Kment, Eger, Rider 2017 [printed, yellow label]".

Diagnosis.

Coloration, structure of head, thorax and pregenital abdomen, and vestiture as in other species of the genus (see redescription of Rhyncholepta  above) except the following characters.

Apex of scutellum with anteapical black V-shaped stripe usually well developed, wide (Figure 20) to narrow (Figs 21-22), less frequently reduced to small black spot on each lateral margin at anterior end of apical V-shaped callosity (Figure 19); all color forms can be syntopic (e.g. Costa Rica, Rio Sárdinas, INBIO). Apical callosity V-shaped, robust, branches of V forming ca. one third to one half of width, tip of scutellum with distinct triangular callosity (Figs 19-22).

Male genitalia. Genital capsule in ventral view more or less constricted lateroapically (Figs 32: arrow, 34: arrow, 56: arrow, 58: arrow), posterolateral angles prominent, ca. rectangular (Figs 32, 34, 56, 58); dorsal wall at base of posterolateral angles shallowly to deeply impressed (56: arrow, 58: arrow, 67-68). Ventral rim in ventral view bilobed apically, with shallow V-shaped notch medially (Figs 32-35); hypandrial projections not visible in ventral view (Figs 32-35). Hypandrium in posterior view with pair of large lobe-like anterior projections, apices appearing acute (Figs 44, 45: ap, 46, 47: ap) and short-pointed posterior projections directed posterolaterad (Figs 45: pp, 47: pp); lateral projections not visible in ventral view but site of their attachment apparent as obtuse angle laterally on anterior projections (Figure 45: lbp, 47: lbp). Anterior hypandrial projections in most exposed (dorso-posterolateral) view smaller than in Rh. grandicallosa grandicallosa  , parabolic, with narrowly rounded apex (Figs 73: ap, 74: ap). In dorsal view, apices of anterior hypandrial projections directed anterodorsally, median outline straight (Figs 56, 57: ap, 58, 59: ap; in Rh. g. grandicallosa  convex); lateral hypandrial projections long (appearing longer than in Rh. g. grandicallosa  ), golf-club "handles" nearly parallel, suddenly curved inwards (ca. in right angle) apically (Figs 57: lp, 59: lp, 73: lp, 74: lp). Phallus (Figs 81-83) conjunctival sclerites (Figure 82: cjs) and aedeagus strongly S-shaped as in Rh. g. grandicallosa  (Figure 79; Becker and Grazia-Vieira 1971: fig. 10).

Female genitalia. Posterior edges of laterotergites VIII posteriorly as long as or slightly more prominent compared with laterotergites IX (Figure 91) (within variation of Rh. g. grandicallosa  ).

Measurements. Table 1. Measurements of holotype (in mm): Body length 13.19, body length to segment VII 11.64, head length 2.56, head width 2.41, interocular width 1.11, length of antennomeres: I - 0.84, IIa - 1.43, IIb - 2.73, III - 3.44, IV - 2.73, pronotum length 2.71, pronotum width 7.88, scutellum length 4.65, scutellum width 3.83.

Variability.

Besides the usual variation in coloration and structure within Rhyncholepta  species, we observed some variability of Rh. g. centroamericana  in the structure of the genital capsule and hypandrium, as illustrated in two males. One is from Panama, Pipeline Road (Figs 32-33, 44-45, 56-57, 67, 73; namely genital capsule slightly constricted posterolaterally [Figs 32, 56], anterior hypandrial projection longer, with apex more prominent, and median margin slightly less concave medially [Figs 45: ap, 57: ap, 73: ap]). The second male is from Costa Rica, Rancho Quemado (Figs 34-35, 46-47, 58-59, 68, 74; namely genital capsule hardly constricted posterolaterally [Figs 34, 58], anterior hypandrial projection shorter, with apex less prominent, and median margin slightly more concave medially [Figs 47: ap, 59: ap, 74: ap]). The posterolateral constric tion of the genital capsule in the specimen from Panama, Pipeline Road (Figs 32, 56: arrow) is somewhat intermediate between the typical Rh. g. grandicallosa  (see Figs 30, 54: arrow) and the population from Costa Rica, Rancho Quemado (Figs 34, 58: arrow).

Etymology.

The subspecies name is a Latin adjective centroamericanus (-a, -um) referring to its Central American distribution.

Bionomics.

Most specimens were collected by various types of light traps (UV light, mercury vapor light, metal halide light, black light) in or adjacent to dense forests. According to JE Eger, it has never been collected by hand catching, sweeping, or beating vegetation during the day or night. In Panama, three specimens were collected by "beating of forest vegetation along strips for boat navigation signs" (J Sekerka, pers. comm.) and one in "lower montane forest, [by] individual collecting" (J Hájek, pers. comm.) but without detailed information. Collection dates indicate that Rh. g. centroamericana  occurs year round, though most specimens were collected between May and October (Figure 95) ( Becker and Grazia-Vieira 1971, Arismendi and Thomas 2003; present paper).

Distribution

(Figure 98). Mexico: Chiapas (new country record); Belize (new country record); Guatemala (new country record); Honduras ( Arismendi 2002, Arismendi and Thomas 2003, both as Rh. grandicallosa  ); Costa Rica ( Arismendi 2002, as Rh. grandicallosa  ); Panama ( Becker and Grazia-Vieira 1971, Froeschner 1999, Arismendi 2002, Cambra et al. 2018, all as Rh. grandicallosa  ).

The subspecific identity of Rh. grandicallosa  population from Chocó, Colombia requires revision.
