith, sp. nov., Scolytodes bisetosus Jordal and Smith, sp. nov., Scolytodes horridus Jordal and Smith, sp. nov., Scolytodes virgatus Jordal and Smith, sp. nov., Scolytodes criniger Jordal and Smith, sp. nov., Scolytodes pseudocrassus Jordal and Smith, sp. nov., Scolytodes semicrassus Jordal and Smith, sp. nov., Scolytodes pseudolepidus Jordal and Smith, sp. nov., Scolytodes semilepidus Jordal and Smith, sp. nov., Scolytodes fortis Jordal and Smith, sp. nov., Scolytodes peniculus Jordal and Smith, sp. nov., Scolytodes tristis Jordal and Smith, sp. nov., Scolytodes chrysifrons Jordal and Smith, sp. nov., Scolytodes amictus Jordal and Smith, sp. nov., Scolytodes cnesinoides Jordal and Smith, sp. nov., Scolytodes maestus Jordal and Smith, sp. nov., Scolytodes vietus Jordal and Smith, sp. nov., Scolytodes echinus Jordal and Smith, sp. nov., Scolytodes rufifrons Jordal and Smith, sp. nov., Scolytodes arcuatus Jordal and Smith, sp. nov., Scolytodes validus Jordal and Smith, sp. nov., Scolytodes sparsus Jordal and Smith, sp. nov., Scolytodes lapillus Jordal and Smith, sp. nov., Scolytodes coronatus Jordal and Smith, sp. nov. We also provide the first description of the female and a new country record for Scolytodes grandis (Schedl, 1962) (&#61;Scolytodes glaberrimus Wood, 1972 syn. nov.) and a redescription and new country record for Scolytodes pilifrons (Schedl, 1962). The total number of valid species is now 287. Additional new country records were established for Scolytodes acuminatus Wood, 1969, Scolytodes comosus Jordal and Kirkendall, 2019, Scolytodes costabilis Wood, 1974, Scolytodes glabrescens Wood, 1972, Scolytodes impressus Wood, 1969, Scolytodes nitidus (Eggers, 1928), Scolytodes striatus (Eggers, 1934), Scolytodes tucumani Wood, 2007, and from another Hexacolini genus, Pycnarthrum fulgidum Wood, 1977.</p>

Scolytodes Ferrari属为中新热带地区高度多样化的树皮甲虫类群。近期在厄瓜多尔的野外采集和树冠喷雾作业中，取得了众多新记录。树冠与地面样本在物种组成上存在极低的重叠，而树冠喷雾作业揭示了未描述物种比例之高。总计，我们报道了来自厄瓜多尔的55种Scolytodes物种，其中40种为全新科学记录：Scolytodes pseudoatratus Jordal和Smith, 新种；Scolytodes latipes Jordal和Smith, 新种；Scolytodes sloanae Jordal和Smith, 新种；Scolytodes samamae Jordal和Smith, 新种；Scolytodes otongae Jordal和Smith, 新种；Scolytodes chaplini Jordal和Smith, 新种；Scolytodes projectus Jordal和Smith, 新种；Scolytodes lubricus Jordal和Smith, 新种；Scolytodes inordinatus Jordal和Smith, 新种；Scolytodes cancellatus Jordal和Smith, 新种；Scolytodes jubatus Jordal和Smith, 新种；Scolytodes abbreviatus Jordal和Smith, 新种；Scolytodes stramineus Jordal和Smith, 新种；Scolytodes teres Jordal和Smith, 新种；Scolytodes animus Jordal和Smith, 新种；Scolytodes pseudoanimus Jordal和Smith, 新种；Scolytodes bombycinus Jordal和Smith, 新种；Scolytodes bisetosus Jordal和Smith, 新种；Scolytodes horridus Jordal和Smith, 新种；Scolytodes virgatus Jordal和Smith, 新种；Scolytodes criniger Jordal和Smith, 新种；Scolytodes pseudocrassus Jordal和Smith, 新种；Scolytodes semicrassus Jordal和Smith, 新种；Scolytodes pseudolepidus Jordal和Smith, 新种；Scolytodes semilepidus Jordal和Smith, 新种；Scolytodes fortis Jordal和Smith, 新种；Scolytodes peniculus Jordal和Smith, 新种；Scolytodes tristis Jordal和Smith, 新种；Scolytodes chrysifrons Jordal和Smith, 新种；Scolytodes amictus Jordal和Smith, 新种；Scolytodes cnesinoides Jordal和Smith, 新种；Scolytodes maestus Jordal和Smith, 新种；Scolytodes vietus Jordal和Smith, 新种；Scolytodes echinus Jordal和Smith, 新种；Scolytodes rufifrons Jordal和Smith, 新种；Scolytodes arcuatus Jordal和Smith, 新种；Scolytodes validus Jordal和Smith, 新种；Scolytodes sparsus Jordal和Smith, 新种；Scolytodes lapillus Jordal和Smith, 新种；Scolytodes coronatus Jordal和Smith, 新种。此外，我们还提供了Scolytodes grandis (Schedl, 1962)（=Scolytodes glaberrimus Wood, 1972 syn. nov.）雌虫的首次描述和该物种在新的国家记录，以及Scolytodes pilifrons (Schedl, 1962)的重新描述和新的国家记录。目前有效物种总数为287种。此外，还为Scolytodes acuminatus Wood, 1969，Scolytodes comosus Jordal和Kirkendall, 2019，Scolytodes costabilis Wood, 1974，Scolytodes glabrescens Wood, 1972，Scolytodes impressus Wood, 1969，Scolytodes nitidus (Eggers, 1928)，Scolytodes striatus (Eggers, 1934)，Scolytodes tucumani Wood, 2007以及来自另一Hexacolini属的Pycnarthrum fulgidum Wood, 1977建立了新的国家记录。
