REVISION OF THE GENUS PHRENAPATES GRAY 1832 AND A PRELIMINARY STUDY OF THE SUBTRIBAL LIMITS OF THE SUBFAMILY PHRENAPATINAE (Coleoptera: Tenebrionidae)

<p> A revision of the Neotropical darkling beetle genus <i>Phrenapates</i>
Gray 1832 (Tenebrionidae: Phrenapatinae) was conducted. Using over 300 specimens of Phrenapates, the
genus is redescribed with its taxonomic history and classification summarized.
Lectotypes are designated for <i>Phrenapates bennettii</i> Gray 1832, <i>P.
ohausi</i> Gebien 1910, <i>P. dux</i> Gebien 1910, and <i>P. educator</i>
Gebien 1910 to stabilize species concepts. Two new species are described: <i>Phrenapates
gilloglyi</i> Rincon & Smith <b>sp. nov.</b> and <i>Phrenapates
fortunaensis</i> Rincon & Smith <b>sp. nov.</b> A total of eight species
are now recognized (<i>P. bennettii</i>, <i>P. ohausi</i>, <i>P. dux</i>, <i>P.
mandibularis</i>, <i>P. educator</i>, <i>P. latreillei</i>, <i>P. gilloglyi</i>,
and <i>P. fortunaensis</i>). Distribution maps and a key to <i>Phrenapates</i>
species are provided.</p>

In order to assess the status and
relationships of the tribes in the subfamily Phrenapatinae, a molecular dataset was constructed
for phlogenetic analyses. Nine gene regions were used: nuclear wingless (wg),
mitochondrial cytochrome b (cytb), mitochondrial cytochrome oxidase I (COI),
nuclear Arginine Kinase (ArgK), ribosomal RNA (12S, 16S, & 18S), nuclear
ribosomal 28S, and carbamoyl-phosphate synthetase domain of rudimentary (CAD).
Taxa were selected based on the availability of nucleotide sequences from the
GenBank and BOLD databases, as well as previously unpublished sequences
provided by the Smith lab. Phylogenetic analyses revealed that: (1) the
subfamily Phrenapatinae is likely monophyletic; (2) <i>Archaeoglenes</i> is
sister to the other phrenapatines in all analyses which, alongside
morphological evidence, supports the concept of the tribe Archaeoglenini; (3)
the relationship between Phrenapatini and Penetini varied between analyses,
though morphological characters used to separate the two tribes appear stable;
(4) Penetini, the most species rich tribe within the subfamily, may not be
monophyletic.
