Holotype: HL 0.707, HW 0.559, SL 0.492, WL 0.942, PL 0.237, PPL 0.172. Paratypes. (two workers): specimen one: HL 0.738, HW 0.635; specimen two: HL 0.753, HW 0.631.

Head subrectangular, with gently convex sides; mandibles in side view strongly curved ventrally; masticatory margin concave, with approximately 10 evenly spaced, extremely minute denticles; masticatory margin smoothly rounding into basal margin; dorsal surface of mandible sublucid, faintly striate, with scattered piligerous puncta; clypeus short, with broadly triangular translucent anterior lamella; antennal sockets fully exposed in face view; frontal carinae closely approximated, forming a low median keel; gena lacking lateral teeth overlapping mandible bases; entire head capsule, dorsally and ventrally, uniformly and densely punctate; eyes absent; scapes when laid back reach 3/4 distance from antennal insertions to posterolateral vertex margins; antennae 12-segmented, second funicular segment one and a half times length of first and third segment, which are subequal in length; funicular segments gradually thicken distally to longer, fusiform apical segment.

Pronotal suture present and flexible; in profile pronotal and mesopropodeal sutures very weakly impressed, pronotum and mesonotum forming very low convexities, dorsal face of propodeum long and flat, gently sloping posteriorly before rounding into short posterior face, dorsal face twice as long as posterior face; flange over metapleural gland opening forming a blunt angle; pronotum and dorsal face of mesonotum punctate, interspaces subequal in width to puncta diameters, interspaces smooth and shiny; mesopleura and propodeum more densely, finely punctate, mat; lacking metatibial gland; middle and hind tibiae each with single pectinate spur, metatibial spur larger than mesotibial spur; claws simple.

Petiole and postpetiole very small; petiolar tergite with anterior node and long sloping posterior face; petiolar sternite with deep, rounded anteroventral process; anterior juncture of petiolar tergite and sternite forming an angular notch; anterior margins of tergite and sternite produced anteriorly with carinate rims, such that petiole has an anterior pocket that encloses the narrow presclerites that articulate with the propodeum; petiolar spiracle on anterior rim of tergite, very small and difficult to see; postpetiole somewhat barrel-shaped, tergite a half cylinder, with flat semicircular anterior face above very small neck of helcium, sternite also large, with large anteroventrally projecting tooth; postpetiolar spiracle on anteromedian side of tergite, beneath juncture of anterior and dorsal face of tergite.

Type Material

Holotype worker: Costa Rica, Puntarenas Prov., Monteverde, 1300m, 10°18'N 84°48'W, July 1995, in moist forest litter (D. McKenna) [Instituto Nacional de Biodiversidad, Costa Rica]. Specimen code INBIOCRI001281138. Paratypes, all same data as holotype, each pin with 2 workers and unique specimen code: INBIOCRI001281139 [The Natural History Museum, London, U.K.]; INBIOCRI001281140 [John T. Longino, personal collection, Olympia, WA, USA]; INBIOCRI001281141 [Los Angeles County Museum of Natural History, Los Angeles, CA, USA]; INBIOCRI001281142 [Museum of Comparative Zoology, Cambridge, MA, USA]; INBIOCRI001281143 [Museu de Zoologia da Universidade de São Paulo, São Paulo, Brazil]; INBIOCRI001281144 [University of California, Davis, CA, USA]; INBIOCRI001281145 [National Museum of Natural History, Washington, DC, USA]; INBIOCRI001281146 [Naturhistorisches Museum, Basel, Switzerland]; INBIOCRI001281147 [American Museum of Natural History, New York, NY, USA]. Additional workers from the type series (all nestmates) are in 95% ethanol and have been deposited at National Museum of Natural History and stored in liquid nitrogen to preserve DNA. These workers were stored at ambient temperatures prior to deposition at USNM.

Etymology

Named for Duane McKenna, who collected the type series. It is used here as a noun in apposition and thus invariant.
