Brachypogon (Brachypogon) bifidus Spinelli and Grogan Brachypogon (Brachypogon) bifidus Spinelli and Grogan, 1998: 66 (Dominica); Borkent and Spinelli 2000: 45 (in New World catalog south of the USA; distribution); Borkent and Spinelli 2007: 78 (in Neotropical catalog; distribution). Discussion. This small Neotropical predaceous midge was described by Spinelli and Grogan (1998) from Dominica (type locality) and El Salvador. It is unique among other species in the Brachypogon (B.) impar complex in having a wing with a darkly infuscated membrane and a dark spot distad of the r-m crossvein and a pale spot beyond the dark spot, males are the only species with parameres having a bifid apex, and the antennal flagellum of females with 12 flagellomeres due to a fusion of 12-13.

Brachypogon (Brachypogon) woodruffi Spinelli and Grogan
Brachypogon (Brachypogon) woodruffi Spinelli and Grogan Brachypogon (Brachypogon) woodruffi Spinelli and Grogan, 1998: 72 (Dominican Republic); Huerta and Borkent 2005: 118 (Mexico records); Borkent and Spinelli 2000: 46 (in New World catalog south of the USA; distribution); Borkent and Spinelli 2007: 79 (in Neotropical catalog; distribution); Spinelli and Marino 2008: 124 (record from Peru); Swanson and Grogan 2011: 536 (records from Cayman Islands and Florida). Discussion. Spinelli and Grogan (1998) described this very small predaceous midge from the Dominican Republic, and soon after, Huerta and Borkent (2005) recorded it from the Yucatan Peninsula, Mexico, and Spinelli and Marino (2008) reported it from Peru. Grogan et al. (2010) listed additional specimens from Florida and the Cayman Islands in the FSCA. Swanson and Grogan (2011) described and illustrated additional details of the male genitalia and listed new records from the USA in Florida and the Cayman Islands, described and illustrated a similar related new species from Alabama and Florida (B. laneae), as well as another related species from Florida that they did not name (sp. 9B). Our identification of a single female from Guadeloupe as this species is somewhat tentative despite that it has an antennal flagellum with only 12 flagellomeres due to fusion of primitive 12-13 and very small flagellomeres 4-7, both of which are characteristics of females of B. woodruffi. However, it lacks the partial fusion of flagellomeres 3-4 which is another character of females of B. woodruffi. Spinelli and Grogan (1998) also noted that in this species the wings of females only have 6-7 marginal costal setae, whereas males only have 3 marginal costal setae that are located over their coalesced radial cells (stigma). WLG examined 20 females (including the allotype) and 10 males (including the holotype) of B. woodruffi from the Cayman Islands, Dominican Republic and Florida and recorded 3-4 costal setae in males and 5- 9 costal setae in females. He also examined 5 males and 19 females of B. laneae Swanson and Grogan from Florida as well as the male and female of their unnamed species 9B from that state and recorded 3 costal setae for males of both species and 5-10 costal setae in females of B. laneae and 5-6 setae in the female of sp. 9D. Our Guadeloupe female has 11-12 costal setae, a greater number than previously recorded for females of this species and the very similar, related B. ecuadorensis Spinelli and Grogan that is known from Belize, Colombia, Costa Rica, Ecuador (type locality), Jamaica and Panama, the females of which have 5-9 costal setae. In addition, females of B. ecuadorensis also have an antennal flagellum with 12 flagellomeres (12-13 fused), however, flagellomeres 3-4 are not partially fused and flagellomeres 2-9 are all similar in size, the wing lacks vein M 2 and has a slightly shorter costa (Costal Ratio 0.41-46 vs. 0.44- 46 in B. woodruffi). Finally, males of B. ecuadorensis have an aedeagus with median longitudinal wrinkles, a feature not present in males of other species in the B. woodruffi complex, and their wing also lacks vein M 2. We provide the first records of B. woodruffi from Guadeloupe. New records.

Localized expression of Strim1, a novel member of the TRIM-containing family, guides the skeletal morphogenetic program of the sea urchin embryo
The building of the skeleton in the indirect
developing sea urchin embryo is a complex
morphogenetic process that is executed by the
Primary Mesenchyme Cells or PMCs (Ettensohn et
al, 1997; Wilt 2002). It is well known that the
PMCs acquire most of the positional and temporal
information from the overlying ectoderm for
skeletal initiation and growth (Armstrong 1993;
Cavalieri et al, 2003; Röttinger et al, 2008). In this
study, we analyze the function of a novel gene,
encoding for a tripartite motif-containing (TRIM)
protein denoted strim1, that adds up to the list of
genes constituting the epithelial-mesenchymal
signaling network.
We show that strim1 is expressed in ectoderm
regions adjacent to the bilateral clusters of PMCs.
Strim1 misexpression causes the number of PMCs
to double and leads to skeletal abnormalities. By
micromere transplantations, we establish that
skeletal defects depend upon strim1 misexpression
in ectoderm cells. Reciprocally, knock-down of
strim1 function abrogates PMC migration and
blocks skeletogenesis. Identical phenotype is
shown by chimeras in which strim1 function is
blocked selectively in the ectoderm. We also show
that clonal expression of strim1 into ectoderm cells
from knocked-down embryos restores the correct
skeletogenic program. Finally, we report that
strim1 triggers the expression of the ectodermspecific
gene pax2/5/8, and the PMC marker sm30
(an ectoderm signaling dependent gene).
We conclude that strim1 function is able to elicit
specific gene expression both in ectoderm cells and
PMCs to guide the biomineralization during
morphogenesis.

Fourth segment (Fig. 42) with sensillar pattern as follows: dorsal tubercles with small base: D- 1 -IV, D- 3 -IV absent, D- 2 -IV very short seta, D- 4 -IV, D- 7 -IV campaniform sensilla, D- 5 -IV, D- 8 -IV, D- 9 -IV minute setae, V- 5 -IV, V- 6 -IV without visible setae, on notorious tubercles; L- 1 -IV absent, L- 2 -IV, L- 3 -IV short, stout setae, on triangular pointed tubercles. Segment 9 (Fig. 36) approximately 1.83 X longer than greatest width, length 0.275 mm, width 0.15 mm; posteriorly directed spicules restricted dorsally to mesal area, terminal processes triangular, these moderately elongated, subparallel, pointed; ventral surface of processes spiculated, terminal procceses length 0.125 mm, width 0.05 mm, D- 5 -IX, D- 6 -IX campaniform sensilla (Fig. 36), genital lobe moderately long and globose, extending under posterior margin. Female pupa (Figs. 35, 37). Similar to male with usual sexual differences: CTL 0.90 mm. First abdominal segment (Fig. 35) with setae: D- 2 -I minute seta, D- 7 -I and L- 1 -I not in position to describe, D- 5 -I very short seta, D- 9 -I minute seta on flattened tubercle, D- 8 -I very short seta. Segment 9 (Fig. 37) length 0.325 mm, width 0.175 mm; terminal processes length 0.125 mm, width 0.05 mm. Distribution. Brazil (Mato Grosso), Argentina (Misiones). Taxonomic discussion. Parabezzia brasiliensis is one of the 25 species inhabiting the Neotropical region. Of these, only are known the pupae of P. alexanderi Wirth and P. balseiroi Spinelli & Grogan. Fourteen species, including P. brasiliensis, are known only from female adults. There are two quite different types of pupae in Parabezzia. One has number of rounded tubercles, the other called alexanderi group, has sharp tubercles and abdominal sternites with membranous discs (Borkent, 2014). Parabezzia brasiliensis perfectly fits in the alexanderi group and is very similar to P. b al s ei roi, but in the latter species the DAW/ DAL ratio is lower (2.26 for male, 3.60 for female), the DA- 1 -H is a minute seta on well developed tubercle, and the respiratory organ bears 10–12 apical opening pores. The adult male of P. brasiliensis is easily distinguished from their congeners inhabiting the Americas by the obliterated radial cell and by the costal fringe limited to 5 setae. The aedeagus is very similar to the one illustrated by Grogan & Wirth (1977, page 73) for the Nearctic species P. inermis (Coquillett), but in the latter the radial cell is open, the costal fringe is complete and the parameres are apparently absent. Pupae of this specie was collected associated with pupae of Bezzia blantoni Spinelli & Wirth and and Bezzia brevicornis (Kieffer). Specimens examined.
