Epipharynx: with anterior edge bearing 7 or 8 short leaf-shaped setae ( Fig. 4c ) each side, setae not extending beyond anterior edge, median fraction of anterior edge bearing 3–4 pairs short stout setae, broad apical medial groove present, bearing 4 campaniform sensilla each side just laterad of groove, medial area densely invested with microtrichea from just anterior of tormae to well inside pharynx, anterior angles of tormae each bearing circular group of short setae and campaniform sensillae, membranous area mesad and posterior to this group bearing 6 campaniform sensilla each side and 1 pair on midline ( Fig. 4c ). Mandible: palmate bearing four dentae ( Fig. 4b ) and a series of peglike sensilla on interior surface; mola flattened, surface bearing transverse ridges when unworn and 1–2 short setae at base; prostheca bearing short microtrichia ( Fig. 4b ), exterior face glabrous. Maxilla ( Figs. 5a and 5b ): cardo bearing two setae at the antero-lateral edge; basistipes bearing two long and two short setae; palpus 4-segmented, basal segment small bearing 1 campaniform sensilla and 5 sensory pores, 2nd palpomere narrow at base, bearing one pair lateral setae and 2 peg-like sensilla and 4 minute sensory pores on ventral surface, large sensory pore on dorsal side, 3rd segment with ventral surface bearing basal patch of 8 sensilla and 6–7 long setae (see Fig. 5a ), dorsal surface bearing 10–13 setae ( Fig. 5b ), apical segment truncate cone, bearing 9–11 setae and 8–9 sensory pores, dorsal surface bearing short row of 8–9 tightly arranged small setae ( Fig. 5b ); mediastipes with small patch of sensilla at base of galea; galea with 13–17 short stout setae, 9 peltate, and bearing 6 sensory pores, mediastipes bearing 3–5 short setae on mesal edge; lacinia heavily invested with thickened setae. Labium ( Fig. 5c ): submentum broadly triangular bearing 16–18 long setae; mentum with transverse band of fine sensory pores, bearing 2 pairs long setae and 1 pair sensory pores each side, palpus 3-segmented, basal segment bearing 3 large sensory pores and 2–3 small sensory pores on ventral surface, 2nd palpomere bearing 4 setae and 2 sensory pores; apical segment bearing 2 setae and 4–5 sensilla, 2 apical peg-like; prementum bearing 1 pair very long setae between palpi also bearing 3 pairs long setae and 2 pairs short peg-like sensillae apically, these are surrounded by a sclerotized band bearing 2–3 sensory pores anteriorly just posterior to palp and many tightly packed stout hairs posteriorly. Hypopharynx densely invested with fine hairs ( Fig. 5c ). Pronotum weakly convex, brilliantly shining, appearing impunctate below 403, pronotal margins wide, explanate, with edge rounded as if beaded, anterior pronotal angles produced forward, covering posterior 1/3 of eye with head retracted ( Figs. 1 and 2a ), bearing one long seta slightly mesad; posterior angles bearing 1 long seta, posterior pronotal margin very weakly bisinuate. Scutellum triangular. Elytral surface shining, finely and densely punctate; humeral pronounced ( Figs. 1 and 2a ) elytral margin broad (more than the length of antennomere III at widest point), slightly concave, more coarsely punctate than elytral disc, often transparent, 88 extending almost to elytral suture, posterior 1/4th bearing evenly spaced setae. Epipleuron very broad, almost 23 antennomere III at widest point. Prosternum shining bearing fine hairs visible at higher magnifications (.253), prosternal process extending to anterior 1/2 of Mesosternum, bearing a sharp longitudinal keel its entire length ( Fig. 3 ). Mesosternum slightly concave, posterior margin deeply emarginate to receive central portion of metasternum (see Fig. 3 ). Metasternum shining, appearing glabrous but lightly invested with fine hairs, slightly convex, anterior medial margin produced anteriorly and ventrally forming a bulbous protuberance. Leg robust, meta-femur incrassate, as wide as length of tarsomeres I–III, first tarsomeres larger on pro- and mesothoracic legs, very pronounced in male; claw appendiculate. Male. Male abdominal sternum VII: bi-sinuate posteriorly, ( Fig. 3 ), widest at center, median internal apodeme clearly visible, appearing as a suture extending from the anterior of sternum VII. Male genitalia with base of Y-shaped tegmen very short.

The wider base of the dorsal median process articulates with the primary tube of the median lobe apparently from within the tube, apex of process bearing median carina. Oblique dorsal process, irregular, near triangular in shape, parallelling ventral lip. Dorsal lateral sclerite deeply concave, highly sclerotized and visibly thicker than oblique dorsal process. Apical medial sclerites irregularly triangular in dorsal view, bilobed in lateral view with endophallus slightly everted ( Figs. 6a–c ). Female. Tergum VIII ( Fig. 7d ): bearing many long setae. Sternite VIII (tignum of Konstantinov 1998 a, b): broad apically, narrowing subapically to long narrow base, apical margin medially invaginated ( Fig. 7b ). Gonocoxae (vaginal palpi of Konstantinov 1998 a, b): narrowly conical, weakly sinuate, basally obliquely truncate, each bearing 7–8 setae apically and 4 sensory pores ( Fig. 7a ). Spermatheca: with receptacle almost tubular with virtually no narrowing from head of the receptacle to the pump; pump curved, bearing a broadly spatulate sinuous flange ( Fig. 7c ), large in proportion to receptacle; proximal spermathecal duct long, well sclerotized, coiled multiple times in tight and loose loops ending just before junction of gland valve and distal spermathecal duct; distal spermathecal duct sclerotized, more than 6.53 as long as receptacle, smooth, looping to fit in abdomen; gland valve cup-shaped approximately 33 as wide as distal spermathecal duct.

Etymology. From the Latin aurora for dawn alluding to the nocturnal habits, red color and commemorative for Aurora Lauzardo who is equally brilliant and also possesses a unique combination of characteristics. Gender is feminine.

Biology. Alagoasa aurora is biologically interesting because of it is frequently collected at light, (see label data, E. G. Riley pers. comm.) Nocturnal habits are unusual for so brightly colored a beetle. Host plant and immature stages are unknown.

Remarks. Another closely related species has been collected at La Fortuna reserve in Panama´. This undescribed species is very similar to Alagoasa aurora with the exception of much larger eyes, each eye being 3/8 of the width of the head and bearing extremely large facets, in the very lightly colored pronotal margins by the iridescent greenish tinge to the body coloration. Additionally the specimen collected in Nicaragua (see other material) is significantly different from the norm that we consider to be Alagoasa aurora ; we suspect that it is a different species. It differs in having opaque and lusterless elytra, femoral apices and tibia picieous, spermatheca with pump narrow and pronounced in comparison with the receptacle and gonocoxae with base more than 43 as broad as in A. aurora .

DNA. DNA sequences were submitted to Gen-bank from a specimen collected at 1,070 m above La Selva. The sequences bear accession numbers AF545066 , D2 gene, large subunit (28S) ribosomal fragment, and AF545065 , mitochondrial Cytochrome Oxidase I fragment.
