Parmakanthion profundum sp. nov.

( Figs 1–11 )

Description. Holotype male ( Figs 1–5 , 11 ). Integument mostly dark brown, almost black dorsally. Ventral mouthparts mostly reddish brown, with maxillary palpomeres I–III blackish with apex reddish brown, and labial palpomere II and part of III blackish. Anteclypeus reddish brown. Labrum reddish brown on posterior half, yellowish-brown on anterior half. Scape and pedicel dark brown with some areas darker reddish-brown; antennomeres III–VII with two reddish brown rings (rings darker reddish brown toward VII), one basally, another after middle; antennomeres VIII–IX reddish brown on basal half. Meso- and metatibiae with some areas dark reddish brown. Apex of ventrites 1–4 yellowish-brown.

Head. Frons minutely, abundantly punctate; with abundant yellowish-brown pubescence not obscuring integument (pubescence partially yellower close to clypeus); with a few long, erect setae close to eyes. Area between antennal tubercles smooth; with yellow pubescence not obscuring integument; area between antennal tubercles and upper eye lobes smooth, glabrous centrally, with yellow pubescence laterally; area between upper eye lobes with a few coarse punctures anteriorly, microscopically punctate on remaining surface, with yellow pubescence on coarse punctate area and close to eyes, glabrous on remaining surface; remaining surface of vertex minutely, abundantly punctate, except central area along median groove, glabrous. Area behind eyes almost smooth superiorly, more minutely punctate close to lower eye lobe; with yellow pubescence near eye, pubescent band wider superiorly, glabrous on remaining surface, including narrow band close to eye. Genae almost twice length of lower eye lobe; abundantly minutely punctate, somewhat minutely transversely striate toward ventral surface, except smooth apex; with yellow pubescent band close to eye, sparse on remaining frontal surface, glabrous on apex and toward ventral surface. Wide central area of postclypeus with bristly yellow pubescence not obscuring integument, denser on sides of its central region, and a few long, erect setae of same color interspersed. Sides of postclypeus glabrous. Labrum finely, abundantly punctate on posterior half, almost smooth on anterior half; posterior half with sparse yellowish pubescence, and long, erect pale yellow setae interspersed; anterior half almost glabrous, except narrow fringe of golden setae on anterior margin. Distance between upper eye lobes 0.29 times distance between outer margins of eyes; in frontal view, distance between lower eye lobes 0.61 times distance between outer margins of eyes. Gulamentum smooth, glabrous, except anterior area with yellowish-brown pubescence not obscuring integument.Antennae 2.3 times elytral length (from base of scape to apex of antennomere IX – missing left antenna and antennomeres X–XI of right antenna), reaching elytral apex (including apical spine of the elytra) on basal third of antennomere VI. Scape with pubescence mostly lost, but apparently yellowish-brown dorsally, and yellowish-white ventrally, not obscuring integument; antennomere III with white pubescence on lighter rings, yellowish brown centrally, brownish apically, with narrow longitudinal band of bristly yellow pubescence centrally on inner margin, and long, erect, sparse yellowish setae ventrally; antennomeres IV–VII with white pubescence on lighter areas, yellowish brown centrally, brownish apically, and long, erect, sparse yellowish setae ventrally; antennomeres VIII–IX with white pubescence on basal half, brownish on apical half, and long, erect yellowish-white setae apically. Antennal formula based on length of antennomere III: scape = 0.93; pedicel = 0.17; IV = 0.80; V = 0.65; VI = 0.58; VII = 0.58; VIII = 0.56; IX = 0.56.

Thorax. Pronotum smooth on tubercles and area between them, coarsely, sparsely punctate on remaining surface (punctures slightly more abundant close to anterior and posterior margins); glabrous on tubercles, with yellowish pubescence not obscuring integument, except irregular yellow pubescent bands and maculae on posterior half. Sides of prothorax almost smooth, with yellowish pubescence not obscuring integument. Prosternum mostly smooth; with yellowish-white pubescence not obscuring integument laterally and close to procoxal cavities (yellower close to sides of prothorax), glabrous on remaining surface. Prosternal process with short, abundant yellowish-white pubescence on anterior half, slightly longer, yellow on posterior half. Mesoventrite with abundant yellow pubescence centrally, not obscuring integument, yellowish-white laterally; mesanepisternum, mesepimeron, metanepisternum, and metaventrite with abundant yellowish pubescence not obscuring integument. Scutellum with yellowish pubescence not obscuring integument on posterocentral area, glabrous on remaining surface. Elytra. Coarsely, moderately abundantly punctate; surface irregular; with abundant yellow pubescence basally between central crest and humerus; oblique downward yellow pubescent band from apex of central basal crest to suture on basal quarter; V-shaped yellowish pubescent band close to suture on basal third (vertex of V-shaped band with white pubescence), fused with yellow pubescent band through suture by yellow band; another V-shaped yellow pubescent band on outer side of dorsal surface of posterior quarter; irregular yellow pubescence on sides, from near humerus to near apex; mostly glabrous on second longitudinal carina, with dark brown pubescent spots on most of the? tubercles and posterior gibbosity; and tuft of short blackish setae on posterior tubercle; remaining surface with yellowish-brown pubescence not obscuring integument. Legs. Femoral peduncle mostly glabrous; femoral club with abundant yellow pubescence not obscuring integument, except nearly glabrous irregular ring on posterior half. Tibiae with two yellowish-white pubescent rings, one on apex of basal third, another on base of posterior third; posterior third with bristly brownish pubescence; base with yellow pubescence dorsally, apex with narrow yellow, bristly setae, and remaining surface with brownish pubescence; ventral and lateral posterior half of metatibiae with sparse, erect yellowish setae. Metatarsomere I as long as II–III together.

Abdomen. Ventrites with yellowish pubescence not obscuring integument, yellower on apical sides of 1–3 and irregular band on sides of 2–4; apex of ventrite 5 truncate between lateral spines.

Female ( Figs 8–10 ). In addition to the generic feature of the length of the abdominal ventrite 5, it differs from male by the shorter antennae, reaching elytral apex at middle of antennomere VII, and apex of ventrite 5 concave between spiniform projections.

Paratype male. Antennal formula of based on length of antennomere III: scape = 0.87; pedicel = 0.16; IV = 0.83; V = 0.65; VI = 0.60; VII = 0.58; VIII = 0.58; IX = 0.58; X = 0.54; XI = 0.50.

Dimensions (mm) (holotype male/ paratype male). Total length, 10.05/8.45; prothoracic length, 2.00/1.65; anterior prothoracic width, 2.05/1.70; posterior prothoracic width, 2.25/1.85; maximum prothoracic width, 3.10/2.50; humeral width, 3.25/2.80; elytral length, 6.50/5.55. Paratype female: Total length, 9.95; humeral width, 2.70.

Type material. Holotype male from HONDURAS, Lempira: Cerro Las Minas, 2700 m, Camp Quetzal , 14º32’33”N, 88º42’01”W, 30.III.2018, E. van den Berghe leg. ( MZSP, formerly DHCO) . Paratypes – 1 male ( FSCA) and 1 female ( DHCO), same data as holotype .

Etymology. Latin, “ profundum ”; allusive to the country of the type-locality. Honduras was named by Christopher Columbus due to the deep water off the coast of the country. Honduras is the plural of “ hondura ”, a Spanish word that means depth (“ profundum ” in Latin). Here used as adjective nominative neuter singular of “profundus” (meaning “deep”).

Remarks. Currently, only two species of Parmenini are known from Honduras, and both belong to Echthistatus Pascoe, 1862 .
