Achates neotropicalis DISTANT, 1899:42 (description, type locality Brazil (Madeira River).

Coptochilus neotropicalis ; EGER & LATTIN, 1997:417 (synonymy, type).

Coptochilus Neotropicsis EGER et al., 2015:761 (in part, typographical error, distribution).

Type locality: Amazonas, Brazil (region of Madeira river).

General color yellow to red, with six darker longitudinal stripes distributed on pronotum and scutellum, punctation dark brown to black. Venter dark yellow to castaneus, punctation concolorous to darker than surrounding surfaces ( Figs 13-15 View Figs 10–15 ).

Head ( Figs 28-30 View Figs 16–30 ). Yellow to red, darker along posterior margin and clypeus, and sometimes laterally on mandibular plates. Mandibular plates subequal in length to clypeus, slightly elevated, apices acute to narrowly rounded, not converging in front of clypeus, separated by much more than the diameter of second antennal segment ( Fig. 28 View Figs 16–30 ).

Pronotum yellow to red, punctation dark, anterolateral margins straight to slightly convex. Each lateral stripe extending onto cicatrices anteriorly but not reaching anterior margin of pronotum, reaching posterior margin of pronotum but not extending laterally on to humeri which are generally provided with small black macule; each intermediate stripe extending from posterior to anterior margin of pronotum; middle pair of stripes narrower than and shorter than other two pairs, also not reaching anterior margin of pronotum and separated by a thin impunctate line. Scutellum yellow to red with six darker lines extending from anterior margin to about 2/3 of distance to posterior margin, not coalescing posteriorly. Pleura dark red to black mesially, lateral margins and area around coxae lighter colored. Legs pale basally becoming darker distally on femora, and on tibiae and tarsi.

Abdomen dark yellow to black, punctation dark, concolorous on darker surfaces; connexiva pale, densely and darkly punctate. Sternite VII in females slightly more than twice as long as sternite VI medially, sternite VII in males less than or equal to twice as long as sternite VI ( Fig. 14 View Figs 10–15 ).

Male genitalia. Pygophore ( Figs 43–45 View Figs 31–45 ). Ventral rim slightly sinuous ( Fig. 43 View Figs 31–45 ), almost rectilinear in posterior view ( Fig. 45 View Figs 31–45 ). Head of parameres curved, apex rounded ( Fig. 50 View Figs 46–50 ). Phallus ( Figs 66–68 View Figs 63–68 ). Conjunctival processes I surpassing conjunctival processes II and III, membranous basally, somewhat sclerotized apically; conjunctival processes II slightly curved, enlarged, apex broadly rounded, broader than conjunctival processes III. Conjunctival processes III thin, membranous basally, apices acute and lightly sclerotized, half as long as conjunctival processes II. Distal part of aedeagus sensu stricto dilated somewhat bilobed basally.

Female genitalia ( Fig. 73 View Figs 69–73 ). Laterotergites IX subtrapezoidal, anterior margin rounded; laterotergites VIII relatively broad; valvifers III moderately broad, posterior margins shallowly concave ( Fig. 73 View Figs 69–73 ).

Male measures (mm) (n=3). Total length 7.00–7.20; head: length 1.60–1.70, width 2.30–2.35; length of anteocular region 0.80–0.90; pronotum: length 2.10–2.20, width 4.15– 4.20; scutellum: length 4.20–4.40, width 4.00–4.10; length of sternites VI and VII 0.50–0.60, 1.00–1.10.

Female measures (mm) (n=1). Total length 7.30; head: length 1.70, width 2.30; length of anteocular region 0.90; pronotum: length 2.25, width 4.20; ventral length of sternites VI and VII 0.50, 1.10.

Comments. The type specimen has the intermediate stripes on the scutellum broken near the anterior margin of scutellum and a similar break near the posterior extremity of the lateral stripes. We opted not to dissect the single female specimen available to us.
