All specimens are deposited in the Entomological Collection of Instituto de Ecología, A.C. (IEXA- INECOL), Veracruz, Mexico . Adult diagnosis. Palp segment 5 longer than 0.5 the length of palp segment 3, and longer than 3+4; antenna with simple ascoids. Male with gonocoxite + gonostylus slightly longer than lateral lobe; gonocoxite with basal tuft of setae more or less arranged in an oblique line; gonostylus with 2 spiniform setae, one setiform at base and one preapical setae, the median spiniform setae inserted in distal 0.33; lateral lobe length about five times its maximal width; paramere simple, capitate, with conspicuous group of setae at apex. Female with cibarium with 4 horizontal teeth, vertical teeth disposed in 1+1 diagonal lateral groups; spermatheca globular, striated, the apical annulus the longest; spermathecal common and lateral ducts wide, the common nearly as wide as spermatheca and no longer than twice its own width ( Ibáñez-Bernal, 2001 ). Comments. Dampfomyia beltrani is morphologically similar to Da. disneyi ( Williams 1987 ) and Da. steatopyga ( Fairchild and Hertig 1958 ) , but the male Da. steatopyga can be separated because it has the median spiniform seta of the gonostylus inserted at middle and the lateral lobe widther (0.4 times as long as wide), and from Da. disneyi because this species has the lateral lobe 0.4 times as long as wide, whereas in Da. beltrani the lateral lobe is more narrow, with about 0.6 times as long as its maximum width. It is important to highlight the fact that figures 102A and 102C in Young & Duncan (1994) are wrongly labeled, as Fig. 102 A actually corresponds to Da. disneyi and Fig. 102 C to Da. beltrani . Females of these three species are indistinguishable with the characters traditionally used. However, there seems to be some differences in the length proportions of flagellomere 1 as compared with the labrum, nonetheless this possible difference needs to be confirmed statistically. Pupa description. Length without larval exuvia 2.94 ± 0.25 mm (n=9). Females longer ( 3.09 mm , n=5) than males ( 2.89 mm , n=3) ( Figs. 1–29 ). Head with antennal sheath showing outlines of all flagellomeres of the imago; post-ocular lobe lateral situated, cone-shaped and without divisions. Mouthparts sheath smooth; clypeal sheath slightly prominent; head chaetotaxy as presented in Table 5 ( Figs. 2 , 6, 7 ). Thorax with 11 pairs of setae; prothorax with 3 setae ascendant disposed in relation to the ventilatory orifice; mesothorax with five setae, of which two are chaetic prealars, comparatively large (lenght 0.15 ± 0.001 mm ) and stout, originated on tubercles (t. pr-a) ( Figs. 8, 10 , 16 ) and mesonotal tubercle with continuous border ( Figs. 15 , 18 ); metathorax with five sensilla, of which three are basiconic, and two are styloconic, all of which are implanted on a tubercle near the base of halters ( Figs. 8 , 22 ); thorax chaetotaxy in Table 5 . Abdomen with nine visible segments, the width of every segment is twice its own length, and they diminish regularly in size towards the caudal region ( Figs. 1 , 9, 11 ). Abdominal segment I: Tergum with four pairs of sensilla, pleura and sternum covered with the thoracic appendage sheaths. Abdominal segments II–III: each tergum with 5 pairs of sensilla similar in form and location; pleura and sterna II–III covered by the thoracic appendage sheaths ( Figs. 1 , 9 , 24 ). Abdominal segments IV–VII: each tergum with 5 sensilla similarly distributed as previous segments; each sternum with 4 sensillae ( Fig. 9 ). Abdominal segment VIII: covered by larval exuvia, male and female both with three pairs of very small basiconic sensilla ( Fig. 11 ). Abdominal segment IX: covered by the larval exuvia, but when retired, sexual morphological differences can be observed: in males there are two lobes at each side, one simple covering the lateral lobe and the other divided containing the gonostylus and gonocoxite, and in females two simple and short lobes at each side, one covering the oviscape and the other the cercus; without setae ( Figs. 3 , 11 ).

In one pupal specimen, a mesothoracic sixth sensilla (supernumerary) lateral to setae 2T was observed; however, it will be necessary to study more specimens of other species to determine if it could have taxonomic value. Additionally, setae alveoli were observed between prothoracic 2P and 3P, near mesothoracic 1M, and near metathoracic 3T, that could be placoid sensilla (superficial sensorial organs of Forattini). Abonnenc (1956) made the same observations, and included them in his numerical system as seta 3, but leaving out those of the metathorax. In Da. beltrani , these alveoli or placoid sensilla were observed near sensilla 2 in all abdominal segments. FIGURES 1–3. Pupa of Da. beltrani ; 1. Lateral view; 2.

Previous chaetotaxy systems do not consider some characteristics observed in Dampfomyia beltrani . In this species, there is only one sensilla on I–VII pleura (5—I–VII), in constrast of the two observed in other species, and abdominal sterna I–III have no setae, whereas sterna IV–VII have 4 sensilla instead of three ( Forattini, 1973 ) or two ( Barretto (1941) seen in other species. Finally, in Da. beltrani segment VIII has three sensillae and one alveolus near sensilla 1—VIII , but it could be placoid sensilla. Abonnenc (1956) mentioned four setae in segment VIII, whereas Forattini (1973) did not refer to them. Fourth instar larva description. Body length (excluding caudal setae) 4.05 ± 0.53 mm ; head length 0.45 ± 0.02 mm ; maximal width 0.35 ± 0.02 mm ; antenna length 0.12 ± 0.01 mm , (n= 9) ( Figs. 30–57 ).

Abdominal chaetotaxy in Table 8. Third instar larva description. (Figs. 58–75) Similar to fourth instar except for the following characteristics: Body length (excluding caudal setae) 2.28 ± 0.25 mm ; head length 0.33 ± 0.05 mm ; head width 0.26 ± 0.03 mm ; antenna length 0.07 ± 0.02 mm (n=3).

( Figs. 87–98 ) Similar to previous described larva instars except for the following characteristics: Body length (excluding caudal setae) 1.07 ± 0.23 mm ; head length 0.17 ± 0.01 mm ; width 0.14 ± 0.00 mm; antenna length 0.05 ± 0.01 mm (n=5). Thorax and abdomen whitish, head when emerged grey, later pale brown. Antennal segment I length about 0.43 as long as segment II; segment II digitiform, apical sensilla as described for other instars ( Fig. 89 ); genal posterior area with spaced spicles irregularly disposed but postmentum bare ( Figs. 87, 88 ). Head chaetotaxy in Table 7 . Anterior prothorax with six setae, posterior prothorax with nine setae (Table 8) disposed as in Figure 93 and 94 . Ventilatory orifices not observed. Meso and metathorax each with 11 setae (Table 8, Figs. 93–94 ). Abdominal segment VIII with 8 setae (Table 8) disposed as in Figures 93 and 94 . Comments. Spicule distribution on the genal posterior region, a pattern which is only apparent in the fourth instar, likely has no taxonomic importance for distinguish this species because imbricated arrangement was documented by Hanson (1968) in eleven other species, some of which are also distributed in Mexico , as is the case of Psathyromyia shannoni (Dyar) , Pintomyia ovallesi (Ortiz) , Mi. trinidadensis (Newstead) , Trichopygomyia triramula (Fairchild & Hertig) , and Pintomyia serrana (Damasceno & Arouck) . According to the morphological classification of the antenna of Leite & Williams (1996) , Da. beltrani corresponds to category III for Neotropical larvae, in which Lu. gomezi (Nitzulescu) , and Da. vespertilionis (= Lu.vespertilionis ) (Fairchild & Hertig) are included ( Hanson, 1968 ). Larval instars of Da. beltrani show differences in the number of setae and sometimes in the shape, especially between first and second instars. In general, thoracic and abdominal dorsal internal and intermediate setae are smallest as compared with the dorsal external setae, a characteristic that allows distinguishing the genus Brumptomyia (tribe Brumptomyiini) from the other known American Phlebotomiini ( Mangabeira, 1942 ; Hanson, 1968 ). Ventral abdominal I–VII setae are constant in all instars (Table 8) as well as the ventral thoracic setae, but in Da. beltrani we found a previously unmentioned seta, named as internal ventral accessory seta b, which is in front of the ventral internal seta.

The first instar larva can easely be recognized by the presence of the oviruptor and the inapparent ventilator orifices (probably a metapneustic condition). There are also other differences: anterior prothorax without dorsal (dorsal internal and intermediate setae), meso and metathorax with one accessory seta associated to the ventral external and latero-ventral setae (5 and 11 respectively), and the lateral setae (4) (as the other instars have two accessory setae (a and b) and a laterobasal seta at base of seta 4); abdominal segments I–VII without latero-ventral accessory setae b, the lateral seta (5) has the same length than lateral seta (4), the dorsal internal seta 1 is as long as dorsal intermediate seta (2); and caudal lobe of the abdominal segment IX with the internal seta as long as 0.28 the length of the external. There are differences between second and third larval instars, especially related to thoracic chaetotaxy. Second instar has the prothorax dorsal intermediate seta 2 spiniform, whereas in third instar it is espiculate; in second instar larva the prothorax ventral anterior external seta 5 is spiniform, whereas in third instar larva is barbed; second instar larva has the prothorax latero-ventral seta 11 similar in length than ventral antero-external seta 5, but in the third instar larva it is 2.25X the length of ventral antero-external seta; in the second instar larva meso and metathorax lateral seta 4 is represented by three spiniform setae (accessory superior a, inferior b, and lateral-basal 5) which in the third instar larva change to only two, one barbed and one speculate; finally in the second instar larva the accessory lateral seta b of abdominal segments I–VIII is spiniform, whereas in third instar larva it is barbed.

Third and fourth instar larvae are morphological and chaetotaxical similar, distinguished only by the size of the head capsule, and the presence of the dorsal pigment patch on abdominal segment VIII of fourth instar larva. The form and extent of this pigmented area apparently varies according to species (Barretto, 1943). Hanson (1968) described the fourth instar larvae of Da. vespertilionis and Da. isovespertilionis , two species that are included in Dampfomyia (Coromyia) . This author found that larvae were difficult to distinguish morphologically as it is the case with the adults, but he considered that the relative length of dorsal setae could be the principal difference to distinguish them. Hanson’s descriptions of Da. vespertilionis and Da. isovespertilionis show morphological and chaeotoxical similarities with Da. beltrani . Nevertheless, those species difer from Da. beltrani by setae 1C and 3C simple and 2C and 5C barbed, anterior prothoracic seta 5 barbed, posterior prothoracic seta 11 basiconic spiniform, meso and metathoracic setae 4 and 5 with one accessory seta, abdominal segments without accessory seta a, and seta 7 absent in the segment VIII. Egg description. ( Figs. 99–113 ) Elipsoidal, length 0.60 ± 0.05 mm ; maximal width 0.14 ± 0.02 mm . Median region with a pattern of simple parallel and longitudinal ridges, the last ones poorly connected; parallel ridges with small lateral projections that do not have contact with longitudinal ridges ( Figs. 99–109 ); ridges high 1.77 ± 0.38 Μm; polar areas with ridges which are poorly connected by perpendicular projections gaving a reticulate apperiance ( Figs. 102, 103 , 104–108 ); basal coat rugose; vegetative pole with one micropyle, its diameter about 1.27 ± 0.17 Μm, surrounded by small spaciated tubercles ( Figs. 110–113 ). Comments. Exochorionic pattern of Da. beltrani seen at 330X allows considering in the category of eggs with parallel non-connected ridges. Nevertheless, when seen at 1200–2200X, ridges show weak lateral projections; poles and some parts of the egg median region have lateral projections of ridges weakely connecting in an irregular form, giving the appearance of reticular pattern. Of Galati’s genus Dampfomyia Addis, Da. anthophora (Addis) and now Da. beltrani are the only two species whose egg exochorionic pattern has been described. In spite the fact that the exochorionic pattern of Da. anthophora has been considered of connected ridges type , its topography is reticular formed by longitudinal and parallel ridges weakly connected with slight connections at irregular intervals ( Endris et al., 1987 ). Following Pérez & Ogozuku (1997) , phlebotomine sandfly eggs usually has two micropyles (they call it aeropyle), but some species only have one ( e. g ., Migonemyia migonei França , Evandromyia evandroi Costa Lima and Antunes, Lu. renei Martins , Falcão and Silva). Adults of Dampfomyia beltrani have been collected principally in caves ( Williams, 1976a , b ; Montes de Oca-Aguilar et al ., 2013a), where the temperature is relatively constant and humidity very high. Althought this species can be classified as subtroglophiles species, all intentions to collect immatures in this type of ecotope have been infructuose. TABLE 8.
