Figures 33–40, 42–47, 50–53; map 2

Katamyurus paxillus Opitz, 1997: 60 . Holotype: ♀. Nicaragua, El. 1400 m, Cerro Chimborazo , 13º02' N 85º56'W, 20 Nov. 71, Stockwell (FSCA) (Specimen point mounted, gender label affixed to paper point; support card; locality

label; FSCA acronymic label; holotype label.). Paratypes: One specimen. Nicaragua: Matagalpa: Cerro Chimborazo , 13º02' N 85º56'W, 20-XI-1971, H. Stockwell .

Diagnosis: These beetles are distinguishable from those of K. albopaniculus by the less elongate pronotum (compare figures 40, 41), and the predominantely yellow legs. In K. albopaniculus the legs are entirely black.

Moreover, in K. paxillus specimens the base antennomere of the antennal club is yellow, it is black in specimens of K. albopaniculus .

Description: Length 5.0 mm; width 1.2 mm. Form: Slender. Integument: Mostly dark brown, scape and basal antennomere of antennal club yellow; legs yellow but femora and tibiae infuscated; elytral humeral angle yellow; elytral disc with a few tufts of yellow setae. Head: Eyes convex; vertex between eyes not particularly narrow. Thorax: Side margins not subparallel, lateral tubercle prominent, disc coarsely punctate; anterior transverse depression absent; elytra, punctations somewhat rowed, with small tufts of yellow setae. Abdomen: Aedeagus (fig.53) tubular; phallic plates broad, apex modified into spring-like projections.

Variation: Length 4.3–6.0 mm; width 1.3–1.5 mm. In one specimen, from Honduras, the elytral apex is slightly elevated and setose. The humeral yellow spot varies in expression.

Natural history: Specimens were collected during March, May, June, and November. The two types were collected at 1400 m, whereas the specimen from Guatemala was collected at 950 m.

Distribution (Map 2): In addition to the type specimens I have examined five specimens from: Guatemala: Huehuetenango: 15 km N Nentón, 5-VI-1997, E. Giesbert & J. Monzón. Honduras: Olancho: Parque Nacional La Muralla, 24-27-V-1995, J, Huether; idem, 29-XI-1995, R. Turnbow; idem, 15º07'N 86º45'W, 22-

III-1995, R. Cave. Nicaragua: Matagalpa: 10 km NW Selva Negra , 12º59'N 85º54'W, 18-X-2005, 1280 m, beating, W. Opitz . Specimens are deposited in FSCA, RHTC , and WOPC.
