Holotype.

Perú, Madre de Dios, BIOLAT Biological Station, Pakitza, Zone 5, Trocha Aguajal 92, 11.9427°S, 71.2926°W, 324m, 28 October 1990 (T.L. Erwin)(NMNH: BIOLAT10190, male).

Derivation of specific epithet.

The epithet " gulliveri " is a Latinized eponym, genitive case, based on the name made famous by the Irish writer Jonathan Swift in 1726, namely Gulliver’s Travels. We so name this species because of its very large size in comparison to its congeners, reminding us of Gulliver’s travels on the island of Lilliput.

Proposed english vernacular name.

Gulliver’s beauty-bearing beetle.

Diagnosis.

With the attributes of the genus Pseudophorticus , as described by Erwin (2004) and as noted above, and large-sized for the genus. Adults with fuscous dorsum and venter and shiny throughout, the elytron with fulvous subhumeral and subapical spots, legs and mouthparts testaceous, antennomeres pale to slightly infuscated. Microsculpture absent from head and pronotum, of fine isodiametric sculpticells on most of elytron, surface luster somewhat shiny and slightly aeneous in some specimens. Head multipunctate, setiferous, punctures of occiput large and deep; pronotum multipunctate and rugose, setiferous, punctures large and deep; elytron striatopunctate, striae well-impressed, intervals moderately convex and multipunctate, setiferous. Labial palpomere 3 ( Fig. 16 ) elongate and slightly acuminate (apex narrowly rounded). Pronotum lateral margin narrowly explanate throughout. Males with tarsomeres 1-3 slightly widened each with biserial rows of adhesive vestiture on ventral surface.

Description.

( Figs 16 , 17 , 18 ). Habitus: ( Fig. 16 ). Size: [See also Appendix 2] Large for the genus; ABL = 5.52-6.86 mm, SBL = 5.21-6.05 mm, TW (total width) 2.30-3.6 mm, LP = 1.10-1.29 mm, WP = 1.52-1.81 mm, LE = 3.37-4.05 mm. Color: See diagnosis above. Luster: See diagnosis above. Head ( Fig. 16 ): labrum rectangulate, sexsetose, clypeus convex with small tuberculate at middle and clearly demarcation from frons. Frons shallowly convex with moderately depressed lateral sulci, occiput shallowly domed; neck broad. Eyes large, moderately convex, longitudinal diameter coequal with length of antennomere 2 + 3; gena very short and flat. Prothorax. Pronotum ( Fig. 16 ) markedly broad and cordiform, about half as long as head (LP/LH: mean, males 1.51, females 1.49), moderately broader than long (W/L, mean: males, 1.39, females, 1.41); margin narrowly explanate with seta at anterior third and at hind angle; base convex and laterally depressed; hind angle flared laterally, slightly obtusely produced; multipunctate and rugose, setiferous, punctures large and deep. Pterothorax. Normal for tribe. Elytron about same width as pronotum (WP/TW: mean, both sexes, 0.628), moderately convex, intervals moderately convex and slightly more so laterally, interval 3 with very shallow fossae. Hind wings fully developed. Legs ( Fig. 16 ). Overall, normal for subgenus. Male front tarsus with tarsomeres 1-3 slightly dilated and each ventrally with two biserial rows of white articulo-setae. Abdominal sterna. Setation as for genus. Male genitalia ( Fig. 17 , see Fig. 61 for attribute labels). Median lobe with basal lobe about one-fifth length of shaft, basal opening small. Shaft moderately robust, sinuate ventrally, dorsally membranous except for two short sclerotized strips flanking distal part of long ostial opening; in ventral aspect constricted toward rather small hooked apex, preapically with prominent ridges lateral to a central trough, in lateral aspect, ridges converge in a small but prominently projected point. Parameres broad, apices rounded; left paramere longer than right paramere, about three quarters length of shaft (measured in left lateral aspect). Endophallus with two fields of densely packed spines. Female genitalia ( Fig. 18 ). Ovipositor with broad laterotergite (lt) and two gonocoxites (gc 1, gc 2); gonocoxite 1 spinose (short thick setae); gonocoxite 2 moderately falcate, base (b) large, broad, blade (bl) rather short, with two dorsal ensiform setae (des), ensiform setae short; without ventral preapical nematiform setae. Reproductive tract proximally with short, broad bursa copulatrix (bc), continuous at its distal end with common oviduct (co) and short bulbous bifid spermatheca (sp), latter of three bulb sections; villous canal (vc) extended from near base of spermatheca well up in common oviduct; spermathecal gland (sg) bulbous; spermathecal gland duct (sgd) long, slender, attached to spermatheca at middle bulb.

Dispersal potential.

These beetles are macropterous and probably capable of flight. They are moderately swift and agile runners.

Distribution.

( Fig. 79 ) Currently known from Ecuador and Perú, but likely more widespread.

Way of life.

See Erwin (2004) for a general description under Pseudophorticus ; some undescribed species mentioned there belong to the present new genus, not Pseudophorticus , for example, the reddish species present on leaf-cutter ant nests. This present species, Peruphorticus gulliveri , is very common running at night on bare spots on trails and in thin layers of leaf litter.
