Chlorota cincticollis Blanchard

Jameson, Mary Liz & Morón, Miguel Angel, 2001, Descriptions Of The Larvae Of Chlorota Cincticollis Blanchard And Chasmodia Collaris (Blanchard) (Scarabaeidae: Rutelinae: Rutelini) With A Key To The Larvae Of The American Genera Of Rutelini, The Coleopterists Bulletin 55 (3), pp. 385-396 : 391-392

Pupa of Chlorota cincticollis Blanchard

Figs. 17–18

Morón (1993) characterized the pupae in the tribe Rutelini as possessing 5– 6 pairs of dioneiform organs (occasionally weakly sclerotized); primary stigma (I–IV) generally darkened, stigmata V–VIII conspicuous but closed, last stigma closed, prominent or collapsed; urogomphi absent; tergo­lateral tubercles absent; tergites VII–VIII separated. The ecydsial opening of Rutelini larvae is nearly always along the entire dorsum (from head to raster) and the exuvium remains below the pupa, protecting the dorsal and lateral regions of the pupa ( Morón 1993). Pupation in the Rutelini generally occurs in a pupal cell in soil or inside rotting wood ( Morón 1993).

Specimens Studied. One pupa of C. cincticollis was collected with larvae and a teneral adult. The specimen is housed at the Instituto de Ecología (Xalapa, Mexico) with the following data: MEXICO: Oaxaca, 1.5 km de Puerto Eligio, Carr. Tuxtepec, Cerro Pelón, 1­III­ 88, 680 m, coffee plantation, P. Reyes­Castillo and C. Castillo colls., moist rotten stump with many larvae and pupae .

Description ( Figs. 17–18 ). Length 32.4 mm. Widest width 16.4 mm. Shape oval, stout, exarate. Cream­yellowish. Surface glabrous (except at apex of abdomen). Head: Bent ventrally; clypeus inflated, clypeofrontal suture clearly sinuated; labrum, mandibles, maxillae, and palps, discernible, antennal tecae expanded, rounded. Thorax: Pronotum convex, with irregular lateral borders. Mesonotum at base weakly arcuate posteriomedially. Elytral and hind wing tecae closely appressed, curved ventrally around body; elytral tecae extending to 1st abdominal segment; hind wing tecae extending to 2nd abdominal segment; legs with distinct, shortened, stout tarsomeres, meso­ and metatibial apical spurs evident. Abdomen: Segments 1–7 (ventral view) well defined; segment 8–9 coalesced, subequal to segments 5–7 combined. Segments 1–6 (dorsal view) with well defined dioneiform organs at mid­base and mid­apex between segments 1–2, 2–3, 3–4, 4–5, 5– 6; segments 8–9 coalesced; apex (except at middle) with dense, short, brown setae. Spiracles 2–4 oval and with sclerotized, piceous spiracular ring; spiracles 5–8 round, rosette­form, without sclerotized, piceous spiracular ring. Urogomphi lacking, but with latero­distal lobes well defined, with rounded apex; genital ampulla small, rounded, slightly prominent.

Remarks. The pupa of C. cincticollis is similar to that of Macraspis species , but the posterior border of the mesonotum and the tarsi are more elongated in Macraspis species.
