Diagnosis

Apodrosus earinusparsus is characterized by the combination of a visible nasal plate, strongly projected eyes, a complete separation of elytral striae IX and X along their entire length, a slightly produced surface along interval X of the elytra, predominantly dark brown scales interspersed with green speckles and long, erect and apically truncate, brown and whitish setae, and a truncate mesal projection of the aedeagal apex. This species may be differentiated from A. artus by its shield-shaped body accompanied by erect elytral setae and the completely separated elytral striae IX and X. It furthermore differs from A. andersoni by its darker coloration and a longer and deeper median furrow on the head.

Body length 3.5–4.5 mm; in dorsal view ( Fig. 8A View Fig ) 2.8-times longer than greatest width which is at second third of elytra, shape escudate; dorsal outline in lateral view convex. Integument surface slightly undulated; vestiture composed of dark brown, light brown and green, iridescent (reddish) scales, with long, erect and apically truncate, brown and whitish setae. Eyes ( Fig. 8B View Fig ) 1.3-times longer than wide, strongly projected, 0.5-times width and 0.5-times length of head in lateral view, separated from anterior margin of prothorax by 0.8-times greatest diameter of eye; line of anterior margin of eyes impressed; shortest distance between eyes (in dorsal view) 0.4-times greatest width of pronotum; median furrow ( Fig. 8B View Fig ) linear, deep, extending from apical fifth of rostrum to posterior margin of eyes. Rostrum ( Fig. 8B View Fig ) 1.2-times longer than wide, mesally narrowed; epistome apically with 5 setae situated on each side; nasal plate well defined, flat. Length of rostrum in lateral view 1.4-times its basal width; antennal insertion at apical third of rostrum; scrobe curved downwards by 50°, directed posteriorly at end, not reaching anterior margin of eye, separated from it by width of scrobe. Mandibles with 2 long and 1 very short lateral seta. Antennae reddish brown; antennal scape extending beyond posterior margin of eye, not reaching anterior margin of prothorax; funicular antennomere I slightly longer than II; antennal club 0.4-times length of funicle, 2.5-times longer than wide. Pronotum ( Fig. 8A View Fig ) subquadrate, as long as wide, with greatest width at apical third; dorsal surface deeply puncturate, with curved, brown setae; posterior margin bisinuate, 1.2-times wider than anterior margin; prothorax in lateral view with dorsal outline 1.4-times length of ventral outline; scutellum oval, glabrous. Mesosternum ( Fig. 8D View Fig ) 0.6-times length of prosternum. Metasternum with lateral portions posteriorly produced (in lateral profile gradually ascending towards posterior third, thereafter descending abruptly, posterior face glabrous); distance between posterior margin of mesocoxae and anterior margin of metacoxae 0.7-times length of prosternum. Legs with profemora 1.5-times length of pronotum; tibiae with scarce, long, spiniform setae along ventral margin; claws divergent. Elytra in dorsal view ( Fig. 8A View Fig ) 1.9-times their greatest width which is 1.6-times wider than pronotum; anterior margins sinuate; humeral region 1.6-times width of posterior margin of pronotum; apex acutely rounded; in lateral view ( Fig. 8C View Fig ) with dorsal outline slightly undulated; posterior declivity gradually descending in males, distinct in females; striae IX and X completely separated along their entire length; intervals covered with scales, with a dark, transversely inverted V-shaped band basad of midpoint, surrounded by green scales and dark spots at margins; interval IV produced at basal sixth and at posterior declivity; interval IX slightly produced along basal fourth; with long, erect, apically truncate brown and yellowish setae. Venter ( Fig. 8D View Fig ) with elongate, green scales on sides, mid region almost glabrous; posterior margin of VII widely rounded; ♂: IV 1.3-times longer than V and VI jointly, as long as VII, VII with anterior margin 2.3-times wider than its length; ♀: IV 1.6-times longer than V and VI jointly, 1.6-times length of VII, VII with anterior margin 1.8-times wider than its length.

Terminalia. Male with tergum VII as long as wide; anterior margin nearly triangular, mesally narrowly rounded; posterior margin mesally slightly emarginate; posterior and marginal areas with simple setae. Tergum VIII transverse, 2-times wider than its mesal length; anterior margin mesally narrowly rounded; posterior margin mesally slightly emarginate, laterally rounded. Sternum VIII with spiculum relictum not developed. Spiculum gastrale with apodeme 1.4-times longer than aedeagus, each furcal arm semicircular. Tegmen with tegminal apodeme nearly 0.6-times length of aedeagus; tegminal plate mesally slightly posteriorly projected. Aedeagus in dorsal view ( Fig. 8E View Fig ) 3.9-times longer than its greatest width, slightly narrowed apicad of midpoint; apically narrowed, apex mesally abruptly truncate. Endophallus with a pair of lateral plates at apical fourth, with a small median sclerite and a pair of elongate, irregular lateral sclerites basad of midpoint. Aedeagus in lateral view ( Fig. 8F View Fig ) 8.4-times longer than its greatest width; apex dorsally slightly produced. Aedeagal apodemes as long as aedeagus.

Female. With tergum VII slightly wider than long; posterior margin rounded. Tergum VIII 1.4-times wider than long. Sternum VIII with lamina triangular, occupying posterior one fifth. Coxites+styli as long as lamina of sternum VIII, stylus 3.6-times longer than its greatest width, with one long apical seta. Genital chamber 0.4-times length of sternum VIII. Spermatheca ( Fig. 8G View Fig ) 1.7-times longer than wide, J-shaped; cornu roundly curved towards collum, margin between cornu and ramus slightly emarginate; ramus apically narrowed; collum apically widely rounded; surface striate.

Variation

Th e examined specimens vary primarily in size and also slightly in their coloration patterns.

Etymology

Noun in apposition. Named for the predominantly dark brown coloration interspersed with green speckles, with earinus meaning “green, the color of the spring” and sparsus meaning “strewn, sprinkled” ( Brown 1956).

Natural history

Apodrosus earinusparsus is known to occur at an elevation range of 1700–2100 m, in the central region of the Department Sud-Ouest of Haiti ( Fig. 18B View Fig ). The host plant associations remain unknown.
