Etymology.

Description
Coloration
.—Ground color castaneous (
fig.
44
).
Head
(
fig.
45
).—Head castaneous, wider than mesonotum. Transverse piceous mark extending in a zigzag pattern between eyes. Mark begins along posterio-medial portion of eye posterior to angle extending anterior-medially across vertex almost to anterior arm of epicranial suture, turning posterio-medial encompassing lateral ocellus to posterior border of head finally turning anterior-medial to end along epicranial suture at level of lateral ocelli. Marking variable in
paratypes
particularly a decrease in posterior extension beyond lateral ocelli and width of mark. Mark reduced to small spot on medio-posterior border of lateral ocellus in one
paratype
, completely absent in another. Frons piceous anteriorly from middle of median ocellus except for coronal suture. Marking variable in
paratypes
ranging from entire frons piceous, similar to
holotype
with coronal suture also piceous, to completely castaneous frons in
paratypes
. Postclypeus slightly darker along frontoclypeal suture, small
fuscus
mark on lateral border with lorum. Postclypeus with small, medial sulcus. Anteclypeus piceous laterally. Rostrum castaneous, tip piceous reaching hind leg coxae. Lorum piceous to angle at level of mid-postclypeus. Gena with a transverse piceous line extending from anterior of mark on lorum to inner margin of eye. Marking on lora and genae may be reduced or absent in
paratypes
. Ventral head with dense silvery pile. Scape and pedicel castaneous, flagellar segments
fuscus
.
Thorax
(
fig.
45
).—Castaneous, unmarked. Lateral part of pronotal collar much reduced anterior to lateral angle of pronotal collar. Small, medial,
fuscus
spot anterior to margin of pronotal collar in some
paratypes
. Mesonotum unmarked in
holotype
but with small medial
fuscus
marks in anterior submedian sigilla which may fuse to one medial spot and/or incomplete marks along parapsidial sutures in some
paratypes
. Cruciform elevation unmarked. Long pile along wing groove. Basisternum
2
and
3
, meron
2
, and medial half of epimeron
2
and katepimeron
2
fuscus
. Ventral surface with long silvery pile.

Legs
.—Castaneous marked with
fuscus
.
Fuscus
marks on distal coxa of fore leg. Femora marked with light
fuscus
, lateral stripes disappearing in distal third of femur. Fore femur with three angled
fuscus
spines, proximal spine largest, most distal spine smallest. Distal tibiae and tarsals marked with
fuscus
. Tips of claws
fuscus
.
Tegmina and wings
(
fig.
44
).—Hyaline. Tegmina with eight apical cells, wings with six apical cells. Venation castaneous. Anal lobe along anal veins
2
and
3
and plaga grayish.
Operculum
(figs. 47, 48).—Male operculum tawny with
fuscus
lateral border covering anterior half of tympanal cavity. Lateral border angulate to posterior border border, rounded medially. Covered with long pile that also radiates from operculum around border. Opercula well separated along midline reaching middle of hind leg trochanter. Meracanthus tawny with castaneous base. Female operculum short, rounded posteriorly with long pile as in male reaching to middle of meracanthus.
Abdomen
(
figs. 44, 46
).—Dorsal abdomen castaneous, ochraceous posterior borders to tergites
3–7
and ochraceous medial spots on tergite VIII. Auditory capsule on lateral tergite
2
fuscus
. Timbal cover absent. Timbal with four ribs. Abdomen ventrally castaneous except posterior third of sternite III and posterior borders of sternites IV–VI and posterior borders of epipleurites III–VII ochraceous. Marking on female sternites expands laterally in each posterior segment. Male sternite VIII castaneous edged laterally with ochraceous. Female sternite VII deeply notched, posterior quarter ochraceous edges with castaneous. Abdomen covered with fine silvery pile.
Male genitalia
(figs.
49–51
).—Pygofer castaneous. Dorsal beak as long as anal styles. Upper lobe of pygofer expanded laterally appearing pouch-like. Basal lobe angled medially with tuft of long pile on posterior border. Uncus short, not reaching edge of anal tube with tufts of long hair laterally. Claspers broad, flat extending from basal lobe of pygofer and arching dorsally. Castaneous edged in piceous. Clasper terminus parallel to clasper base. Aedeagus tubular, pseudoparamere and endotheca longs and coiled.
Female genitalia
(figs. 52, 53).—Tergite
9
castaneous marked with
fuscus
on ventral midline and laterally. Gonocoxite IX
fuscus
. Ovipositor and ovipositor sheath about three times length of dorsal beak. Tip of ovipositor piceous.

Notes.—
The new species is most similar to
H.
ancilla
(Stål).
Herrera ancilla
differs in general body coloration with the head mainly black, the thorax green and abdomen testaceous to
fuscus
. The other Mexican species of the genus,
H.
laticapitata
Davis,
H.
lugubrina
(Stål) and
H.
lugubrina compostelensis
Davis, are generally black in coloration or possess thoracic markings (
Stål
1864
,
Davis
1938
). In addition, the genitalia of all species differ (figs.
49-51
,
Davis
1938
).
