DIAGNOSIS: Recognized by body dark fuscous to black, except for two small, pale brown spots on vertex near eyes; antenna and first two pairs of legs primarily pale, metathoracic leg pale with apical half of femur reddish or reddish brown, apical 2/5 of tibia fuscous (fig. 2); metepisternum dorsal to evaporative area of scent gland without microtrichia. The dark fuscous to black hemelytron and the reddish coloration on the hind femur easily separates this species from

microtrichia are present well dorsal to the scent gland evaporative area (fig. 6C), whereas in the new species the metepisternum, dorsal to the evaporative area, is devoid of microtrichia.

brown with paler area adjacent to margin of eye; base of antennal segment I fuscous, remainder of antenna yellowish brown frequently darker apically; labium pale yellowish brown, dark fuscous at apex. Pronotum uniformly black. Scutellum black. Hemelytron with corium uniformly dark fuscous to black, cuneus slightly paler, membrane uniformly fuscous. Coxae, trochanters, fore and hind femora, and tibiae pale yellowish to pale yellowish brown, basal 60% of hind femur pale yellowish with apical 40% red to reddish fuscous, hind tibia pale yellowish, fuscous apically, basal two tarsomeres usually pale yellow, tarsomere 3 fuscous. Underside of thorax shining, dark reddish brown, evaporatorium dark reddish brown, abdomen dark reddish brown to fuscous. GENITALIA (fig. 5):
Genital segment
with bifurcate tergal process projecting from midline of dorsal margin of aperture; right side of process with short rounded tubercle, medial region of process with crest-shaped, serrate flange, base of process with short dorsal tubercle; ventroposterior margin of capsule with narrow dorsoventrally orientated ridge; distal width of subgenital plate narrow, not projecting beyond aperture of capsule.
Left paramere
C-shaped in dorsal view; without sensory lobe; diameter of paramere subequal for entire length, except slightly thickened medially; apical region bifurcate with longer ventral lobe terminating in slightly pointed apex and shorter pointed lobe.
Right paramere
elongate, twice length of left paramere; diameter of paramere slightly thickened basally and apically; apical region curved dorsally, terminating in large point and several more basal and slightly smaller points.
Phallotheca
cylindrical, 2/3 length of spiculum; aperture large, open on right side, apex, and distally on left side.
Vesica
with one large, medially thickened spiculum, situated on dorsal surface of ductus seminis; apical region of spiculum bifurcate with recurved, strongly serrate branches reaching middle of spiculum; base of spiculum with large bifurcate lobe on left side surpassing apex of secondary gonopore.
Female
: Similar to male in color and form.

DISCUSSION:
Distant’s 1893
description of
Ficinus sagittarius
, based on
six specimens
, listed a variety, ‘‘var. a. Clavus and corium black and unicolorous’’. The unnamed ‘‘variety’’ was not present at the BMNH during examination, by either of us on separate occasions, of the
three paralectotypes
(designated by
Carvalho and Dolling, 1976
). However, based on Distant’s small but revealing description ‘‘var. a’’ is conspecific

with the species here designated as
Ficinus distanti
,
n. sp.
The type locality of the Distant material is Chilpancingo,
Guerrero
, which is approximately
27 km
south of Xochilapa, the area in which our specimens were collected. Both species of
Ficinus
were collected together near Xochipala,
Guerrero
. Three additional females from the type locality, but in poor condition because of alcohol preservation, are conspecific with the
holotype
.
HOST PLANT: Unknown.
ETYMOLOGY: This species is named in honor of W. L. Distant, the well-known English taxonomist, who described the genus
Ficinus
and
its
type
species
F
.
sagittarius
.
DISTRIBUTION: Known from two localities in
Guerrero
(fig. 9).
