Thorax: Cervical sclerite flat and dull, with lateral indentation and small anterolateral vertical carina; proepisternum with a few long marginal ventral setae on posterior 1/2; katepisternum with double row of thin black setae, anterior row with only 5 setae, barely overlapping with lower end of posterior row; scutellum with 1 pair of marginal setae only, 1 small to minute seta between postalar and dorsocentral setae.
Unstained, unflattened specimens mounted in glycerine were used to obtain the measurements of the internal organs (pharynx and gonads), the body and the haptoral sclerites. The terminology is that of Gusev (1976b), with two modifications; the term "thumb" and "shank" are used instead of "heel" and "handle" of hooks, respectively.
Both homonymical and synonymical usage abounds with anatomical terminology of insects, namely Heteroptera, such as "antennal tubercle, antennal sclerite, antennifer, antenniferous tubercle, antennal socket, torus, torulus." We apply here a simple English terminology.
Diagnosis.--Males can be recognized by embolus with thread originating near base of tegular sclerite, and females by widely separated epigynal teeth and posteriorly extended spermathecal heads (Figs.
The results showed that the length and width of mouth hooks and of the pharyngeal sclerite exhibited 3 distinct distribution areas (Fig.
Distal sclerite (DMS) of pedipalp simple and in median position, broadly fused to tegulum and conducting embolus medially and distally, often with additional sclerotizations in a basal position (e.g.
Analysis of variance (ANOVA) and post hoc Tukey's honestly significant difference (HSD) tests were used to identify differences in sclerite length in samples from different depths.

It is placed in the subgenus Sternolaboides Legalov, 2007 because the humeri without tooth, apex of the elytra without blades, pronotum without protuberance or tooth near apex, rostrum shorter than pronotum, and the basal sclerite of the endophallus almost symmetric.
The genus Colpocephalum, as found on the Accipitriformes, is characterized by combs of short spiniform setae restricted to the venter of femora III and abdominal sternite III, but the ventral sclerites bearing setae between the vulva and anus are absent in females.
The Kruskal-Wallis analysis showed significance for 6 variables: the Ibague and Pensilvania individuals showed greater body width; populations from higher altitude showed larger cephalopharyngeal sclerites and larger ventral apodemes; the anterior spiracles from the Duitama and Pensilvania individuals were longer; and those of Sibundoy were smallest (Fig.
The present specimen is assigned to an undescribed genus of the family Misophriidae based on the following features: (1) the carapace-like extension covering the first pedigerous somite; (2) the reduction in segmentation (6-segmented) and setation (0, 2, 1, 1, 1, 3) of the antennary exopod; and (3) the absence of an intercoxal sclerite on the fifth legs (see Boxshall and Jaume 2000).
