Cylindridia latisquama PRENA sp. n.

Torcus sanguineus Hustache, 1939: 117 (partim)

Cylindridia sp. A ; Prena (2006: 197)

Diagnosis:

Cylindridia latisquama is very similar to the equally rufous (and sympatric) C. sanguinea , and both species were represented in the type series of the latter. The simplest way to separate the two species is the dorsal vestiture, which consists of wide, pyriform setae in C. latisquama and of slender, piliform setae in C. sanguinea . Another striking though internal difference is that C. latisquama has the basal part of the apodemes subsumed into the body of the aedeagus (Fig. 10), which is not the case in C. sanguinea (Fig. 11).

Description:

Derm reddish brown to brown, head and rostrum darker, matte; whitish pyriform scales present but not locally clustered ( Fig. 2); rostrum slightly (males) or conspicuously longer (females) than pronotum, very slightly (female) or distinctly (male) curved throughout ( Fig. 6), lamellar process ventrad of antennal insertion not angularly projecting; antennal club slightly longer than distal four funicular segments combined; frons with appressed setae above eye; pronotum slightly wider than long, sides subparallel in basal half, roundly constricted apically and subtubulate in front; sides of aedeagus parallel, apex blunt and medially slightly produced, base of apodemes subsumed into body of aedeagus, remaining free section of apodeme shorter than body of aedeagus (Fig. 10), internal sac more than half length of apodeme and lobed, basal sclerite absent, tegmen with parameroidal lobes and basal apodeme of subequal length, male sternite 9 with distal appendices unequal; total length 3.5-5.6 mm, standard length 3.2-5.3 mm.

Distribution:

The species is known from southern Brazil and Argentina.

Plant associations:

Unknown.

Epithet:

The name is a Latin composite noun in apposition based on squama (scale) and latus (wide).
