Cylindridia andersoni PRENA sp. n.

Diagnosis:

Cylindridia andersoni can be recognized by the conspicuous elytral fasciae, which occur in no other known species of Cylindridia . The color pattern is less well defined in the Oaxaca specimens but the male genitalia are identical in both populations.

Description:

Derm shiny black, appendages rufescent to various degrees, prosternal spines yellowish red; white pyriform setae present on pronotal flank, metepisternum and femur, above eye, and in two elytral fasciae ( Fig. 1); rostrum slightly (males) or conspicuously longer (females) than pronotum, very slightly (female) or distinctly (male) curved throughout ( Fig. 5), lamellar process ventrad of antennal insertion not angularly projected; antennal club not longer than distal four funicular segments combined; frons with erect setae above eye; pronotum slightly wider than long, sides subtly curved in basal half, roundly constricted apically and tubulate in front; sides of aedeagus gradually converging toward base, apex truncate and medially slightly produced, base of apodemes fused with, but not subsumed in, body of aedeagus; apodeme slightly longer than body of aedeagus (Fig. 9), internal sac short, basal sclerite 2-pronged and minute, tegmen with parameroidal lobes and basal apodeme of subequal length, male sternite 9 with distal appendices unequal; total length 3.0- 3.9 mm, standard length 2.7-3.6 mm.

Distribution:

The species is known from high elevations in Guatemala and Mexico.

Plant associations:

The specimens from Guatemala were extracted from the culm of a Rhynchospora species , possibly R. macrochaeta Steudel ex Böckeler , Cyperaceae .

Epithet:

The species is named after my Canadian friend and colleague Robert S. Anderson, who found the species inside the host plant.
