Diagnosis
One of two New World species of
Voconia
. Recognized by the coarsely granulose head and prothorax; wide anteocular region; morphologically ventral surface of labium with sparsely long macrosetae; buccula with lateral tubercles protruding past buccular margin; and yellow antero- and posteromedial spots on the abducted corium.
Etymology
The specific epithet is the Latin adjective ‘
mexicanus
, -
a
, -
um
’, meaning ‘from or pertaining to Mexico’, referring to the country of the
type
locality.

Description
Male
(
Figs 8

BODY LENGTH.
10.3–10.9 mm
; macropterous.
COLORATION. Head: uniformly dark brown; labium lighter than head, yellow brown. Thorax: as head; posterior pronotal lobe with posterior margin lighter; scutellum dark with brown apical spine. Hemelytron (abducted): clavus dark reddish-brown with distal yellow stripe; corium dark reddish- brown with anteromedial and posteromedial yellow spots; membrane dark with pale V-shaped marking along R and M veins; membranal veins R, M, and An
1
proximally pale. Legs: dark brown. Abdomen: dark brown, laterotergites light brown.
INTEGUMENT AND VESTITURE. Head and pronotum: coarsely granulose with sparse pubescence on setigerous tubercles; interocular region unarmed with macrosetae; antennifer with 1–3 short lateral setigerous tubercles; morphologically ventral surface of labium with sparse, long macrosetae. Thorax: anterolateral angles of pronotal collar with setigerous tubercles. Hemelytron: corium with dense, short setation. Legs: posterior row of protuberances on mid and hind femora with three large spines on distal half and two to five small spines. Abdomen: ventral surface pubescent.
STRUCTURE. Head: elongate, 1.2–1.3 times as long as wide; anteocular region about one third of head length, longer than postocular region (measured to anterior margin of neck); postocular region in dorsal view about as long as eye, lateral margins gently rounded; pedicel 1.4–1.9 times length of head width; maxillary plates ellipsoidal, adjacent to and longer than clypeus; apices of maxillary plates in dorsal view directed straight or diverging; clypeus in dorsal view narrower than maxillary plates; clypeal apex round, not narrowed; interocular glabrous markings anterolaterally curved, joined at interocular sulcus paramedially; interocular sulcus in dorsal view curved and smoothly rounded anteriorly; eye width in dorsal view narrower than synthlipsis; eye reaching ventral head margin in lateral view; ventrolateral swelling of buccula with lateral protrusion that surpasses buccular margin; labial segment I in lateral view straight, reaching or slightly shorter than posteroventral eye margin; morphologically dorsal surface of labial segment II nearly straight, about 0.4 times length of segment I. Thorax: pronotal collar in dorsal view narrow medially with anterolateral angles short, projected forward; anterior pronotal lobe about 0.5–0.6 times length of posterior pronotal lobe, lateral margins rounded; glabrous markings on pronotum thin and gently depressed; median apodeme depression of pronotum deep, circular; scutellar spine long, subhorizontal or raised; anteriad-directed process of prosternum with paramedial lobes (
Fig. 3I
); anterior margin of stridulitrum projected into small protuberance (
Fig. 3I
); proepimeron with acute protuberance on posteroventral margin. Legs: fossula spongiosa present on fore and mid legs. Abdomen: anterior margin of terga weakly carinulate; terga II and III with paired prominent longitudinal carinae, reaching about one-third of tergum III. Pygophore (
Fig. 12
): transverse bridge with rounded posterior margin; posterior region of ventral surface of pygophore in lateral view with large swelling; short median apical process sharply bent posteriorly in lateral view; lateral pygophore margin with protuberance; posterior pygophore margin with clustered macrosetae on flat margin; parameres sinusoidal, apex tapered into squarely rounded tip. Aedeagus (
Fig. 14
): endosoma almost entirely covered with spicules; apex of dorsal phallothecal sclerite rounded in dorsal view; basal plate extension about 4.3 times as long as wide.
Female
Distinguished from males by the following. Body length: about
12.2 mm
. Head: elongate, about 1.2 times as long as wide; anteocular region shorter than postocular region (measured to anterior margin of neck); with sparse, short macrosetae on setigerous tubercles and sparse pubescence on setigerous tubercles; pedicel about 1.6 times length of head width; apices of maxillary plates in dorsal view directed straight; labium lighter than head, brown; labial segment I in lateral view surpassing posteroventral eye margin. Thorax: pronotal collar in dorsal view narrow, almost absent medially; anterolateral angles of pronotum long, projected forward. Hemelytron: corium dark with thick medial yellow stripe; with dense, long macrosetae. Legs: posterior row of protuberances on mid and hind femora with three large spines on distal half and many small spines (
Fig. 4I
); fossula spongiosa absent or vestigial on mid leg.
Distribution
(
Fig. 19
)
This species is distributed in Southern Mexico and
Honduras
.
Remarks
The female from
Honduras
is considerably different from the males from
Mexico
as the description states above. We keep them as a single species until this hypothesis can be further tested with additional material. Specimen voucher UCR_ENT 00004570 was mis-labelled as collected “
4 mi
N of Cardale”, though it should be “
4 mi
N of José Cardel” as recorded by other collectors on the same trip.
