The genus Ischnothrombium Feider,
1983 is synonymized with Whartonia Ewing, 1944.
Redescription of Whartonia diploctenum (Feider,
1983) comb.n. is given from the larvae collected in
nature. A new species, Whartonia delacruzi
sp.n. from Cuban bats is described. The new species close to W.
diploctenum and differs from the latter by larger number of
idiosomal setae (NDV=178—184 vs. 114—131), lesser lengths of setae
(AL=40—45 vs. 49—61, PL=49—57 vs. 68—86, Dmax=42—46
vs. 54—58), AM>PL vs. PL>AM, SB on level of PL bases
against SB clearly anteriad to level of PL bases, distance between SB
is as long as distance between them and PL bases (SB=31—37 vs. 28—30 in
W. diploctenum) and in shape of
scutum: posterolateral projections of scutum absent, scutum broader in
anterior part (AW=89—94 vs. 94—106), posterior scutal margin more
prominent posteriad to PL bases (P-PL=15—16 vs. 5—14), AP=32—38 vs.
40—49. Wagenaaria similis Brennan, 1967 is reported
from a new locality in Cuba; morphological data are provided.
