Herrera coyamensis sp.n.

( figs. 44 –53)

Type material.— Holotype male: “ MEXICO: Veracruz, Lake Catemaco , "Coyame", 5–VII–63, R.E. Woodruff, blacklight” ( FSCA). Paratypes: 1 male and 2 females same data except 1–VII–1963 (male and 1 female FSCA, 1 female AFSC), 3 males and 2 females same data except 2–VII–63 (1 male and 1 female FSCA, 2 males and 1 female AFSC), 2 females same data except 3–VI–1963 (1 FSCA, 1 AFSC).

Etymology. The species is named for the region where the specimens were collected, “Coyame” near Lake Catemaco, Veracruz.

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.

Measurements (in mm).— Males (n=5), mean (with range) given for available specimens. Length of body: 12.69 (12.10–13.48); length of fore wing: 15.42 (15.00–15.96); width of fore wing: 5.69 (5.50–5.88); length of head: 2.38 (2.22–2.48); width of head including eyes: 4.38 (4.38–4.58); width of pronotum including suprahumeral plates: 3.86 (3.74–3.94); width of mesonotum: 3.72 (3.64–3.74). Females (n=6), mean (with range) given for available specimens. Length of body: 13.86 (12.00–15.00); length of fore wing: 16.11 (14.40–17.30); width of fore wing: 5.74 (5.14–6.14); length of head: 2.36 (2.16–2.68); width of head including eyes: 4.66 (4.58–4.72); width of pronotum including suprahumeral plates: 3.99 (3.76–4.22); width of mesonotum: 3.71 (3.54–4.00).

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).
