Antennaeantennae:
paired, segmental appendages, borne one on each side of head, functioning as sense organs and bearing a large number of sensilla.
10-segmented with a distinct, 1-segmented club. Antennal setation sparse. Subantennal groovessubantennal groove:
groove or concavity lying below the antennal insertion and housing the base of the antenna. Placed between the eye (if present) and the mandibular articulation, and sometimes extends below or behind the eye.
absent. Eyes large, well-developed, finely faceted. Pronotal discpronotal disc:
the area of the pronotum which is visible dorsally and usually delimited laterally by the two lateral carinae. Contrasted with the paired pronotal hypomera, which extend onto the ventral surface.
convex with central depression, with two parallel, longitudinal carinaecarina:
an elevated ridge or keel, not necessarily high or acute.
. Pronotal lateral margins widest anteriorly, distinctly explanateexplanate:
spread out and flattened; applied to a margin.
. Procoxal cavitiesprocoxal cavities:
external closure: Externally closed when the postcoxal processes of the hypomera meet the prosternal process or meet one another.
open. Metacoxaemetacoxae:
the coxae of the metathorax.
narrowly separated, separation less than metacoxal length. Tarsal formulatarsal formula:
the number of tarsomeres on the fore, mid, and hind tarsi, respectively.
4–4–4. Dorsum lacking obvious pubescencepubescence:
short, fine, soft, erect hair or down.
(if visible, then not distinct).
The genus Paha is similar in general appearance to the other genera with 10-segmented antennaeantennae:
paired, segmental appendages, borne one on each side of head, functioning as sense organs and bearing a large number of sensilla.
and a 1-segmented club that lack a subantennal groovesubantennal groove:
groove or concavity lying below the antennal insertion and housing the base of the antenna. Placed between the eye (if present) and the mandibular articulation, and sometimes extends below or behind the eye.
, including Synchita and Endeitoma. The genus Synchita differs in lacking pronotal carinaecarina:
an elevated ridge or keel, not necessarily high or acute.
, lateral pronotal margins widest at middle and not as distinctly explanateexplanate:
spread out and flattened; applied to a margin.
, and the dorsal surface with short, bristle-like setaeseta:
a sclerotized, hairlike (or scalelike) projection of cuticula arising from a single trichogen cell and surrounded at the base by a small cuticular ring.
or with strongly curved, flattened, multi-colored elytral setaeseta:
a sclerotized, hairlike (or scalelike) projection of cuticula arising from a single trichogen cell and surrounded at the base by a small cuticular ring.
. Endeitoma differs in having a long third antennal segment (at least twice as long as segment 4), pronotal discpronotal disc:
the area of the pronotum which is visible dorsally and usually delimited laterally by the two lateral carinae. Contrasted with the paired pronotal hypomera, which extend onto the ventral surface.
lacking carinaecarina:
an elevated ridge or keel, not necessarily high or acute.
, lateral pronotal margins distinctly denticulatedenticulate:
set with little teeth or notches.
, and a dorsal pubescencepubescence:
short, fine, soft, erect hair or down.
consisting of thin, fine, hair-like setaeseta:
a sclerotized, hairlike (or scalelike) projection of cuticula arising from a single trichogen cell and surrounded at the base by a small cuticular ring.
. In Paha, the pronotal discpronotal disc:
the area of the pronotum which is visible dorsally and usually delimited laterally by the two lateral carinae. Contrasted with the paired pronotal hypomera, which extend onto the ventral surface.
has two parallel, longitudinal carinaecarina:
an elevated ridge or keel, not necessarily high or acute.
, the lateral margins are widest anteriorly, distinctly explanateexplanate:
spread out and flattened; applied to a margin.
, antennal segment 3 is not distinctly elongate, and the dorsal pubescencepubescence:
short, fine, soft, erect hair or down.
is minute or lacking.

Paha laticollis has been collected from under the bark of dead oaks.
Abundance: Uncommon.
