Type host.

Passer domesticus (Linnaeus, 1758) ( Passeridae ).

Type locality.

Unknown (most likely Netherlands).

Differential diagnosis.

In both sexes showing the characteristics of the " M. serini -Artengruppe" ( Klockenhoff 1984b), or Myrsidea serini species-group ( Price and Dalgleish 2007). It is well characterized with 1) weakly developed hypopharyngeal sclerites; 2) abdominal segments with continous row of tergal setae across segments I-II, and with well-defined median gap in row of tergal setae on other segments; 3) the females with non enlarged and unmodified tergites (except tergites II-III with slight medioposterior curvature) (Figs 1-3 ); 4) the females with a strongly spiculate posterior margin of the subgenital plate; and 5) the males with characteristic genital sac sclerites (Figs 4-18 ).

Description.

The following overall description is based on a large number of specimens from different hosts. Data for the most important morphometric characteristics for specimens according to their hosts are presented in supplement Tables S3b-S12. For better orientation and to avoid repetition of lists of hosts in the following text we refer to Myrsidea from particular hosts under their previous names in quotation marks, for example, " M. serini ", " M. textoris ", etc. (for specification see Table S1).

To evaluate the status of " M. argentina " we also examined available nymphs of 3rd instar: 1) two nymphs from Spinus magellanicus - type host of " M. argentina ", and 2) one nymph from Passer montanus - host of M. quadrifasciata . These nymphs differ from previous descriptions of " M. argentina " by Kellogg (1906) and " M. serini " by Cicchino and Valim (2015). Here the essential characters are given, with data from Kellogg (1906) and Cicchino and Valim (2015) in parentheses as (Kellogg/Cicchino and Valim).

Remarks.

Piaget (1880) gave only a short description of M. quadrifasciata based on 13 females and 11 males from Passer domesticus . Later Thompson (1937) in his review of Piaget’s collection referred to the presence of only one slide with two females of M. quadrifasciata , but mentioned Passer montanus as host. He also stated: "A male is mentioned in the original description, but there is no male in the collection." Subsequently Clay (1949b) specified that there is no original Piaget’s specimen of M. quadrifasciata from the type host, either in the NHML or in the museum in Leiden and confirmed the presence of two females from Passer montanus in the NHML.

We were able to examine slide no. 840 mentioned by Thompson (1937) and Clay (1949b), labeled as Menopon fasciatum , that is deposited in NHML and originally from Piaget’s collection. Moreover, there were also three slides labeled as " Myrsidea 4fasciata " from Passer domesticus in the collections of NHML; but in fact, there is actually only one slide (No. B.M.1955-616) with one male (here designated as neotype) belonging to this species. On the next two slides (both under the same number, B.M.1980-40) there are two females of Menacanthus eurysternus (Burmeister, 1838) collected from the same locality as Myrsidea , i. e. England: Cheshire, Great Budworth and Plumbey by A.W. Boyd (10.ix.1932), and J.S. Booth (8.10.1932), respectively. It is probably the same situation concerning the record of Menacanthus quadrifasciatum Piag. from house sparrow (collected by A.W. Boyd (13.3.1923) in Great Budworth) reported by Britten (1932). The name of this species is manually rewritten as Menacanthus spinosus Piaget, 1880 (now M. eurysternus ) in the available copy of this paper on phthiraptera.info web page (http://phthiraptera.info/sites/phthiraptera.info/files/44361.pdf).

There are few reports about the occurrence of M. quadrifasciata on P. domesticus and P. montanus (see Table 1 ). It is quite prevalent in Asia with prevalence 20-50% and mean intensity only about 2 specimens per infested bird (Table 1 ).
