Dasiops

Genus Dasiops View in CoL

Note 1. Dasiops species described from a holotype male with no associated female. In the genus Dasiops the male genitalia are small and often without significant species level features. In contrast the female aculeus is often characteristically shaped and is, for many species, the key factor in identification to species level. As a result, the majority of Dasiops species are described from a female holotype. A male holotype can lead to taxonomic difficulties particularly when attempting to associate conspecific females.

Note 2. Dasiops arkansensis . Described from a holotype male from Arkansas, U.S.A. Remarking on the associated allotype female from New Mexico, U.S.A. Malloch (1923b: 45) stated “the female may possibly belong to a different species, but I consider them to be conspecific at this time”

Note 3. Dasiops brevicornis . Steyskal (1980: 169) noted that this species, described from St Vincent, West Indies, may be conspecific with Dasiops inedulis Steyskal, 1980 described from Panama. However, in view of the “considerable geographic separation” between the species Steyskal, in discussion with J.F. McAlpine, considered it advisable to treat them both as distinct species until more detailed information became available. Fernandez & Couri (2016: 567) stated wrongly that the new combination (from Lonchaea to Dasiops ) is in Steyskal (1980: 169).

Note 4. Dasiops chaetiosus . Described from one holotype and one paratype female found in Arizona, U.S.A. McAlpine (1964a: 676) commented “This remarkable species seems to combine characters of Dasiops , Chaetolonchaea and Lonchaea . In general, it resembles Chaetolonchaea spp. more than anything else, but it has poststigmatal setae and a strongly setulose lunule: if it did not have poststigmatal setulae it would fit fairly comfortably with Lonchaea peregrina Becker and its allies. When the male becomes known it may be necessary to erect a new genus for it”.

Note 5. Dasiops dreisbachi . Described only from the male holotype. In the description McAlpine (1964a: 663) remarked “I am provisionally placing here a single female from Huachuca Mts., Arizona (in University of Kansas Collection). It agrees with the holotype except that it does not have hairs on the facial carina”.

Note 6. Dasiops exemptus . McAlpine (1964a: 672) stated “A female collected at the same time and place as one of the male paratypes appears to belong to this species. It has white calypters with pale yellowish white margins and fringes. I cannot see any difference between the ovipositor of this specimen and that shown for D. rugicavus ”

Note 7. Dasiops fascialis . Collin (1953: 185) identified what he thought was D. fascialis from British specimens, but Morge (1959b: 357) later recognised this as a distinct species he named D. trichosternalis .

Note 8. Dasiops luzestelae . This species name was originally proposed by Gil Hernández (2011: 75) in her Master’s thesis. As such it did not meet the criteria for publication as required by the ICZN Code. The species (as Dasiops luzestelae Korytkowski & Castro ) was subsequently re-described by Castro: 2012: 46 but once again this description was in a thesis and did not meet ICZN criteria. It was not until formally described by Korytkowski & Castro in 2013 ( Castro et al. 2013) and is now an accepted name. However, in the list of Lonchaeidae of Colombia (Fernandez & Couri 2016: 568) it is listed incorrectly as D. luzestelae Hernández, 2011 .

Note 9. Dasiops obscurus . The terminalia of the female holotype have been removed. There is a microvial on the specimen pin, but it appears that it is empty. Unless the terminalia has been cleared to such a point that it’s undetectable in the glycerol, there’s a chance it has been lost (Spencer Pote, February 2023, personal communication).

Note 10. Dasiops occultus . Described from the lectotype male, the female associated and described by Morge (1959a: 74). According to Morge (1959a: 76) the lectotype was labelled by Collin with further lectotype label added by Morge himself.

Note 11. Dasiops peruanus . According to Rohlfein & Ewald (1978: 441) the specimen in the SDEI collection is labelled as a paratype by Hennig, but they consider that it can only actually be the holotype.

Note 12. Dasiops rugicavus . Described from a male holotype, McAlpine (1960: 345) stated that “a single female from S. Rhodesia (= Zimbabwe) is provisionally assigned to this species. The complete absence of wrinkles in the frontal depression makes me uncertain about associating this female with the male from Natal. Otherwise, however, it agrees very well, the differences pointed out being quite in line with sexual differences in other species. Further collections of associated males and females from both these areas are necessary to resolve the matter”.

Note 13. Dasiops rugulosus . Fernandez & Couri (2016: 568) gave the holotype locality as Mexico, but the original description ( Norrbom & McAlpine 1997: 207) stated that the specimen was intercepted on a plane originating in Port of Spain, Trinidad. In addition, Trinidad is printed in capital letters, indicating that it is the country of origin of the holotype.

Note 14. Dasiops spatiosus . Described from the holotype male, the female associated and described by Morge (1959b: 329).
