Genus: Conocassis
Name
Conocassis invaginata Caterino & Tishechkin, 2014 sp. n. – Wikispecies link – ZooBank link – Pensoft Profile
Type locality
BRAZIL: Pará, Carajas [6.06°S, 50.2°W].
Type material
Holotype female: “Octobre 1984, piége d’interception CARAJAS, PARÁ, N. DEGALLIER” / “Caterino/Tishechkin Exosternini Voucher EXO-00008” (UFPR). Paratype female: BRAZIL: Pará, Carajas, S. Norte, xi.1984, N. Degallier (CHND).
Diagnostic description
Length: 1.9 mm, width: 1.4 mm; as for generic description, with the following specific characters: body rufobrunneus; frontal stria extending to near apex of epistoma; side of pronotal process with two distinct creases, the lowermost deeply invaginated, more broadly open, the second, more dorsal crease also rather deeply invaginated; pronotal disk with carina extending anterad from basolateral corner toward median invagination; pronotal process abruptly rounded to apex only from middle in lateral profile; pronotal disk very finely alutaceous behind median process; median elytral interval strongly depressed in basal half, the 4th dorsal stria strongly elevated and displaced laterad, texture of median interval finely granular throughout; fragments of 5th dorsal stria present in median interval; texture of outer intervals finely granulate throughout, not smoother apically; epipleural margin granulate but not strigose; presternal suture impressed across middle; abdominal ventrites 2-4 with sparse, oblique strigae at sides; propygidium strongly convex, about as long as pygidium along midline; propygidial punctures very elongate, coarse and deep, especially at sides, alutaceous within; pygidium strigose in basolateral corners, becoming simply, finely punctate apicomedially.
Remarks
As noted under the preceding two species, this species is best recognized by the presence of only two lateral creases on the pronotal process (Fig. 2C), both of which are deeply invaginated. The completely granulate elytral intervals and presence of fragments of the 5th dorsal stria (Fig. 1D) are also unique.
Etymology
This species is named for the fact that it has the deepest pronotal invaginations in the genus.
