description: 7. Chryasus bruniceps (Bondar), new combination
(Fig. 32)
Amphibaris bruniceps Bondar (1946: 101, description), Vaurie (1953: 9, discussion of located specimens).
Sphenobaris bruniceps: Wibmer & O’Brien (1986: 292, with reference to Kuschel 1983).
Diagnosis. Chryasus bruniceps is a stout, entirely brown species with vermiculate pronotum. It is most similar to two unassigned specimens with more medially inserted antenna, the one from Fonte Boa in Amazonas, Brazil (SNSD) being 3.4 mm long, the other from near Cariari in Limón, Costa Rica (MNCR) being 2.4 mm long (Fig. 33).
Material examined. BRAZIL. Bahia, Agua Preta, 1938, 6 specimens (AMNH).
Notes. Kuschel (1983) synonymized Amphibaris Casey, 1922 with Sphenobaris Champion, 1909 based on his studies of the respective type species made during the late 1940s. This paper was published to resolve protracted taxonomic and nomenclatural issues in preparation for the upcoming catalogue by Wibmer & O’Brien (1986). Wibmer & O’Brien (1986) applied this synonymy to all four species previously included in Amphibaris. Baridius ignavus Boheman, 1844 and Amphibaris dispar Bondar, 1946 are transferred here from Sphenobaris to Glyptobaris Casey, as Glyptobaris ignava (Boheman) and Glyptobaris dispar (Bondar), new combinations. I have cleaned, remounted and photographed one male A. bruniceps of the series at AMNH (Fig. 32). As already mentioned by Vaurie (1953), the collecting date on the label disagrees with that given in Bondar (1946).

http://zoobank.org/ urn:lsid:zoobank.org:act: 8F74C8F0-CB1A-40F1-86CC-AF2A2E1F127A
Diagnosis. This is a small, slender, black species with some yellow hairs (Fig. 38). Other elongate species in the same mountain range are stouter and almost always with red or yellow color pattern. All of them need further study.
Description. Total length 2.6–2.9 mm, width 1.1–1.2 mm (n=3); integument mostly black, appendages with some red; body elongate, humeri almost flush with subconical pronotum, disc densely vermiculate, flanks smoother with coarse shallow ridges; elytron 3.0x longer than pronotum, disc at base with transverse depression, interstriae ridged, metaventrite tumid with basally deep discrimen, male ventrites 1, 2, 5 and metaventrite depressed medially, 1, 2 and 5 with erect squamulae; femora with 1 distinct and several minute denticles; male genitalia as Fig. 17, endophallus without flagellum but with elongate sclerite homologous with basal appendage of flagellum of other species.
Material examined. Holotype male, labeled “ Costa Rica: Puntarenas, Finca Eddie Serrano, km 71 Pan Am Hwy., 2600 m, 9° 38′ 25″ N 83° 51′ 04″ W, 22.III.2003, R. Anderson ” (CMNC). Paratypes (1 male, 1 female): same data, dissected male (JPPC), female (CMNC).
Etymology. The name is a Latin adjective meaning thin. It refers to the general appearance of the species and is a reference to the nemonychid Atopomacer Kuschel, the genus actually targeted at this site by Carlos Viquez, Bob Anderson and myself.

http://zoobank.org/ urn:lsid:zoobank.org:act: 11786285-D2B4-4B2F-81D3-A3D874FFBF58
Diagnosis. This species and the Costa Rican C. montyi have the same size and shape, a pronotum with elevated narrow interspaces between fine, coalescent punctation and similar male genitalia (Figs. 18, 19). They differ in color and C. taironius has the pronotal flanks more evenly punctate. Chryasus carinulosus is another similar, plain brown species. Chryasus persimilis has shorter appendages.
Description. Total length 2.9–3.4 mm, width 1.2–1.4 mm (n=4); integument variously reddish brown to black, legs partially and elytron entirely fawn; body oblong ovate with protruding humeri and curved sides; rostrum sexually dimorphic, thinner and longer in female; pronotum with fine, confluent punctation, interspaces forming narrow ridges (indistinct in female), surface texture coarser and shallower on flank; elytron with transverse depression at base, interstriae ridged, metaventrite unmodified and not sexually dimorphic, male ventrites 1, 2 and 5 depressed medially and with erect squamulae; femora with denticles gradually decreasing in size (male) or minute and subequal (female); male genitalia as Fig. 18, endophallus with long, basally inflexible flagellum.
Material examined. Holotype male, labeled “COLOM[BIA]. Magd[alena]., 7000′, San Lorenzo, 41 km. S Sta. Marta, V-10-1973, Campbell & Howden” (CMNC). Paratypes (2 males, 1 female): same site as holotype, Howden & Campbell, 1.v.1973, 1 dissected male (CMNC), 5.v.1973, 1 female (CMNC), 7.v.1973, 1 male (JPPC).
Etymology. The name is a Latinized adjective derived from that of the native, Pre-Colombian Tairona tribes.
Notes. The only available female deviates from the three males. It is somewhat larger, almost entirely black except for the fawn elytron, the pronotal ridges are fragmented and the rostrum has a pit in front of each eye. A male of a smaller species (Fig. 48) was captured at the same site (CMNC).

(Figs. available at https://collections.nmnh.si.edu)
Psiona carinulosa Casey (1922: 274 and 320, key and description).
Diagnosis. This elongate brown species forms a morphologically uniform complex together with C. montyi, C. persimilis and C. taironius. Chryasus montyi is darker than C. carinulosus, the others are reddish.
Material examined. Brazil, Pará, received from Desbrochers des Loges, 1 male, holotype (USNM).
Notes. Chryasus carinulosus is known only by the holotype. I dissected and documented in detail three morphologically similar species from Central America and one from Colombia, to support future examinations of South American material. Presently available, morphologically similar specimens from the Amazon basin and Trinidad Tobago, all singletons, are insufficient to resolve the taxonomy of this species.

Diagnosis. Chryasus montyi is an elongate, brown species very near to but darker than C. carinulosus from Brazil. Chryasus persimilis, the only other morphologically similar species recorded from Costa Rica, is smaller, reddish and with a shorter rostrum.
Description. Total length 2.9–3.3 mm, width 1.2–1.4 mm (n=21); integument nearly black, appendages, elytron and often pronotum brighter with purplish hue; body oblong ovate with protruding humeri and curved sides; rostrum sexually dimorphic, thinner and longer in female; pronotum with fine, confluent punctation, interspaces forming narrow ridges, surface texture coarser and shallower on flank and evanescent above coxa; elytron with transverse depression at base, interstriae ridged, metaventrite unmodified and not sexually dimorphic, male ventrites 1, 2 and 5 depressed medially and with erect squamulae; femora with denticles gradually decreasing in size, denticles occasionally scattered or in seemingly additional row; male genitalia as Fig. 19, endophallus with long, basally inflexible flagellum.
Material examined. Holotype male, labeled “ COSTA RICA, Puntarenas: Monteverde, Est. Biológica, 10.3147 N, 84.7969 W, 1500–1800 m, 30.vi.–9.vii.2009, J. Prena (MNCR). Paratypes (11 males, 9 females): same data as holotype, 1 male, 1 female (CMNC), 4 males, 1 female (JPPC), 1 male, 2 females (MNCR), 1 male, 1 female (NHMUK), 2.–7.vi.2011, 3 males, 3 females (JPPC), 1 male, 1 female (MNCR).
Life history. All specimens were collected at two occasions from the same two flowering Miconia shrubs in a dense secondary forest. They occurred together with C. clunis and in 2009 with a single female of a still unnamed species.
Etymology. The species is named for the late Montgomery “Monty” Wood, valued friend and founder of Monteverde Biological Station. This hospitable research and education facility is not to be confused with the commercial tourist reserve of the former Quaker community, which did not cooperate with official inventory programs.

Life history. In March 1996, I found many specimens on a flowering, unidentified Melastomataceae in an open habitat near Pitilla field station in Área de Conservación Guanacaste, Costa Rica.
Notes. This is the type species of Chryasus. A lectotype designation for it is not warranted at present because the two syntypes are from the same locality and do not threaten nomenclatural stability. Specimens from higher elevations are more elongate with a smaller prothorax (often with a median carina) than specimens from the lowlands.

Psiona densa Casey (1922: 321, description), Davis (2011: 153, character matrix).
Psiona opaca Casey (1922: 321, description); new synonymy.
Diagnosis. Chryasus densus is an elongate, 2.4–2.8 mm long species with a coarsely, somewhat confluently punctate pronotum as in C. cavernosus, but lacks a deeply punctate pronotal collar.
Material examined. BRAZIL. Mato Grosso: Chapada dos Guimarães, 1882–1886, H.H. & A. Smith, syntypes of P. densa (USNM 4), holotype of P. opaca (USNM).
Notes. Psiona opaca is a small female of P. densa, not a distinct species. All five specimens known to me were collected by Herbert H. Smith and his wife while on contract with the Museu Nacional, Rio de Janeiro. Smith violated the contract by illegally exporting more than 300,000 arthropod specimens to the United States and subsequently selling them to the Carnegie Museum and numerous private collectors (Kunzler et al. 2011), among them Casey. Holland (1919) seems to have been under the impression that he and his museum had acquired Smith’s permitted share of duplicate specimens, which was the case for everything else but not for the arthropods. None of the latter material was ever returned and, without question, this issue has contributed to the present strict export policy by Brazilian authorities.

http://zoobank.org/ urn:lsid:zoobank.org:act: CC09D1B3-9FFE-4F8C-9EB7-89E95A43BA2F
Diagnosis. This species is most similar to C. carinulosus, C. montyi and C. taironius. They all have similar body proportions and similar male genitalia (unknown for C. carinulosus). Chryasus clunis is another superficially similar species with the same color, but it is less elongate and the male has a tumid distal ventrite. Chryasus persimilis can be distinguished from all these by its stout rostrum and femora, which measure distinctly less than twice the head diameter.
Description. Total length 1.9–2.5 mm, width 0.8–1.1 mm (n=24); reddish brown, elytron somewhat brighter; body oblong ovate with protruding humeri and curved sides; rostrum 2x as long as eye; pronotum nearly as long as wide, interspaces forming indistinct oblique ridges between non-confluent punctation, flank with larger and more distant pits in smooth area; elytron 2.1x longer than pronotum, disc at base with very subtle transverse depression, interstriae ridged, metaventrite neither modified nor sexually dimorphic, male ventrites 1, 2 and 5 depressed medially and with erect squamulae; femora with 1 distinct and several minute denticles (Fig. 7); male genitalia as Fig. 24, endophallus with long, flexible flagellum.
Material examined. Holotype male, labeled “Est. Pitilla, 700 m, 9 km S Sta. Cecilia, P.N. Guanacaste, Prov. Guan., COSTA RICA, C. Moraga, Jul 1991, L-N-330200, 380200”, “INBIO CRI000 358585” (MNCR).

Cerro Campana, 28.4.1973, H. Hespenheide, 1 dissected male (JPPC).
Life history. I found this species in numbers on a flowering, unidentified Melastomataceae in an open habitat at the Pitilla field station, together with C. cavernosus.
Etymology. The name is a Latin adjective.

description: Genus Myrsidea Waterston
Myrsidea Waterston 1915:12. Type species: Myrsidea victrix Waterston by original designation.
A thorough characterization of this genus may be found in Clay (1966). We provide here only the diagnostic characters that are of significance in defining the genus as it pertains to the tyrannid lice.
Head (Fig. 5) evenly rounded anteriorly; lacking lateral slit or notch; with long inner occipital setae, minute outer; without ventral sclerotized processes; gula usually with 4–5 setae on each side, less often 3 or 6, with heavier longer posterior seta; hypopharyngeal sclerites well developed.
Thorax (Fig. 5) with pronotum lacking central setae; with 3 short setae at each lateral angle and 6 longer posterior marginal setae. Mesonotum well defined, with 2 minute medioanterior setae adjacent to postnotum and 2 minute setae at posterior margin. Metanotum without central setae, but with 6 short setae around periphery. Prosternal plate well developed, elongate, with 2 short anterior setae; mesothorax with notum, pleura, and sternum fused to form strongly sclerotized ring; metasternal plate prominent, diamond shaped, usually with 6 setae, much less often 5, 7, or 8; venter of femur III with setal brush.
Abdomen with undivided tergites, without anterior setae except for very small seta at corner of each side of tergite I (not included in tergal count); sternite I small, usually without setae; sternite II enlarged, with aster of heavy setae at each posterior corner. Female anus oval, without inner setae; subgenital plate of fused sternites VII–IX, usually with lightly serrated posterior margin. Male subgenital plate of fused sternites VIII–IX; genitalia of characteristic shape (Fig. 6), with spinous sac having distinctively shaped associated sclerite.
Sexual dimorphism is limited to males having smaller dimensions, sparser abdominal chaetotaxy, and differences of the posterior abdomen. Some females may have enlargement of anterior abdominal tergites. Male tergites are unmodified, with pattern of postspiracular setal lengths much as for female. Characters listed above for the genus will not be repeated in the species descriptions.

Myrsidea magnidens

description: magnidens species group
The two species of this group, representing the only previously described species of Myrsidea from the Tyrannidae, are characterized as having both sexes with a much larger number of abdominal tergal and/or sternal setae than any other known species from this family. The females have only a modest enlargement of the anterior abdominal tergites (Figs. 1, 3). Although the host identities of both species are uncertain, this group is morphologically distinctive from other Myrsidea species with known host associations with the Tyrannidae.

Type material. Holotype female (OSU), ex T. verticalis, Stillwater, Oklahoma, U.S.A., 5 Jun 1948, K. C. Emerson. Paratypes (OSU, TNHM): 19 females, same data as holotype.
Remarks. Though we have only females available for this description, the uniformly very long postspiracular setae on I–VIII, in combination with the number of tergal and sternal setae and the large dimensions, readily separate Myrsidea seversoni from others of this species group.
Etymology. This species is named for David W. Severson, University of Notre Dame, in recognition of his many contributions to our understanding of the role of mosquitoes in disease transmission.

Type material. Holotype female (NMNH), ex T. melancholicus, TRINIDAD: Fort Read, 2 Jul 1954, T. H. G. Aitken, Lot 54­12322. Paratypes (NMNH, TNHM, RCD), all ex T. melancholicus: TRINIDAD: 1 female, Bush Bush Forest, Nariva Swamp, 28 May 1963, G. Aitken, TRVL 6634; 1 male, Sangre Grande, 24 Dec 1957, W. G. Downs, TRVL 6; COSTA RICA: 1 female, 6 males, Las Cruces Biological Station, Cota Brus, 18–21 Apr 1992, R. L. Fisher 146.
Remarks. Although this species is very close to Myrsidea seversoni, females are separable from the latter by the postspiracular seta on V being distinctly shorter than the ones on IV and VI. The absence of males for M. seversoni makes differentiation for that sex impossible, other than inferring that the postspiracular setae will eventually prove to be similar for both sexes.

Remarks. The male of Myrsidea barbati is readily separated from males of others of this group by its highly distinctive genital sac sclerite (Fig. 10). The female is recognized by its small number of setae on the metanotal margin, in conjunction with not>33 setae on sternites V–VI, not>32 setae in each anal fringe, and the narrow anus <0.20 wide. The small dimensions and the relative lengths of the postspiracular setae for both sexes will also separate this species from a number of the others.
