Amapacylapus amapariensis Carvalho & Fontes, 1968

( Figs 1, 2, 6, 8–16 , 23 )

Amapacylapus amapariensis Carvalho & Fontes, 1968: 280 , Figs 9–10 (new species); CARVALHO (1982): 814, Figs 8–11 (description of male, male genitalia); CARVALHO & FROESCHNER (1987): 139 (list); SCHUH (1995): 19 (catalog); GORCZYCA (2006b): 12 (catalog); SCHUH (2013) (online catalog); CHÉROT & CARPINTERO (2016): 84 (record). Type material (not examined). HOLOTYPE: ♀, “Rio Amapari, T. Amapá, III–64, J.M.C.col.” (Museu Nacional, Rio de Janeiro, Brazil).

Additional specimens examined. ECUADOR: ORELLANA: J, “ Napo, Res.Ethnica Waorani, 1 km S., Onkone Gare Camp , Trans. Ent., 4 Oct. 1996, 220 m, 00°39′10″S, 76°26′00″W, T.L. Erwin, et. al.; Insecticidal fogging of mostly bare green leaves, some with covering of lichenous or bryophytic plants in terre firme forest, Lot 1737, Trans. T–8” ( USNM) ( Fig. 1) . GUYANA: POTARO- SIPARUNI: ♀, “Tumatumari, B.G. 1913” ( AMNH) ( Fig. 2) .

Diagnosis. Recognized by the following set of characters: pronotum with irregular, longitudinal yellow patches laterally and medially ( Figs 1, 2); yellow pattern on corium fully developed, without a patch on inner apical angle of endocorium, situated near apex of clavus (p7) ( Fig. 23 ); male genitalia as described below and depicted in Figs 12–22 .

Most similar to A. englemani in sharing pronotum with irregular, longitudinal yellow patches laterally and medially, and corium with fully developed yellow pattern ( Figs 23, 24 , arrows). It can be distinguished by the round corial patches (broad and elongate in A. englemani ) and the lack of the yellow patch on inner apical angle of endocorium (p7) ( Figs 23, 24 ).

Redescription. Female. (Composite description based on CARVALHO & FONTES (1968) and the specimens mentioned below). Coloration ( Figs 1–2, 6, 23 ). Dorsum dark brown with yellow and reddish areas. Head. Vertex blackish posteriorly, rest of vertex yellow, sometimes with brown or blackish, longitudinal tinge along medial sulcus; frons brown, tinged with yellow basally, medially and laterally; mandibular plate yellow red; maxillary plate blackish; buccula and clypeus yellow, tinged with brown; antennal segment I yellow; segment II brown with yellow annulation basally and sometimes also with yellow annulation near apex; segments III and IV dark brown; segments III with narrow, yellow annulation basally; labium dark brown black; segment I tinged with yellow medially. Thorax. Pronotum dark brown, broadly tinged with yellow laterally; posterior margin with two, relatively large, patches apically; collar dirty yellow. Thoracic pleura brown to dark brown with large, yellow areas; proepisternum yellow ventrally; proepimeron tinged with yellow; mesepimeron yellow ventrally and posteriorly; metepisternum with large, yellow patch on dorsal angle; metathoracic scent gland evaporative area and peritreme entirely white to pale yellow. Mesoscutum and scutellum dark brown; mesoscutum with large, yellow patch laterally; scutellum with three yellow patches: two basolaterally and one apically, medial portion of mesoscutum with yellow, longitudinal stripe along entire length. Hemelytron dark brown; corial yellow pattern fully developed except for patch situated on inner, apical angle of endocorium situated near apex of clavus (p7); yellow patches on apex of corium and embolium and on inner margin of cuneus tinged with red. Legs. Coxae dark castaneous; pro- and mesocoxae weakly tinged with yellow basally; remaining segments dark brown to black; femora and tibiae with yellow annulations.

Male. Similar to female in coloration, structure, texture, and vestiture. Male genitalia ( Figs 12–16 ). Aedeagus ( Fig. 12 ). Endosoma membranous, with serrate lobes laterally and apically; endosomal sclerite cylindrical, weakly tapering toward apex; secondary gonopore clearly present, cuplike, with dentate aperture. Left paramere ( Figs 13–15 ). Apical process thin, paramere body with inner margin arcuate and outer margin sinuate; sensory lobe well developed. Right paramere ( Fig. 16 ). Apical process sharply pointed; paramere body curved. Measurements (in mm). J / ♀ (*: holotype measurements). Body. Length: 5.50–6.20 / 6.20–6.60*, width 2.20–2.60 / 2.60*–3.00. Head. Length: 0.40–0.60 / 0.40*–0.63, width: 1.40–1.50 / 1.40*–1.48, interocular distance 0.45–0.48 / 0.50–0.52*. Antenna. Length of segment I: 0.50 / 0.40*–0.52, II: 1.60–1.70 / 1.60*–1.75, III: 2.50–2.60 / 2.80*, IV: 2.80* / 3.50–3.60. Length of segment I: 1.13, II: 1.10, III: – / 0.85, IV: – / 0.88. Pronotum. Length: 0.80–0.85 / 0.80*–0.85, width of anterior margin: 1.10 / 1.20, length of lateral margin: 0.85 / 0.85, width of posterior margin: 1.90–2.20 / 2.10*–2.30.

Biology. Collected using insecticidal fogging of mostly bare green leaves, some with covering of lichenous or bryophytic plants in terre firme forest.

Distribution. Brazil (Amapá, Amazonas) ( CARVALHO & FONTES 1968), Ecuador (this paper), French Guyana ( CHÉROT & CARPINTERO 2016), Guyana (Potaro-Siparuni) (this paper).
