Orchestina dentifera Simon, 1893a: 248 View in CoL (one male, four females, and one juvenile syntypes from Sri Lanka (ex Ceylan), Kandy!, date not provided, M.E. Simon, deposited in MNHN 6025 (additional number 15250), PBI_OON 50024; examined) – Simon, 1893d: 294 – Dalmas, 1916: 232, figs. 21, 27.

Orchestina justini Saaristo, 2001: 356 View in CoL , figs. 190– 195 (male holotype from Seychelles: Silhouette , Anse Cimitiare, under Casuarina View in CoL bark, Jan.17, 1999, M. Saaristo leg., deposited in MZUT 1250, PBI_OON 50030; same data, 3 male and 3 female paratypes, from old stems of Ipomea hanging down from stones, Jan. 18, 1999, M. Saaristo leg., deposited in MZUT 1251 (partim), PBI_OON 50029; all examined). NEW SYNONYMY.

SYNONYMY: The species was first described by Simon (1893a) and later redescribed by Dalmas (1916); both authors noted the conical projections on the chelicerae, which is the most conspicuous characteristic of males, although illustrations were provided only by Dalmas. Later Saaristo (2001) described a new species from the Seychelles without any comparison or mention to the one previously described by Simon. We have examined only one vial from the MNHN with no details about the type status of the specimens. The locality is the same for those specimens described by Simon, so it is quite possible that this vial contains the syntypes because, as far as we know, it is the only vial available from that museum. We have compared the American specimens (figs. 25, 27) with the type material described by Saaristo and the material from the MNHN (fig. 26) and did not find any significant differences. The species is amply distributed in tropical areas throughout the world, so it is not surprising that it occurs in the Seychelles and Sri Lanka.

The material from the MNHN is in good condition although for detailed descriptions we have used material from Brazil.

MALE (PBI_OON 42164): Total length 1.00. Habitus as in figures 25A, C, 26A. CEPHALO- THORAX: Clypeus margin unmodified, curved downward in front view, vertical in lateral view, high, ALE separated from edge of carapace by their radius or more, setae dark, needlelike. Sternum as long as wide, pale orange, anterior margin unmodified, coloration as carapace (fig. 26C). Chelicerae, endites, labium pale orange. Chelicerae anterior face with strong, conical pro- jections on median line (figs. 25G, 26B, 27A, E), promargin with three long, near parallel setae (fig. 27A, C), fang unmodified (fig. 27F). Labium elongated hexagon, same as sternum in sclerotization; with six or more needlelike setae on anterior margin, median region with two pairs of flattened setae (fig. 27B). Endites without serrula, anteromedian tip unmodified, anterior dorsal region excavated (fig. 27D). ABDOMEN: Ovoid, dorsum soft portions white, with gray netlike pattern. LEGS: Yellow; spination, metatarsi: IV d0-0-1; p0-0-1; r0-0-1. GENITALIA: Proximal segments yellow, femur sinuous; patella attached to tibia subbasally, cymbium yellow, ovoid in dorsal view; bulb pale orange, more than 2× as long as cymbium, stout, spherical; embolus short, dark; sperm duct not highly coiled, with only one loop (figs. 36D–F, 43).

FEMALE (PBI_OON 42163): Total length 1.00. Habitus as in figures 25B, D, 26D. CEPHALO-

THORAX: Carapace yellow (fig. 25E). Clypeus slightly sloping forward. PLE-PME separated by less than PME radius. Chelicerae anterior face unmodified, promargin with needlelike setae. Endites with serrula in single row. LEGS: Spination, metatarsi: IV d0-0-1; p0-0-1; r0-0-1. GENI-

TALIA: Epigastric region with highly convex ridge (fig. 44C); external and internal pockets absent; anterior receptaculum with wide, rounded base, bifid tip; posterior receptaculum present, posterior apodeme bar shaped (figs. 41A, 44C).

DISTRIBUTION: Besides the type locality, also known from Haiti, Jamaica, Brazil, and Seychelles ( maps 5 and 24 View MAP 5 ). The species has been also collected in other regions of the world such as Isla Reunion (Indian Ocean) and Tanzania (A. Henrard, personal commun.).
