Phaulothrips vuilleti Hood, 1918: 147
Titanothrips portentosus Karny, 1924: 40. Synonymised by Mound, 1974: 86
Although similar in structure to fuscus, this species seems to be well characterized by the shorter, broader, tube with convex margins (Figs 27–28), and the broadly expanded pale pre-ocellar setae (Fig. 20). The head and tube of the male holotype (in USNM) measure 590 and 400 microns, with a ratio of 0.69, and these measurements of the male of portentosus (in SMNH) are 680 and 360 microns with a ratio of 0.53. In a long series of specimens from Magnetic Island, Queensland, taken from a stem gall with an abandoned wasp nest, the ratio varied from 0.65 to 0.75. Most of the specimens studied are from northern Australia, but the species has been taken from Sandgate (Brisbane), also south of Sydney, and was recorded from Tanzania by Mound & Palmer (1983).

Material examined. French Guiana: Régina (4º18’N 052º08’W); 22.xi.2007; leg. D. Lohez (INPA, 10).
Distribution. Brazil (Amazonas), French Guiana (Régina *, Roura) (Makhan 2015), Guyana (Mazaruni-Potaro District), Suriname (Sipaliwini District) and Venezuela (Amazonas, Bolivar) (Miller 2016) (Fig. 16).
Habitat. Specimens have been collected from a river margin, in a large sandy creek, in a muddy oxbow pond, in detrital pools by a forest stream, and from lights at night. The species appears to be mainly associated with margins of forest rivers (Miller 2016).

SPERM TRANSFER FORM (figs. 3, 4): Large, cone-shaped synspermia (,25 Mm) consisting of four fused spermatozoa (fig. 3);
irregular membranes located in the periphery (fig. 4 A–C). Cytoplasm in sperm conjugate heterogeneous; some dense granules and lamellae occur (fig. 4 A–C, G). Nuclei incompletely coiled and helically contorted, chromatin irregularly condensed (fig. 4D, E). Axonemes hardly visible (fig. 4F) due a low electron density compared to the nonhomogeneous cytoplasm. A thin (, 80 nm) secretion sheath, developed in the deferent ducts, surrounds each sperm conjugate (fig. 4G).
SPERMATOZOA (fig. 4): Acrosomal complex: AV cylindrical and small (,4.9 Mm); narrow subacrosomal space for the most part, slightly widening posteriorly (fig. 4E, 4E inset). AF thin, originates from narrow subacrosomal space in anterior AV and extends into a nuclear canal, but clearly ends before axonemal base. Nucleus: prcN elongated (,66.8 Mm) (fig. 4 A–C), helically contorted, and with a conspicuous, irregular chromatin-condensation pattern. The small implantation fossa contains only centrioles (fig. 4G); peN absent. NC empty for the most part in mid and late spermatids and no longer visible in mature sperm. Axoneme: 9+3 microtubular pattern.
NOTES ON SPERMIOGENESIS (fig. 5): Within the testis all stages of spermiogenesis are present. Germ cells of the same developmental stage in conjunction within cyst. The acrosomal vacuole of early spermatids irregularly electron dense, resulting in spotted appearance (fig. 5A). It is separated from the anterior pole of the nucleus by a small electron-dense plate. The two centrioles migrate toward posterior pole, where they arrange in a tandem position (fig. 5B). Chromatin starts to condense only in a small portion near the nuclear canal that contains the acrosomal filament (fig. 5C, D) while the so-called manchette of microtubules (i.e., a ring or ruffle of microtubules) surrounds the entire nuclear material (fig. 5C, D). Further development includes elongation of the nucleus. The chromatin condenses irregularly and appears “folded” (fig. 5E) with a typical “looped” appearance in cross section (fig. 5E, H). Although the axoneme has the typical 9+3 microtubular pattern (fig. 5F), the central tubuli are very short, thus the main part of the axoneme shows 9+0 microtubular pattern (fig. 5G). While spermatids start to fuse at the end of spermiogenesis, the manchette of microtubules disintegrates (fig. 5H).

SPERM TRANSFER FORM (fig. 11): Ovalshaped synspermia (,10 Mm), comprising four sperm (fig. 11A). In the periphery of the sperm conjugate, numerous membranes are visible (fig. 11B, arrow). Synspermia surrounded by a thin (, 80 nm) secretion sheath (fig. 11B, C); cytoplasm electron dense within sperm conjugates of the ejaculatory duct (fig. 11D), some mitochondria present.
SPERMATOZOA (fig. 11): Acrosomal complex: AV conical with wide subacrosomal space (figs. 11A, C), proximally sunken into the anterior pole of prcN (fig. 11C). AF originates from subacrosomal space, extends into NC, but clearly ends before axonemal base. Nucleus: prcN deeply indented at its anterior pole (bowl shaped), irregularly shaped with irregularly condensed chromatin (fig. 11A, B). peN short, flattened, (fig. 11D). NC peripheral (fig. 11 A–C). Axoneme: proximal centriole longer than distal centriole, 9+3 microtubular pattern.
Note on Spermiogenesis (fig. 12): All stages of spermiogenesis present in the testis. Spermatids of the same developmental stage arranged in cysts. Early spermatids characterized by a large, oval nucleus surrounded by a manchette of microtubules and small AV (fig. 12A inset) that is separated from the nucleus by a distinct electron-dense border (fig. 12A). The AF originates from the subacrosomal space (12C). The chromatin begins condensing in the center of the nucleus and appears fibrillar (fig. 12A, B). The small implantation fossa is irregularly shaped in early spermatids (fig. 12B, B inset). There is always a small amount of electron-dense, granular material associated with the proximal centriole (fig. 12D). A collar of electron-dense, platelike secretions surrounds the base of the Ax (fig. 12E). At the end of spermiogenesis late spermatids that remained connected via cellular bridges start to fuse, finally resulting in synspermia.

SPERM TRANSFER FORM (fig. 9): Very large (.30 Mm), cone-shaped synspermia that presumably comprise four sperm, which are loosely arranged (fig. 9A, B). In the periphery of the sperm conjugate irregular tubelike membranes, originating from membrane invaginations, are visible (fig. 9C). The cytoplasm is heterogeneous, numerous electron-dense droplets and lamellae are visible (fig. 9B, C). The nuclei are elongated, cross sections reveal helical contortion, indicated by curls of the nuclei (fig. 9B). Numerous mitochondria are present. A thin, homogeneous secretion sheath (, 80 nm) surrounds the sperm conjugates (fig. 9A, C). The chromatin of mature spermatozoa is irregularly condensed (fig. 9D).
SPERMATOZOA (figs. 9): Acrosomal complex: AV cylindrical; narrow subacrosomal space, (fig. 9C). AF originates from the subacrosomal space, extends into NC. Nucleus: prcN elongated (fig. 9A, B), with conspicuous chromatin-condensation pattern (fig. 9A, D). Implantation fossa very small and contains only centrioles. peN not identifiable. NC located in the periphery, empty for the most part. Axoneme: short, indicated by only few cross sections that are visible in the sperm conjugate (fig. 9B); 9+3 axonemal pattern (fig. 9B).
NOTES ON SPERMIOGENESIS (fig. 10): The small developing acrosomal vacuole with a narrow subacrosomal space (fig. 10A inset) separated from the nucleus by a distinct electron-dense plate (fig. 10A). At the posterior pole of the nucleus both centrioles migrate toward the latter, initiating the formation of a small implantation fossa (fig. 10B). The nucleus elongates markedly while the chromatin condenses irregularly, resembling an electron-dense thread in midspermatids (fig. 10C). Mature spermatozoa remain the irregularly condensed chromatincondensation pattern (fig. 10D, E). At the end of spermiogenesis four spermatids fuse (fig. 10E) to form a very large sperm conjugate. The manchette of microtubules disintegrates during further sperm conjugate differentiation.
