Type material.

LECTOTYPE, here designated, (male) labeled: on pink oval (a) “Rio”; (b) " Calymmus / cucullatus / Type Pasc"; (c) on white circle with orange border “Type”; (d) "Pascoe. / Coll. / 93 –60.”; (e) on blue paper "Tenebrionid Base / Aaron D. Smith / Catalog # 14794"; (f) on red paper, "LECTOTYPE / Calymmus / cucullatus / Pascoe / det. ADSmith 2015" (BMNH).

Note.

Specimen designated as lectotype appears to be the one figured in the original publication ( Pascoe 1871). No indication of the number of specimens in the original type series is given; however, it is possible that this was not the only individual.

Additional material examined.

Thirteen specimens. Six labeled "BRAZIL: Sta. Catarina / Nova Teutonia / [dates from Jan. 1975, Nov. 1977, and Mar. 1977] / F. Plaumann" (CASC - 3♂, 2♀, EMEC - 1♂). Five labeled "Lanca / St. Cath. Brazil / Oct. 1944" (AMNH - 1♂, 4♀). One female labeled "Cauna / S.Cath., Brazil / Dec. 1948" (AMNH). One female labeled "Rio Vermelho / S.Cath., Brazil / I. 1946" (AMNH).

Diagnosis.

Wattius cucullatus can be separated from all other known members of the genus based on the following character combination: Frontoclypeal suture strongly incised, frons shallowly depressed anterior to eyes; pronotal horn strongly produced, apex weakly bifurcated in males, prosternal process deflexed behind coxae, rarely with small projecting tubercle near apex; flight wings fully developed, meso- and metacoxae separated by more than mesocoxal width; femora lacking smooth rounded callosities; outer margins of tibia flat with two indistinct rows of callosities, apical spine absent on all tibia in males, all male femora with rounded protuberance on anterior edge of basal half.
