TYPES: Male holotype and female allotype from Antananarivo province, Tsimbazaza, 18.93036 ° S, 47.52693 ° E, general collecting, 13 October 1947, Paulian (MRAC PBI_OON 00035121).
ETYMOLOGY: The species epithet is a name in apposition taken from the type locality.
DIAGNOSIS: Males of O. tsimbazaza can be most easily distinguished from those of other Opopaea species by a cymbiobulbus with a round anterior margin, which has a very thin and compact tip directed downward and bearing above it a round hole on prolateral side (figs. 832, 833, 836, 837, 840, 842, 844). Females of O. tsimbazaza can easily be recognized by a very short and narrow postgynum depression and a scutal ridge that together form an inverted triangle; the postgynum depression is sclerotized but abruptly interrupted medially, and the scutal ridge bears above its median surface a very distinct round parmula (figs. 818, 838, 839).
DESCRIPTION: Male (holotype) (PBI_OON 35121). Medium-sized species. Total length 1.59. Color: orange to yellowish orange. Carapace: pars cephalica not elevated with one row of two widely separated sets of two denticles bearing long thick hairs (figs. 829, 830), carapace anteriorly narrowed to less than one third maximum width. Carapace anterolateral corners without sclerotized triangular extension. Clypeus very low, not rebordered. Chilum absent. Eyes large. ALE largest. ALE and PME oval, PLE circular; PME darkened compared to other eyes, posterior eye row straight viewed from above, procurved from front; ALE separat- ed by less than their radius, ALE-PLE separated by less than ALE radius, PME touching throughout most of their length, PLE-PME separated by less than PME radius. Sternum longer than wide with radial furrows between coxae, surface hairy, without pits, shape of posterior part between coxae IV wide, hexagonal, not constricted. Lateral margins of area between coxae III unmodified, without posterior lumps; setae sparse, dark, needlelike, evenly distributed, originating from surface, without hair tufts (figs. 828–831). Palp posterior margin straight and with one smooth proximal protuberance. Palpal femora half the size of palpal patella and inserted in the middle of the patella. Palpal fenestra large and enlarged anteriorly, very close to palp tip, fenestral anterior top slightly elevated (figs. 816, 817, 832,
833, 836, 837, 840–847).
Female (allotype) (PBI_OON 35121). Total length 1.71. Abdomen round, not flattened with ventral scutum squared at posterior end (figs. 819–821). Epigynum scutal ridge thin, weakly sclerotized except medially (figs. 818, 838, 839).
