Hyboptera lucida Henry & Erwin sp. n. Pied humps-backed beetle Figs 7B, 8, 10C, 11
Female. French Guiana, Cayenne, Commune de Roura, Montagne des Chevaux, 4.7127°N, 52.3966°W, 90m, 17 April 2011 (S Brule, PH Dalens, E Poirier)( NMNH: ADP128638).
The epithet ‘‘ lucida' ’’ is a Latinized singular feminine adjective of lucid, for clear, referring to the translucent patch near the apex of the elytron on adult members of this species.
Proposed english vernacular name.
Pied humps-backed beetle.
With the attributes of the genus and tuberculata species group as described above and adults with only dark non-metallic markings on the pronotal disc; elytra black with 4 small pale medio-apical tubercles. Venter completely piceous. Largest adults in the genus.
(Figs 7B, 8, 10C). Size: See Appendix 1. Length (SBL) long for genus, ABL = 5.51-6.67 mm, SBL = 4.38-5.27 mm, TW = 2.36-3.25 mm.
Color: See diagnosis, above.
Luster: Without any metallic highlights, matte.
Microsculpture: Mostly isodiametric and stretched, well-impressed, cells somewhat more stretched around elytral tubercles.
Head: Rugae moderately coarse, mostly without patterned arrangement. Eye very large, hemispheric, evenly rounded. Antenna short, barely reaching humerus. Labrum rectangulate, shallowly bilobed, anterior margin slightly emarginate. Neck coarsely transversely rugose.
Prothorax: Pronotum markedly broad, disc centrally shallowly depressed with coarse angulate rugae. Lateral margins broadly explanate and evenly rounded to level of lateral seta then straight to obtuse hind angle, base medially produced and rounded posteriorly.
Pterothorax: Normal for Agrina , fully winged. Elytron intervals 3 with 10 and interval 5 with 7 prominent discal unisetiferous tubercles, interval 4 with sub-apical pale colored “lens,” other intervals moderately convex, side margin broadly explanate laterally only at middle third. Elytron broad and moderately short, much narrower in width than that of the pronotum at the broadest part, apex truncate, slightly rounded with distal corner broadly and obtusely rounded, disc not significantly convex, basal third slightly depressed. All interneurs well-impressed.
Legs: Femur dorso-ventrally moderately depressed, tibia coequal in length, more depressed; tarsus less than half the length of the tibia, fourth tarsomere markedly bilobed and with tarsal pad of setae.
Abdomen: Sparsely setiferous; normal ambulatory setae on sterna 3-5; female with two pairs of ambulatory setae on sternum 6, medial pair of setae less than the length of lateral pair; males with only the lateral pair of longer setae.
Male genitalia: Phallus (Fig. 10C) with ostium of 1/6 its length, catopic, apex very short, narrowly pointed, broadly rounded in dorsal aspect; endophallus with flagellum (obvious in illustration), flagellum not barbed. Parameres asymmetric, right very small, left larger.
Female genitalia: (Fig. 8). Ovipositor with broad triangular laterotergite (lt) and two robust gonocoxites (gc 1, gc 2); gonocoxite 1 apicolaterally not setose; gonocoxite 2 apically rounded, base (b) medium-size co-equal in width with blade (bl) which is short, blunt, with several dorsal ensiform setae (des), ventral ensiform seta absent, ensiform setae moderately short and robust; without ventral preapical nematiform setae. Reproductive tract proximally with moderately long, broad bursa copulatrix (bc), common oviduct (co) enters the bursa ventrally just anterior to bursal midlength, and long narrow corregated spermatheca (sp) distal to villous canal; spermathecal gland small, cylindrical; spermathecal gland duct (sgd) very narrow, attached to oviduct at base of its broadened portion.
These beetles are macropterous and capable of flight. They are moderately swift and agile runners. Adults of this species are attracted to light traps, and have been collected in FIT, Malaise, and SLAM traps.
Way of life.
Adults are found in January-March, May-December, in all seasons, in lowlands (13-325 m.a.s.l.) in the lowland forests of Guyane.
