Three new species of chigger mites, Colicus
famulidistalis sp. n. and Eltonella
macroti sp. n. from phyllostomid bats, and
Microtrombicula guaurabensis
sp. n. from lizards, are described. Three species,
Eltonella usitata (Brenann, 1965) comb.
n., Loomisia univari (Brennan, 1965), and
Hoffmanniella beltrani (Hoffmann,
1949) are recorded for the first time in Cuba on new host species.
Colicus famulidistalis
sp. n. differs from all other species of Colicus
Brennan, 1970 in having microtarsala of leg I distad of tarsala, versus
to proximad, and by the absence of genuala III.
Microtrombicula guaurabensis sp.
n. is similar to M. phyllodactyli Webb et
Loomis, 1970 but differs from it by 4 sternal setae versus 6 (fSt = 2.2
versus 2.2.2), lesser numbers of idiosomal setae (DS = 26 versus 28, VS
= 21—23 versus 26), and much shorter PL, H, and D (18—22, 20—24, and
17—24 versus 34—38, 30, and 23—30 respectively).
Eltonella macroti
sp. n. is similar to E. usitata (Brennan,
1965) comb. n. and differs from it in having 4
posterior sternal setae versus 2 (fSt = 2.4 versus 2.2), 8 setae in 1st
posthumeral row versus 6, more numerous idiosomal setae (DS = 49—58, VS
= 74—91, NDV = 123—147 versus 40, 60, and 100 respectively), and
somewhat wider scutum (AW = 65—71 versus 60, PW = 86—94 versus 80).
E. usitata is for the
first time recorded on Phyllonycteris poeyi
Gundlach, 1860. Loomisia univari and Hoffmanniella
beltrani is for the first time recorded on Macrotus
waterhousii (Gray, 1843).
