Question: How many species does this genus, after which Disk Usage Analyzer was originally named, have?

Context paragraphs:
Otiorhynchus: Otiorhynchus (often spelt "Otiorrhynchus") is a large genus of weevils in the family Curculionidae.  Many species of the genus, particularly the black vine weevil ("O. sulcatus") and the strawberry root weevil ("O. ovatus"), are important pests, both as larvae and as adults.  Larvae feed on plant roots.  Adults are flightless with fused elytra and feed at night on plant foliage.  In many species of the genus at least some races are polyploid and parthenogenetic, while the rest of the races and species are diploid and bisexual.  "Otiorhynchus" weevils, particularly "O. scaber", have been a popular subject for studies of the evolution of parthenogenesis.  The genus is native to the Palearctic region.  However, sixteen species were inadvertently introduced to North America and have become widespread there.

Adansonia: Baobab is the common name for each of the nine species of tree in the genus Adansonia.  The generic name honours Michel Adanson, the French naturalist and explorer who described "Adansonia digitata".

Filelight: Filelight is a KDE graphical disk usage analyzer, part of the KDE Utils package, which uses the sunburst chart technique to display disk usage.  Instead of showing a tree view of the files within a partition or directory, or even a columns-represent-directories view like "xdiskusage", it shows a series of concentric pie charts representing the various directories within the requested partition or directory and the amount of space they use (this method being known as a sunburst chart, ring chart, or multilevel pie chart).  A user may also click on the pie chart segment representing a particular directory, and repeat the analysis for that directory, right click that segment to open a file manager or terminal emulator in that location, or copy to clipboard or delete the directory, and they may right click the segment representing a file to open it, copy it to the clipboard, or delete it.

Drosophila: Drosophila ( ) is a genus of flies, belonging to the family Drosophilidae, whose members are often called "small fruit flies" or (less frequently) pomace flies, vinegar flies, or wine flies, a reference to the characteristic of many species to linger around overripe or rotting fruit.  They should not be confused with the Tephritidae, a related family, which are also called fruit flies (sometimes referred to as "true fruit flies"); tephritids feed primarily on unripe or ripe fruit, with many species being regarded as destructive agricultural pests, especially the Mediterranean fruit fly.  One species of "Drosophila" in particular, "D. melanogaster", has been heavily used in research in genetics and is a common model organism in developmental biology.  The terms "fruit fly" and ""Drosophila"" are often used synonymously with "D. melanogaster" in modern biological literature.  The entire genus, however, contains more than 1,500 species and is very diverse in appearance, behavior, and breeding habitat.

WinDirStat: WinDirStat is a free and open-source graphical disk usage analyzer for Microsoft Windows.  It is notable for presenting a sub-tree view with disk use percentage alongside a usage-sorted list of file extensions that is interactively integrated with a colorful graphical display (a treemap).  Created as an open source project released under the GNU GPL, it was developed using Visual C++/MFC 7.0 and distributed using Sourceforge.  The project was inspired by KDirStat, a KDE application for Unix-like operating systems.

Disk Usage Analyzer: Disk Usage Analyzer is a graphical disk usage analyzer for GNOME.  It was part of gnome-utils, but was split off for GNOME 3.4.  It was originally named Baobab after the "Adansonia" tree.  The software gives the user a menu-driven, graphical representation of what is on a disk drive.  The interface allows for selection of specific parts of filesystem being scanned so a single folder, the entire filesystem, and even remote folders and filesystems can be scanned.  The graphical representation can be switched between a ring chart and a treemap chart so the presentation can be tailored to the specific content being scanned.

Xylogics: Xylogics or Xylogic Systems was started in 1970 by three former NASA employees.  The company was originally named Xynetic Systems, but this name was already in use by a California company, so the group in Needham, MA changed their name in late 1970 to Xylogic Systems.  Their original business was the design and development of computerized newspaper typesetting and editing systems.  The first system was developed for the Daytona Beach News Journal, with the Farmington, NM newspaper getting the second system.  By 1972, Xylogics had grown to more than 15 people, and moved to Natick, MA.  The company used the GRI mini-computer, and custom designed many circuit boards to support disk drives, paper tape punches and readers, and automatic capture of newswire service feeds.  By 1974, the company had developed a CRT editing station, and offered systems of up to 4 computers and more than 50 terminals for newspaper or in-plant publishing to perform editing and typesetting.  About this time, a second division was created to design and build disk controllers for DEC computers, derived in part from the successful designs and manufacturing capability developed for the newspaper business.  In 1976, a major customer of Xylogics, Dymo Graphics Systems, purchased the newspaper product line and hired most of the original developers.  Dymo Graphics, of Wilmington, MA was the first company to develop laser technology for typesetting applications.  Dymo Graphic Systems combined their typesetting equipment business with the Xylogics editing systems, and by 1978 had over 100 turnkey typesetting systems in use worldwide.  The Xylogic Systems typesetting capability was the first with WYSIWYG (What You See Is What You Get) printing capability for Tabloid size page layout, and later full page layout.  Capability included on-line classified ad capture with automated pricing, in addition to full page markup and typesetting.  In 1977, Dymo was purchased by Eselte Corporation, who wanted control of the highly successful "Dymo Label Maker" consumer product.Eselte sold the newspaper and typesetting business to ITEK corporation in 1978, who wanted the laser technology IP (Intellectual Property).  ITEK declined support to the newspaper and typesetting business, and in 1979, the newspaper product development and manufacturing staff of 150 engineers, technicians, assemblers, and field support personnel had dwindled to 2 by January, 1980.

Caulanthus: Caulanthus is a genus of plants in the mustard family.  Plants of this genus may be known as jewelflowers.  They are also often referred to as wild cabbage, although this common name usually refers to wild variants of "Brassica oleraceae", the cabbage plant.  Jewelflowers are native to the southwestern United States and northern Mexico, where they are often found in warm, arid regions.  Many species have an enlarged, erect stem rising from a basal rosette of leaves.  Flowers arise directly from the surface of the stem; many species have colorful, bell-shaped flowers.  The best-known of the fourteen species is probably the desert candle.

Wireshark: Wireshark is a free and open source packet analyzer.  It is used for network troubleshooting, analysis, software and communications protocol development, and education.  Originally named Ethereal, the project was renamed Wireshark in May 2006 due to trademark issues.

Nothobranchius: Nothobranchius is a genus of small, freshwater annual fish.  It has been alternatively classified in the family Nothobranchiidae or a more inclusive Aplocheilidae The species are mainly found in East Africa from Sudan to northern South Africa, but half a dozen species are found in the upper Congo River Basin and two species ("N. rubroreticulatus" and "N. thierryi") are from west-central Africa.  The greatest species richness is in Tanzania.  Many species have very small distributions.  There are many species: as of 2016 there are more than 70 species.
