HOLOTYPE: adult female, with adult Cephaloleia vicina Baly on leaf of Heliconia pogognatha , February 1994, coll. EEL & ALAS; deposited in Instituto Nacional de Biodiversidad ( INBio) of Costa Rica, Santo Domingo de Heredia.

EEL; two adult females, ex Cephaloleia bella Baly on Heliconia pogognatha , 8 July 1997, coll. ALAS; one adult female, with Cephaloleia belti Baly and C. ornatrix Donckier on Heliconia pogognatha , 12 June 1997, coll.

Host identifications. Some of the identities of the host beetles and background plant substrate given above are not in accord with current molecular studies, which indicate that there is a complex of multiple cryptic species of Cephaloleia with similar morphology in the La Selva area. The following comments are based on current and ongoing analyses (Carlos Garcia-Robledo, personal communications, June 2014):

1. Cephaloleia vicina does not occur at La Selva, and specimens identified as such from there are, in all cases checked by DNA barcodes, Cephaloleia bella .

2. Cephaloleia bella normally does not occur on Heliconia pogognatha ; thousands of field diet records indicate it feeds only on Heliconia imbricata .

3. Cephalolleia belti is a broader-spectrum feeder, occuring on several species of Heliconia as well as on other, less related hosts ( Marantaceae ). The above records of Cephaloleia belti and C. ornatrix on Heliconia pogognatha are in accord with field diet records.

4. Cephaloleia belti sometimes coexists and may be confused with C. bella on H. imbricata .

Tentatively, subject to further studies, we conclude that, at La Selva, Hispiniphis parva is associated regularly with the host specialist C. bella and to some extent with the host generalist C. belti in H. imbricata , and also with C. belti in H. pogognatha .

Etymology. The specific name is from the Latin “parvus”, meaning “little”, and indicates the small size of this mite, whose adults are less than half the size (length) of those of the type-species of Makarovaia . Among material of other, as yet undescribed species of Hispiniphis at hand, females of this species are slightly the smallest ( Fig. 88 ).

Remarks. No dimorphism was discerned in deutonymphal cheliceral digits, but the possibility of its presence could not be confirmed in absence of a deutonymph with a pharate adult male.

As noted above, all instars of Hispiniphis parva are clearly associated with Cephaloleia bella , a specialist feeder in Heliconia imbricata . However, its regular association with Cephaloleia belti is less certain. Records of the latter are few, based mainly on adult mites, which may run on and off these beetles, and C. belti is a broad spectrum feeder that may sometimes coexist with specialst feeders in the same unfurled leaves of the host plants. Further comments on host specificity are presented in the following discussion.
