Hispiniphis new genus

( Figs 41–92 , 101–105 )

Type species. Hispiniphis parva new species. Genus based on adult female, adult male, nymphal and larval material representing six species, of which one is newly described here, the others to be described subsequently.

Diagnosis. Adult Hispiniphis are distinguished from those of Makarovaia in having the dorsal shield less extensive anterolaterally, leaving at least setae z2, all s, and all r setae on adjacent soft cuticle, which has a thicker, micropunctate appearance distinct from the normally striate ventral soft cuticle. Adults have less strongly sclerotised and ornamented shields on the venter, including a smaller, inversely subtriangular anal shield, slightly longer than wide. Male stenitigenital shield incompletely formed, deeply excavated posteriorly, leaving setae st5 on soft cuticle or on a separated platelet medially. Hypostome of nymphs and adults short, corniculi inserted at level only slightly behind insertions of hypostomatic setae hp1. Movable cheliceral digit of female and nymphs tridentate, and with pointed process discernible on midventral face. Male chelicerae lacking a digitiform process at level where movable digit hinged to fixed digit, and with spermatodactyl projecting freely anteriorly. In addition to leg chaetotactic reductions noted for genus-group description, femur I and tibia I lacking dorsal seta ad -3; genu II lacking lateral seta al -2; genua II and III retaining ventral seta av. Tarsus I with ventrodistal acuminate process extending under pretarsus; tarsi II–IV with ventral projection under pretarsus seeming articulated, acuminate in immature instars and adults. Protonymph and to lesser extent deutonymph with opisthosoma reduced in form, size, sometimes flanked closely by posteriorly-directed legs IV.

Description. Idiosomatic dorsum. Adult female ( Fig. 42 ). Dorsal shield moderately well sclerotised, with reticulate ornamentation; shield relatively smaller in size, compared to overall dorsal surface area, not extensive enough to bear setae s1, z2, r2, r3 which remain with s4, s5, s6, r5 on surrounding soft cuticle; soft cuticle thickly striate, micropunctate, giving ornamented effect in contrast with opisthogastric soft cuticle ( Fig. 103, 104 ). Dorsal shield with a maximum complement of 13-20 pairs of setae, including seven to 12 podonotal (j1, j3–j6, z4, z5, z6, sometimes j1 off shield, sometimes j4 duplicate) and six to 11 opisthonotal pairs (J1+, J3, J4+, J5, Z2–Z5, sometimes Z2, Z3, and Z5 duplicate) ( Fig. 88 ); dorsal setae usually similar in form, somewhat variable in length, except for J5 always minute. Dorsal shield with complement of 13–15 pairs of discernible pore-like structures (three to five podonotal, 10 opisthonotal), of which five to seven pairs (two to four podonotal, three or four opisthonotal) superficially appear secretory (gland pores) and seven to nine pairs (one or two podonotal, six or seven opisthonotal) non-secretory (poroids). Soft lateral cuticle with 20–45 pairs of lateral, marginal and submarginal setae, including z2, all s, all r, sometimes Z2, and all S, R, and UR, and at least six pairs of marginal poroids, including idRp; few to many of setae on soft cuticle may be duplicate.

Adult male ( Fig. 56 ). Dorsal shield usually similar in size, ornamentation and setation to that of female; sometimes capturing one to three more pairs of setae than in female; form and relative lengths of shield setae as in female.

Idiosomatic venter. Adult female ( Fig. 45 ). Tritosternum with laciniae fused for about half of their length, without basal elaborations; laciniae nearly devoid of pilosity ( Fig. 47 ). Ventral shields variably poorly sclerotised. Presternal region smooth or faintly lineated, without platelets ( Fig. 45 ). Sternal shield fragmented, its form and setation as noted for genus-group description; sternal area with varying faint ornamentation; shield fragment sometimes with bases of setae st1, st2 circumscribed by sclerotised thickenings, while unsclerotised medial region sometimes faintly ornamented but not striated with soft cuticle. Epigynal shield lightly sclerotised, unornamented, narrow, with hyaline anterior margin hardly widened between legs III, and with posterior margin hardly widened but strongly rounded or bluntly pointed ( Fig. 48 ). Opisthosomatic venter lacking metapodal platelets, with soft striated cuticle bearing four to six pairs of opisthogastric setae (JV1, JV2, ZV2, JV5, sometimes JV3, JV4) and four pairs of poroids, flanked laterally and posteriorly by further thickened, ornate cuticle variably bearing several pairs of R - or UR - setae. Anal shield small, well sclerotised, smooth or reticulated, pyriform or inversely subtriangular, slightly longer than wide; para-anal setae inserted at mid-level of anus, shorter than postanal seta; shield with pair of gland pores gv3 on lateral edges at level of insertions of para-anal setae, and with cribrum along tapered posterior margin ( Fig. 49 ). Peritrematal shield weakly sclerotised, extending without interruption to about midlevel of coxae I; shield with gland pore gp1 located at anterior extension at level of coxa I ( Fig. 43 ); exopodal strip continuous alongside peritrematal shield only to level of coxae III, extensions between bases of coxae II–III rudimentary or absent.

Coxae I- III distal rims smooth. Leg setae generally simple, not markedly differentiated. Tarsi II and III with setae ad -1, pd - 1 as long as short pretarsus; apical ventral tarsal process acutely triangular.

Etymology. The name of the genus, feminine in gender, is a Latinised combination of the term hispidus, meaning bristly, upon which the family-group name of the beetles is based, and iphis, meaning stalwart, and a suffix commonly used among names for gamasine mites.

Distribution and habitats. The genus is currently based on one newly described species and on additional material representing five undescribed species. All instars of mites of the genus Hispiniphis are known only as subelytral symbionts of adult hispine beetles of the genus Cephaloleia , tribe Immatidiini (or Cephaloleiini ). Over 200 species of the neotropical genus Cephaloleia are recognised, including at least 40 sympatric species from lowland tropical rain forest in the La Selva Biological Station, Costa Rica, alone; larvae of the majority of species feed on unfurled leaves of various families of the Order Zingiberales ( Staines 1996, 2008, 2009, Garcia-Robledo et al. 2010), Staines & Garcia-Robledo 2014).

Remarks. Reduction in size of opisthosoma. Among species of Hispiniphis for which specimens of the nymphs are available, a smallness of the opisthosomatic region is notable ( Figs 78 , 90 ). There is a compactness of body behind the legs IV in both nymphal instars, leaving the anal shield and adjacent structures squeezed into a relatively small space. Perhaps this may be correlated with evolution towards a rapid life cycle, and lessened need for enlargement of the body region not involved in mobility. This reduction is not evident in the nymphs of the one known species of the sister-genus, Makarovaia .

Interspecific variation in adult dorsal shield attributes. The shape and ornamentation of the adult dorsal shield, as well as the complement and size of its setae, vary markedly among the five species of Hispiniphis for which we have material at hand ( Fig. 88 ). In general, the description of the genus accounts for these differences, until such time as other of these species are described subsequently. Such readily discernible morphological differences may be quite useful in determining whatever level of host specificity there may be between species of this genus of mites and their beetle hosts.

Symmetry of dorsal idiosomatic hypertrichy. Adults (to some extent preceded by nymphs) of some species of Hispiniphis display a pattern of hypertrichy that appears to be a duplicative neotrichy derived secondarily within the genus. This is indicated to a slight extent by outline of setal duplicates in Figs 42 , 45 , 56 of H. parva , but is much more evident among adults of a couple of other species, to be described subsequently. This form of neotrichy falls within the conceptual framework of cosmiotrichy, as distinguished by Grandjean (1965), in which the setae occupying a neotrichous territory are arranged in recogniseable order, usually in linear files, such that they are idiotrichous, may be assigned sigla, indicating homologies. Rarely noted as such among gamsine mites (but see Lindquist & Moraza 1999), this phenomenon will be discussed further in a subsequent paper, in which other species of Hispiniphis are to be described.
