Un nuevo genero de Epipsocidae (psocodea:'psocoptera'), del valle del Cauca, Colombia, con una re-evaluacion de Goja Navas, 1927.



Casasola Gonzalez (2006) studied the phylogenetic relationships of the genera in the psocopteran infraorder Epipsocetae, that includes the families Dolabellopsocidae, Ptiloneuridae, Spurostigmatidae, Cladiopsocidae and Epipsocidae; in the strict consensus tree of 104 most parsimonious trees (Fig. 124), a clade was recognized, for the latter family, including the genera sp4 THAI, Goja, Rogojiella and Ianthorntonia. The former genus was later described as Phallofractus (Garcia Aldrete, 2009). In this clade, the males have either caeciliusid venation, with Rs-M in the hindwing fused or joined by a crossvein, or they have supernumerary venation on both wings; in these genera, the phallosome is complex, in most cases with two pairs of endophallic sclerites. Phallofractus is Oriental; it is known only from one male; the arms of the aedeagal arch are separated and the phallosome has only one pair of endophallic sclerites (Garcia Aldrete 2009), it is believed to constitute the sister group of the other three genera, which are neotropical (Casasola Gonzalez & Garcia Aldrete 2002, Garcia Aldrete 2004 a and b). The females of Goja and Ianthorntonia (female unknown in Rogojiella), are either brachypterous or apterous, with v1 directed posteriorly from their junction with the clunium. In both sexes, the head is not decidedly elongate, the compound eyes, in most of the species do not protrude beyond the level of the vertex, and the outer cusp of the lacinial apex is diagonal.

Recently, Ranulfo Gonzalez Obando and Nancy Soraya Carrejo, of the Biology Department, Universidad del Valle, Santiago de Cali, Colombia, showed to me some specimens collected by them near Cali, in an area of cloud forest. These specimens clearly belong in the clade indicated above, but they are not assignable to any of the genera of the clade, thus representing an undescribed genus; the purpose of this work is to describe it and illustrate it, and to assess the relationships with the other genera in the clade; also, the genus Goja Navas is re-evaluated, and a new genus is erected from a fraction of it.


28 males and 12 females were available for study. Two specimens of each sex were dissected in 80% ethyl alcohol, and their parts (head, right wings and legs and genitalia) were mounted on slides in Canada Balsam. Color was recorded by placing whole specimens in 80% ethyl alcohol under a dissecting microscope, illuminated with white, cold light, at 80X. Measurements, in Lim, of parts on the slides, were taken with an AO filar micrometer. Abbreviations of parts measured, or counted, are as follows: FW and HW: lengths of fore- and hind-wings, F, T, t1 and t2: lengths of femur, tibia and tarsomeres 1 and 2 of right hind leg, ctt1: number of ctenidobothria on t1, Mx4: length of fourth segment of right maxillary palp, IO, D and d respectively: minimum distance between compound eyes, antero-posterior diameter and transverse diameter of right compound eye in dorsal view of head, PO: d/D. The types are deposited in the Entomological Museum of the Universidad del Valle, Santiago de Cali, Colombia (MUSENUV). One paratype of each sex is deposited in the National Collection of Insects (CNIN), Departamento de Zoologia, Instituto de Biologia, Universidad Nacional Autonoma de Mexico, Mexico City.

To assess the relationship of the new genera in the clade with the other genera, a matrix was built utilizing the 15 characters shown in Table 1; in the matrix (Table 2), Bertkauia was the outgroup. Goja was split in two groups: Goja, for species with males having supernumerary venation in both wings, and Gojaoides gen. n., for species with males having caeciliusid wing venation (see section on re-appraisal of Goja below). A parsimony analysis using NONA (Goloboff, 1999), was conducted. Three trees were generated utilizing an heuristic search. The characters parsimony informative, were treated initially as unweighted and unordered; the trees were rooted by the outgroup method; the characteristics of the strict consensus tree are the following: L= 16 steps, consistency index (CI)= 0.50, and retention index (RI)=0.27.

Etymology. The genus name is a compound noun, of female gender, formed with the two last names of Ranulfo Gonzalez Obando, of the Universidad del Valle, Santiago de Cali, Colombia. The species name derives from the first name of Nancy Soraya Carrejo, of the same institution. Gonzobandia nancyae is dedicated to them, in recognition to their strong and energetic impulse to survey and study the Psocoptera of Colombia, mostly of Valle del Cauca, Cauca and Caldas.

The position of Gonzobandia in the clade

The strict consensus tree is presented in Fig. 20, the relationships of the genera in the clade are unresolved, except for Goja and Ianthorntonia; the clade is monophyletic, supported by two synapomorphies: endophallus radular or with sclerites (5-1), and external parameres membranous or well defined projections (7-1). On basis of the three most parsimonious trees found (Fig. 21), two hypotheses are presented, as to whether Phallofractus or Gonzobandia constitute the sister group to the other genera in the clade; on geographical grounds, it would seem sensible to consider the former as the sister group to the rest of the assemblage, and it so appears in two of the three most parsimonious trees. In one of three trees, Gonzobandia is the sister group to the rest of the assemblage. The position of Gojaoides as sister group to Rogojiella-Goja-Ianthorntonia, in two of the trees is also sensible, (Fig. 21), as the latter pair shares having supernumerary venation in the male forewing, and Rogojiella, as well as Gojaoides, have caeciliusid wing venation. It would appear, to resume the above, that the third most parsimonious tree found, best represents the relationships of the genera in the clade.

A re-appraisal of Goja Navas, 1927

The species presently recognized in Goja Navas, 1927 (see Casasola Gonzalez & Garcia Aldrete, 2002), are assignable in two well defined groups, based on male wing venation characters, as follows:

Group I. Male forewing venation supernumerary, in the branches of Rs, M, or both. The hindwing venation may be either caeciliusid, or with Rs 2-branched and M supernumerary, or with both Rs and M with supernumerary veins. In all cases, hindwing veins Rs and M are joined by a crossvein.

Group II. Both male wings with venation caeciliusid (forewing Rs 2-branched, M 3-branched; hindwing Rs 2-branched, M simple). In all cases, hindwing veins Rs and M are joined by a crossvein.

In both groups the females are neotenic, lacking ocelli, or these at most represented by light spots, the coxal organ is little developed or absent, and t1 of hind legs lacks ctenidobothria. They are mostly brachypterous or apterous, lacking hindwings. The subgenital plate is simple, setose, and the ovipositor valvulae are complete in all but one species; the ninth sternum is distinct, almost circular, with the spermapore often distal, surrounded or not by a pigmented ring. The epiproct and paraprocts are elongate, with long setae distally; the paraprocts have a small sensory area not well defined, bearing 2-10 trichobothria issuing from basal rosettes, one or two longer than the others; only one species lacks basal rosettes (Casasola Gonzalez & Garcia Aldrete, 2002).

Also in both groups the males are similar, other than the differences in wing venation, and can be succinctly diagnosed as follows: Compound eyes normal, occasionally elevated beyond the level of vertex. Ocelli generally conspicuous. Distal inner labral sensilla: one central placoid, flanked at a distance by a close pair trichoid-placoid. Outer cusp of lacinial apex generally broad, with 3-8 denticles; t1 of hind legs with well developed ctenidobothria.




Pretarsal claws with one preapical denticle, pulvillus filiform, acuminate. Macropterous, as indicated above. Hypandrium simple, of two parts, the posterior one generally with a median posterior concavity, and side fields of long setae on postero-lateral corners. Phallosome open or close anteriorly; side struts straight or curved, often fused to the aedeagal arch, this with apex variable; external parameres as pore bearing lobes, membranous or slightly sclerotized, partially immersed in the endophallus. One or two pairs of endophallic sclerites, occasionally with one central sclerite. Epiproct trapeziform, with a field of spicules along posterior border, a field of setae on each side, and 1-3 mesal macrosetae, towards anterior border. Paraprocts broad, almost rounded, each with a large sensory field, with 20-42 trichobothria issuing from basal rosettes, occasionally 1-2 central trichobothria without basal rosettes (Casasola Gonzalez & Garcia Aldrete, 2002).

For Group I, I propose to retain the name Goja Navas, since the type species of the genus (male), Goja ditata Navas, 1927, has both wings with supernumerary venation (see Fig. 9.a in Navas, 1927). The species included are the following:


G. acuphallica, G. brailovskyana, G. circumvittata, G. chilensis, G. curvata, G. eertmoedi, G. guatemalensis, G. herrerae, G. longispinosa, G. martinezi, G. medellini, G. mockfordi, G. montieli, G. moyai, G. obrienorum, G. ochoterenae, G. ocotensis, G. oculatissima, G. omiltemensis, G. poblana, G. reticulata, G. reticulatoides, G. spinosissima, G. ticana, G. venezuelensis, and G. vittata (all by Casasola Gonzalez & Garcia Aldrete).

Type species: Goja ditata Navas.

The species Goja bimaculata, G. pallida and G. trinidadensis, all by Casasola Gonzalez & Garcia Aldrete, are only known from females; on the basis of similarities with females of Goja, they are tentatively assigned in that genus. The finding of males of these species will confirm, or reject, this placement.

For Group II, I propose to create the genus Gojaoides gen. n., as diagnosed above, and including the following species:

Gojaoides aviceps (Badonnel), n. comb., G. bogotana (Roesler), n. comb., G. cubitalis (Mockford), n. comb., G. pechi (Williner), n. comb., G. molinai (Williner), n. comb., G. nebulosa (Roesler), n. comb., G. plaumanni (Roesler), n. comb., G. semiaptera (Mockford), n. comb., G. cornuta, G. erwini, G. latiphallica, G. longiareola, G. robusta and G. spiculata (all by Casasola Gonzalez & Garcia Aldrete).

Type species: Gojaoides picta (Banks), n.comb.

Several autapomorphies are presented by Gonzobandia (characters 10, 12, 14 and 15 in Table 2, plus the simple phallosome, the endophallic "radula", v1 bent proximally at 90[degrees], and the distally straight outer cusp of the lacinial tip). It differs from the other genera in the clade by the autapomorphies listed above, keeping, in one of three most parsimonious trees found, a sister group relationship with the assemblage Gojaoides-Rogojiella-Goja and Ianthorntonia. Gonzobandia nancyae is a montane species, with distribution probably restricted to a small area in Valle del Cauca, Colombia, it lives on tree trunks densely covered with mosses and runs rapidly when disturbed. The small area of distribution and the peculiar biotope it inhabits, makes it vulnerable with respect to anthropogenic changes of the habitat.


I am most grateful to Ranulfo Gonzalez Obando and Nancy Soraya Carrejo (Departamento de Biologia, Facultad de Ciencias Naturales y Exactas, Universidad del Valle, Santiago de Cali, Colombia), for making available for study this interesting species. I also thank Felipe Villegas Marquez (Instituto de Biologia, Universidad Nacional Autonoma de Mexico) for support with the plates of illustrations. Especial thanks are extended to Martin Leonel Zurita Garcia, of the same institution, for advice in cladistics and for running in NONA the matrix of the genera in the clade studied.
